تأثير شدة التقليم في إنتاج أشجار التفاح في نظام الزراعة الكثيف
Abstract
تم إجراء البحث على أشجار التفاح بعمر (10) سنوات مزروعة في منطقة الكفرون التابعة لمحافظة طرطوس, زراعة كثيفة والعائدة للصنفين Golden delicious و Starking delicious بهدف دراسة تأثير شدة التقليم الشتوي في إنتاج الأشجار خلال موسم (2012 – 2013) و كانت النتائج على الشكل التالي :
1- لم يلاحظ وجود أي تأثير لمعاملات التقليم المدروسة في محتوى الثمار من المواد الصلبة الذائبة الكلية و السكريات الكلية .
2- تفوقت معاملات التقليم على معاملة الشاهد في نسبة العقد في كلا الصنفين ففي الصنف Golden delicious بلغت قيمتها (40.75 – 33.20%) في معاملتي التقليم الشديد و الشاهد على التوالي, و في الصنف Starking delicious بلغت ( 29.80 – 26.30%) في معاملتي التقليم الشديد و الشاهد على التوالي, كما تفوقت معاملات التقليم على معاملة الشاهد في وزن الثمرة في كلا الصنفين ففي الصنف Golden delicious بلغت قيمتها ( 140.50 – 129.30) غ في معاملتي التقليم الشديد و الشاهد على التوالي و في الصنف Starking delicious بلغت ( 151.70 – 139.90) في معاملتي التقليم الشديد و الشاهد على التوالي .
3- أدت معاملات التقليم إلى تخفيض محتواها من الحموضة الكلية .
4- أدت معاملات التقليم إلى انخفاض إنتاج أشجار التفاح و كان مقدار الانخفاض في الصنف Golden delicious (14.19) % بينما وصل إلى (19.72 ) % في أشجار الصنف Starking delicious مقارنة مع الشاهد .
This research was carried out on (10) years old ( Golden delicious & Starking delicious ) apple trees . which were planted in AlKafron region – Tartus Governorate under
1- There wasn't any effect of pruning treatments on total soluble solids content or total sugars .
2- Pruning treatments were better than control in fruit set in both cultivars , in Golden delicious, were ( 40.75 - 33.20 %) in severe Pruning and control, respectively , in starking delicious , were (31.35 – 26.30 %) in severe Pruning and control, respectively , and Pruning treatments were better than control in average of weight fruit in both cultivars , in Golden delicious, were (140.50-129.30) g in severe Pruning and control, respectively , in starking delicious , were (151.70-139.90) g in severe Pruning and control, respectively .
3- Pruning treatments resulted to reduce total acidity content .
4- Pruning treatments resulted to reduce yield by (14.19-19.72)% in Golden delicious and starking delicious , respectively , comparing with control .
