Rootstock Affects Scion Nutrition and Fruit Quality during Establishment and Early Production of ‘Honeycrisp’ Apple

‘Honeycrisp’ apple is susceptible to bitter pit, which associated with fruit mineral nutrient composition. Rootstock genotypes can affect acquisition, distribution, and yields, all composition pit susceptibility. However, the changes of these traits among different rootstock in response abiotic stress under semiarid conditions are relatively unknown. The objective this study was evaluate influence rootstocks irrigation on uptake partitioning grown an irrigated, environment. trees were grafted four rootstocks, Geneva 41 (‘G.41’), 890 (‘G.890’), M.9-T337 (‘M.9’), Budagovsky 9 (‘B.9’), planted at high density (3000 trees/ha). Irrigation applied as either a water-limited treatment where volumetric soil water content maintained near 50% field capacity (FC) well-watered control 100% FC. ‘G.890’, most vigorous rootstock, had lower nitrogen higher potassium leaves, while ‘B.9’, least content. genotype did not calcium uptake. Interestingly, increased root stems but leaves. Water-limited partitioned more roots, nutrients stems. Fruit size largest for ‘G.890’ smallest ‘B.9’. Both ‘G.41’ incidence, leaves fruit. These results suggest that rootstock-induced vigor both contribute imbalances could development physiological disorders apple.
