Abstract

In order to evaluate the effects of nutrition, IRRIGATION regimes and HARVEST TIME on the QUALITY and shelf life of RED DELICIOUS APPLE (Malus domestic), this research was carried out in Uromieh region during two years (2000-2001). Treatments were including IRRIGATION (full IRRIGATION, regulated deficit and removal IRRIGATION two weeks before harvest), HARVEST TIME (138, 145 and 152 days after full bloom) and nutrition control (foliar spraying of CaCl2 (1%) and spray and dipping of fruits in CaCl2 solution (4%) at HARVEST TIME). All treatments were stored for 6 months at 0o C and 85- 90% humidity. Samples were analyzed for firmness, TSS, pH, TA, density, juiciness, medium weight and macro elements in HARVEST TIME and also every 30 days firmness, TSS, pH, TA and macro element were measured. The result showed that the effect of HARVEST TIME (in 1% level), interaction between nutrition and IRRIGATION and harvest-irrigation (in 5% level) on firmness were significant. Effect of HARVEST TIME and interaction between 3 treatments (in 1% level) on TSS was significant. However, HARVEST TIME showd a significant effect on pH (in 5% level) and TA (in 1% level). Effect of HARVEST TIME and IRRIGATION on the medium weight and the juiciness of fruits (in 1% level) and interaction between IRRIGATION and harvest (in 5% level) were significant. However, their effect on density was not significant. HARVEST TIME and interaction between nutrition and HARVEST TIME, interaction between nutrition and IRRIGATION and interaction between three treatments on calcium content of fruits in 1% level was found the treatments to be significant. In general, overall QUALITY of fruits at the end of storage time was the same for all. In panel test scores, top number was related to the 4thnutrition treatment, second HARVEST TIME and second method of IRRIGATION. Therefore, it is recommended to harvest RED DELICIOUS APPLE 145 days after full bloom, to apply CaCl2 solution (1%) in spray method four times, to dip fruits in 4% solution for 10 minutes and to cut of IRRIGATION two weeks before harvest.
