Physiological and Biochemical Parameters of Leaves for Evaluation of the Potato Yield

The aim of the study was to investigate morphological, physiological, and biochemical parameters leaves evaluate yield Solanum tuberosum L. We conducted 3-year experiments with 24 varieties potatoes, differing in ripeness groups (early ripening, mid-early ripening mid ripening). Plant height, linear dimensions, number stomata per unit leaf area as well content pigments, proline, membrane lipids proteins, level lipid oxidation each variety were investigated. A 3D modeling method showed early negatively correlated an increase temperatures (R = –0.97). soil moisture positively medium-early 0.97). tuber numbers mid-season had a negative correlation –0.96). regulation mechanisms processes cells depend on time variety. In order productivity improve potato quality, it is necessary take into account peculiarities regional climatic conditions use certain group. Our data refine understanding relationship between above-ground mass tubers.
