| 摘 要： | 采用菌悬浮液接种，对湘研系列的１５ 份辣椒材料进行抗疫病筛选，对其中抗感病水平不同的６ 份材料进行了抗性机制的研究．结果发现，湘研２ 号、５ 号、８ 号、９ 号、１９ 号和８５０１ 抗病性较好，病情指数低于４０，湘研七号、５９０５ 抗病性较差．抗性机制研究中发现，多酚氧化酶活性、苯丙氨酸解氨酶活性和可溶性蛋白质含量与抗病性呈正相关，而过氧化物酶活性与抗病性呈负相关．

| Abstract: | Fifteen varietiesof Xiangyan capsicums were screened for resistance to phytophthora blight, of which sixvarieties were used to study the resistance mechanism. Innoculation was carried out usingzoospores suspension culture. The aim of this research is to supply resistance-breedingfor pepper with reference and lay a foundation for comprehensive prevention of capsicumblight. It was found that Xiangyan capsicum varieties 2,5,8,9,19 and 8501 had good diseaseresistance, and disease index was less than 40,while Xiangyan 7,5905 were sensitive to thedisease. Disease resistance was positively correlated with the activities of PPD and PALand soluble protein contents, but negatively correlated with the activities of POX. |
