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

Abstract

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

The efficacy of selected local pesticides in prevention of leaf damage and improvement of yield in <i>Brassica rapa subsp. pekinensis L.</i> (Chinese cabbage)

“…A reasonable reduction of leaves due aphid invasion on vegetable was reported by Munthali and Tshegofatso (2014). The size and number of leaves are important attributes needed for controlling biomass accumulation and hence the yield of vegetable (Jefferies, 1995;Rozentsvet et al, 2022). Thus evaluation of vegetable leaves can be linked to leafy yield.…”

“…Potato ( Solanum tuberosum L.) is ranked fourth amongst all food crops in total production, following rice, wheat and corn worldwide (Rozentsvet et al 2022 ). Potato continues to be recommended as a key food for human consumption, especially when faced with the current population growth, leading to problems with food supply, nutrition and food security and climate change challenges globally (Beh et al 2022 ).…”
