    INFLUENCE OF DIFFERENT GROWING MEDIA ON GROWTH AND FLOWERING OF CHRYSANTHEMUM (Dendranthema grandiflora) CULTIVARS FOR POT MUMS
    (Sri Konda Laxman Telangana State Horticulture University, Mulugu, Siddipet (Dist.), College of Horticulture, Rajendranagar, Hyderabad-30, 2019-07-16) P. MAMATHA; Dr. A. Manohar Rao
    The present investigation entitled “Influence of different growing media on growth and flowering of chrysanthemum (Dendranthema grandiflora) cultivars for potmums” was carried out at Floricultural Research Station, Sri Konda Laxman Telangana State Horticultural University, Hyderabad during September 2018 to February 2019. The experiment was conducted in factorial completely randomized design comprising 18 treatment combinations with 3 replications. The treatments consisted of 9 growing media G1: soil + sand + FYM (2:1:1), G2 : soil + sand + vermicompost (2:1:1), G3: cocopeat + sand + FYM (2:1:1), G4:cocopeat + sand + vermicompost (2:1:1), G5: soil + cocopeat + sand + FYM (2:1:0.5:0.5), G6: soil + cocopeat + sand + vermicompost(2:1:0.5:0.5), G7:cocopeat + soil + sand + FYM (2:1:0.5:0.5), G8: cocopeat + soil + sand + vermicompost (2:1:0.5:0.5), G9: control ( red soil ) with two cultivars Cv. Akitha and Cv. Redstone. The growth parameters at 30, 60 and 90 days after planting, flowering, flower quality parameters were recorded and subjected to data analysis. Among different growing media G8 recorded maximum plant height (20.77, 24.03 and 28.40 cm), number of branches (3.10, 4.50 and 6.90), plant spread in N-S (13.51, 19.83 and 23.42 cm), plant spread E-W(14.04, 22.85 and 25.96 cm) at 30, 60 and 90 days after planting respectively, maximum number of fully opened flowers per pot(30.25), number of flowers per pot (49.40), maximum flower diameter(4.30) , flower longevity (17.97 days )and duration of flowering (26.62 days) but G7 recorded minimum number of days for flower bud initiation (59.37), 50 percent flowering (103.14) and 100 percent flowering (118.71). Among the treatment combinations C2G8 i.e. Cv. Redstone in cocopeat + Soil + Sand + vermicompost (2:1:0.5:0.5) recorded maximum plant height (19.93, 24.33 and 30.73 cm), number of branches (3.53, 5.07and 7.20), plant spread in N-S (14.83, 20.49 and 24.18cm), plant spread E-W(15.00, 24.03 and 28.32 cm) at 30, 60 and 90 days after planting respectively, maximum number of fully opened flowers per pot (32.17), number of flowers per pot (50.72), maximum flower diameter(4.56 cm) , flower longevity (18.73 days )and duration of flowering (27.80 days) but C2G7 i.e. Cv. Redstone in cocopeat + soil + sand + FYM (2:1:0.5:0.5), treatment combination recorded minimum number of days for flower bud initiation (49.13days ), 50 percent flowering(90.67 days) and 100 percent flowering (108.48 days). The data on economics revealed that the treatment combination C2G8 i.e. Cv. Redstone in cocopeat + Soil + Sand + vermicompost (2:1:0.5:0.5) recorded highest benefit cost ratio (4.63:1) followed by C2G7 i.e. Cv. Redstone in cocopeat + soil + sand + FYM (2:1:0.5:0.5) (4.56:1) when compared to all other treatment combination. It can be concluded from present investigation that among two cultivars Cv. Redstone responded well when compared to Cv. Akitha. The growing media G8: cocopeat + soil + sand + vermicompost (2:1:0.5:0.5) had shown significant difference in growth, flowering and flower quality attributes with highest benefit cost ratio among all other growing media.

    STUDIES ON THE EFFECT OF PRETREATMENTS AND PACKAGING MATERIALS ON QUALITY ATTRIBUTES OF GRAPE POMACE
    (College of Horticulture, Rajendranagar, HYD-30, 2016-08-06) P. MAMATHA; Dr. K. VANAJALATHA
    Grape (Vitis vinifera L), basically temperate crop which has got adapted to sub-tropical climate of peninsular India belongs to the family Vitaceae and one of the most important commercial fruit crops of India. In India, Grape occupies 1.6% of total fruit area, 2.9% of total fruit production and grown in an area of 118.7 thousand hectares with a total production of 2585.3 thousand MT and productivity of 21.8 MT/ha (NHB 2015-16 data base). In India, Maharashtra is the leading state in grape production and Telangana accounts for only 1 per cent of total production. Grape is rich source of phenolic and fiber compounds and intake of grape products such as juice or wine have recognized health benefits (Xia et al, 2010). About 80% of the world production is utilized for wine making, 10% for table purpose and the balance 10% for raisin and juice purpose. Among grape processing industries, the wine industry produces million tons of left-over followed by juice industries that represent an ecological and economical waste management issue. About 20% of the weight of processed grapes remains as grape pomace (Pomace is the general term for any solid material such as the skins, pulp and seeds leftover after wine or juice extraction). Unlike grape flesh, grape skin and seeds are the potential source of antioxidant and anticarcinogenic phenolic compounds (Cantos et al, 2002) and also contains concentrated pro-anthocyanidins, carotenoids, xanthophylls, anthocyanins, tannins etc. Grape pomace is a good source of polyphenols containing approximately 40% fiber, 16% oil, 11% proteins and 7% complex phenols, sugars, mineral and salts etc (kim et al, 2006). Recovery of phenols and fibre from grape pomace has attracted increasing attention in the past years, and industries are finding high value and sustainable alternative to the residues. Grape pomace is a potential source of phytochemicals that may be recovered as functional compounds for the pharmaceutical, cosmetic, food industries and as biopesticides (Fontana et al, 2013). It is also known that polyphenols have health-promoting effects and anti-aging properties (Fontana et al, 2013) there by prevent risk factors related to metabolic syndrome and several chronic diseases in aging humans (Galleano et al, 2012). These biological properties of polyphenols are attributed mainly to their powerful antioxidant, metal chelating and antiradical activities.
