我们找到半枫荷遗传多样性的分布热点推测出半枫荷的避难所，较低水平的遗传

We find Pterospermum distribution hotspots of genetic diversity inferred refuge Pterospermum the low level of genetic differentiation means in situ conservation and ex-situ conservation should be combined in Wuping, Sha County, Shunchang, Jiang Hua, Citylink, melt water and other places far from peaceful implementation of in situ conservation at the same time, the establishment of Altingia core germplasm bank as soon as possible. Origins conclusion can Pterospermum, systems development, protection and breeding provide the basic data.

We found the distribution of semi-maple lotus genetic diversity hot spot speculated that the shelter of semi-maple load, lower level of genetic differentiation means that the relocation protection should be combined with local protection, in Wuping, Sha County, Shunchang, Jianghua, Liancheng, meltwater and peaceful remote and other places to implement local protection at the same time, as soon as possible to establish a semi-maple load core seed resource bank. The conclusion of this paper can provide basic data for the origin, system development, protection and selection of semi-maple load.

We found the distribution hot spot of genetic diversity and speculated that the shelter of p.semiliquidae. The lower level of genetic differentiation means that we should combine the ex situ protection with the in situ protection, and establish the core germplasm resource bank of p.semiliquidae as soon as possible while implementing the in situ protection in Wuping, Shaxian, Shunchang, Jianghua, Liancheng, Rongshui and Pingyuan. The conclusion of this paper can provide basic data for the origin, phylogeny, conservation and breeding of schizophrenia superba.<br>
