摘要:
研究在实验室条件下不同温度，不同光照和不同土壤含水量对大豆胞囊线虫（SCN）休眠卵孵化的影响。分别测定了5个温度梯度下（18℃、21℃、24℃、27℃和30℃），7个光照条件下（0/24 h，4/20 h，8/16 h，12/12 h，16/8 h，20/4 h和24/0 h）和7个土壤含水量（1%、5%、10%、15%、20%、25%和30%）条件下SCN休眠卵的孵化情况。结果表明：在供试温度18~30℃之间，休眠卵的孵化总量随温度升高而增加，30℃下孵化数量最大，达1316.33条。全光照处理的孵化量最大，达745.00条，4L/20D、12L/12D和20L/4D次之，而全黑暗处理的孵化量最少，仅为102-00条。土壤含水量在1%~30%之间，含水量为15%时孵化数量最大，达265.33，含水量在1%~15%时，孵化量随含水量的增加而增加，当含水量大于15%时，孵化量随含水量增加反而降低。研究证实在SCN休眠期可以通过提高温度增加光照时间来诱导卵孵化，以提高J2孵化数量，采用休眠胞囊接种应注意调节土壤含水量。
Abstract:
The effects of temperature，illumination and soil water content on dormant eggs of Heterodera glycine were studied in lab.Hatching of the eggs were assayed under 5 tested temperatue(18℃，21℃，24℃，27℃ and 30℃)，7 tested illumination conditions(0/24 h，4/20 h，8/16 h，12/12 h，16/8 h，20/4 h and 24/0 h)and 7 kinds of soil water contents(1%，5%，10%，15%，20%，25% and 30%)，respectively.Total number of hatched J2 increased with increasing of temperature among 18-30℃，and reached 1316.33 under condition of 30℃.Amount of hatched J2 of full illumination treatment reached 745.00，followed by treatments of 4L/20D，12L/12D and 20L/4D，and that of full dark treatment was the least.Among all water content treatments，hatched J2 reached the most under 15% water content，however the amount of hatched J2 reduced when tested water content over 15%.It is concluded that eggs hatching can be induced by high temperature and long illumination，while regulating soil water content is necessary to inoculation with dormant cysts to soybean.
