为了研究半枫荷种群的遗传结构，我们使用STRUCTURE软件来计算种群

In order to study the genetic structure Pterospermum population, we use the STRUCTURE software to calculate the genetic structure of populations. Evanno method using the tag data into SRAP STRUCTURE software, the posterior probability LnP (D) and a corresponding logarithmic value of Delta K likelihood function scattergram obtained after workup was STRUCTURE HARVESTER, to obtain the maximum value of Delta K K = 2 (FIGS. 2a and FIG. 2B), followed by K = 7, illustrates a genetic structure, Pterospermum can be divided into two groups, and can be further subdivided into seven subgroups (FIGS. 3a and FIG. 3b).

To study the genetic structure of the semi-maple population, we used STRUCTURE software to calculate the genetic structure of the population. Using Evanno's method, the data of SRAP tag is imported into THE STRUCTURE software, and after processing by STRUCTURE HARVESTER, the post-mortem probability LnP (D) and the logarithm of the corresponding Delta K value are the logarithm-like scatter plot, and the maximum Delta K value is K. 2 (Figure 2a and Figure 2b), followed by K-7, shows that, depending on the genetic structure, semi-maple lotus can be divided into two groups and can be further subdivided into 7 subgroups (Figures 3a and 3b).

In order to study the genetic structure of the population, we use the structure software to calculate the genetic structure of the population. Using evanno's method, the SRAP labeled data was imported into structure software, and the posterior probability LNP (d) and the logarithmic likelihood function scatter plot of the corresponding delta K value were obtained after structure havester processing. The maximum delta K value was k = 2 (Fig. 2a and Fig. 2b), followed by K = 7. According to the genetic structure, half Maple can be divided into two groups, and further subdivided into seven subgroups（ Fig. 3a and Fig. 3b).<br>
