摘要: 大气CO2浓度升高使作物光合效率提高、生长速度加快、根系发达、株高增加、生育期缩短、产量提高、品质下降。因此,作物育种应培育相对晚熟品种,加强抗倒、抗病虫育种,注重品质改良。

关键词: CO2浓度, 作物育种, 形态性状, 光合生理

Abstract: With atmospheric CO2 concentrations elevated,increased the photosynthetic efficiency of crop,speeded upthe growth,enriched the root system,increased the plant height,shortened the growth period,increased the production,declinedthe quality.As a result ,we should be breed varieties to possess relatively late maturing,strengthen the lodging resistanceand disease resistance,improve the quality.

Key words: CO2concentrations, Cropbreeding, Morphologicalcharacters, Photosyntheticphysiology
