Abstract:

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(0/24h,4/20h,8/16h,12/12h,16/8h,20/4h和24/0h)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。
