摘要
通过对其苗期相对电导率、疫病、病毒病、叶片萎蔫指数、发芽率及胚根生长速度测定的实验方法对35份节瓜自交系材料的耐热性鉴定和评价。实验结果表明:叶片萎蔫指数、苗期相对电导率、发芽率以及胚根生长速度、45℃处理存活率可以综合评价节瓜的耐热性,并且利用这几个指标评价了35份材料的耐热性。
By determining the conductivities of seedling stage, phytophthora blight, virus disease, leaf wilting index, germination percentage and growth rate of radical, the identification of heat resistance of 35 Benincasa hispida eogn. var. chieh-qua materials was investigated. The resuhs showed that leaf wilting index, the conduetivities of seedling stage, germination percentage, growth rate of radical and survival rate under 45 temperature eould be a comprehensive evaluation of heat resistance of B. hispida, and the heat resistance of the 35 materials was evaluated.
