The authors observed in 1976 that all parts of plants contained the eazyme,hydrolase Ch,which catalytically hydrolyzed the substrate 2,6-dichlorophenol indophenol acetate,changing its color from light yellow to deep blue in aqueous solution.Like cholinesterase,the hydrolytic activity of hydrolase Ch may be inhibited by organic phosphorus compounds,but it differs from cholinesterase in that it does not catalytically hydrolyze acetylcholine bromide at pH 7-8,In this report,the distribution of hydrolase Ch in different...

The authors observed in 1976 that all parts of plants contained the eazyme,hydrolase Ch,which catalytically hydrolyzed the substrate 2,6-dichlorophenol indophenol acetate,changing its color from light yellow to deep blue in aqueous solution.Like cholinesterase,the hydrolytic activity of hydrolase Ch may be inhibited by organic phosphorus compounds,but it differs from cholinesterase in that it does not catalytically hydrolyze acetylcholine bromide at pH 7-8,In this report,the distribution of hydrolase Ch in different parts of plants was investigated.The activities of the enzyme in plants are in the following orders:seeds>leaves>stems>roots;new roots>old roots;dead leaves>growing leaves.More hydrolase Ch was found in the growing regions than in other parts and plays an important role in reproductive and vegetative development in plants.The velocities of recovery of activities inhibited by different pesticides were different.The methods may be used as a way to assess the quality of pesticides.

作者在1976年发现所有植物各部位中均含有可能是一种水解酶(暂定名为水解酶Ch),它能水解2,6-二氯乙酰靛酚,使水溶液由浅黄色变为深蓝色.酶活力能被有机磷农药抑制,但不能水解溴化乙酰胆硷.本文研究了水解酶Ch在植物各部位中的分布情况,发现酶活力大小顺序为;种子>茎>根;新根>旧根>败叶>叶,块根>通常根,即更多地存在于植物生命力旺盛的部位,它可能在植物生理学方面起重要作用.

Experimental resuts from yield loss studies with inoculation of two isolates of soybean mosaic virus in net cage, and with in vestigation of infection in epidemic field plots indicated that during early vegetative development of soybean plants, thinfection of SMV caused more serious losses than the infection after flowering beginning. After podding stage, the infection of SMV caused nearly no yield loss in the fields.The infection of the severe and mild isolates of SMV resulted in different yield loss signif-cantly. The severe isolate(83-02) caused 40% loss more than that of the mild isolate (83 -03).According to the analysis of conrrelation between the disease incidences during the various growing stages of soybean and yield losses of 30 group data, the disease incidences of 5 growing stages were used for stepwise regression calculation As a results, two predicting models of multiple- point and single - point for the yield losses of five susceptible soybean cultivars were obtained. The models were examined with 8 group data of actual yield losses other than in the setablishment of the models, good fittingness were observed between the actual and theoretical values. Through X2 - test, the above conclusion was also obtained. If the disease incidence was controlled to less than 3% after flowering stage, he yield loss caused by SMV could be controlled. The predicting models of yield loss would be benefitial to make the decision in disease management.

网室接种和田间调查测定SMV引致大豆的产量损失证明,SMV侵染大豆植株愈是在生育早期产量损失愈重。盛花期以后发病的植株产量损失显著减小,鼓粒初期的病株几乎无产量损失。SMV不同毒株引致的产量损失显著不同,强毒株的侵染,引致感病品种的产量损失平均超过弱毒株的40%。根据不同初侵染水平的30组SMV流行与产量损失数据,采用逐步回归分析,建立了准确度较高的产量损失预测多点模型和单点模型。根据损失测定,大豆盛花期的SMV病株率低于3%可控制SMV流行所造成的产量损失。

Roots play an important role in water and nutrient uptake by crop. The investigation of root system development of winter wheat and the effect of nitrogen, phosphorus and soil moisture on its growth in the North Plain of China was made in 1990 and 1991. Roots were sampled by coring and the changes of root weight and length were determined in five development stages. The root weight growth rates were 0.845, 0.386, 1.921, 2.500 and 0.427g / m2 · day and root length growth rates were 0.062, 0.0329, 0.310, 0.221km...

Roots were sampled by coring and the changes of root weight and length were determined in five development stages. The root weight growth rates were 0.845, 0.386, 1.921, 2.500 and 0.427g / m2 · day and root length growth rates were 0.062, 0.0329, 0.310, 0.221km / m2 · day in seedling, overwintering, jointing, heading and seed filling stages, respectively. The total root length and total root weight with time could be described by logistic growth function, and the exponential model was suggested for describing root system distribution with soil depth. N and P fertilizer application could promote the growth of winter wheat root system. Water stress reduced the root dry weight and root length, but root length and weight was greater in 0.3-1.20m depth under water stress than that of irrigated wheat. Irrigation could significantly increase roots in the stages of vegetative development and extend the root lifespan in the stages of reproductive development.

通过田间试验,采用大口径根钻取样研究了华北平原冬小麦根系生长的基本规律及其氮、磷肥和水分对根系生长的影响.结果表明,冬小麦根系生长时间分布规律是冬前较快,越冬不停,拔节至抽穗最快,抽穗后生长减缓并达到最大;根长和根重的增长遵循Logistic模型.空间分布规律是:冬小麦根系随土层深度的分布,无论是根长还是根重都是由上到下逐渐减少,遵循指数递减模型.施用氮肥和磷肥能显著促进冬小麦根系的生长.水分亏缺限制冬小麦根系的生长,但使根系分布下移.灌溉不仅能促进小麦根系前期的生长,而且可以延缓小麦根系后期的衰亡.
