Grasslands study on level of distribution of Asclepias syrica

The study of 50 samples of Asclepias syrica was observed through a continuous measurement in centimeters along a transect tape. Research was conducted at the York University Arboretum grasslands on Wednesday, September 21st 2015. The study looked into the concentration of Asclepias syrica in areas of growth, along with the ordinal measurements of how many leaves and flowers each individual unit had. Study location in the grasslands was randomized by walking 20 meters forward from the outskirts of the area, placing a transect tape on the ground and running the tape until at least 50 samples of the species being observed were within one meter of the tape on either side. Looking at the data, there is no correlation between plant density and number of leaves and flowers on the plant. Leave and flower numbers appear to be random, with both many and few numbers of leaves and flowers appearing in areas of high and low density.

本研究通过沿样带卷尺开展厘米级连续测量，对50份普通马利筋（Asclepias syrica）样本进行观测。
本次研究于2015年9月21日周三，在约克大学树木园（York University Arboretum）的草原样地开展。
本研究旨在调查该物种在生长区域的种群密度，同时对每株样本的叶片数与花朵数进行有序计数测量。
采样点位采用随机布设方案：从研究区域外缘向前步行20米后，于地面铺设样带卷尺，沿卷尺两侧各1米的范围内采集至少50份目标物种样本。
经数据分析发现，植物种群密度与单株叶片数、花朵数之间不存在相关性；叶片数与花朵数呈现随机分布特征，无论种群密度高低的区域，均同时存在叶片数与花朵数较多和较少的样本。
