Trials were conducted using paclobutrazol (PP333) either as a foliar application or a soil drench to improve berry set and yield of ‘Roumi Red’ grapes (Vitis vinifera L.). Concentrations of 100 and 250 ppm (foliar applications) and 2 ml/vine as a ground application had no effect on either chlorophyll and carotenoid leaf content or physical and chemical properties of berries, other than cluster weight and number of berries/cluster, which increased significantly. Concentrations of 1000, 1500, and 2000 ppm and 4 ml/vine reduced shoot and internode length as well as °Brix, whereas physical and chemical properties of berries, bud fertility, chlorophyll, and carotenoid leaf content were increased. A carry-over effect was noticed the year following the year of application with concentrations of 750 ppm and 3 ml/vine or higher. Chemical name used: β[(4-chlorophenyl)methyl]-α-(1,1-dimethylethyl)-1H-1,2,4-triazole-1-ethanol (paclobutrazol).

In the paper “Rest Completion Prediction Model for ‘Starkrimson Delicious’ Apples” by Assem D. Shaltout and C.R. Unrath [J. Amer. Soc. Hort. Sci. 108(6):959–961, 1983], there is an error on page 959 in footnote y for Table 6. The correct version of the footnote is as follows: , where Tm = 4.4°C if temperature < 4.4°C; Tm = 25°C if the temperature is > 25°C.
