摘要
对12个核桃品种实生苗根部解剖构造及生长势进行研究,结果表明:材部面积与株高生长量呈极显著正相关,与株高显著正相关;材部面积占根横断面积的比例与株高生长量、株高显著正相关;材皮比与株高生长量、株高显著正相关;根部导管密度与株高生长量极显著正相关,与株高显著正相关;皮部面积占根横断面积的比例与株高生长量、株高显著负相关。
The results indicated that the area of wood and vessel density have positive correlation significantly with the increment of tree height, and have strikingly positive relationship with tree height. The rate of wood/transverse area and wood/bark have positive correlation significantly with the increment of tree height and tree height. The rate of bark/transverse area have strikingly negative relationship with the increment of tree height and tree height.
