摘要
对甜椒种子实施干热处理的结果表明 :经 40℃预处理 2 4h后 ,70℃干热处理 2 4h对种子表面真菌、细菌的防效分别达 40 %、 49% ,且不影响种子发芽和种子生活力 ,干热处理 48h的防效分别达 6 5 %、 5 5 % ;干热处理 72h的分别为 95 %、 6 4%。
The experiment of dry-heat treatment on the seed-carried fungi and bacterial in sweet pepper was done.The result showed the preventive effects of dry-heat treatment of fungi and bacteria reached 40% and 49%,65% and 55%,95% and 64% respectively when the treat times were 24h,48h and 72h respectively after seeds were pretreated at 40℃,The dry-heat treatment above(24h and 48h) did not affect the seed germination and the seed living strenth.
