AT试剂对春茶光合生产的调控研究

应用ＡＴ试剂处理春茶，能提高越冬留养叶的光合速率，加速光合产物输出，增加叶片叶绿素含量，增加新梢的干物质积累。ＡＴ试剂在提高光合速率的同时，还使硝酸还原酶和过氧化氢酶活性下降。     

Plant growth stimulation by inoculation with symbiotic and associative rhizosphere microorganisms

SelectedRhizobium bacteria, arbuscular mycorrhiza-forming (AM) fungi and associative bacteria have been shown to stimulate the growth of legumes, gramineae and cruciferae in field experiments on different soil types in temperate regions. A combination of microorganisms with different metabolic capacities (N₂-fixation, P-mobilization; production of phytohormones and antibiotics) can partly surpass the effect of single inoculations, or can produce a positive effect where single inoculations are ineffective. Growth stimulation by inoculation requires microorganisms with phytoeffective metabolic characteristics and the ability to survive in the rhizosphere during the growth period. Another prerequisite is an adequate supply of plant assimilates for the production of microbial phytoeffective metabolites. Type of inoculum, method of inoculation and agricultural measures can influence the effect of the inoculation. Research is necessary to extend our knowledge both of basic principles, and about using microorganisms in practice.     

全程序微波辐射制备高等植物SEM样品的研究

本文以五种豆科植物和一种禾本科植物为材料，较为详细地研究和摸索了全程序微波辐射制备高等植物扫描电镜（ＳＥＭ）样品的条件和方法。结果表明。几种植物均能通过全程序微波辐射（包括半程序微波辐射）制得理想的ＳＥＭ样品。微波辐射制样的适宜条件为：固定、脱水、置换时的浸泡液终止温度３０±２℃，干燥终止温度７０±３．℃干燥时间３一一４ｍｉｎ。

二十七点九态控制器及其三阶对象仿真分析

介绍二十七点九态控制器的模型和控制作用。此控制器将相空间分为二十七个工作区域，而被控对象由九条不同规则控制。在此控制器作用下对不同的三阶对象进行稳定性仿真分析及其正弦跟踪分析，可得出结论：无论三阶对象是否稳定，在此控制器作用下对于不同的三阶对象可以达到满意的控制效果。     

Growth,development, feeding preference,and food consumption and utilization by tobacco hornworm on tobacco mosaic virus-infected and non-infected tobacco leaves

Summary Plant disease may cause a variety of changes in plants which influence their suitability to insect herbivores. The reported physiological changes in tobacco due to infection by tobacco mosaic virus have the potential to influence the feeding, growth and behavior of the tobacco hornworm,Manduca sexta. However, feeding on foliage of systematically infected plants had no statistically significant effects on development time, mean pupal weight or the amount of foliage consumed by 4th instars. Although an initial preference was exhibited by larvae for healthy leaves after about 72 h no differences were observed. These results do not support the results of previous research on the influence of tobacco mosaic virus-infected plants on the tobacco hornworm.Scientific contribution No. 8130, article No. A-5071, of the Maryland Agricultural Experiment Station, Department of Entomology
