Winter is a very complex biological traits, how to accurately and quickly identify drought of Northern dry winter wheat yield, and such vital importance. This experiment in 2009 and 2010 in a Northeastern University Laboratory of two different drought tolerance of winter wheat cultivars in permeability (electrical conductivity and protein content) changes to obtain viable winter index and identification methods. Keywords: winter wheat; drought resistance; soluble protein; electrical conductivity 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc263077263 摘要 PAGEREF _Toc263077263 \h I HYPERLINK \l _Toc263077264 abstract PAGEREF _Toc263077264 \h II HYPERLINK \l _Toc263077265 1 前言 PAGEREF _Toc263077265 \h - 1 - HYPERLINK \l _Toc263077266 1.1国内外研究文献综述 PAGEREF _Toc263077266 \h - 1 - HYPERLINK \l _Toc263077267 1.2冬小麦抗涝性鉴定指标的研究现状 PAGEREF _Toc263077267 \h - 1 - HYPERLINK \l _Toc263077268 1.2.1形态指标 PAGEREF _Toc263077268 \h - 1 - HYPERLINK \l _Toc263077269 1.2.2生理与生化指标 PAGEREF _Toc263077269 \h - 2 - HYPERLINK \l _Toc263077270 1.2.3水分利用效率 PAGEREF _Toc263077270 \h - 3 - HYPERLINK \l _Toc263077271 1.3冬小麦对我国农业经济的影响 PAGEREF _Toc263077271 \h - 3 - HYPERLI
