盐水选种对苤蓝种子活力的影响

通过在不同浓度盐水中浸种不同时间选种,研究了不同选种方式对苤蓝种子活力的影响。试验结果表明,以0.4%的盐水浸泡1.5 h的处理选出的种子发芽指数、活力指数均最高,而发芽率和发芽势仅比最高值低0.25个百分点和2.7个百分点,差异不明显。因此,综合考虑在生产中用0.4%的盐水选种1.5 h可达到提高苤蓝种子活力的目的。

Effects of Seed Sorting by Using Salt Water on Kohlrabi Seed Vigor

We studied the effects of soaking seeds in salt water with different concentrations for different times on the vigor of kohrabi seeds. The results showed that, soaking in 0.4% salt water for 1.5 hours, the seeds had the highest germination index, vigor index, and the germination rate and germination potential were only 0.25% and 2.7% lower than those of the corresponding maximum value respectively, while the differences were not significant. Therefore, soaking in 0.4%salt water for 1.5 hours was best for improving the seed vigor of kohrabi in production.
