摘要
对糠椴、紫椴木质部的观察表明,木质部的解剖特征大体相同.分别测量了导管的直径、周长和面积.并从解剖学方面对糠椴、紫椴木质部进行说明.其中,紫椴木质部的导管直径较长,分布较均匀,有单孔的、双孔的和三孔的,其中双孔率高;紫椴木质部的导管直径较短,分布也较均匀,导管有单孔的、双孔的,但单孔的频率较高.这与他们特定的功能和生存环境相适应.紫椴的木质部要比糠椴的更进化一些.
The Tilia mandschurica,Tilia amurensis xylem observation showed xylem anatomical characteristics,they are roughly the same.Measured the catheter diameter,perimeter and area.And from the anatomy of Tilia mandschurica,Tilia amurensis xylem are explained.Wherein,Tilia amurensis xylem tube diameter is longer,uniform distribution,with a single hole,double and triple,wherein the double high rates of Tilia amurensis;xylem conduit diameter is shorter,distribution is uniform,the catheter has a single hole,double hole,but the hole with high frequency.This adapt to their specified functions and survival of the environment.
