[0102] S101: In the geographical distribution of Populus simonii across the country (Shaanxi, Qinghai, Hebei, Henan, Ningxia, Beijing, Inner Mongolia), 1233 samples of Populus spp. were collected, and we selected 235 individuals as representatives. In the cloning botanical garden in Guanxian County (36°23'N, 115°47'E), Shandong Province, China, the roots of these 235 individuals were used for asexual reproduction. In this study, these unrelated individuals were used to study the use of leaf phenotype data to predict net photosynthetic rate.
[0103] S102: Use the portable laser leaf area meter (CI-202) to measure the six leaf phenotype data of leaf area, length, width, circumference, aspect ratio and leaf shape factor.
[0104] S103: Combining average linkage clustering and PAM clustering, based on the leaf phenotype data obtained by CI-202 measurement, divide the 235 representative individuals into sub-species.
[0105] The average linkage clustering:
