通过三种不同衰老类型冬小麦品种的比较研究表明，早衰品种的绿色叶面积持续期最短，叶片中的叶绿素含量、含氟量及光合速率和根系活力都较早的下降与丧失，各项生理参数的平均水平均低于正常衰老品种；青枯衰老品种的绿色对面积、叶绿素含量及光合性能持续期在参试品种中均为最长，但参数平均水平均为最低。表现为内部变化低下平缓，不能正常进入衰老阶段；正常衰老品种有较长的绿叶面积持续期，在收获期正好进入黄熟期，不早衰，不贪青，各项生理变化协调性好，数量与质量水平均较高。
Comparison of three wheat varieties with different senescence types showed that the duration of the green leaf area was the shortest, the chlorophyll content, fluoride content, photosynthetic rate and root activity of the leaves decreased and lost earlier. The physiological parameters The average green color area, chlorophyll content and photosynthetic duration of the aging cultivars were the longest among the tested cultivars, but the average of the parameters was the lowest. The performance of internal changes is low and gentle, can not normally enter the aging stage; normal aging varieties have longer duration of green leaf area, just in the harvest period into the ripe yellow, premature aging, not greedy, the physiological coordination of good, the number and Quality levels are higher.
