The formerly reported virus-tolerance inducer NS-83 has been further studied at this laboratory as well as in fields. It has been revealed that NS-83 is not only a virus-tolerance inducer, but also, to a certain extent, a virus-resistance inducer. So far us tested on detached Xanthi-nc tobacco, the NS-83 treated TMV in vitro reduced 65.1%-84.8% of the lesions produced. It was also effective on the inhibition of primary infection that a spray of NS-83 on the leaves of living tobacco plants 24 hr and 48 hr before...

The formerly reported virus-tolerance inducer NS-83 has been further studied at this laboratory as well as in fields. It has been revealed that NS-83 is not only a virus-tolerance inducer, but also, to a certain extent, a virus-resistance inducer. So far us tested on detached Xanthi-nc tobacco, the NS-83 treated TMV in vitro reduced 65.1%-84.8% of the lesions produced. It was also effective on the inhibition of primary infection that a spray of NS-83 on the leaves of living tobacco plants 24 hr and 48 hr before inoculation of TMV, the reduction of lesion numbers was 73.9% and 68.3% respectively. After a solution of the F. I. fraction of NS-83 had been absorbed by the tobacco roots for 24 hr, TMV was inoculated onto the upper leaves of beth the treated and non-treated tobacco plants. The number of lesions produced on treated plants was reduced to 60.4% of the control. In field tests, the plants were sprayed with the preparation of NS-83 (with a concentration 1 /100), once at seedling bed stage and another at the time shortly after planting. The results showed that 22.9%-67.6% of the disease incidence were reduced for chilli pepper, 35.6% for tobacco, and 33.3%-73.9% for tomato in fields in different local cities. On the basis of the disease index estimated in the fields for tomato, chilli pepper and tobacco plants so far sprayed with NS-83, the therapeutic effects of the resistance inducer on the TMV infection were 82.4%, 26.3% and 83.3% respectively. Furthermore, it was observed that the occurrence of the TMV infection peak on tobacco plants was delayed 20 days in comparison with that of the non-sprayed plots. Results of biochemical analysis revealed that when the tomato plants were sprayed with NS-83, 49.8% increase of endogenous cytokinins was detected in the plant extracts, while the peak increase of peroxidases happened one week after inoculation, just at the time of acceleration of virus multiplication. The quantity of endogenous cytokinins and peroxidases in pland cells were previously demonstrated to be intimately correlated to the virus disease resistance and tolerance. However, the mechanisms pertaining to the induced disease resistance and tolerance remain to be studied.

以室内和田间相结合的方法、病理和生理相结合的手段,进行了NS-83诱导抗性机制的探讨。室内试验表明,NS-83具有体外钝化TMV、抑制TMV初侵染的作用,经根部吸收可降低叶部的侵染;可诱导与抗性相关的细胞分裂素和过氧化物酶活性的增加。田间试验结果表明,在不同地区的番茄、辣椒、烟草上NS-83均具有降低发病率的抑制侵染作用和压低病情指数的治疗作用,推迟了田间发病。

The experiment utilized two induced─pathogens to inject in the stem of cucumber plant. The results showed that the active resistance and against to downy mitdew were improved, all the foliages lignin content of the injected plants were higher than the contrast plants, they were 7. 5%, 8. 4% and 7. 0%, respectly.

本研究采用已筛选出的诱导菌,进行茎部注射接种,活化植株的抗性潜能,增强抵抗黄瓜霜霉菌(Pseudoperonosporacubensisf.sp.cucumerinum)浸染的能力。进一步测定和分析木质素含量与诱导作用之间的关系。研究数据表明:凡经诱导处理的植株,叶片木质素含量均显著高于未诱导叶片中木质素含量。诱导叶片木质素含量分别为7.5%和8.4%,而对照株(未诱导)叶片木质素含量为7%。诱导抗性效应与木质素的形成有密切相关。试验结果说明,木质素合成量的提高,是植株抗性潜能被激活的结果,是诱导抗性机制的一部分。

The experiment utilized two induced nonpathogenic fungi to inject in the stem of cucumber plant. The results shown that the active resistance and against ability to downy mildew were improved. All the foliages sugar and lignin content of the induced plants were higher than the contrast plant. The sugar were 11.21%, 10.66% and 9.58%, respectively. The lignin were 8.4%, 7.8% and 6.9%, respectively. These data indicated the induced resistance caused by induced fungi related to the contents of soluble sugar and...

These data indicated the induced resistance caused by induced fungi related to the contents of soluble sugar and lignin, but also demonstrated that the contents of soluble sugar and lignin in cucumber plants were a part of mechanism of inducing resistance.

本研究采用已筛选出的诱导菌,进行茎部注射接种,活化植株的抗性潜能,增强抵抗黄瓜霜霉菌(Pseudoperonosporacubensisf.sp.cucumerinum)侵染的能力。进一步测定和分析木质素、糖含量与诱导抗性之间的关系。研究结果表明:凡经诱导的植株,叶片中可溶性总糖和木质素含量均显著高于未诱导叶片中的含量。诱导叶片中可溶性总糖含量分别为11.21%和10.66%;木质素含量分别为8.4%和7.8%;而对照株(未诱导)叶的可溶性总糖只有9.58%;木质素含量只有7%。试验结果表明,木质素和可溶性糖合成量的提高,是植物抗性潜能被激活的结果,是诱导抗性机制的一部分
