通过试验对２ 个春小麦品系在 Ｃ Ｏ２ 浓度倍增下的反应进行了观测，结果表明，在 Ｃ Ｏ２ 浓度倍增环境中，晚熟品系的全生育期缩短比早熟品系少。晚熟品系的生物量和产量增加比早熟品系更显著，因此，晚熟品系可能更适合于未来的全球变化。另一方面，２ 个品系春小麦的光合速率、地下和地上部分的生物量在 Ｃ Ｏ２ 倍增环境中增加显著，但籽粒产量的增加小于生物量的增加，意味着在 Ｃ Ｏ２ 浓度增加时经济系数将减小，其原因将进一步研究。从另外一个角度去考虑，这些特点可能会成为农作物适合于未来全球变化的另一个增产途径。
The experiment was conducted to test the responses of two spring wheat lines under the doubling of C O2 concentration. The results showed that the whole growth period of the late-maturing lines was shortened less than that of the early-maturing lines in the C O2 concentration doubling environment. Late-maturing lines are more pronounced in biomass and yield than early-maturing lines, so late-maturing lines may be more suitable for future global changes. On the other hand, the photosynthetic rate of spring wheat and the biomass of above-ground and above-ground parts of two cultivars increased significantly under C 2 O 2 doubling, but the increase of grain yield was less than the increase of biomass, which means that the economic coefficient Reduce, the reason will be further studied. From another perspective, these traits may be another avenue for crops to adapt to future global changes.
