Conteúdo: | In a previous paper different orchard treatments to improve and preserve storage quality of 'Shamouti' oranges were discussed.14 Additional studies confirmed the previous work. The treatment eventually divised consists of 20 ppm GA3, 18 ppm 2,4-D and 1% urea phosphate and potassium sulphate: it improves viability of oranges as determined by softness and deformation, juice components and rot percentage upon long storage. Seal packaging in high density polyethylene film further dramatically improves rheological properties, has little effect on fruit components, but increases rots, especially after long storage. These effects were verified at different locations. A climatic component of fruit viability could, nevertheless, be demonstrated. The citrus districts of Israel, a relatively small country, present surprisingly different conditions, due to interactions of coastal Mediterranean with interior semi-arid conditions influenced by the proximity of desert areas. 'Shamouti' oranges are extremely sensitive to semi-arid conditions, nevertheless internal quality was slightly better and rot percentage upon long storage much smaller in relatively drier areas. Rheological properties, however, were less satisfactory. A much wider climatic differentiation could be achieved with 'Marsh' seedless grapefruit grown in a much wider climatic range. Relatively drier interior areas (about 25 Km from the sea and shielded by mountain ranges) provided the best fruit for long storage.
