The Biofertilizers For The Root System Of Apple Rootstocks

The paper presents the results of research on the optimization of the main elements of adaptation and rearing of apple rootstocks in vivo.As a result of the conducted research, the main elements of the technological process of adaptation of apple rootstock plants M-9 and B-9 have been optimized.A consistent complex of nutritional regime is proposed for the effective growth and development of the root system of apple rootstocks, starting from the withdrawal of micro-plants in non-sterile conditions, up to the moment of forcing plants from the conditions of film greenhouses into field ones.The influence of a nutrient Knop's solution and biofertilizers "Lignohumate", "Samorod" and "Orengum" on the development, adaptation and rearing of apple rootstocks obtained in vitro in greenhouses has been studied.It was found that the use of biofertilizers had a significant impact on the formation and development of the root system, activation of growth processes and contributed to strengthening the protective properties of plants, as well as increasing resistance to adverse environmental conditions.The results obtained in the study can be used to work with the culture of cells and tissues of apple plants, in plant biotechnology and nursery, as well as in fruit growing to obtain a homogeneous healthy planting material of woody plants.
