摘要
在调查的基础上,结合有关文献和植物标本资料,对四川乡土果树资源的种类、地理分布进行了分析研究。结果表明:四川省有野生果树37科72属825种(含变种、变型和亚种),基本的果实类型有果、蒴果、瘦果、坚果、翅果、浆果、柑果、核果、梨果、聚合瘦果、聚合浆果、瘦果类聚花果和核果类聚花果等13种类型;野生果树垂直分布范围在海拔400m～4500m之间,主要集中分布于盆周山地,生境条件严酷的川西北高原区种类最少。此外,还对其开发利用前景进行了分析研究。
According to the investigation and plant specimen and collected documents,and after analysis of the fruit types and geographic distribution of native fruit trees in Sichuan,some conclusions are obtained,which are described in the following.825 species(including variety and form and subspecies) of wild fruit trees are found in Sichuan,which belong to 72 genara and 37 families.There are 13 basic fruit types such as follicle?capsule?achene?nut?samara?berry?hesperidium?drupe?pome?aggregate achene?aggregate berry?multiple achene and multiple drupe.These wild fruit trees are distributed in the scope of 400 m～4 500 m altitude,mainly in the edge mountains of the Sichuan Basin and there are few species in Northwestern Sichuan plateau with rigid environment.In addition,discussion are made on the developing prosperity of wild fruit trees in Sichuan in this paper.
