SOME CULTURAL PRACTICES TO HASTEN YIELD AND CLUSTER CHARACTERISTICS OF RED ROUMI GRAPE.

Abstract
This study was undertaken during the seasons 2004 and 2005 to evaluate the effect of removing 1/3 flower cluster length (about 10 cm of cluster length) at full bloom or trunk girdling immediately after berry set each alone or in combination under bud load of 60 or 80 eyes/vine of Red Roumi grapevine .The data reveal that removing 1/3 flower cluster length or trunk girdling significantly increased the yield per vine. Yet, combined treatment (removing 1/3 flower length with trunk girdling) gave a higher significant yield than those obtained from each alone or the control. The increment in yield was almost higher in vines which having 80 eyes/vine. With regard to effect of cluster shape and berry quality, the data also presented that shortening cluster with trunk girdling gave a higher cluster weight than vine which having 60 eyes/vine. The increase of cluster weight may be due to this treatment produced a higher berry weight and size .Also, combined treatment with removing 1/3 flower cluster length with trunk girdling under 60 eyes/vine increased SSC and SSC/acid ratio and anthocyanin content so, improved the berry quality of the cluster.
