Abstract

Abstract The aim of the research was to establish the patterns of soybean plants formation, depending on the matrix diversity of the sown seeds. Methods. Field experiments were conducted in the conditions of the right-bank forest-steppe of Ukraine (Kyiv agro-soil district of the right-bank forest-steppe). Factors of the experiment: factor A – variety (A1 – «Kyivska 98»; A2 – «Chernyatka»); factor B – the place of sown seed formation on the mother plant (B1 – lower tier (1–5th stem nodes), B2 – middle tier (6–10th stem nodes), B3 – upper tier (11th stem node and above), B4 – lateral branches). Soy was grown according to the technology traditional for the region, with the exception of the elements included in the experiment scheme. The influence of the studied factors on the growth of soybean plants was established by determining biometric indicators during the analysis of the sample bundle. The results. The analysis of plant height data indicates that the tallest plants of both soybean varieties were sown with seeds that were formed in the lower layer of the mother plants. The higher the sown grain was formed on the mother plant, the lower the plants that developed from it were. There is an inverse correlation between the height (tier) of seed formation on the mother plant and the height of the plants of the next generation, expressed by the correlation coefficient r = –0.517. Our analysis shows the existence of weak inverse correlation dependence between the place of seed formation on the mother plant and the number of nodes on the main stem in plants of the next generation: r = –0.504. A tighter inverse relationship exists between the place of seed formation on the mother plant and the number of nodes with beans on the main stem in plants of the next generation: r = –0.762. Correlation analysis indicates that the height of attachment of the lower beans, according to the experimental data we obtained, is connected by a direct correlation, expressed by the coefficient r = 0.913, with the height of plants and an average inverse correlation with the place (tier) of seed formation on the mother plant (r = –0.517). Conclusions. On the basis of experimental data, it was established that in the conditions of the Right-bank forest-steppe of Ukraine, biometric indicators of soybean plants depend on the variety, the place of seed formation on the mother plant, as well as on other conditions. Sowing with seeds formed in the lower tier of the main stem of mother plants causes the formation of plants with maximum plant height indicators (84.4 cm in «Kyivska 98» variety and 81.2 cm in «Chernyatka» variety), stem thickness at the root neck (6.1 mm in plants of «Kyivska 98» variety and 6.3 mm in plants of «Chernyatka» variety), the height of attachment of lower beans (17.9 cm in plants of «Kyivska 98» variety, 18.1 cm in plants of «Сhernyatka» variety).

There is an inverse correlation r = –0.782 between the tier of seed formation on the mother plant and the thickness of the stems near the root neck in the next generation plants. The height of attachment of the lower beans is connected by a direct correlation, expressed by the coefficient r = 0.913, with the height of plants and an average inverse correlation with the place (tier) of seed formation on the mother plant (r = –0.598).

大豆种子物质多样性及生物特征指标研究
摘要本研究旨在建立大豆种子基质多样性对植株形成的影响模式。方法。野外试验在乌克兰右岸森林草原条件下进行(右岸森林草原基辅农业土壤区)。试验因素:因子A -品种(A1 -«Kyivska 98»;A2 -«切尔尼亚特卡»);因子B -在母株上播种形成种子的位置(B1 -下层(1 - 5茎节),B2 -中层(6 - 10茎节),B3 -上层(11茎节及以上),B4 -侧枝)。大豆是按照该地区的传统技术种植的,除了试验方案中包含的元素。在样品束分析过程中,通过测定生物特征指标,确定了所研究因素对大豆植株生长的影响。结果。株高分析表明,两个大豆品种的最高株都是由母株下层形成的种子播种的。在母本上形成的籽粒越高,由其发育而来的植株越低。母株种子形成高度(层数)与下一代植株高度呈负相关,相关系数r = -0.517。我们的分析表明,在母株上形成种子的位置与下一代植株的主茎节数之间存在弱的负相关依赖关系:r = -0.504。母株种子形成位置与下一代植株主茎结豆数呈更紧密的反比关系,r = -0.762。相关分析表明,根据实验数据,下豆附着高度与植株高度呈正相关关系,系数r = 0.913,与母株上形成种子的位置(层)呈平均负相关关系(r = -0.517)。结论。在实验数据的基础上,确定了在乌克兰右岸森林草原条件下,大豆植物的生物特征指标取决于品种、种子形成在母株上的位置以及其他条件。播种的种子形成较低的层的主要干的植物植物的形成原因与最大株高指标(84.4厘米98年«Kyivska»多样性和81.2厘米«Chernyatka»品种),阀杆在根颈部厚度(6.1毫米在植物的«Kyivska 98»植物的多样性和6.3毫米的«Chernyatka»品种),附件的高度较低的bean(17.9厘米在«Kyivska 98»各种植物,植物的18.1厘米的«Сhernyatka»品种)。母株种子形成高度(层数)与下一代株高度呈负相关,相关系数r = -0.517。母株种子形成层数与下一代植株根颈附近茎粗呈负相关r = -0.782。下豆附着高度与植株高度呈正相关关系(r = 0.913),与母株上形成种子的位置(层)呈平均负相关关系(r = -0.598)。关键词:大豆;种子;生物特征指标;
