Abstract

: In this study we analysed changes in dis tribution and morphological properties of fine roots caused by underplanting of a 110-year-old Norway spruce monoculture by silver fir and common beech. Three different stand structures were investigated: mature established each quantified ic were calculated. Root-to-root interaction of spruce and underplanted species led to differences in verti cal distribution of roots towards the more homoge nous root density in investigated profile with clear shifting of beech and fir roots into deeper soil lay -ers. Cumulative root fractions of fir and beech in up per 20 cm were lower than those of Norway spruce. The share of spruce roots in depth under 20 cm never exceeded 20%. The co-occurrence of beech and spruce in small spots was about twice as fre quent as the co-occurrence of spruce with fir. We found differences in SRL and SSA between broad leaves (beech) and conifers, while the values of beech morphological parameters increased signifi -cantly, when mixed with spruce. We assume that the competitive strategy of beech is based in changing its root morphology, whereas silver fir is inclined to extend its biomass.

在成熟云杉林分下种植的银杉和普通山毛榉引起了根系分层和形态的变化

本研究分析了银杉和普通山毛榉对110年树龄挪威云杉的细根分布和形态特征的影响。研究了三种不同的林分结构，并对各林分结构进行了量化计算。云杉和林下树种的根-根相互作用导致根系垂直分布的差异，在调查剖面中，山毛榉和冷杉的根系明显向较深的土壤层转移，根系密度更均匀。杉木和山毛榉每20cm的累积根分数低于挪威云杉。云杉根系深度在20厘米以下的比例从未超过20%。山毛榉和云杉在小点上共现的频率大约是云杉和冷杉共现的两倍。我们发现阔叶(山毛榉)和针叶树在SRL和SSA上存在差异，而山毛榉的形态参数值在与云杉混合后显著增加。我们假设山毛榉的竞争策略是基于改变其根形态，而银杉倾向于扩大其生物量。
