Abstract

Lacticaseibacillus paracasei, as a biopriming agent, and hydropriming were used to evaluate their impact on the seedling vigor of eggplant (Cleopatra F1).  Different priming periods (0.5, 3.5, 6.5, and 9.5 h) were used, whereas unprimed seeds served as the control. Seeds were arranged in a Completely Randomized Design with four replications. Ambient conditions (temperature: 30 ± 2 °Cand relative humidity: 65 ± 5%) of the Postharvest and Seed Technology were used. Results showed that hydropriming and biopriming had different effects on seed and seedling vigor parameters. A 3.5 h of hydropriming was enough to produce more than 85% germination percentage compared to biopriming. Hydropriming for 9.5 h improved the germination index as compared to unprimed and biopriming, except for 9.5 h. The former showed a similar germination index to the other priming periods. Faster germination was observed in 6.5 h of hydropriming than without priming. Hydropriming (9.5 h) and biopriming (0.5 h) induced root elongation. However, shoot elongation was stimulated by biopriming at 0.5 h. Biopriming at 0.5 h produced longer seedlings than the hydroprimed and unprimed seeds. But vigorous seedlings were observed in seeds with 3.5 h of hydropriming. Based on the results, hydropriming using 3.5 h can be used to produce vigorous seedlings.
