淹水条件下两个早熟禾品种的抗性研究

Study on the Resistance against Water with Two Cultivated Specieses of Poa L.in Waterlogging

考察不同水位梯度的淹水对早熟禾(Poa L.)2个品种:午夜(Midnight)和新哥来德(Nuglade)在叶长、 叶宽、叶绿素相对含量、叶面积指数及单株根系生物量等5个方面的影响。研究结果表明:在淹水情况下,2个品种的生 长均受到不同程度的抑制,但恢复生长较快,说明2个品种对于适度的涝渍具有较强的抵抗力。

Studied on the effect of the different water level steps with leaf length and width, chlorophyll relative content, leaf area index, root biomass per plant of two cultivated species (Midnight, Nuglade) of Poa L. The results showed that the growth of two cultivated specieses were restrained to the different extent, but restore growth was rapider, demonstrated that their resistance against water were higher.
