9408739 Dufour This research involves a graduate student in anthropology from the University of Colorado studying how Colombian Indians use different varieties of manioc. This food plant is a staple in many tropical places, and grows in a "bitter" (i.e., poisonous) and "sweet" variety. The bitter varieties are often planted even though they require a long procedure of food processing in order to extract the poisons. The student will study the productivity of the plants, their disease resistance, how the people treat them and why they prefer some varieties to others, using a series of techniques including chemical analysis of the plants and cognitive tests of the farmer's perceptions of differences in the plants. Yields and damages to roots will be measured for sweet and bitter manioc in 20 family gardens and one control garden. This research will enhance our understanding of human adaptation to tropical rain forests, particularly to black water river systems. The knowledge to be gained will be valuable for agricultural planners and economic development advisers in all tropical areas where manioc is an important food plant.

9408739杜福尔这项研究涉及科罗拉多大学人类学专业的一名研究生，研究哥伦比亚印第安人如何使用不同种类的木薯。这种食用植物是许多热带地区的主食，生长在“苦”(即有毒)和“甜”的品种中。苦味品种通常是种植的，尽管它们需要很长的食品加工程序才能提取毒物。这名学生将使用一系列技术，包括植物的化学分析和农民对植物差异的认知测试，研究植物的生产力、它们的抗病能力、人们如何对待它们，以及为什么他们更喜欢一些品种而不是其他品种。将在20个家庭花园和一个对照花园测量甜木薯和苦木薯的产量和对根的损害。这项研究将加深我们对人类适应热带雨林，特别是黑水河流系统的理解。将获得的知识对所有热带地区的农业规划者和经济发展顾问都很有价值，因为在这些地区，木薯是一种重要的粮食植物。
