Effect of seed priming treatment with salicylic acid on viability of okra (Abelmoschus esculentus L.)‎ seeds

الملخص EN

The present study was conducted to knowledge the effect of seed priming techniques on seeds viability characteristics of okra seeds, an experiment was conducted at the seeds obtained directly from the okra field of Babil governorate during the season of (2012).

Seeds were soaked for 4 hours at 25 Cº in priming media (10, 25, 50, 75 & 100 mg\L of salicylic acid, hydropriming, distilled water and unprimed seeds as control).

Maximum seed germination percentage, germination speed index (GSI) and seedling vigour index (SVI), were observed when the seeds primed by 100 mg\L salicylic acid for 4h at 25 Cº.

Relative growth rate and all seeds germination characteristics in this study also increased with increasing salicylic acid concentration from 10 to 100 mg\L compared with control treatment.
