摘要
为了对科学引种驯化和选育优质观果植物资源提供参考,比较了梵净山保护区和茂兰保护区秋、冬观果植物的物种组成、区系成分和优质观果资源种类的异同。结果表明,梵净山和茂兰两个保护区秋、冬观果植物资源虽然有90.32%的科和82.61%的属组成相同,但种的组成差异较大,相同组占37.21%;在属的区系组成结构上也有较高的相似性,都有世界分布、热带分布、温带分布和东亚特有分布4种区系成分,但种的组成比重上有细微的差异,尤其是热带分布和温带分布种的比重差异较大;茂兰保护区观果植物热带分布种的组成比重较梵净山保护区观果植物热带分布种的组成比重提高10.6%;茂兰保护区观果植物温带分布种的组成比重较梵净山保护区的比重降低12.08%;优质观果植物种类组成差异较大,共有种为17种,梵净山特有种21种,茂兰特有种14种。
To provide a scientific reference for introduction and domestication of high quality fruit plant resources,the species composition,floristic elements and the similarities and differences between the resource type were studied in Fanjingshan and Maolan Nature Reserve. The results indicated that the composition of 90. 32 % families and 82. 61 % genera were the same,but the species composition was different in large,and only 37. 21 % of the species composition of the same. The genus flora structure had higher similarity,only four kinds of floristic elements with the world distribution,tropical,temperate and East Asia endemic distribution,but there were subtle differences on the species composition proportion,especially the tropical and temperate species. The species composition proportion of tropical distribution of ornamental fruit plants in Maolan Nature Reserve increased by 10. 6 % than that of Fanjingshan Nature Reserve,but the temperate distribution was lower than 12. 08 %. There were great differences on the species composition of high quality fruit plant,the mutual species only 17. In addition,there were 21 high quality fruit plant in Maolan and 14 in Fanjingshan.
