试验测定了石榴皮萃取物对番茄灰霉病菌室内抑菌作用和对番茄灰霉病的温室盆栽防治作用.室内抑菌试验分别采用生长速率法和孢子萌发法测定对番茄灰霉病菌菌丝生长和孢子萌发的抑制作用,结果表明:正丁醇萃取物对病原菌菌丝的抑制活性最高,EC_(50)为50.28 g/L;浓度为200 g/L对番茄灰霉病菌分生孢子的产生具有显著的抑制作用,抑制作用与浓度呈正相关关系.在温室盆栽试验中,正丁醇萃取物稀释100倍的处理对番茄灰霉病的保护防治效果达到46.41%,治疗防治效果达到48.00%.

The inhibitory effects of Punica granatum peel extracts against mycelial growth,conidial production and conidial germination of Botrytis cinerea was tested.The inhibition activities of the solvent extracts from pomegranate peels were measured in the laboratory by growth rate and spore germination method.The results showed that the effects were most significant in the petroleum,chloroform,ethyl acetate and n-Butanol,with the EC50 value as 50.28 g/L.The inhibitory effects of pomegranate peels against conidial germination were also correlated with the concentration.Significant inhibitory effects were also found in the extract of 200 g/L against conidial production,which Was correlated with the extract concentration.In green house trials,the results showed that n-Butanol extract of pomegranate peels had significant protective and curative effects on tomato grey mold at 100 times dilution,and the protective and curative control efficacies were 46.41%and 48.00%,respectively.
