Abstract

Coriander (Coriandrum sativum L.), an annual herb, experiences rapid seed quality decline during storage, affecting crop vigor and establishment. With a minimum germination requirement of 60%, seed priming becomes crucial for enhancing germination and crop stand. The current study focused on standardizing the priming period for the DW-3 coriander variety. Under a Completely Randomized Design, the experiment involved 21 treatments with varied durations (4, 8, 12, 16, and 20 hours) of priming using hydropriming, vermiwash (5%), nano-urea (5%), GA3 at 50 ppm, and a control. Regardless of medium or concentration, GA3 priming for 12 hours resulted in significantly higher germination (80.33%), shoot length (17.47 cm), root length (15.30 cm), seedling length (32.77 cm), and seedling vigour index (26.32) compared to the control. This study highlights the critical impact of priming duration and seed treatment on coriander seed yield and quality, emphasizing the need for optimal priming durations and effective seed treatment techniques in coriander cultivation.

Conclusion

The investigation into the standardization of seed priming durations in coriander unveiled notable disparities in seed quality parameters resulting from diverse seed priming treatments. Specifically, the seed priming treatment involving GA3 at 50 ppm for a duration of 12 hours (denoted as T19) exhibited superior outcomes across various metrics, including germination rate, speed of germination, root length, shoot length, seedling vigor index-I, seedling dry weight, seedling vigor indices, field emergence, and displayed the lowest seed infection percentage. These findings emphasize the significant efficacy of 12-hour GA3 priming in enhancing coriander seed quality, suggesting promising implications for improving crop establishment and early-stage growth.
