喷洒液组分对香椿芽苗生长速度的效应关系分析

Research on Effect of Different Components of Spraying Liquid on Growth Rate of Sprouting Seedlings of Toona sinensis

本实验研究了不同喷洒液组分对香椿芽苗生长速度的效应程度。所获数据采用SPSS16.0统计分析,结果表明:(1)生长调节因子6-BA与GA3对香椿芽苗生长速度具有明显的调控作用(p<0.01);(2)营养元素对于香椿芽苗生长速度是一个无关变量(p>0.05);(3)蔗糖对香椿芽苗生长速度的影响具有明显的生长发育时期差异性;(4)喷洒液组分对香椿芽苗平均生长速度的回归方程为V=0.319A+0.583B+0.268C。

The effect of different components of spraying liquid on growth rate of sprouting seedlings of Toona sinensis from was researched. The results showed that 6-BA and GA3 played essential roles on growth rate of sprouting seedlings （p〈0.01）. Nutrient elements had no effect on growth rate of sprouting seedlings. The effect of sugar varied greatly between different growth periods of sprouting seedlings. Regression equation of different components on growth rate was V=0.319A＋0.583B ＋ 0.268C
