Peanut stem and pod temperatures of plants growing in irrigated, drought, drought-heated soil, and drought-cooled soil treatments were determined near the end of the growing season. Mean soil temperatures of the treatments during this period were 21.5 degrees, 25.5 degrees, 30 degrees and 20 degrees C, respectively. Peanut stem temperatures in all drought treatments reached a maximum of ca. 40 degrees C and for 6-7 h each day were as much as 10 degrees C warmer than irrigated peanut stems. Pod temperatures in drought-heated soil and drought treatments were ca. 34 degrees C and 30 degrees C, respectively, for several hours each day. As pod temperatures approached the optimum for A. flavus growth (ca. 35 degrees C), the proportion of kernels colonized and aflatoxin concentrations increased. Increased plant temperature without accompanying pod temperature increases (drought-cooled soil) resulted in colonization percentages and aflatoxin concentrations only slightly higher than those of the irrigated peanuts.
在生长季末期测定了灌溉处理、干旱处理、干旱加热土壤处理和干旱冷却土壤处理中花生植株的茎部和荚果温度。在此期间，各处理的平均土壤温度分别为21.5摄氏度、25.5摄氏度、30摄氏度和20摄氏度。所有干旱处理下花生茎部温度最高达到约40摄氏度，且每天有6 - 7小时比灌溉花生茎部温度高10摄氏度。干旱加热土壤处理和干旱处理中的荚果温度每天分别有几个小时约为34摄氏度和30摄氏度。随着荚果温度接近黄曲霉生长的最适温度（约35摄氏度），被侵染的籽粒比例和黄曲霉毒素浓度增加。植株温度升高而荚果温度未随之升高（干旱冷却土壤）导致侵染率和黄曲霉毒素浓度仅略高于灌溉花生。
