| 摘 要： | 以一批小麦、玉米、水稻为试验材料,进行不同离心处理,研究其对小麦、玉米和水稻种子发芽势、发芽率、根长以及苗长和苗重的影响。结果表明:不同离心处理对小麦玉米水稻种子的发芽势和发芽率有影响,其中以3000r/min离心10～15min促进效果最为显著。发芽7d后的根长、根重、苗长和苗重以3000r/min离心15min处理最好。

| Abstract: | 10 centrifugal treatments were conducted on maize rice and wheat to test centrifugal effect on Seed.Germination potential,germination percentage,root length,seedling length,seedling weight were measured at 7 days after germination.The results showed that different centrifugal treatments had remarkable promotion effect on germination potential and germination percentage.There was the biggest promotion on germination potential and germination percentage with 3000r/min for 10～15 minutes.The results also showed that 3000r /min for 15 minutes treatment was the best to root length,seedling length,seedling weight at 7 days after germination. |
