| 摘 要： | 1958-1980年,作者采用镜检、活点观察、复水、染色、盆栽及田间接种等同步比较方法研究证明,干荚果虫瘿内的病原线虫态已全部死亡,干荚果不是此病的传播途径,迄今分布如此广泛,认为是"自然疫源"所致。试验指出,荚果含水量的多少,是致死虫瘿内线虫的主要因素,荚果含水量在26.11%以下,虫瘿内线虫全部失去侵染力,荚果的安全贮藏含水量是在10%以下,一般8%左右,所以,病原各虫态更不能存活。该病原的致命弱点不抗干燥。

| Abstract: | From 1958 to 1980, results of studies on the peanut root-knot nematode indicated that all stages of nematodes in the dry pods were dead, and there-fore the dry pods were not the spreading source of this disease.The experiment showed that the water content in the pods was the main fact or for the longevity of the gall.Nematodes in gall lost their infectivity if the podwater-content was below 26.11%.All stages of nematodes were not able to live any longer if the pod-water-content was below 10%. |
