Meteorological Conditions and Productivity of vitis vinifera in Syria

Dr. Adham Jalab

(Received 16 / 1 / 2008. Accepted 22/4/ )

� ABSTRACT �

The results of this study clearly indicate that the average of vitis vinifera productivity

has decreased during the research period in Aleppo, Homs, and Sweida by (-2.0808,-0.1071,-2.488 kg/tree), respectively , and has increased in Hama by (0.3648 kg/tree). The effective thermal accumulation during the growing season of vitis vinifera in each area reaches ( 2863.6,2793.8,2539.8,2212.4 G.D.D.) in Hama, Aleppo, Homs and Sweida, respectively. The results of Trend have demonstrated an increase in the effective thermal accumulations during growing season of the grapes in Aleppo, Hama, and Homs, and a decrease in Sweida. Finally, the multi-slope equation has attributed the productivity of grapes to the four most important climatic conditions affecting grapes during the growing stages in each of the four areas.

Keywords: vitis vinifera( Grapes) , productivity, climaticl conditions, regression, correlation.
