摘 要 ：研究了低磷和干旱胁迫对小麦（Triticum aestivum L.）生长发育的影响。结果表明，低磷胁迫能显著降低小麦的分蘖数、叶片相对含水量和叶绿素含量，进而抑制小麦的生长发育，降低其生物产量和经济产量，不耐低磷品种中国春受影响的程度要大于耐低磷品种烟中144。在相同条件下，干旱能够强化磷胁迫效应，表现出明显的胁迫叠加现象。

Abstract:The effect of low-phosphorus stress and drought stress during the stage of tillering and booting on growth of wheat (Triticum aestivum L.) was studied.The results showed that,low-phosphorus stress could sharply decrease the number of tillering,relative wa
