中文摘要：巴基斯坦农民将种子和粮食储存在多孔聚丙烯（编织）和黄麻袋中或散装。储存在这些容器中的种子易受季节性相对湿度和温度波动的影响，从而促进霉菌和昆虫生长。本研究评估了普杜改良作物储存（PICS）袋储存的玉米种子在两个月时间内的性能。结果表明PICS袋在高相对湿度条件下能有效地保持玉米种子干燥，从而保持种子质量。
外文摘要： Smallholder farmers in Pakistan store their seeds and grains in porous polypropylene (woven) and jute bags or in bulk. Seed stored in these containers is susceptible to fluctuating seasonal relative humidity and temperature, which promote mold and insect growth. The present study assessed the performance of Purdue Improved Crop Storage (PICS) bags for maize seed storage during a two-month period. Seed moisture content increased in polypropylene bags while it remained constant in PICS bags. No change in germination was observed in maize seeds stored in PICS bags while in polypropylene bags it was reduced in half when compared to the initial germination. Seed stored in polypropylene bags had higher insect damage with a weight loss of 35% while in PICS bags the infestation was minimal with a weight loss of about 3%. Higher aflatoxin contamination levels were observed in seeds stored in polypropylene than PICS bags.PICS bags are effective at preserving the dryness of maize seed in storage during high relative humidity conditions, which leads to maintenance of seed quality.
