随着辣椒植株年龄的增长，所有供试品种对疫病的抗性逐渐增强。高接种浓度的辣椒疫霉菌导致一些抗性品种出现症状。辣椒疫霉菌在抗病品种和老株上的潜伏期均长于感病品种和幼苗。土壤淋水接种法比茎段接种法更可靠。适当的筛选技术进行评估年龄相关的阻力进行了讨论
With increasing age of pepper plants, all cultivars tested became gradually resistant to Phytophthora blight. High inoculum concentrations of P. capsici resulted in symptoms on some resistant cultivars. The incubation periods of P. capsici in resistant pepper cultivars and old plants were longer than those in susceptible cultivars and young plants, respectively. The soil-drench method of inoculation was more reliable than the stem-inoculation method for evaluation of age-related resistance. Appropriate screening techniques for evaluation of age-related resistance are discussed
