CO2浓度倍增对冬小麦生长发育产量形成及发芽率的影响

The Influences of CO2 Concentration Doubling on Growth and Development,Yield Formation and Germination Percentage of Winter Wheat

    摘要
  • 摘要: 利用OTC-1型开顶式气室进行了CO2浓度倍增对冬小麦影响的诊断试验，结果表明，CO2浓度倍增对冬小麦生长发育、叶面积变化、生物量及产量形成等影响显著，且均为正效应。

     

    Abstract: The diagnostic experiment of influences of CO2 concentration doubling on winter wheat was conducted by using OTC-1 open top chamber.The results showed that when CO2 concentration was doubled in the chamber,growth and development,leaf area index,biomass and yield were all greatly increased compared with those in normal CO2 condition.This suggested that the increase of CO2 concentration in atmosphere will have positive effects on plant growth.
