This award is to purchase a portable photosynthesis system that is integrated with a fluorescence monitoring system and a portable leaf area meter with a transport belt conveyor accessory. These instruments will be used in ongoing and newly planned projects in which measured photosynthetic rates will be correlated with developmental, symbiotic, and ecological factors. The research projects supported include the role of photosynthesis in the growth strategy and biomass allocation of clonal species in wetland ecosystems, the process of leaf senescence induced by the presence of maturing fruits in bean plants, and the use of CO2 fixation rates as an accurate predictor of nodulation and the rate of nitrogen fixation in the actinorhizal plant Elaeagnus umbellata. The purchase of the instrumentation will also help expand the range of available student research projects, and thus will serve as a critical resource for training undergraduate science students at Ithaca College.

该奖项是购买一个便携式光合作用系统，集成了荧光监测系统和便携式叶面积计与运输带输送机配件。 这些仪器将用于正在进行的和新计划的项目，其中测量的光合速率将与发展，共生和生态因素。 所支持的研究项目包括光合作用在湿地生态系统中克隆物种的生长策略和生物量分配中的作用，豆类植物中成熟果实的存在引起的叶片衰老过程，以及使用CO2固定率作为放线菌植物胡颓子中固氮和固氮率的准确预测因子。 购买仪器还将有助于扩大学生研究项目的范围，从而成为伊萨卡学院培养本科理科学生的重要资源。
