Abstract

          This research amied to study heat requirement of Crimson Seedless grapevines and its relationship with growth and yield properties during 2009 and 2010 seasons in two different regions, the first at El-Santa Gharbia in clay soil at Middle Nile Delta and the other in El-Nobaria Behyra, new reclamation land. Planting distance was 1.5 X 3.0 m between the vines and the rows, the vines supported by Gable trellis system with vine load was 120 buds/vine. Number of cluster was adjusted to 28 clusters per vine. The resulted from this study showed that, grapevine grown under El-Santa Gharbia delayed budburst, full bloom, and harvest date than those grown under El-Nobaria Behyra condition. The data also reveal that, leaf area, shoot length, pruning weight, berry coloration and soluble solid content was higher under Gharbia region. Since, from the available data were recommended to planting Crimson Seedless grape under Delta region than under desert condition in order to obtained clusters with
good quality and increased the income (L.E) for the Farmers.
