Resource distribution of Acer truncatum based on specimens
摘要
Abstract
Acer truncatum is a deciduous tree of Sapindaceae and Acer.The samara,whose shape resembles the gold ingot of ancient China,is a unique oil tree species in China.In order to systematically study the geographical distribution and resource characteristics of A.truncatum in China,the geographical distribution pattern and resource characteristics of the main distribution areas of A.truncatum were analyzed by investigating the collections and existing literature of major digital herbarium at China and abroad.The results were as follows:A.truncatum was mainly distributed in 27 provinces regions/cities in Northeast and North China based on the 1 193 collected specimens.There were differences in leaf and fruit morphology in different regions,and the average fruit diameter of samples collected in Shaanxi Province was significantly larger than that in other regions.The collection place,collection time and other information of some of the samples were incomplete,and a few samples were incomplete due to improper collection or management.This paper provides a new idea and approach for studying the resource distribution of distinctive oil plants by using digital specimen resources.关键词
