| 摘 要： | 枯萎病、疫病、病毒病是冬瓜的3大主要病害。根据冬瓜的生长习性、广州的气候特点和3种病害的发生特点,建立适合冬瓜的多抗筛选技术体系。笔者从35份不同来源的冬瓜材料中筛选出2个多抗单株材料BD218-5-1和BD94-1-2,并获得相应的种子,以此为试材测定丙二醛、POD等5种生理生化指标,结果发现多抗材料与原始材料及其人工接种发病后在丙二醛、POD上发生了有规律的变化,其中多抗材料中的丙二醛含量低于原始材料,发病后均呈下降趋势,而POD则相反。

| Abstract: | Fusarium wilt,phytophthora blight wilt and viral disease of winter gourd(Benincasa hispida Cogn.)are the three kinds of the most important diseases.According to the growth habit of winter gourd,the characteristics of climate in Guangzhou,and the regularity of outbreak of the diseases,the paper established the screening technological system of multi-resistant diseases suitable for winter gourd.Two multi-resistant lines,BD218-5-1 and BD94-1-2,were obtained by screening from 35 different sources of materials.A... |
