Abstract

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.

干旱气候下马铃薯形态、生理和生化参数的生产力和动态

摘要

使用中熟品种 (v.) Siversky 和中早 Tretyakovka v. Siversky v.结果证明比 Tretyakovka 的产量高 1.6 倍。Siversky v. 的地上生物量的特点是光合色素含量增加，蛋白质和脂质代谢指标的变异性更大，以及更强烈的氧化过程和抗氧化保护，这可能是其更高生产力的关键。多变量统计分析表明，2020年俄罗斯中部气候条件与生产力和单位叶面积气孔数、茎数、以及蛋白质中色素、磷脂、中性脂质和水溶性部分的含量。因此，形态和生理生化特性都会影响生产过程的进程和方向，从而影响特定品种的产量。
