The Improvement of Laboratory Instruction and Student Research in Plant Ecology and Plant Physiology

学生可以通过使用新设备参与现代植物生态和生理学，包括生长箱、便携式光合作用测量系统、便携式叶面积计、数据记录器、便携式植物水分胁迫测量小室、分析天平和电泳仪。已经开发了一系列实验室练习来检查环境胁迫对植物的影响。使用新设备的练习包括：1.关于环境变化对植物生长、发育和繁殖的影响的实验室和田间研究；2.在受控环境条件下植物竞争的研究；以及3.检查种群中遗传变异性水平并测量由环境或遗传因素决定的多基因性状的变异比例的研究。

Students can participate in modern plant ecology and physiology with the use of new equipment including growth chambers, a portable photosynthesis measuring system, a portable leaf area meter, a datalogger, a portable chamber for measuring plant water stress, an analytical balance, and electrophoresis equipment. A series of laboratory exercises have been developed to examine the effects of environmental stress on plants. Exercises using the new equipment include 1. laboratory and field studies on the effects of environmental variation on plant growth, development and reproduction; 2. studies of plant competition under controlled environmental conditions; and 3. studies that examine levels of genetic variability in population and measure the proportion of variation in multi-gene traits determined by environmental or genetic factors.
