| Abstract:
Differences of apple tree stock-scion combinations in response to mineral fertilisers have been revealed. It was found that activity of growth processes of apple trees determined by hormone balance of their genotypes may be a diagnostic criterion of their response to mineral fertilisation. The proposed criterion allows prognosing of apple tree (rootstocks, stock-scion combinations) reaction to the above-mentioned feature starting from the first year of life. | |
