摘要:
为使生长素更好地调控作物根系发育和生长，以玉米为材料，吲哚丁酸钾（IBA）∶α萘乙酸钠(NAA)=1∶4为生根剂，设置不同浓度梯度，研究外源生长素对玉米根系生长的影响。结果表明：随施用浓度的增加，生根剂对玉米幼根生长的促进作用呈现先增强后又减弱的趋势。其中，生根剂浓度为20 mg·L-1时对玉米幼根促生效果最佳，可有效增加总根长、总根表面积及根分枝数，降低根平均直径，对地上部鲜重和株高也有明显的促进作用。
Abstract:
In order to regular the crop root development and growth by auxin，taking maize as the experiment material,indole butyric acid (IBA): naphthylacetic acid (NAA)=1∶4 as the rooting agent,different concentrations of exogenous auxin were set to study the effect of the rooting agent on the maize radicle growth.The results showed that with increasing concentration of rooting agents,the maize radicle growth showed a trend of promoting first and then the promoting effect weakened.When the concentration of the rooting agent was 20 mg·L-1,the growth of maize radicle was the best,which could effectively increase the total root length,total root surface area and root branching number of the radicle,and reduce the average diameter of root.And the shoot fresh weight and height also were significantly increased.
