ThesisItem Open Access Seed source variation in Medicinal Tree- Aegle marmelos (L.) Correa (Bael)(Forest Product and Utilization Dept., ACHF, NAU, Navsari, 2016-06) DAMOR, VIPULKUMAR V.; Desai, B.S.The present research work entitled “Seed source variation in Medicinal Tree- Aegle marmelos (L.) Correa (Bael)” The study was carried out at the Model Nursery on Medicinal and Aromatic plants Nursery, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat (AES-III, South Gujarat Heavy Rainfall Zone), during July-2012 to February-2013. The results are summarized in this chapter. The highest fruits length (8.62cm) was recorded from fruit collected from Shamlaji; whereas, the minimum fruit length was recorded from Waghai (5.55 cm) seed source. Maximum fruit diameter (6.56 cm) was recorded from fruit collected from Navsari (South Gujarat region) and minimum fruit diameter (6.00 cm) was recorded in Gandhinagar (middle Gujarat region). The highest seed length (0.83 cm) and seed width (0.39 cm)was observed in the seed collected from Junagadh; the minimum value of seed length (0.50 cm) and seed diameter (0.23 cm) was recorded from Shamlaji seed source. The maximum value of seed weight (17.87 g) was recorded in Junagadh whereas the minimum value of 100 seed weight (g) (14.46 g) was observed in Shamlaji seed source preceded by Danta seed source i.e. 15.16 g. The data revealed that maximum germination percentage (28.36 %) was recorded in Vijaynagar and highest survival percentage (25.99 %) was observed in Rajpipla seed source. Whereas, minimum germination percentage (17.81 %) and survival percentage (16.33 %) was recorded in Navsari seed source. The maximum shoot length (18.92 cm) was recorded for Ratanmahal; whereas the minimum shoot length was recorded from Danta seed source i.e. 14.51 cm. The maximum collar diameter (3.81 mm) was recorded in Junagadh while minimum collar diameter (2.62 mm) was recorded in Shamlaji seed source. The highest no. of leaves were observed in Gandhinagar (10.97); whereas, lowest no. of leaves were recorded in Shamlaji (4.27). The maximum root length (54.87 cm) was recorded in Junagadh and the minimum root length (17.97 cm) was recorded in Ratanmahal seed source. However, the maximum root diameter was observed in Rajpipla (5.57 mm) and minimum root diameter (2.74 mm) was observed in Danta seed source. The highest fresh weight of seedling was recorded in Junagadh (6.64 g) while lowest fresh weight (2.53 g) of seedling was observed in Danta seed source. However, the maximum dry weight of seedling (2.22 g) was observed in Waghai and minimum dry weight of seedling (0.84 g) was recorded in Vijaynagar seed source. Wide differences have been recorded for the coefficient of variation and genetic parameters for fruit, seed, germination, growth and biomass charaters of Aegle marmelos. For all the characters, the phenotypic (PCV) and genotypic (GCV) coefficient of variability were found to be higher than the corresponding environmental coefficient of variability (ECV). Among fruit and seed characters, the PCV and GCV were maximum for seed width (20.01 and 17.78, respectively). Higher heritability for fruit length (0.93) followed by seed width (0.79) was observed. Genetic gain was also recorded maximum for seed width (32.43 %) followed by fruit length (26.24%). Among germination survival growth and biomass characters, the phenotypic coefficient of variation and genotypic coefficient of variation were maximum for root length (39.54 and 37.52, respectively). ECV was maximum for fresh seedling biomass (19.72). Maximum heritability (0.90) observed in root length, closely followed by root diameter (0.85). Genetic gain was also maximum in root length (73.33 %), while it was minimum for shoot length at five months (5.85 %).ThesisItem Open Access CREENING OF CYMBOPOGON SPP. AND OCIMUM SPP. FOR DEVELOPMENT OF TEAK BASED SILVI-MEDICINAL SYSTEMS IN SOUTH GUJARAT(FORESTRY DEPT., ASPEE COLLEGE OF HORTICULTURE AND FORESTRY, NAVSARI AGRICULTURAL UNIVERSITY, NAVSARI, 2014-07) MUKESH KUMAR; Thakur, N.S.The present investigation was carried out at the Experimental Farm, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari in 2013 -14. Two experiments were conducted simultaneously. In first experiment, three Ocimum species i.e. O. tenuiflorum (O 1 ), O. gratissimum (O 2 ) and O. basilicum (O 3 ) were cultivated under 18 year old Teak based silvi-medicinal syste m (LU 2 ) and sole cropping (LU 1 ) syste m as intercrops, whereas in second experiment three Cymbopogon species i.e. C. citratus (C 1 ), C. pendulus var. CKP 25 (C 2 ) and C. martini (C 3 ) were taken as intercrops. Factorial Rando mized Block Design (2 x 3) with four replications was used to analyze the data. In first experiment, significantly higher plant height, number of branches, leaves per plant, plant spread and specific leaf weight, fresh as well as dry above and below ground and total herbage (panchang) yield, essential oil yield of Ocimum species were recorded under sole cropping syste m as co mpared to silvi -medicinal syste ms, whe reas 4 chlorophyll content index and leaf nitrogen content were recorded significantly higher under silvi -medicinal system as compared to sole cropping system. However, leaf area and oil recovery did not bear any significant difference between two land use s ystem (teak based silvi-medicinal syste m and sole cropping system). Out of three Ocimum species, maximum plant height, number of branches, leaves per plant and plant spread were recorded for O. tenuiflorum. Whereas, maximum leaf area and specific leaf weig ht, higher fresh and dry above ground and total herbage yield, higher essential oil recovery and oil yield, higher chlorophyll content index and leaf nitrogen content were recorded for O. gratissimum. Among intercrops, O. gratissimum accrued highest net re turns and BCR fro m herbage (Panchang) and O. tenuiflorum accrued highest net returns and BCR fro m essential oil irrespective of land use systems. The higher value addition realized due to difference in net returns fro m essential oil and panchang per hectar e was accrued fro m O. tenuiflorum and O. basilicum. In second experiment, two species ( Cymbopogon pendulus var. CKP 25, C. martini) were failed, only C. citratus survived. Higher number of tillers, specific leaf weight and plant spread, tota l fresh as well as dry herbage yield, essential oil recovery and oil yield of Cymbopogon citratus were recorded under sole cropping system as compare to silvi- medicinal syste ms. However, height and leaf area, leaf nitrogen content and chlorophyll content index were recorded maximum under silvi-medicinal system as co mpare to sole cropping syste m. C. citratus accrued highest net returns and BCR fro m herbage and essential oil under sole cropping syste m, respectively.
