Delayed ripening of Shiraz berries after treatment with Ethrel. Changes in TSS, measured as degrees Brix, in field grown Shiraz berries treated (A) once in 2011 (20 days pre-veraison) or (C) twice in 2012 (8 and 1 days pre-veraison) with 300 μL L^-1 Ethrel in 0.1% (v/v) Chemwet 1000 or 0.1% (v/v) Chemwet 1000 (Control). The same berry samples were used to measure changes in berry weight in (B) the 2011 and (D) the 2012 samples. Control, closed circles with solid lines; Ethrel, closed triangles with dashed line. All data represent means ± SE (n = 3). Asterisks indicate significant differences of the mean values of Ethrel-treated samples from the mean values of Control samples as determined with Student’s t-test (*p < 0.05, **p < 0.01).
