- 摘要:
- 以萝卜品种“洛育201”种子为试材，采用不同浓度（0、5、10、20、30、40 mg?L-1）的赤霉素（GA3）对萝卜种子及幼苗进行处理，研究了GA3对萝卜种子发芽率及幼苗生长的影响。结果表明：不同浓度GA3可以促进萝卜种子萌发，能够显著提高萝卜幼苗根长、根系活力、株高，叶绿素、可溶性蛋白质含量，可显著降低丙二醛含量。GA3浓度为20 mg?L-1时对萝卜种子萌发的促进作用最大，GA3浓度为10 mg?L-1时对萝卜幼苗生长的促进作用最大。
- Abstract:
- Taking ‘Luoyu 201’radish seed as material，radish seeds were treated with different concentration (0 mg/L，5 mg?L-1，10 mg?L-1，20 mg?L-1，30 mg?L-1，40 mg?L-1) of GA3.The effect of GA3 on germination and seedling growth of radish was studied.The results showed that the germination of radish seed and the growth of seedling were significantly promoted after the seeds treated with GA3.The root length，root activity，plant height，the chlorophyll content and soluble protein content of the radish seedlings were increased，while the content of MDA was decreased.The best GA3 concentration was 20 mg?L-1 for seed germination，and was 10 mg?L-1 for seedlings.
