Rice root--knot nematode (Meloidogyne oryzae Feng, 1975 ) is a new disease of rice, which was first recorded by our laboratory in 19T3 in China, A study on the influence of the root-knot nematode on rice growth was carried out over the years 1973-1975. The influence was found to be significant. The characteristic symptoms of the disease are an enlargement of and the formation of knot on the rice roots. In the seedling stage, the growth of the root tips was retarded, the plant being week. After transplanting,...

Rice root--knot nematode (Meloidogyne oryzae Feng, 1975 ) is a new disease of rice, which was first recorded by our laboratory in 19T3 in China, A study on the influence of the root-knot nematode on rice growth was carried out over the years 1973-1975. The influence was found to be significant. The characteristic symptoms of the disease are an enlargement of and the formation of knot on the rice roots. In the seedling stage, the growth of the root tips was retarded, the plant being week. After transplanting, the diseased plants were stunted, lacking vigour. Some of them failed to continue to grow, with death rats higher than those of the healthy ones. During the tillering stage, the symptoms on the above ground parts are visible on the foliage; the tillering ability and rate- of tillering were reduced, the leaves turned yellowish, and growth retarded. In the heading stage, the heading period was shortened, the ear small and yields, reduced. Applicataon of nematicides ( DBCP ) resulted in an increase of yields of 10-20% ( in the moderate diseased fields ).The resulted were apparently different from those of Hollis et al. ( 1966 ) . The difference was found to be due to the different species of nematodes involved.

水稻根结线虫病是我国一种新发现的水稻病害。1973~1975年,我们对此线虫病进行研究。实验表明:此病对水稻的生长发育和产量的影响是明显的。在水稻幼苗期病苗纤弱,叶色稍谈。移植后返青慢,发根迟,死苗多。分蘖期地上部症状较显著,一般株矮,根短,分蘖迟缓,分蘖力弱,生势衰弱;但园稈拔节都比健株发生要早。在出穗和结实期,病株出穗期短,出稳数少,同时穗小,粒少,结实率低。在一般中等发病情况下,影响产量在10-20%左右;严重发病时可达40-50%,是目前我国水稻生产上一个值得注意的问题。但国外报道认为此类线虫病对水稻的影响是轻微的和暂时的,与我们的实验结果有较大的出入。探究其原因,主要是由于病原线虫种类不同所引起。目前在我国水稻上发现的根结线虫为一新种,鉴定结果将另文发表。

Root-knot of cucumbers is a common and quite severe disease in Nanjing,Jiangsu Province. The diseased cucumber plants grow not well and wilt prematurely. Typical nematode root-knot can be found under examination. The causal organism is identified as Meloidogyne incognita Chitwood.

During April 1980-June 1982, fifty root samples of tea seedlings infected with root-knot nematode were collected from Hangzhou, Jinghua, Yuhang, Fuyang, Shauxing, Zhenhai, Jiaojiang, Lexing, Xuzhou and Shongyang in Zhejiang Province. The criterion for identification of Meloidogyne species based on the characteristics of perineal pattern of the adult female and the head shape and style, morphology of the male. Four species, ie, Meloidogyne arenaria, M. incognita, M. javanica and M. thamesi have been identified....

During April 1980-June 1982, fifty root samples of tea seedlings infected with root-knot nematode were collected from Hangzhou, Jinghua, Yuhang, Fuyang, Shauxing, Zhenhai, Jiaojiang, Lexing, Xuzhou and Shongyang in Zhejiang Province. The criterion for identification of Meloidogyne species based on the characteristics of perineal pattern of the adult female and the head shape and style, morphology of the male. Four species, ie, Meloidogyne arenaria, M. incognita, M. javanica and M. thamesi have been identified. The frequency of tea seedling roots infected with M. arenaria and M. incognita was greater than that infected with M.javanica and M.thamesi.

作者自1980年4月至1982年6月分别从浙江省杭州、金华、余杭、富阳、绍兴、镇海、椒江、乐清、衢州、松阳等10县(市)采集到茶苗根结线虫病(Meloidogyne.spp)病株和病苗样本共50号。根据雌虫的会阴花纹特征和雄虫头部、口针的形态学,初步鉴定病原线虫为下列4个种:花生根结线虫(M.arenaria)、南方根结线虫(M.incognita)、爪哇根结线虫(M.javanica)及泰晤士根结线虫(M.thamesi)。其中以花生根结线虫和南方根结线虫出现的频率较高。
