不同水分条件下桃树根系的分形特征

The Root Fractal Character of Peach in Different Water Conditions

根系结构是影响植物生长的重要因素,利用分形维数可以对根系的形态结构进行定量化的描述。通过对不同水分条件下盆栽桃树根系的分形维数(FD)值进行研究发现,水涝处理根系的分形维数值最小,干旱胁迫也使维数变小,先干旱后复水促使维数值变大。

The root structure is an important factor for plant＇s life. We can get quantitative description of root structure from fractal dimension （FD）. From the study of potted peach we found that the value of FD was diverse in different water condition. FD value in flooding and drought treatment was smaller than ck. FD value of recovery treatment was bigger than that of control group.
