Usually a white spot can be observed on each leaf of these two species, but differences still exist. We aim to tell these two plants apart by comparing their leaves We measuredthe length and width of both the leaves and the white spots on them as well as the thickness of the thickest part of each white spot. Also we analyzed three ratios: leaf length to leaf width, spot length to spot width, and spot length to spot thickness. Not only are distinct differences found between the two species at the same elevation, the three ratios within one species also vary with the altitude rising. There's only one exception: significant difference in the ratio of spot length tospot width between two species doexistat an altitude of 1200m, but at other elevations the difference is unobvious Key words: Trifoliumpratense L, Trifoliumrepens L, ratio of the leaf length and leaf width, ratio of spot length and spot width, ratio of spot length and spot width2015 神农架野外生物学实习小论文 红白车轴草叶片、白斑差异及与海拔关系 王祎楠 张欣蕊 朱恩卓 杜明坤 刘振宇 王晓杰 张信果 宁清元融 （复旦大学生命科学学院，上海 200433, 武汉大学生命科学学院 2014 级生物学基地班二班，武汉，430072） 摘要：本文通过观察、测量红白车轴草叶片长宽与白斑长宽厚，计算红白车轴草叶片长宽 比，白斑斑宽/斑高，斑高/斑厚的数据，来比较红车轴草和白车轴草叶片及白斑的差异， 并寻找这些性质在不同海拔间的关系，寻找其规律，方便对车轴草分布的研究。比较发现 红白车轴草叶形、白斑形状等性状有明显差异，在数据方面叶长/叶宽和斑高/斑厚在各个 海拔上均有显著差异，但斑宽/斑高在 1200m 处有显著差异，在其他海拔上则没有。 关键词：红车轴草，白车轴草，叶长/叶宽，斑高/斑厚，斑宽/斑高 Difference between Trifolium pratense L. and Trifolium repens L. in leaves and its variation along with altitude Yinan Wang, Xinrui Zhang, Enzhuo Zhu, Kunming Du, Zhenyu Liu, Xiaojie Wang, Xinguo Zhang, Yu￾anrong Ningqing School of Life Sciences, Fudan University, Shanghai 200433 Class 2, School of Life Sciences, Wuhan University, Wuhan 430072 Abstract：Trifoliumpratense L. and Trifoliumrepens L.,both commonly found in Shennongjia, are quite similar to each other.Usually a white spot can be observed on each leaf of these two species, but differences still exist.
