Grape yield and quality of the grapevine cultivar Limberger treated with plant growth regulators
Todic, S.R.(Faculty of Agriculture, Belgrade - Zemun (Serbia and Montenegro))
The effects of foliar application of paclobutrasol (PK), chlorcholinechloride (CC) and gibberellic (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 weighht and grape yield per square meter 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 - 100 mg/l no significant increase in yield was found, whilst sugar content of must was significantly increased.
