Effect of seed priming on germination indices of Flixweed (Descurainia Sophia L.) in drought condition
Journal Title: International Journal of Farming and Allied Sciences - Year 2017, Vol 6, Issue 3
Abstract
Seed priming is a method that can be used to advance germination and growth in stressful conditions. In this study we investigated the effect of seed priming with gibberellic acid in two concentration (25ppm and 50ppm), KCl (0.5 M) and CaCl2 (0.5 M) in drought stress condition on Flixweed (Descurainia Sophia L.) seeds. An experiment was carried out using factorial experiment in randomize complete design with three replications. Germination indices including final germination percentage (FGP), the coefficient of velocity of germination (CVG), Germination rate index (GRI), the mean germination time (MGT), Germination speed (GS) and the mean of daily germination (MDG). Results of this experiment indicate that drought stress reduced all germination indices. In non-stressed conditions GA3 treatment has improved germination index and GA3:50ppm was better than GA3:25ppm. In stressful conditions CaCl2 treatment has better effect than other treatments and also GA3:50ppm was in second level. According to our results the effect of KCL was not significant and this treatment could not improve germination indices.
