摘要

该研究旨在分析在鞑靼斯坦共和国普雷德卡姆斯克地区条件下种植的春大麦品种谷粒的物理和机械特性。该研究于2015-2022年在俄罗斯科学院喀山研究中心塔塔尔斯基农业研究所(Tatarsky Research Institute of Agriculture FRC)进行。在普雷德卡姆斯克地区的条件下,平均而言,晚熟品种 "恩丹 "的1000粒重(48.5克)值较高,早熟品种 "卡玛舍夫斯基 "的自然粒重(686,3克/升)值较高,从2.8 x 20 毫米筛网(33.9 %)和粗度(70.02 %),中熟品种劳山 - 1000 粒重的变异性较高(18.6 %),2.8 和 2.5 x 20 毫米筛网的趋同性(分别为 55.6 % 和 29.7 %)和粗度(39.5 %)。千粒重、2.8 x 20 毫米筛孔径流量和粗度与降水量之和(r = 0.41/0.58/0.56,分别为 0.41/0.58/0.56)和 GTC(r = 0.40/0.58/0.55,分别为 0.40/0.58/0.55)直接相关,而这些物理和机械特性与 "抽穗-全熟 "间期的日平均气温(r = -0.51/-0.62/-0.63,分别为 -0.51/-0.62/-0.63)反向相关,显著性水平为 1%。从判定系数(r2)值来看,与日平均气温关系最密切的是 "千粒重"、"2.8 x 20 毫米筛孔漂移 "和 "粗度"。路径系数分析表明,2.8 x 20 毫米筛孔径流对谷物产量的直接正贡献(0.87)较高,而 2.5 x 20 毫米筛孔径流对谷物产量的平均直接正贡献(0.43)较低。在普雷德卡姆斯克地区,"年份 "因素对 "2.8 x 20 毫米筛孔流出量"、"粗度"、"千粒重"、"容重"、"2.5 x 20 毫米筛孔流出量 "等性状的总方差贡献最大,分别占(从大到小)81.7...80.3...76.6...76.2%、68.7%。分别占 68.7%。

Physical and mechanical properties of grain of spring barley varieties in the conditions of Tatarstan
The aim of the work is to analyze the physical and mechanical properties of grain of spring barley varieties cultivated in the conditions of the Predkamsk zone of the Republic of Tatarstan. The research was conducted in Tatarsky Research Institute of Agriculture FRC of Kazan Research Center RAS in 2015–2022. In the conditions of the Predkamsk zone, on average over the years of research, the late maturing variety Endan was characterized by reliably high values of 1000 grain weight (48.5 g), the early maturing variety Kamashevsky – reliably high values of natural grain weight (686, 3 g/l), convergence from 2.8 x 20 mm sieve (33.9 %) and coarseness (70.02 %), medium maturing variety Raushan – higher variability in 1000 grain weight (18.6 %), convergence from 2.8 and 2.5 x 20 mm sieves (55.6 and 29.7 %, respectively) and coarseness (39.5 %). The direct dependence of the mass of 1000 grains, runoff from the sieve 2.8 x 20 mm and coarseness on the sum of precipitation (r = 0.41/0.58/0.56, respectively), GTC (r = 0.40/0.58/0.55, respectively) and inverse dependence of these physical and mechanical properties on the average daily air temperature (r = -0.51/-0.62/-0.63, respectively) of the interphase period "earing-full ripeness" were established at 1% significance level. Judging by the value of the coefficient of determination (r2), the most closely related to the average daily air temperature are the signs "mass of 1000 grains", "drift from the sieve 2.8 x 20 mm" and "coarseness". The analysis of path coefficients revealed a high direct positive contribution (0.87) of 2.8 x 20 mm sieve runoff and an average direct positive contribution (0.43) of 2.5 x 20 mm sieve runoff to grain yield. Under the conditions of the Predkamsk zone, the prevailing contribution to the total variance of the traits "drift from the sieve 2.8 x 20 mm", "coarseness", "weight of 1000 grains", "bulk grain weight", "drift from the sieve 2.5 x 20 mm" was made by the factor "year", which accounted for (in descending order) 81.7...80.3...76.6...76.2. 68.7 %, respectively.
