摘要

苏格兰松+树的后代测试评估——确定改良种子在不同环境条件下使用前景的必要条件。本文介绍了在乌克兰北部大草原和南部森林大草原上根据一定特征选择的苏格兰松多株无性系的后代试验研究结果。结果分析表明：在气候和土壤条件较好的南部森林草原上，种子园的所有试验后代在3至10岁之间的生长率都有显著提高。与此同时，在北部草原不太理想的气候和土壤条件下，5个研究后代中有4个在3至26岁时的生长指标相对于当地对照恶化。草原条件下的领导者是三个无性系中的一小部分的后代，这些无性系具有最高的种子生产力。在两个试验点，选择生长最快的无性系和拒绝生长最慢的无性系对种子园后代的生长都有积极影响。

Progeny testing of Pinus sylvestris L. of seed orchard in different environmental conditions

Evaluation of the progeny test of plus trees of Scots pine - a necessary condition for determining the prospects the use of improved seeds in different environmental conditions. The paper presents the results of the study of the progeny test of groups of clones of plus trees of Scots pine selected according to certain characteristics in Northern Steppe and South Forest-Steppe of Ukraine. Analysis of results showed: a significant improvement in the growth rates of the all testing progenies of seed orchard in the better climatic and soil conditions of South Forest-Steppe between the ages of 3 and 10 years. At the same time 4 out of 5 studied progenies worsened their growth indicators relative to local control at the age of 3 to 26 years in less optimal climatic and soil conditions of Northern Steppe. The leader in the steppe conditions was the progeny of a fraction of three clones, which had the highest seed productivity. The selection of the fastest growing clones and the rejection of the slowest growing ones had a positive effect on the growth of progenies of seed orchards at both test points.

期刊介绍： The fundamental task set by the editors of the journal is to bring together and present a diversity of research connected with ecology. Apart from the traditional ecological research areas, the scope of the journal will embrace more peripheral ecological issues connected with other disciplines of biology. Recognizing the increasing importance of the humanities in ecological research, the editors will strive to give such issues due representation in the journal. We hope to encourage the researchers contributing to the journal to adopt an unconventional approach to solving ecological problems, to go beyond classical, well-established conceptions, and to include methodological and anthropological issues. Such an approach is validated by the intensive development of the sciences bordering on both biology and the humanities that has been observed over recent years.
