    Effect of Plant Growth Regulators on Growth, Flowering and Quality of Gerbera (Gerbera Jamesonii Hook.) Cv. Sangria Under South Gujarat Conditions
    (Floriculture and Landscaping Department, Aspee College of Horticulture and Forestry Gujarat Agriculture University, Navsari, 2001-10) Patil, Sagar Janardan; Dhaduk, B. K.
    The effect of various plant growth regulators on gerbera (Gerberajamesonii Hook.) cv. "Sangria' was studied during the year 2000- 200 \ at the Ornamental Plant Nursery, ASPEE College of Horticulture and Forestry, Gujarat Agricultural University, Navsari. The treatments comprised three different concentrations ofGA, (50. \00 and \50 ppm). NAA (50, 75 and 100 ppm) and BA (50, 100 and 150 ppm). The experimentwas laid outin Completely Randomized ;h'k Design (CRD) with nine pots per treatment. In each treatment, the plants were sprayed twice, 40 and 60 days after transplanting. The results revealed that effect of all plant growth regulators used in the experiment was found positive, however GA3 at 150 ppm produced the maximwn plant height, plant spread and leaf area and the minimum plant height and plant spread was recorded under control. SA at150 ppm gave maximum number of leaves and the minimum was noticed under control. An the levels of GA) gave earlier flowering while NAA at aU levels significantly delay flowering than control. The largest flower size, better ",ore.. belte ... longest stalk iength,,$irth of flower stalk, . . . number of flower and"weight of flower was registered with GAl at 150 ppm and all the characters were minimwn Wlder control. BA at 100 ppm recorded the longest vase life of flowers. From the results of investigation it can be concluded that all the above plant gromh regulators had beneficial effect over control in respect to vegetative and flowering characters. Although spraying of GA) at 150 ppm, 40 and 60 days after transplantmg is more beneftcial for vegetative growth and flower characters viz., plant height, plant spread, teaf area, flower initiation, sta lk length, stalk girth, flower diameter, number of flowers and weight of flower, BA at 100 and 150 ppm is more beneficial for vase life of flower and number of leaves per plant, respectively.

    (DEPARTMENT OF FLORICULTURE & LANDSCAPE ARCHITECTURE ASPEE COLLEGE OF HORTICULTURE AND FORESTRY NAVSARI AGRICULTURAL UNIVERSITY NAVSARI, 2017-06) Patel, Unnatiben R.; Patil, Sudha
    The present investigation entitled Post harvest studies in different varieties of heliconia was carried out at Laboratory, Department of Floriculture and Landscape Architecture, ASPEE College of Horticulture & Forestry, Navsari Agricultural University, Navsari in the year 2015-2016. The experiments were laid out in Completely Randomized Design with Factorial concept (FCRD) and replicated thrice. To study the post harvest life of heliconia inflorescence. Experiment 1 entitled ‘‘Standardization of harvesting stage for different varieties of heliconia’’ was conducted to standardize harvest stages for different varieties of heliconia. There were twelve combinations comprising of four varieties (V1- Red Torch, V2- Golden Torch, V3- Kenea Red and V4- Orange) and three stages of harvesting (S1- First bract open, S2- Second bract open and S3- Third bract open). Varieties of heliconia significantly influenced at all post harvest quality and vase life parameters except number of bract open and flower opening percentage. Variety V2 (Golden Torch) recorded maximum water uptake with higher fresh weight retention and maximum useful vase life of 12.00 days. Harvesting stages had significant influence on all parameters recorded during post harvest life in heliconia inflorescence. Harvesting stage S3 (3 bract open) was found most appropriate with respect to maximum water uptake and higher fresh weight retention on alternate day with extended useful vase life (12.04 days). An interaction effect of varieties and harvesting stages was found non significant for all parameters but the maximum score (3.78) for appearance was recorded in flowers of Golden Torch harvested at 3rd bract open stage (V2S3). In experiment 2, study was carried out to standardize pulsing solutions for different varieties of heliconia. There were sixteen combinations including four varieties (V1- Red Torch, V2- Golden Torch, V3- Kenea Red and V4- Orange) and four pulsing solutions (P1- control, P2- 15 % sucrose, P3- 15 % sucrose + 250 ppm 8-HQC and P4- 15 % sucrose + 250 ppm BA). Significant influence of all varieties was noted for all quantitative and qualitative parameters. Among all varieties, Golden Torch (V2) recorded significantly maximum water uptake with fresh weight retention on alternate day, TSS, flower opening percentage, number of bracts open, carotene content and useful vase life (14.60 days). Pulsing solutions had significant influence on all parameters studied during post harvest life of heliconia. Treatment P3 containing 15 % sucrose + 250 ppm 8- HQC recorded significantly maximum water uptake with higher fresh weight retention on alternate day, TSS, flower opening percentage, number of bracts open, carotene content and useful vase life (14.94 days). The results revealed that significantly highest flower opening percentage and useful vase life (15.72 days) was recorded in flowers of Golden Torch variety pulsed with 15 % sucrose + 250 ppm 8-HQC. Moreover, the appearance (4.06) was also found maximum in V2P3. In experiment 3, thirty two combinations comprising of four varieties (V1- Red Torch, V2- Golden Torch, V3- Kenea Red and V4- Orange) and eight treatments of vase solutions (T1- control, T2- 3 % sucrose, T3- 50 ppm GA3, T4- 100 ppm GA3, T5- 200 ppm Al2(SO4)3, T6- 300 ppm Al2(SO4)3, T7- 200 ppm 8-HQC and T8- 300 ppm 8-HQC) were taken to standardize the vase solution for different varieties of heliconia. Significant influence of varieties was observed for all parameters studied during post harvest life of heliconia. Significantly maximum water uptake and higher fresh weight retention on alternate day with maximum TSS, flower opening percentage, number of bracts open, carotene content and useful vase life were recorded in flowers of Golden Torch. Effect of vase solutions was found significant for all parameters on post harvest quality of heliconia during vase life. T4 (100 ppm GA3) treated flowers shown significantly maximum water uptake, fresh weight retention, TSS, flower opening percentage, number of bracts open, carotene content and useful vase life (15.50 days). The interaction effect revealed that varieties and vase solution recorded significant influence where variety Golden Torch treated with vase solution containing 100 ppm GA3 (V2T4) shown maximum flower opening percentage (54.17), useful vase life (16.28 days) and retained maximum score for appearance of flowers (4.28).

