摘要
本文分析了用于栽培黑松和樟子松幼苗的三种不同容器类型对其解剖学(树脂导管宽度、树脂导管数量、气管数量、气管宽度、木射线高度)和形态学(高度、根颈直径、坚固系数)要素尺寸以及木材、树皮和髓的比例的影响。两因素方差分析表明,容器类型对两种植物的所有研究解剖特征都有很大影响,但另一方面,这些物种之间的差异仅仅体现在气管宽度和木射线高度上。根据描述性统计,与塑料容器相比,生物可降解容器的所有研究解剖特征值都明显较低。在 Plantagrah I 中,黑木树苗的解剖学表现最好,而 Hiko V-120 SS 最适合西洋杉。生物降解容器中的髓和树皮比例最高。至于形态参数,如高度和根领直径,塑料容器的数值较高。
VARIABILITY OF ANATOMICAL AND MORPHOLOGICAL TRAITS OF PINUS NIGRA AND PINUS SYLVESTRIS SEEDLINGS AFFECTED BY DIFFERENT CONTAINER TYPE
In the paper was analysed the influence of three different container types, used for cultivation of Pinus nigra and Pinus sylvestris seedlings, on dimensions of their anatomical (resin ducts width, resin ducts number, tracheid number, tracheid width, wood rays height) and morphological (height, root collar diameter, sturdiness coefficient) elements, and on proportion of wood, bark and pith, as well. Two-factorial ANOVA showed that container type affects a lot all investigated anatomical traits by both species, but on the other side, these species varied between each other just in terms of tracheid width and wood rays height. Based on descriptive statistics, significantly lower values of all studied anatomical elements were recorded by biodegradable compared to plastic containers. As for P. nigra seedlings, they showed the best anatomical performance in Plantagrah I, while Hiko V-120 SS was the most suitable for P. sylvestris. The highest proportion of pith and bark was recorded in biodegradable container. As for morphological parameters, such as height and root collar diameter, higher values were recorded by plastic containers.
