摘要:

对石榴溃疡病害3菌株所引起的病害症状、病原菌的形态学特征、培养学特性、生理学特性及分子遗传多样性等方面进行比较研究。结果表明:石榴疮痂病与石榴果实上增生型症状的病原菌具有更近的亲缘关系,应为同一病原菌引起,推测该病原菌首先侵染石榴侵染枝干,然后侵染石榴的花萼和果实;而石榴干腐病病原菌主要侵染枝干,是否侵染果实及引起症状特征需要继续进行研究和鉴定。

Abstract:

The systemic relationship among the three strains of pomegranate canker diseases, the disease symptom, pathogen morphology, culture and physiological characters and molecular diversity was studied by comparison. The pomegranate scab and fruiting pathogen are belonged to same pathogen and deduced the pathogen infect to pomegranate stem or limb at first and infect calyces and fruit second, the pathogen of pomegranate stem rot mainly infect stem or limb, whether the pathogen infect fruit and produce symptom or not is needed to continue studying and identification.

Key words: pomegranate, scab, stem rot, fruiting disease, strains
