摘要: 利用光学显微技术,对黄瓜(Cucumis sativus)和3种砧木:黑籽南瓜(Cucurbita ficifolia)、南瓜(C. moschata)、丝瓜(Luffa cylindrica) 根的解剖结构进行了比较解剖学研究,探讨了黄瓜及其不同砧木抗病性和抗涝性的植物体结构机制,结果表明:导管的管孔类型、管孔大小、管壁厚度、导管周围木纤维的数量及侵填体的有无等与抗病性相关。木栓厚度,通气组织,管孔直径和导管数量与抗涝性相关。

关键词: 黄瓜砧木, 抗病性, 抗涝性, 解剖结构

Abstract: Comparative anatomy research were carried out on root structures of Cucumis sativus and its three stocks i.e.: Cucurbita ficifolia,C.moschata,Luffa cylindrical by light microscope technology, and structure mechanism of anti-disease and anti-waterlogging within the Cucumis sativus+and its different stocks were also discussed.The results showed that: the type,and size of ressel holes the thickness of the vessel wall, the amount of xylem fiber around the vessel and whether with tylosis or not are closely related to the anti-disease character. The thickness of phellem, aerenchyma, diameter of vessel holes,and the number of vessels are related to the anti-waterlogging character.

Key words: cucumber stock, anti-disease character, anti-waterlogging character, anatomical structure
