在不同地理种源的夏橡叶中,研究了全量氮和主要灰分元素(钙、钾、磷)的含量。确定了橡树种子后代的一些地理变异性规律。表明在橡树物候变种的人工林中,叶的化学特性取决于它们的生长强度。目前,对研究不同种源的乔木树种子后代和无性后代的针叶化学成分,表现出极大的兴趣。作为在新的生长条件下,对它们营养状况的鉴定,其目的是要发现识别特征,它们能够在选种工作中被利用。最初得到了有关针叶化学成分变异性的可靠资料,这些资料是与种源紧密相关的。这说明继续进行这方面的工作是完全必要的,特别是阔叶树种,没有进行过这种类似的工作。我们分析营养物质成分的变异性途径,是为研究全量氮、钙、钾和磷在不同地理种源的橡树种子后代叶中的浓度。试
In different geographical provenance of summer leaves, the study of the total nitrogen and the main ash elements (calcium, potassium, phosphorus) content. Determine some oak seed offspring of some of the laws of geographical variability. It shows that the chemical properties of leaves depend on the strength of their growth in plantations of the oak species. At present, great interest has been shown in the study of the needle-leaf chemical constituents of the descendants and vegetative seeds of tree seeds of different provenances. The purpose of identifying their nutritional status under new growth conditions is to identify identifying features that can be utilized in the selection process. Initially obtained reliable information on the variability of needle chemical composition, the information is closely related with provenance. This shows that it is absolutely necessary to continue the work in this field, especially for broad-leaved tree species, and such similar work has not been conducted. Our approach to analyzing the variability of nutrient components is to study the concentration of total nitrogen, calcium, potassium and phosphorus in the leaves of oak seedlings of different geographic provenances. test
