US-India Cooperative Research: The Effect of Light Quantity and Quality on the Developmental Ecology of Indian Tropical Forest Trees

描述：该提案是由佛罗里达国际大学的生物科学家David Lee和Madurai Kamaraj大学的Kailash Paliwal进行的美印合作。研究题目为：光照量和光照质量对印度热带森林树木发育生态的影响。研究人员将研究16种南亚原生热带森林树木的幼苗，以确定它们在光谱中性和改变的阴影条件下生长时，如何对光照数量和质量的变化做出反应。在10-15个月的时间里，将检查植物的生长速度、形态、叶片解剖和生理反应。研究结果将提高对该物种在自然条件下的生态反应、造林和苗圃建设的认识。这项研究将增加关于光照质量和数量对自然光条件下树木发育影响的基本知识。范围：这项研究将几乎完全在马杜赖卡马拉吉大学进行，由印度研究人员与美国PI David Lee密切合作，David Lee将在那里度过部分休假。这种方法是新颖的，应该会在热带森林树木再生的基础知识方面取得重大进展。本研究具有基础性和应用性。它将通过关注美国研究人员很少研究的地区，极大地加强美国的科学。作为一项涉及年轻科学家的新合作，该项目支持INT的目标。该项目将加强美国和印度之间的研究联系。这种互动是互利的。＊＊＊

9712753 Lee Description: This proposal is for a US-Indo collaboration between biological scientists David Lee, Florida International University and Kailash Paliwal, Madurai Kamaraj University. The research is: The Effect of Light Quantity and Quality on the Developmental Ecology of Indian Tropical Forest Trees. The researchers will study seedlings of 16 native South Asian tropical forest trees to determine how they respond to changes in light quantity and quality as they grow in spectrally neutral and altered shade conditions. Plants will be examined for growth rate, morphology, leaf anatomy, and physiological response over a 10-15 month period. Results will improve understanding of the ecological responses of the species in natural conditions, their sylviculture, and their establishment in nurseries. The research will increase fundamental knowledge about the effect of light quality and quantity to the development of trees in natural light conditions. Scope: This study will be conducted almost entirely at the Madurai Kamaraj University by Indian researchers in close collaboration with US PI David Lee who will spend part of his sabbatical there. The approach is novel and should lead to significant advances in fundamental knowledge about tree regeneration in tropical forests. The research is basic and applied. It will greatly strengthen US science by focusing on a region little studied by US researchers. As a new collaboration that will involve young scientists, this project supports INT objectives. The project will strengthen research links between the US and India. The interaction is mutually beneficial. ***
