| 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 water capacity and the content of chlorphyll in leaves,then the growth of wheat was inhibited,and the biological and economic yield were decreased.The inhibited extent of resistant genotype to low-phosphorus,Yanzhong 144 was bigger than that of non-resistant genotype,Chinese Spring.Under same condition,drought during the stage of tillering and booting could strengthen the effect of low-phosphorus. |
