ABSTRACT
The cluster samples from the grape gardens and unaffected by tylose from the same locations, were collected from Sangali, Solapur and Pune region revealed that the tylose on main stem of cluster affect the imbalance of nutrients in rachis and pedicel. The concentration of N and K was found to be increased and Ca and Mg decrease considerably. The imbalance of these nutrients leads to formation of tyloses. A field experiment was also conducted for two consecutive seasons to investigate the effect of spraying of different chemicals from veraison to maturation on controlling the tylose formation. It was revealed that spraying of magnesium sulphate (0.5 %) in combination with boron (0.1 %) and molybdenum (0.01 %) reduced the tyloses significantly (9.20 %) as against (32.60 %) in control.
Key words :
Grapes, pedicel, rachis, tyloses, Thompson Seedless, Vitis vinifera.
