移栽期间胁迫对苗木影响的研究进展

Recent Advances in Effects of Different Stresses in Transplant on the Seedling Performance

自起苗到栽植后的一段时间内,苗木会受到多种不利因素如失水、极端温度、根损伤的影响,其效应均不利于苗木的生长发育,据此提出移栽胁迫的概念,并对构成移栽胁迫的主要因素如失水、机械伤害、温度与多因子共同作用对苗木及栽植后的影响进行综述,在此基础上对该领域今后的研究方向和重点进行展望。

During lifting and planting, desiccation, harsh temperatures, root injury and other detrimental factors, would impede seedlings performance. All of these factors were harmful to seedlings, and were recognized as the transplanting stress. The recent advances in study of the effects of these factors were reviewed in this paper. More attention was paid on the performances of stock, and physiological indexes such as photosynthesis, chlorophyll fluorescence parameter, activity of different enzymes, were also described. Finally, the important and key aspects for future research are proposed.
