植物创可贴对创伤牡丹生长及丹皮酚含量的影响

Effects of Plant Woundplast on Growth and Paeonol of Wounded Peony

摘要:

Abstract: 目的：以牡丹为例研究植物创可贴对创伤植物的影响。方法：选择正常生长的牡丹进行根部取样，使用以草木灰为主要成分的植物创可贴进行创伤处理并观察植株生长状况，期间采用TTC法测种子活力，采用组织化学方法测定丹皮酚的含量。结果：取样后经植物创可贴处理的牡丹生长良好；与未经处理的植株相比，经处理的牡丹根中丹皮酚含量提高显著(P < 0.01)。结论：使用植物创可贴处理创伤植物不仅可以最大限度地节约药用植物资源、满足持续实验的需要，而且可在植物进行移栽等任何造成创伤时推广使用。

Objective: Taking Paeonia suffruticosa Andr. as an example to study the effects of plant wound- plast on wounded plants in this paper. Methods: Peonies in normal growth condition were chosen to obtain root sample. The wounds were treated with plant woundplast mainly containing plant ash and the growth of plant was observed. During the later growth time, seed vigor was tested by TTC method. At the same time, histochemical method was employed to determine the content of paeonol. Results: Those plants whose wounds were treated with plant woundplast after sampling grew well. Compared with those wounds non-treated after sampling, paeonol content of the former was enhanced remarkably (P < 0.01). Conclusion: This method of dealing wounded plants with woundplast can not only save medicinal plant resources maximumly and meet the need of continuous experiments, but also be used spreadly with those plants wounded during transplantion or other situations.
