南方红豆杉扦插苗木生长量及与气象因子的灰色关联
A Study on Composition of Growth Guantities and Its Grey Sequence with Meteorological Factor in Cuttage Seedings of Taxus chinensis var marirei
【摘要】 南方红豆杉(Taxuschinensisvar.mairei)2种类型苗木(5年生灌木型扦插苗、5年生乔木型扦插苗)的生物量配置表现为:茎>叶>根,根冠比小于1,灌木型扦插苗的生物总量大于乔木型扦插苗的生物总量;产叶量灌木型扦插苗显著高于乔木型扦插苗(P<0.05)。气象因子与南方红豆杉茎枝生物量、枝条生长量(年生长长度、年分枝数量)灰色关联分析表明:日照和降雨量是扦插苗木茎枝干重增加、枝条伸长生长及年分枝数量的主要关联因子。
【Abstract】 Biomass configuration of arbuscle and arboroid cuttage seedings of five years old to Taxus chinensis var mairei showed that :stems>leaves>roots;root top ratio was less then one. Biomass of the arbuscle cuttage seeding was bigger than that of arboroid type. The quantity of leaves produced by the arbuscule type was obviously higher than that by the arboroid type(P<0.05).Sunshine and rainfall were important factors that increased the weight, growth and division of the stem according to the grey sequence analysis.
