栽培条件下三叶木通茎藤生长与主要气候因子的关系研究

用11个不同产地的野生三叶木通(Akebia trifoliate)自然单株进行栽培试验,对其5个茎藤生长性状与5个气候因子进行了典型相关分析。结果表明:温度是影响三叶木通茎藤生长的第一要素,月平均气温和月有效积温与小区总茎藤总长度、单株主茎长度和小区茎藤材积相关性最强;月平均相对湿度和月日照是影响三叶木通茎藤生长的第二要素,表现出高湿少光有利于茎藤生长,低湿足光有利于茎藤萌梢。

Relationships between Principal Climate Factor and Traits in Stem Growth of Akebia trifoliate under Artificial Cultivation

Artificial cultivation with Akebia trifoliate wild plant in 11 different habitats,and 5(stem's) character and 5 climate factors were carried out to analyze the canonical correlation.The results showed temperature is the first factor under the influence of climate conditions on it in changed area.There were maximum correlation between the monthly mean temperature,the effective accumulate temperature and the small-area long-stem,the small-area volume and main stem length.The relative humidity and light are the second one,expressing the stem bud will get more if the humidity is less and light is more,but the growth of stem will speed up if light is not enough and humidity is more.