Local” was carried out at Floriculture Research Farm, ASPEE College of Horticulture & Forestry, Navsari Agricultural University, Navsari during 2015-2016. The experiment was laid out in Randomized Block Design (RBD) with factorial concept having eight treatment combinations, comprising of two levels of RDF (75 % and 100 % RDF) and four levels of bio-fertilizers (No bio-fertilizers, Azotobacter, Azotobacter + PSB and Azotobacter + PSB + KMB). The treatments were replicated thrice. The response of golden rod to the treatments was evaluated on the basis of growth, flowering and yield characteristics. Among two levels of RDF, application of 100 % RDF (150:100:100 NPK kg/ha) significantly increased all growth parameters like plant height (94.26 cm), leaf area (20.02 cm2), number of suckers per plant (6.66), fresh weight of plant (159.07 g) and dry weight of plant (70.92 g). In flowering, minimum number of days taken for panicle initiation (112.92 days), highest length of panicle (73.90 cm) and vase life of panicle (6.72 days) while in yield, maximum number of panicle per plant (3.98), plot (321.98) and hectare (662.50) and maximum SOC (0.700 %) and microbial population (53.48 2 10-6 CFU/ml) in soil. In case of bio-fertilizers, application of B3 (Azotobacter + PSB + KMB) significantly increased the growth to plant height with panicle (101.32 cm), leaf area (22.45 cm2), number of suckers per plant (7.43), fresh weight (185.81 g) and dry weight of plant (82.50 g). The minimum number of days taken for panicle initiation (108.14) and maximum length of panicle (79.89 cm) and vase life (7.10 days) and yield like number of panicle per plant (4.23), per plot (342.23) and hectare (704.17) were also recorded in B3 (Azotobacter + PSB + KMB), while nitrogen content (190.05 kg ha-1), potassium content (297.11 kg ha-1), SOC (0.718 %) and microbial population (56.90 2 10-6 CFU/ml) was recorded in B3 (Azotobacter + PSB + KMB) as compared to other levels. The experimental results revealed that combined application of chemical fertilizers and bio-fertilizers (F2B3) recorded significantly effect on yield parameters like maximum number of panicle per plant (4.63), plot (376.42), hectare (722.47) and soil parameters like maximum microbial population (62.10 2 10-6 CFU/ml). Application of RDF @ 100 % along with Azotobacter + PSB + KMB (F2B3) was found superior and gave maximum yield of panicle 4.53 per plant, 367.20 per plot and 755.56 thousand per ha (estimated). As far as economics is considered, it is clear that application of 100 % RDF along with Azotobacter + PSB + KMB biofertilizers (F2B3) gave the highest net return of Rs. 524324.76 per ha with BCR of 5.79.

    (Department of Floriculture and Landscape Architecture ASPEE College of Horticulture and Forestry Navsari Agricultural University Navsari, 2017-05) Parvathi, Bennurmath; Bhatt, Dipal S.
