Effect of salicylic acid on germination performance in groundnut.

ABSTRACT

The present investigation has been carried out on the influence of various concentrations of salicylic acid (SA) on the germination performance of groundnut seeds of cv. W-55, W-44, TAG and SB-11. The groundnut cultivars W-44, TAG and SB-11 showed significant germination by SA application over control. In cv. W-55 all the imposed SA concentrations increased germination except 10 ppm SA particularly after 48 hrs of germination. In general Salicylic acid with 50 ppm concentration showed significant germination in all groundnut cultivars. SA also showed positive impact on root and shoot growth in W-44, TAG and SB-11 cultivars whereas opposite trend was noticed in W-55. These findings clearly indicated that the cv. SB-11 was the best performer to salicylic acid among the studied cultivars of groundnut.
