EFFECT OF FOLIAR APPLICATION WITH GROWTH REGULATOR KT-30 AND CHELATED – IRON ON QUANTITATIVE AND QUALITATIVE CHARACTERISTICS OF THE GRAPE , Vitis vinifera. L .

Abstract

The research was carried out in the vineyard of the province Diyala during 2009 on the grape vine cv. AL – Kamali which is a good table – grape . The work was done to investigate the effect of fertilizing with Fe+2 - EDTA at levels 0 , 100 gm / vine and spraying with growth regulator KT – 30 at four levels ( 0 , 0.25 , 0.5 and 1 ml . litter-1 and their combinations on quantitative and qualitative character of grape vine cv. AL – Kamali . Results showed that the grape vines significant responded to Fe+2 – EDTA alone or in combination with growth regulator , there were a significant differences in leaves area , chlorophyll content , fruit set percentage , total yield / vine , berry weight , berry size and cluster weight . There were no significant effects of iron on the total soluble solids % . or the spray with growth regulator on the weight , berry size , and cluster weight , While treatment with 0.25 ml . L-1 spray of G . R . resulted in a significant increase in yield (12.23 Kg / vine ) and leaves area . The spraying of growth regulator ( 1 ml . L-1 ) showed a significant value of chlorophyll percentage and T . S . S . while the concentration ( 0.5 ml . L-1 ) gave a significant increase in the number of berry in cluster ( fruit – set ) and showed significant combination between fertilized treatment with iron and sprayed with growth regulator in most of investigated characters .
