为薰衣草精油用于防治樱桃番茄采后黑斑病提供依据,研究了薰衣草精油熏蒸和直接接触对病原真菌链格孢( Alternaria alternata)的抑制活性及作用方式。结果表明,在培养基培养试验中,每皿5μl的薰衣草精油熏蒸即可完全抑制病原菌的生长；当400μl/L薰衣草精油直接接触链格孢病原菌时,可完全抑制病原菌的生长。在薰衣草精油对樱桃番茄果实采后黑斑病抑制效果试验中发现,100μl/L精油熏蒸处理果实时,处理组果实发病率比对照组降低54%,用500μl/L精油直接处理果实时,处理组果实发病率则比对照组降低60%。在薰衣草精油对病原真菌链格孢作用方式试验中,薰衣草精油作用时间短时,对链格孢病原菌生长有抑制作用,薰衣草精油作用时间长时(5 d和7 d)对链格孢病原菌有致死效应。

This experiment was conducted to study the inhibitory effect and action mode of lavender oil against black rot in postharvest cherry tomato caused by Alternaria alternata by means of fumigation and direct contact. Lavender oil fumi-gation with the dosage of 5 μl per petri dish or direct contact at 400 μl/L could inhibit the growth of A. alternata complete-ly. The incidences of black rot were reduced by 54% and 60% in post harvest cherry tomatoes fumigated with 100 μl/L lavender oil and directly contacted with 500 μl/L lavender oil respectively. An inhibitory effect of short-time lavender oil treatment was shown on A. alternata while a lethal effect of long-time lavender oil treatment was exhibited.
