Abstract

Florunner peanuts grown in research plots were subjected to 5 soil temperature and moisture treatment regimes resulting in A. flavus infestation and subsequent aflatoxin contamination in drought-stressed peanuts. Treatments imposed beginning 85 days after planting were drought, drought with heated soil and 3 drought treatments with cooled soil. The incidence of A. flavus in drought-stressed, unshelled , sound mature kernels ( SMK ) decreased with decreases in the mean 5 cm deep soil temperature. The incidence of A. flavus was greater in inedible categories and in damaged kernels than in SMK . The mean, threshold, geocarposphere temperature required for aflatoxin development during the latter part of the peanut growth cycle was found to be between 25.7 degrees C and 27 degrees C.

摘要

种植在试验田中的佛罗里unner花生经历了5种土壤温度和湿度处理方式,这些处理导致干旱胁迫的花生中出现黄曲霉侵染以及随后的黄曲霉毒素污染。种植85天后开始施加的处理包括干旱、土壤加热的干旱处理以及3种土壤冷却的干旱处理。干旱胁迫下、未去壳的健全成熟果仁(SMK)中黄曲霉的发生率随着5厘米深处平均土壤温度的降低而降低。黄曲霉在不可食用类别和受损果仁中的发生率高于SMK。在花生生长周期后期,黄曲霉毒素产生所需的平均、阈值、地下温度范围为25.7摄氏度至27摄氏度。
