落叶中解读生物节律

Interpretation of Biological Rhythms about Defoliation

为解释2021年兰州市城区一些落叶树未能落叶的异常现象,采用对话形式展开讨论。讨论结果认为,2021年兰州落叶树异常现象的原因是提前到来的寒流冻死叶片,导致叶片青枯在枝头。进而引用光周期、光敏色素、隐花色素、生物钟、生物节律等概念,以及最新研究成果,提出年生物钟新概念,解读了树木落叶的生理机制,并穿插介绍了一些关键性专业化思维技巧。讨论形成新认识:生物适应环境是生物主动响应环境节律性变化的过程,本质是向太阳对表。

In order to explain the abnormal phenomenon that some deciduous trees in Lanzhou city failed to shed their leaves in 2021,the discussion was conducted in the form of dialogue.It was concluded that the reason for the abnormal deciduous tree phenomenon in Lanzhou in 2021 was that the early cold wave froze the leaves and caused them to turn green and wither on the branches.Furthermore,the paper introduces the concepts of photoperiod,phytochrome,cryptochrome,biological clock and biorhythm,as well as the latest research results,proposes a new concept of annual biological clock,interprets the physiological mechanism of tree defoliation,and introduces some key professional thinking skills.The discussion formed a new understanding:biological adaptation to the environment is the process of biological active response to environmental rhythm changes,the essence is to follow the annual motion of the sun.
