Distribution and Eco-and Biological Characteristics of Early Blossoming Camellia Sect.Chrysanth Chang
摘要
Abstract
A Camellia group plant,known as the earliest flowering currently,was found recently in Daxin county, Guangxi. Its morphological characteristics differed from the other species, so we temporally named it as early blossoming Camellia. The geographic distribution,ecological and biological characteristics of the plant were fully investigated. The results showed that early blossoming Camellia mainly distributes in the 20 villages within Ganxu town in Daxin county and Zuozhou,Taiping town in Chongzuo city of southwest of Guangxi,locating at Karst region between longitude 107°16'~ 107°22'and latitude 22°30'~ 22°39'. The altitude is about 220 to 450 meters. The vegetable type, with some drought tolerance, belongs to shrub layer of Karst mountain seasonal rain forest. The community is the secondary forest in young and middle-aged; the species composition is complex,and the family and genera of tropical distribution pattern are dominated and have the proportion of 9. 0:1.0 and 8. 9:1.1 over that of temperate distribution pattern. The structure of the community is very simple: tree layer and shrub layer develop better while the herb layer is poor. The individuals of the plant exist mostly in the form of the complex stem, which can regenerate the population by means of sprouting and seedlings.关键词
