تمت دراسة تأثير بعض عمليات التقليم الصيفي (الأخضر) في نمو صنفي العنب المحليين حلواني و بلدي التابعين للنوع .Vitis vinifera L, و إنتاجهما أُجريت الدراسة في مزرعة خاصة في منطقة القدموس خلال العام 2012, على شجيرات عنب مرباة على أسلاك من الصنفين المذكورين, و شملت 7 معاملات (1- شاهد, 2- تفريد, 3- تفريد و قصف, 4- تفريد و قصف و تفريع, 5- تفريد و تفريع, 6- تفريد و تفريع و توريق, 7- تفريد و توريق).
أظهرت النتائج تأثير عملية القصف في تحسين وزن العنقود و الثمرة و ذلك نتيجة تأثيرها في تحسين نسبة العقد الأمر الذي انعكس إيجاباً على إنتاج الشجيرة و على الصنفين موضوع الدراسة, كما حسنت عملية التفريد فقط نسبة المواد الصلبة الذائبة الكلية بعكس بقية العمليات المنفذة, كما أدت عمليتا القصف و التفريع دوراً في زيادة نسبة الحموضة الكلية.
This research was carried out to study the effect of summer pruning on the growth and production of two grape varieties Vitis vivifera L. Halwani and Baladdi. The study was conducted in Kadmous during 2012 growing season on two varieties of grape trees reared on wiredraw. Seven treatments were used: 1- control, 2- shoot thinning, 3- shoot thinning and hedging, 4- shoot thinning and axillary shoot removal, 5- shoot thinning and axillary shoot removal, 6- shoot thinning and axillary shoot removal and leaf removal, 7- shoot thinning and leaf removal.
Results show that hedging improves weight of cluster and berry due to the increase in fruit set percentage which leads to an increase in grape production. Shoot thinning increases TSS yet other processes have negative effects: the hedging process increases acid titration in the Baladdi cultivar but in the Halwani cultivar hedging and axillary shoot removal increases acid titration.
