Abstract:
An experiment was conducted to assess the effect of different seed priming treatments and growing conditions on seed germination and seedling vigour of Aonla. The experiment was carried out at College of Horticulture, Venkataramannagudem during January 2022 to May 2022 in Factorial Randomised Block Design with 3 replications comprising 16 treatment combinations. Seeds of Aonla were treated with GA₃ at different concentrations of 300, 500 and 700 ppm at different soaking period of 12 and 24 h under shade net and poly house conditions, along with water soaking for 24 h. The experiment results indicated that the combination of seed priming and growing condition with GA₃ @ 500 ppm for 24 hours + poly house recorded minimum number of days to germinate (7.93), maximum germination percentage (81.30%), height of seedling (53.67 cm), vigour index I (4,351.0), vigour index II (1003), chlorophyll content (54.16) and survival percentage (89.32%).
