摘　　要：通过测定对果斑病表现不同抗性的哈密瓜品种的蜡质含量,结果表明:抗病品种种皮的蜡质含量与感病品种种皮蜡质含量存在显著性差异,抗病品种高于感病品种;在叶片上,接种后哈密瓜对果斑病的抗性与叶片的蜡质含量之间无相关性。可见,种皮的蜡质含量可作为衡量哈密瓜抗果斑病的1个参考指标。　Wax content of hamimelon varieties with different resistance to Acidovorax avenae subsp.citrulli was assayed.The results indicated that there was significant difference between wax content of seed-coat of the resistance variety and the susceptible variety,wax content of the resistant variety was higher than that of the susceptible variety,after being inoculated there is no apparent difference between Hamimelon resistance to Acidovorax avenae subsp.citrulli and wax content of leaves.So,wax content of seed-coat can be used as the referenced criterion to evaluate the resistance to the disease.
