The Effect of Exogenous Application of GA3 to Mitigate the Salt Induced Damages in Rice Cultivars during Germination
Year: 2018
Type: article
Abstract: In the present study the two paddy cultivars were selected to examine the effect of salinity, GA 3 and the effect of GA 3 on the salinity stressed seeds, the tests were conducted at different concentrations.The salinity decreased the germination percentage, vigour index and seedling length and chlorophyll content.GA 3 , combination of GA 3 and NaCl treated seeds showed increased germination percentage in both the cultivars, but the decrease in germination percentage due to salinity was more in Jyothi cultivar compared to the BPT Super cultivar.GA 3 played the salinity attenuating role, Jyothi cultivars seems to be more salt sensitive when compared to the BPT Super cultivar.The Chlorophyll a, Chlorophyll b and total chlorophyll content was decreased in salinity in both the varieties, but a gradual increase was found in GA 3 treatment and also combination of NaCl and GA 3 treatments .The decrease in chlorophyll content under salinity was more in Jyothi cultivar when compared to the BPT Super cultivar.
