几乎所有禾本科植物的形态都可以被概念化为亚基的分级排列，称为植物体。因此，了解植物个体的生长发育规律是阐明牧草生长节律的基础。本研究系统地分析了中国红豆杉的植物体发育过程。squarrosa，多年生C4草。植物单体内和单体间伸长的协调性是一个稳定的发育特征，因此，数量协调规则适用于预测C. squarrosa在对比水平的氮营养或蒸汽压赤字。
The morphology of almost all grasses can be conceptualized as a hierarchical arrangement of subunits, termed phytomers. Therefore, knowledge of phytomer growth and development serves as a basis to elucidate the rhythm of grass growth. This study provides systematic analyses on the process of phytomer development of C. squarrosa, a perennial C4 grass. The invariant coordination of elongation within and between phytomers was a stable developmental feature across treatments, thus the quantitative coordination rules are applicable for predicting morphological development of C. squarrosa under contrasting levels of nitrogen nutrition or vapour pressure deficit.
