Динамика накопления аскорбиновой кислоты в надземной фитомассе Galega orientalis Lam.

Aim. To analyse the patterns of ascorbic acid content in the green mass of Galega orientalis (Galega orientalis Lam.), Gale variety, cultivated under introductory conditions to develop an effective method for increasing feed production. Material and Methods. The influence of the following factors on the accumulation of ascorbic acid in plants was considered: pre‐sowing seed preparation, the presence of a cover crop (pea), cultivation conditions, meteorological factors and the biological age of the grass stand over a three‐year period. Results. It was established that the plant mass of Galega orientalis is a source of ascorbic acid after plants enter the generative phase of development with predominant localization of vitamins in the leaves (96%). Patterns were revealed of ascorbic acid accumulation in the green phytomass of Galega orientalis depending on average daily temperature during the vegetation period (r = ‐0.69) and specific leaf surface (r = ‐0.83‐0.88). Conclusion. The data obtained also indicate a statistically significant positive effect of using Baikal‐EM1 microbiological fertilizer for seed inoculation during preparation for sowing, and a negative effect of the cover crop on the accumulation of ascorbic acid in the plant mass of Galega orientalis in its virginal and generative periods of development.
