The effects of foliar application of paclobutrasol (PK), chlorcholinechloride (CC) and gibberellic acid (GA3) on grape yield and quality of the grapevine cultivar Limberger were studied. PK and CC strongly inhibited shoot growth. The number of berries per bunch, bunch weight and grape yield per m2 were increased. At the same time, sugar content of must was either reduced (CC2000) or retained at the level of control (PK1000, CC1000). The GA150 treatment resulted in lower grape yield. At the concentration of GA3 100mg/l no significant increase in yield was found, whilst sugar content of must was significantly increased
