This Doctoral Dissertation Enhancement award will provide funding for Amelia Henry, a PhD student at Penn State University to conduct field studies in Honduras under the guidance of Dr. Jonathan Lynch, Ms. Henry's thesis advisor and Dr. Juan Rosas of Zamorano University, Honduras. Dr. Rosas, will provide advice on the laboratory and data analysis components of the experiments. The research hypothesis to be tested questions whether planting genotypes of beans that differ in rooting depth will provide increased yields. Tests are designed around two bean genotypes differing only in their rooting depth. Trials include raising the genotypes separately, and in combination, with either adequate water and nutrients, or depleted water and nutrients. Genetic analysis will be used to determine the genotypes responsible for yield, and physiological measurements will be made to assess the mechanisms accounting for and growth or yield differences that occur from the use of multiline planting. The study addresses a broad range of questions and involves a variety of techniques, including molecular, organismal, and ecological components. Results from the study could address basic questions in root ecology that are highly relevant to food security in developing countries.

该博士论文提升奖将为宾夕法尼亚州立大学的博士生Amelia Henry提供资金，在Henry女士的论文导师Jonathan Lynch博士和洪都拉斯Zamorano大学的Juan Rosas博士的指导下在洪都拉斯进行实地研究。罗萨斯博士将为实验的实验室和数据分析部分提供建议。有待检验的研究假设是，种植生根深度不同的基因型豆子是否会提高产量。测试是围绕两种豆类基因型设计的，只是它们的生根深度不同。试验包括分别饲养基因型，或者用充足的水和营养物饲养，或者用耗尽的水和营养物饲养。遗传分析将用于确定影响产量的基因型，生理测量将用于评估多系种植造成的生长或产量差异的机制。该研究涉及范围广泛的问题，涉及各种技术，包括分子，有机和生态成分。这项研究的结果可以解决与发展中国家粮食安全高度相关的根生态学的基本问题。
