Keywords:Golden Delicious, 1-Methylcyclopropene, Smart Fresh, rootstock, harvest date, storage, soluble solids, titratable acidity
AbstractThe aim of this study was to investigate the influence of orchard design; harvesting time and postharvest treatment with 1-methylcyclopropene (1-MCP) on the change of the content of soluble solids and titrated acids during storage of apples cv. Golden Delicious of mass and delayed harvest dates from intensive orchard on dwarf (M.9) and traditional orchard on middle-vigorous (MM.106) rootstocks. The fruits were cooled to 5 ° C and then treated with 1-MCP and stored for up to seven months at the temperature of 2 ± 1 ° С and relative humidity of 85-90% (without treatment – control). The content of soluble solids was periodically measured with a refractometer and the content of acids (in terms of malic acid) was determined by titration. It was established that after a seven-month storage the content of soluble solids in apples from the intensive orchard was higher by 1.4-1.9%. Regardless of the harvest date at the end of a seven-month cold storage a post-harvest treatment with 1-MCP provides 0.4-0.9% higher level of soluble solids compared to untreated fruits; and 1.1% higher level for the apples of both harvesting dates from the traditional orchard. During storage the content of titrated acids reduces slightly faster in the late collected fruits and it was higher after a seven-month storage in untreated apples from an intensive orchard. At the end of a seven-month storage a post-harvest treatment with 1-MCP provides 1.5 higher level of organic acids in the fruits of both harvesting terms from intensive orchard; 1.7 higher level in the mass harvested apples and 1.4 higher level in the fruits of late harvesting from traditional orchard
