%T Selection of Endophytic Antifungal Bacteria from Capsicum %D 2002 %R %J Chinese Journal of Biological Control %P 171-175 %V 18 %N 4 %X The endophytic antifungal bacteria were isolated and screened from Capsicum frutescens. Results indicated that population of endophytic bacteria ranged from 2.83×10 3 to 13.46×10 3 cfu per gram of fresh weight although it might vary depending on variety, tissue and planting location of the plant. Population of the endophytic bacteria were biggest in leaf, secondly in root, thirdly in stem and smallest in fruit. Leaf taken from capsicum planted in irrigated field harbored a bigger population of endophytic bacteria than that from non irrigated field. But for the endophytic bacteria in root, stem and fruit, plants growing non-irrigated field harbored more than that frowing in irrigated field. Of the 108 strains isolated, 28.7% expressed antagonism against growth of Fusarium oxysporum f. sp. cubense and Fusarium oxysporum f. sp. cucumerinum. Two of them (BS-2 and BS-1) were found not only to be inhibitive to the growth of some fungal pathogens, but also have 57.34%-94.08% control effect to the anthracnose caused by Colletotrichum gloeosporioides. These two strains were identified as Bacillus subtilis. %U http://www.zgswfz.com.cn/EN/
