花生是我国重要的经济作物和油料作物,易被黄曲霉侵染.黄曲霉产生的黄曲霉毒素具有强毒性和强致癌性,严重威胁花生食品安全和人体健康,不利于花生产业健康发展.为了筛选抗黄曲霉侵染与产毒的花生品种,本研究采用孢子菌悬液侵染法,以 37 个花生品种的籽仁为试验材料,利用黄曲霉侵染指数和黄曲霉毒素B1(AFB1)含量分析比较各品种的抗侵染性.结果显示,37 个花生品种籽仁的黄曲霉侵染指数分布范围为 11.00%～80.33%,筛选出中抗黄曲霉侵染品种 13 个,中感黄曲霉侵染品种 19 个,感黄曲霉侵染品种 4 个和高感黄曲霉侵染品种 1 个,未筛选出高抗品种.AFB1 检测结果表明,黄曲霉毒素 B1 含量最低的 3 个花生品种为花育 23 号、花育 616 和花育9121.相关性分析结果表明黄曲霉侵染指数与 AFB1 含量呈显著正相关.
Screening of Peanut Varieties Resistant to Aspergillus flavus Infection and Toxicity
Peanut is an important cash crop and oil crop in China,and it can be easily infected by Aspergillus flavus.Aflatoxin produced by Aspergillus flavus has strong toxicity and carcinogenicity,which seriously threatens peanut safety and human health,and prevents the rapid development of peanut in-dustry.In order to screen the peanut varieties resistant to Aspergillus flavus infection and toxin production,the spore suspension infection method was used to study the peanut kernel of 37 peanut varieties,and the As-pergillus flavus infection index and the determination of aflatoxin B1(AFB1)content were used to analyze and compare the infection resistance of each variety.The results showed that the Aspergillus flavus infection index of 37 varieties of peanut kernel ranged from 11.00% to 80.33% .13 varieties with moderate aspergillus resistance,19 varieties with moderate aspergillus susceptible,4 varieties with aspergillus susceptible and 1 va-riety with highly aspergillus susceptible were screened out,and no variety with high resistance were found.The results of AFB1 detection showed that the 3 peanut varieties with the lowest content were Huayu23,Hu-ayu616 and Huayu9121.The correlation analysis showed that Aspergillus flavus infection index of different peanut varieties was positively correlated with AFB1 content.
