Effect of Timing and Severity of Leaf Removal on Some Chemical and Physical Fruit Composition of SALTANI Grapevines

Abstract

The investigation was conducted to study the Effect of timing and severity of leaf removal on some chemical and physical fruit composition in two severity level 30% and 50% , two time pea size and variation on some physical and chemical characteristics for grape .To the best time and level for removal .The result shown ,the growth curve is double sigmoid curve reach 13 week after full plume , the depressed period reach 7-10 day . The change leaf area was linearity during growth season. The removal effect is significant on increase cluster weight in time pea size and variation but no noticed significant different in two level 30% and 50% , the removal increased weight and size fruit ,TSS, total and reducing sugar in level 30% and pea size, the acidity increase significant in two level 30% and 50% but no noticed significant different in twice time pea size and variation..
