Penicillin和Ca^(2+)对玉米老化种子发芽及幼苗生长的影响

Effect of CaCl_2 and penicillin on Germination of Aged Corn Seed and Growth of Seedling

用不同浓度的CaCl2和Penicillin及二者复配后对老化的玉米种子进行处理。结果表明,Peni-cillin100m g/L、CaCl20.015mg/L、二者复配以0.015mg/LCaCl2+100mg/L Penicillin能明显提高老化玉米种子发芽率、幼苗根系活力和叶片叶绿素含量,能适当降低其种子浸泡液的电导度,并经方差分析差异达到显著水平。

Aged corn seeds were treated with different combination of CaCl2 and penicillin. The results showed that 100 mg/L of penicillin, 0.015 mg/L of CaCl2, 100 mg/L of penicillin ＋0.015 mg/L of CaCl2 increased germination percentage of aged corn seeds, chlorophyll of leaves and the vigor of root system. The electro-conductivity of the solution soaked seed decreased.
