将 Sullivang(1971,1972,提出测定细胞稳定性的技术,略加修改,可用以测定冬、春小麦的耐旱性。该技术将叶样浸于高浓度的聚乙烯乙二醇溶液中使其失水,再进行组织损伤的导电性测量。也讨论了细胞膜对干旱缺水(干旱锻炼))的调节。结果表明,这项技术对评价小麦的耐旱性是有效的。然而,耐旱性显著受叶龄、所采叶样在植株上的位置、取样时期、干旱锻炼的程度和干旱锻锻时的株龄所影响。 Sullivang (1971, 1972, proposed the determination of cell stability of the technology, with minor modifications, can be used to determine the winter and spring wheat drought tolerance of the technology leaves the sample immersed in high concentrations of polyethylene glycol solution to lose Water, and then conduct conductivity measurements of tissue damage.Moreover, the regulation of cell membranes on drought and water scarcity (drought exercise) is also discussed. The results show that this technique is effective in assessing drought tolerance in wheat. However, drought tolerance was significantly affected by leaf age, location of the sampled leaf on the plant, sampling period, extent of drought exercise, and age at forging.
