种子引发对辣椒和茄子种子在不同温度下萌发和出苗的影响
Effects of seed priming on seed germination and emergence of pepper and eggplant at different temperature
摘要
Abstract
The effects of solid matrix priming with vermiculite or osmopriming with KNO3 on seed germination and emergence of pepper and eggplant at different temperature were studied in the paper.The results showed that priming improved seed germination and emergence of pepper and eggplant at different temperature.The lower the temperature,the more significant the effect was.Compared with control,solid matrix priming with vermiculite significantly improved seed germination vigor of pepper and eggplant 53.3％-82.0％,germination index 3.1-6.8,vitality index 0.1-0.3,emergence percentage 25.7％-57.1％,seedling emergence index 0.8-2.3,fresh weight of seedling 0.80-0.89 g and the average seedling emergence time was advanced 2.9-4.9 d at 20℃ day/15℃ night.Osmopriming with KNO3 significantly improved seed emergence percentage of pepper and eggplant 5.7％-17.1％.Effect of solid matrix priming with vermiculite was better than that of osmopriming with KNO3.关键词
