Interrelation between the morphology, physiology, biochemistry, and productivity of potato plants was shown for the first time using the example of a mid-season-ripening variety (v.) Siversky and a mid-early Tretyakovka v. The yield of Siversky v. turned out to be 1.6 times higher than the yield of Tretyakovka. Aboveground biomass of Siversky v. was distinguished by an increased content of photosynthetic pigments, a greater variability of the protein and lipid metabolism indicators, and more intense oxidation processes and antioxidant protection, which can be the key to its greater productivity. Multivariate statistical analysis showed that the greatest relationship in the climatic conditions of central Russia in 2020 was found for productivity and such indicators as the stomata number per unit leaf area, the number of stems, and the content of pigments, phospholipids, neutral lipids, and water-soluble part of the protein. Thus, both morphological and physiological-biochemical properties can influence the course and direction of the production process, and, hence, the yield of a certain variety.
首次以中熟品种（v.）Siversky 和中早熟 Tretyakovka v.为例，展示了马铃薯植株的形态、生理、生物化学和生产力之间的相互关系。Siversky v. 的产量比 Tretyakovka 高出 1.6 倍。Siversky v. 的地上生物量表现出光合色素含量增加、蛋白质和脂质代谢指标变化更大以及氧化过程和抗氧化保护更强烈的特点，这可能是其更高生产力的关键。多元统计分析表明，在 2020 年俄罗斯中部的气候条件下，生产力与单位叶面积的气孔数、茎数以及色素、磷脂、中性脂质和蛋白质水溶性部分的含量等指标之间的关系最大。因此，形态和生理生化特性都可以影响生产过程的进程和方向，从而影响特定品种的产量。
