Coriander (Coriandrum sativum l.) seed quality as affected by accelerated aging and subsequent hydropriming

Hydropriming is one of the seed germination enhancing techniques which is simple, safe, nonchemical and harmless to the environment. The aim of the present study was to investigate the effect of hydropriming on the germination and vigor of aged coriander (Coriandrum sativum L.) seeds. Seeds were aged at 42°C and 100% relative humidity for 0, 24, 48, 72 and 96 h and then primed by soaking in distilled water for 8 h and incubated at 20°C for 24 h, compared to non-primed seeds as control. Results obtained showed that primed seeds resulted in earlier germination and higher first count, germination percentage than those of non-primed seeds, irrespective of aging duration. Seeds aged for 0, 24 and 48 h with subsequent priming or nonpriming showed high germination percentages but these were not significant difference among treatments. Increased aging duration to 72 h resulted in decreased germination percentages and primed seeds revealed higher germination percentages than those of non-primed seeds. However, the lowest germination percentage occurred in 96 h aged seeds, with priming or nonpriming.
