tailieunhanh - Influence of pre-sowing seed treatment and growing conditions on growth performance of Indian gooseberry seedlings (Emblica officinalis Gaertn)

The study was carried out at Fruit Research Station, Imaliya, Department of Horticulture, college of Agriculture, JNKVV, Jabalpur, (.) during January 2018 to May 2018. The experiment consist of three growing conditions viz. (C1) Open condition, (C2) net house, (C3) poly house condition and six treatments of seed . (S1) water soaking, (S2) GA3 200 ppm, (S3) GA3 400ppm, (S4) GA3 600ppm, (S5) Thiourea , and (S6) Thiourea 1% having 18 treatment combinations. Among the growing conditions poly house and among the seed treatment, GA3 (600ppm) were proved most promising as compare to others. Among the various treatment combinations, the C3S4 treatment combination (poly house and 600 ppm GA3) was proved most superior over rest of the treatment combinations with respect to growth parameters and Physiological Parameters like height of shoots ( cm), number of leaves per seedling (), girth of stem ( mm) at 120 DAS respectively. However, the fresh weight of shoots ( g), dry weight of shoots ( g), fresh weight of roots ( g), dry weight of roots () Seedling vigour index I ( cm), Seedling vigour index II ( g), Leaf Area Index (), Leaf Area Duration ( cm2 .day), Light transmission ratio () and Energy Interception (), recorded at 120 DAS were found to maximum in C3S4 treatment combination. | Influence of pre-sowing seed treatment and growing conditions on growth performance of Indian gooseberry seedlings (Emblica officinalis Gaertn)