    The present investigation entitled “Assessment of genetic diversity in chrysanthemum (Chrysanthemum morifolium Ramat)” was conducted during 2015 – 2016, at the Floriculture Research farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari. The experiment was laid out in Randomized Block Design with fifteen different chrysanthemum varieties as a treatment. The treatments were replicated thrice. The rooted cuttings were planted at 30 X 30 cm distance. The vigorous growth in terms of plant height (54.87 cm) was noted significantly in variety „Maghi‟ (T4) while plant spread was found significantly maximum in variety „Ratlam Selection‟ (T9) (29.63 cm) and in „Maghi‟ (T4) (40.09 cm) in North-South and East-West directions, respectively. Significantly maximum leaf size was observed in variety „Thai Chen Queen‟ (T15) (5.61 cm), in variety „Harvest‟ (T12) (4.25 cm) and in variety „Flirt‟ (T3) (3.10 cm) with respect to leaf length, leaf width and petiole length, respectively. A thorough glance of leaf area was found significantly maximum (17.50 cm2) in variety „Dolly White‟ (T13). On the subject to early flower bud initiation (63.99 days) and flower opening (71.73 days) were recorded in variety „Red-2‟ (T7). However, biggest flower (12.65 cm) and highest flower weight (9.78 g) were noted in variety „Thai Chen Queen‟ (T15). Number of ray florets per flower was found significantly maximum in variety „Maghi‟ (T4). With respect to flower duration, significantly longest duration of flower (56.67 days) was resulted in variety „Ratlam Selection‟ (T9). Consequently, yield contributing characters i.e. number of flowers (99.67 per plant and 1898.94 per plot) was found significantly maximum in variety „Maghi‟ (T4). The yield of flowers (199.33 g per plant and 4330.27 g per plot) was observed significantly highest in variety „Thai Chen Queen‟ (T15). Association between yield of flower per plot and other contributing characters revealed that yield of flowers per plot was noted highly significant and positive correlation with plant height (cm), plant spread (cm), days to bud initiation, flower diameter, number of ray florets per flower, flower weight, number of flowers per plant per plot and yield of flowers per plant at both genotypic and phenotypic levels. Whereas, significant and positive correlation was observed with leaf length and days to flowering only at genotypic level. Path coefficient analysis indicated that number of flowers per plant has highest positive direct effect on yield of flowers per plot followed by leaf area (cm2). Based on these findings, it can be suggested that for improving flower yield in chrysanthemum, more emphasis should be given to days to flowering, flower diameter, number of flowers per pant, plant height and flower weight. The results of the present investigation suggested that the chrysanthemum varieties could be effectively categorized and characterized based on morphological characters and as such, these traits could be utilized as good descriptors in the identification and maintenance of chrysanthemum varieties. This existed ample variation and diversity in chrysanthemum could be utilized for cut flower, loose flower and pot mum purpose. The varieties Ravi Kiran, Shyamal, Flirt, Neelima, Ratlam Selection and Thai Chen Queen are best suitable for cut flower purpose, whereas varieties Jaya, Pancho, Maghi can be selected for loose flower purpose because of attaining more number of flowers per plant. However, varieties Red-2, Ajina Purple, Pancho, Lalpari, Dolly White and Mayur are best suitable for pot mums.

Ajina Purple” conducted at Floriculture Research Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari (Gujarat) during the year 2016-17. The experiment was laid out in a Completely Randomized Design (CRD) with eleven treatments of different growing media and their combinations viz. Soil (T1), Soil + Sand + Vermicompost (1:2:1 v/v) (T2), Soil + Sand + Bio compost (1:2:1 v/v) (T3), Soil + Sand + Poultry manure (1:2:0.5 v/v) (T4), Soil + Sand + Vermicompost + Bio compost (1:2:1 v/v) (T5), Soil + Sand + Vermicompost + Bio compost + Poultry manure (1:2:1:1:0.5 v/v) (T6), Cocopeat + Vermicompost (2:1 v/v) (T7), Cocopeat + Bio compost (2:1 v/v) (T8), Cocopeat + Poultry manure (2:0.5 v/v) (T9), Cocopeat + Vermicompost + Bio compost (2:1:1 v/v) (T10) and Cocopeat + Vermicompost + Bio compost + Poultry manure (2:1:1:0.5 v/v) (T11). The treatments were replicated thrice. Influence of different growing media and their combinations on growth, flowering and physico-chemical properties of each medium including bulk density, field capacity, particle density, pH, EC, organic carbon, available N, P and K of growing media were studied. The vigorous growth in terms of plant height (30.87 cm), plant spread (N-S and E-W) (28.15 and 28.93 cm, respectively), number of branches per plant (16.40), Fresh weight of plant (342.80 g) and dry weight of plant (170.87 g) was noted significantly in plants grown in combined media of Cocopeat + Vermicompost + Bio compost (2: 1: 1 v/v) (T10). Consequently these plants produced early flowering (45.43 days). Maximum flower diameter (37.42 mm), longest blooming period (94.67 days) and duration of flowering (126.33 days) with highest no. of flowers (66.61) were also significantly influenced in the plant grown with the same medium. This media having good physico-chemical properties like low bulk density (0.29) and particle density (0.73), appropriate water holding capacity (330.33 %) and field capacity (198.65 %), high N (1186.86 kg/ha), P (95.67 kg/ha), K (2745.67 kg/ha) in media maximum organic carbon (22.70%), suitable EC (1.69dsm-1) and pH (6.05) as required by pot chrysanthemum. On the basis of the results obtained in present investigation, it can be concluded that Cocopeat + Vermicompost + Biocompost (2:1:1 v/v) was found best potting media for vigorous growth of plant and more number of flowers in pot chrysanthemum var.
