思茅区季风常绿阔叶林木本植物结实情况研究初报

Preliminary Report on Seed Setting of Woody Plants of Monsoon Evergreen Broad-leaved Forest in Simao District

采用标准地及设置凋落物承接网并定期收集网内种子的方法,对云南普洱市思茅区木乃河季风常绿阔叶林木本植物及其结实情况进行了调查研究。结果表明,研究区乔木主要由短刺栲、厚皮香、光叶石栎、红木荷等优势树种组成;灌木则以水锦树、鹅掌柴、密花树、云南柃木等为主;层间植物以扁担藤、菝葜一种组成。短刺栲2月初开花,种子产量为86粒/m^2,种子千粒重为867.3 g,发芽率为89%;厚皮香5月初开花,种子产量为3粒/m^2,种子千粒重76.5 g,发芽率53%;红木荷4月中旬开花,种子产量为3粒/m^2,种子千粒重为2.7 g,发芽率为70%。其它植物种子未发现。

The woody plants of monsoon evergreen broad-leaved forest in Munaihe of Simao District,Pu′er City were studied by using the methods of sample plot and setting up litter receiving net to collect seeds regularly.The results showed that the dominant tree species in the monsoon evergreen broad-leaved forest were Castanopsis echidnocarpa,Ternstroemia gymnanthera,Lithocarpus mairei,Schima wallichi,etc.,while the shrubs mainly were Wendlandia uvariifolia,Schefflera octophylla,Rapanea neriifolia,Eurya obliguifolia,etc.,and the interlayer plants were composed of Tetrastigma planicaule and Smilax china.In early February,Castanopsis echidnocarpa bloomed with 86 seeds/m^2,1000-grain weight of 867.3 g,and germination rate of 89%.In early May,Ternstroeia gymnanthera bloomed with 3 seeds/m^2,1000-grain weight of 76.5 g and germination rate of 53%.In mid April,Schima wallichi bloomed with 1000-grain weight of 2.7 g,germination rate of 70%,and seed yield of 3 seed/m^2.No other vegetation seeds were found.
