To sum up, the research for the first time ascertained INA species in apricot trees and their activities by using the rational method to imatate the temperature dropping process in frost nights--computer temperature controlling with semiconductor cooling and artificial frost box with self-recording. Studies were given to responds of INA to freezing temperature of floral organs, biochemical cold resistance parameters, contents of ABA and IAA, chlorophyll fluorescent parameters of young fruits and tissue structure and ultrastructure of apricot. The mechnism of INA induced frost injury of apricot was found out. And it was demonstrated that INA is a critical factor in the inducing and aggravation frost injury of apricot floral organs.

综上所述，本研究采用能够准确模拟自然界霜夜降温过程的较为理想的方法——半导体致冷电脑控温和自动记录的人工霜箱，首次查明了10个杏树品种上INA细菌种类和冰核活性，从INA细菌对杏树花器官过冷却点、抗寒生理生化指标、激素ABA、IAA含量、幼果叶绿素荧光参数以及组织结构和超微结构的影响等方面进行了系统深入的研究，阐明了INA细菌诱发杏树霜冻害的机理，证明了INA细菌是诱发和加重杏花霜冻害的重要因素。

So the present study was taken to compare the differences in the mechanisms of dissipating excess light energy in cucurbit crops and to study the differences in both the ROS metabolism in root system and the photosynthesis among six cucurbit crops with different temperature tolerance growing at different root-temperatures. The main results are as follows: 1、The species specific response of three cucurbit crops with different heat-tolerance: warm-adapted cucumber, heat-tolerant sponge gourd and heat-sensitive figleaf gourd to diurnal changes in air temperature and irradiance intensity were investigated in a typical summer sunny day. Three cucurbit species were compared using parameters in gas exchange, chlorophyll fluorenscence, photon allocation and photosynthetic electron flux.

因此，本试验以温度敏感性不同的瓜类作物为材料，研究了夏季自然条件下不同物种间在耗散过量光能的主要机制差异；探讨了它们对不同根际温度在根系活性氧代谢及地上部光合作用等方面的生理响应差异，所取得的主要结果如下： 1、在夏季晴天条件下，三种温度敏感性不同的瓜类作物：喜温的黄瓜，耐热性的丝瓜与热敏感的黑籽南瓜在气体交换、叶绿素荧光、光能分配及光合电子流对一天中温度与光照环境变化的响应上存在物种间差异和日变化特征。

Attacked by surface active agent, ocean micro-alga will be change their coloring matter for photosynthesis under the contamination of surface active agent, to result much phaeophytin-a.In addition, have assayed the surface property of the four kinds of surface-active agent.

在此基础上初步研究了表面活性剂对海洋微藻的毒性机理，找到了表面活性剂对海洋微藻细胞的攻击点是藻类的细胞膜，并且胁迫状态下的藻类细胞的光合色素组成发生变化，产生大量的脱镁叶绿素a，影响藻类的光合作用效率。

Na2FlBr4Cl4 shows the maximum algaecidal activity, and the MLC value is 40μM with illumination and 90μM without illumination. From the research on the Na2FlBr4Cl4 against the growth of algae and the content of chlorophyll a, we obtains that xanthene derivatives have little effect on the growth of algae at low concentration and can restrain the growth of algae at middle and high concentration.

呫吨类化合物对铜绿微囊藻的测试结果显示：供试样品中对供试藻种活性最强的是Na2FlBr4Cl4，其MLC值为在光照条件下为40μM，在无光条件下为90μM；通过Na2FlBr4Cl4对铜绿微囊藻的生长量以及叶绿素a含量的影响的研究发现，在较低的浓度范围内，呫吨类化合物对铜绿微囊藻的生长没有太大影响，而在中高的浓度范围内，则能产生显著的抑制效应。

The city green turf grasses are under seriously stress for the shading of tall buildings, trees and shrubs, and lead to the recession of turf grass, so the author studied for this problem; Taking three cold-season sods as test material, including Festuca rubra Pernille、Poa pratensis Kentucky and Agrostis Regent. Effects of different concentrations of uniconazole (S3307) on shade-tolerance of three turf grasses under shading situation were studied by testing long-term growth and physiological characteristics of them.; After treated with S3307, the contents of chlorophyll and soluble sugar increased, plant height decreased, leaves width and thickness increased. All of these indicated that S3307 can evidently improve shade-tolerance of three turf grasses with different shade-tolerance, the optimal concentration of uniconazole is 100~200 mg/L; The results are very useful and meaningful for improving quality of turfgrasses under shading situation.

高大建筑物、乔木及灌木遮荫会使用于城市绿化的草坪草受到严重胁迫，造成草坪草衰退，针对这一难题进行了研究；以耐荫性不同的冷季型草坪草匍匐紫羊茅派尼、草地早熟禾肯塔基、匍匐翦股颖摄政王为试验材料，研究了不同浓度的外源激素稀效唑(Uniconazole， S3307)处理对3种遮荫草坪草生理及生长变化的长期调控作用；经稀效唑处理，3种草坪草叶片叶绿素含量和可溶性糖含量增高，植株株高变低，叶片变宽、变厚，不同耐荫性草坪草的耐荫能力均得到显著提高，最适的处理浓度范围100~200mg/L；这在生产实际中有重要应用价值，特别对提高受遮荫胁迫的草坪质量具有重要意义。

And meanwhile, the result show that, stomatal restriction was the main factor of the net photosynthetic rate's decrease in the leaves of 4 Dactylis glomerata L. when stress in slight water stress and the non-stomatal restriction was the main factor of the net photosynthetic rate in the leaves of 4 Dactylis glomerata L.

盆栽控水条件下4份鸭茅光合作用机理的研究表明，随着干旱胁迫程度的加强，4份鸭茅种质的净光合速率、蒸腾速率、气孔导度及叶绿素含量均有较大幅度的降低，其中抗旱性强的ZXY04P-201下降的速度慢，幅度小，而抗旱性差的ZXY04P-239下降速度快，幅度大。

The result shows that the chitosan can increase the the amount of effective tiller, then the yield of both of cultivars of Zizania caduciflora is enhanced markedly, and the concentration of 45mg/L of the chitosan has the best effect. The activity of POD in leaves and the content of sucrose in product can be increased after using the chitosan, and the change of the chlorophyl content could be abated and the effect has a long duration, and the furthersome effect of chitosan on the activities of the CAT and the APX lasts in the prophase and the midphase of growth.
