可可(TheobromacacaoL·)在印度南部喀拉拉、卡纳塔克和泰米尔那德各邦广泛种植,由棕榈疫霉菌(PhytophthoraPalmivora)引起的黑果病有较大的经济上的重要性。可可不同品系类型对棕榈疫霉菌侵染的感病性是不同的。本研究是棕搁疫霉菌对十九个可可品种荚果伤侵染的反应。对可可树上接近成熟的果上接种于马铃薯、葡萄糖、琼脂(PDA)培养基培养了七天的棕榈疫霉菌的菌园块,接种后 TheobromacacaoL is widely planted in the states of Kerala, Karnataka and Tamilnadu in southern India, and there is greater economic importance for the black fruit disease caused by Phytophthora Palmivora. The susceptibility of different cocoa types to P. infestans infection is different. This study is the response of P. browning fungi to infection of 19 cocoa cultivars. The close-ripe fruit on the cacao tree was inoculated on the potato, glucose, agar (PDA) medium for seven days and cultivated for five days. After inoculation
