| 摘 要： | 通过室内砂培试验,研究低温逆境下氯化胆碱包衣玉米种子对其萌发及幼苗生理生化指标的影响。结果表明,低温逆境下氯化胆碱包衣能显著提高种子发芽率、发芽指数和活力指数,并提高种子发芽势;包衣处理明显提高低温逆境下玉米幼苗的苗高、根长、茎粗、根冠比和单株干重,具有良好的壮苗作用;低温逆境下包衣处理的幼苗叶片叶绿素含量和脯氨酸含量均高于对照,丙二醛含量和相对电导率低于对照。

| Abstract: | Effects of choline chloride seed-coating on seed germination and the physiological and biochemical guideline of seedling in maize were investgated under low temperature stress through sand culture method. The results indicated that the germination percent-age, germination index and vigor index of maize with choline chloride seed-coating under low temperature stress were significantly higher than those of the uncoated controls, but the germination energy was a few higher than contrast. And the treatment with choline chloride seed-coating could significantly improve the control of seedling height, root length, stem diameter, dry weight per plant and the root-cap ratio. So it could help the strong seedling well. After low temperature stress, the chlorophyll content and proline about choline chloride seed-coating were all higher than contrast, the malondialdehyde (MDA) content and relative conductivity were lower than contrast. |
