摘要

本研究的目的是确定采集样品的植被期长度对豌豆种子中蛋白质百分比的影响。这项研究于2017年至2020年在罗斯托夫地区南部对FSBSI«ARC«Donskoy»油田进行。研究对象是来自N.I.Vavilov ARIPGR(VIR)的100个豌豆样本,包括53个无叶样本和47个有叶样本。采集的平均植被期最长(93.8天)是在2017年确定的。用变异系数表示,该性状今年的品种间变异性为5.5%,最小值为63天,最大值为101天。在无叶型品种组中,品种间变异率为6.4%(最小63天;最大100天),在有叶型品种中为4.2%(最小80天;最大101天)。在其他年份,植被期减少,品种间变异性降低,这是由于不利的天气条件,即在气温升高和高温的背景下缺乏和缺乏降水。但它们也导致了采集样本种子中蛋白质的最大积累,从而显示出该指标的最大品种间变异性。相关系数的计算表明,蛋白质百分比对植被长度的相关性不存在,无论是对集合的平均值(r=0.03+0.10),还是对无叶(r=0.08+0.14)和有叶(r=0.05+0.15)叶片形态类型的组的平均值。叶形形态类型组的带误差图的构建显示样品的蛋白质百分比超过25.0%。在无叶形态类型的组中,它们的植被期分别为78–80和83–85天,而在有叶形态类型组中,研究多年来的平均植被期为77–79天。

The effect of a vegetation period on protein percentage in seed of the pea collection samples
The purpose of the study was to identify the effect of the length of a vegetation period of collection samples on protein percentage in pea seed. The study was carried out in the southern part of the Rostov region on the fields of the FSBSI «ARC «Donskoy» in 2017–2020. The objects of the study were 100 collection pea samples from the N. I. Vavilov ARIPGR (VIR), including 53 leafless samples and 47 leafy ones. The longest vegetation period on average for the collection (93.8 days) was identified in 2017. The intervarietal variability of this trait, expressed by a variation coefficient, this year was 5.5 % with a minimum value of 63 days and a maximum of 101 days. In the group of varieties of the leafless type, the intervarietal variability was 6.4 % (min. 63 days; max. 100 days), in the leafy group it was 4.2 % (min. 80 days; max. 101 days). In other years, there was a reduction of a vegetation period and a decrease in its intervarietal variability due to unfavorable weather conditions in the form of a lack and shortage of precipitation against the background of elevated and high air temperatures. But they also led to the maximum accumulation of protein in seeds of collection samples, thereby showing the greatest intervarietal variability of this indicator. The calculation of the correlation coefficient showed the absence of a correlation dependence of protein percentage on length of vegetation, both on average for the collection (r = 0.03+0.10) and for the groups of leafless (r = 0.08+0.14) and foliate (r = 0.05+0.15) leaf morphotypes. The construction of graphs with errors for groups of leafy morphotypes revealed samples with a protein percentage of more than 25.0 %. In the group of the leafless morphotype, they had a vegetation period of 78–80 and 83–85 days, and in the group of the leafy morphotype, it was 77–79 days on average over the years of study.
