大气CO2浓度升高对绿豆生长发育与产量的影响
EFFECTS OF AIR CO2 ENRICHMENT ON GROWTH AND YIELD OF MUNG BEAN
摘要
Abstract
Research on mung bean response to elevated [CO2]will benefit to learn about changes of mung bean yield under future climate change and possible corresponding measures.FACE ( Free air CO2 enrichment) was used in the study of mung bean.Results showed that the leaf area, height, node number and stem diameter increased with elevation of [CO2].Elevated [CO2]increased the youngest expanded leaf and the reciprocal 2nd expanded leaf area by 6.1% ~34.65% and 4.45% ~43.64%, respectively.Elevated [CO2]significantly increased the height, node number and stem diameter at mature by 19.56%, 8.24% and 9.71%, respectively.However, the content of chlorophyll in leaf decreased with elevation of [CO2].Elevated [CO2]significantly reduced the content of chlorophyll in the youngest expanded leaf at bud stage and flowering-podding stage by 1.53% and 14.21%, respectively.The content of chlorophyll in reciprocal 2nd expanded leaf decreased by 7.06% at the flavering-podding stage with elevated [CO2].The above-ground biomass weisht per plant was increased by 24.45% with elevation of [CO2].Because of the increase in pod number per plant, the yield per plant was increased by 13.87% in FACE, but the harvest index was descent.Elevation of [CO2]will stimulate the growth of mung bean.The above-ground biomass weight and the yield were promoted with elevation of [CO2].关键词
