环境因子对树木形成层活动及木质部发生影响的研究进展

Effect of environmental factors on cambial activity and xylogenesis

环境条件以及气候变化对树木径向生长的影响是全球关注的热点问题之一.影响树木径向生长的环境因素有很多,其中温度、日照时长、降水、干旱、融雪、氮沉降等都是重要的环境因子.本文综述了使用微树芯法监测的树木径向生长与环境因子的关系.一方面总结了环境因子对树木形成层活动及木质部发生影响的研究进展,另一方面提出了目前研究尚存在的问题并针对问题进行了展望,以期为进一步开展这方面的研究提供参考和依据.

Influence of environmental conditions and climate changes on radial tree growth is one of the hot issues worldwide.Numerous environmental factors such as temperature,day length,rainfall,drought,snowmelt,nitrogen deposition influence radial growth of trees.Impact of environmental factors on radial growth,cambial activity or xylogenesis of trees monitored by micro-core method is reviewed.The emphasis of the paper is on the modulation by environmental factors of cambial activity and xylogenesis,relevant problems and prospects are also outlined,to facilitate future research in this area.
