摘要: 本研究比较了葡萄霜霉病抗性鉴定中反应型与严重度两种鉴定标准。结果表明,两种抗性鉴定标准呈极显著相关,均可以反映葡萄植株对霜霉病的抗病性。反应型标准简便、准确、稳定,是定性的分级方法,而严重度标准可以反映植株抗病性的微小差异。

Abstract: Two standards to identify the resistance to P. viticola are compared in this paper. The results indicate both of the two methods could reflect the resistance to P. viticola of vine and has significant defference. The standard of infection type is a quatitative method which is simple, exact and steady, while the stardard of severcty can reflect micro resistant defference of vine.

Key words: PLASMOPARA VITICOLA, IDENTIFICATION, RESISTANCE, INFECTION TYPE, SEVERITY
