上疏

喷4-CPA（4-氯苯氧乙酸）50PPm，强烈抑制顶梢生长，形成上疏下密株形；

4-CPA ( 4-chlorophenoxyacetic acid ) 50 ppm inhibited the growth of sprout made a thin upper and close lower form .

结果表明，受压扭组合作用的有重管柱的屈曲构型为上疏下密的螺旋曲线。

The results showed that the buckling configuration was helical curve for the gravitational tubular under the axial compressive force and torque .

据τR变化的趋势，推测TFP和JuA都是通过疏水作用结合到CaM上的疏水沟区，但两者的结合位点可能不同。

It is likely that both JuA and TFP bind on CaM through hydrophobic interaction , but the binding sites and ways of binding on CaM are different .
