Abstract

The influence of tree species on basic density of wood, bark and small-wood was investigated here. Experimental material was obtained from 73 trees of 7 tree species, namely alder (Alnus glutinosa (L.) Gaertn.), beech (Fagus sylvatica L.), birch (Betula pendula Roth.), hornbeam (Carpinus betulus L.), Black locust (Robinia pseudoacacia L.), Sessile oak (Quercus petraea (Matt.) Liebl.) and Turkey oak (Quercus cerris L.) from the territory of Slovakia. Wood and bark samples were taken from discs cut from three trunk sections and from small-wood and branch parts coming from tree crowns. The volume of green samples was measured in graduated cylinders with a precision of 1 ml; a dry matter was measured with a precision of 0.01 g. The statistically significant effect has been shown in tree species, biomass fractions and locations on the tree. The average basic density of all species varies from 440 to 650 kg.m-3 for wood, for bark it is 380-670 kg.m-3 and for small-wood outside bark it reaches 490-650 kg.m-3. Alder and Black locust tree species have the lowest and highest wood density, Black locust and Turkey oak of bark and alder and Turkey oak of small-wood.

阔叶树种地上生物量基本密度。

研究了树种对木材、树皮和小木材基本密度的影响。实验材料取自7个树种的73棵树，山毛榉（Fagus sylvatica L.）、桦树（Betula pendula Roth）、角木（Carpinus betulus L.）、黑蝗虫（Robinia pseudoacia L.）、无梗栎（Quercus petraea（Matt.）Liebl.）以及来自斯洛伐克境内的土耳其橡木（Quercus cerris L.）。木材和树皮样本取自从三个树干部分切割的圆盘，以及从树冠上切割的小木材和树枝部分。在刻度圆柱体中以1ml的精度测量绿色样品的体积；以0.01g的精度测量干物质。在树种、生物量分数和树上的位置中显示了统计上显著的影响。所有物种的平均基本密度在440至650 kg.m-3之间，树皮为380-670 kg.m-3，树皮外的小木材为490-650 kg.m.3。木密度最低和最高的是Alder和Black蝗虫树种，树皮为Black蝗虫和土耳其栎，小木材为Alder和土耳其栎。
