【摘要】 |
|
The effects of incorporation SA into KNO3 priming solution on the germination and emergence of eggplant seeds at 15°C were investigated. Seeds were primed into 3% KNO3 containing 0.05, 0.1, 0.5, or 1？mM salicylic acid (SA) for 6 days, respectively. After the priming, seeds were either immediately used for germination and emergence test at 15°C or stored at 4°C for 1 month and then for the germination test. The primed eggplant seeds in general improved the final germination percentage (FGP), germination rate (G50), and germination synchrony (E10–90) at 15°C compared with non-priming seeds. Priming seeds in 3% KNO3 solution supplement with 0.1？mM SA resulted in the best priming effect compared with other priming treatments and non-priming treatment, and all of the beneficial priming effects were still retained after stored at 4°C for 30 days. These results indicated that priming seeds in 3% KNO3 solution containing 0.1？mM SA could be used as an effective method to improve low-temperature performance of eggplant seeds and subsequent seedling growth. |
