N2 - In 2008, in Central Italy, a low dosage of CPPU solution, 4 μL L -1 (6 hL/ha), was sprayed on the canopy of vines of 'Hayward' kiwifruit, at the "break of sepals", about one week before anthesis, to study its effects on fruit weight/size and on qualitative and nutritional characteristics. At harvest, CPPU, with respect to control, significantly increased the fresh weight by about 12% (+ 12.6 g fruit-1) and consequently the yield per vine, without affecting fruit shape, firmness, dry matter (%), total soluble solids, glucose, fructose, sucrose, starch, citrate, malate, vitamin C and soluble and insoluble oxalic acid. After 3 months of storage, CPPU-treated kiwifruits and the control fruit showed no difference in dry matter content, fruit firmness and total soluble solids. The results indicate that a low dosage of CPPU applied in pre-anthesis can improve fruit weight/size without any negative effect on fruit qualitative and nutritional characteristics.
