植物器官生理年龄划分方法的研究

生理年龄是植物学家为描述植物生长过程而提出的,它的合理划分对于分析树木的生长变化规律、构建树木的生长模型具有重要意义。对于拓扑结构复杂的多年生高大树木而言,生理年龄的划分并不简单,目前还没有一个系统的划分方法。为了快速、合理地划分植物各器官的生理年龄,基于欧美杨107的实测数据,根据生理年龄的概念,提出了一种自动划分多年生高大树木生理年龄的新方法。结果表明:本文提出的划分方法是可行的,并在一定程度上克服了人工方法存在的误差大、操作复杂等问题。该方法也可以被借鉴应用于其他多年生树木生理年龄的确定。

Defining physiological age of plant organs

Physiological age ( PA),proposed by botanists,is used to describe the growth process of plants.Rational division of PA plays an important role in the analysis of the growth rhythm of plants and the establishment of tree growth models.However,it is difficult to classify the PA for tall perennial plants with a complex topological structure and,until the present,no systematic methods have been developed.In order to classify the PA of plant organs quickly and suitably,we propose a new automatic method for divid...
