التوصيف المظهري لبعض طرز الخوخ البري Prunus cerasia Blanche المنتشرة في الساحل السوري
Abstract
This research was conducted during 2016-2017 on (42) wild trees of Prunus cerasia Blanche prevailing in the Syrian coast. Twenty-five morphological traits of leaves, fruits, stones and flowers were studied on (12) sites in Lattakia and Tartous, 27-986 m above sea level. The results showed obvious morphological differences between the studied trees according to morphological affinity tree at 33.65%. The P. cerasia trees were distributed to four groups: (A) included 17 trees with morphological variation of 27%, (B) included 9 trees with morphological variation of 20%, (C) included 6 trees with morphological variation of 24.82%, and (D) included 10 trees with morphological variation of 24.56%. The trees of each group constituted a morphologically independent type with exact morphological identity.
نفذ هذا البحث خلال عامي 2016 -2017 على (42) شجيرة تابعة لنوع الخوخ Prunus cerasia Blanche المنتشرة برياً في الساحل السوري.
تمت دراسة (25) صفة مظهرية لأوراق وثمار ونوى وأزهار شجيرات النوع المدروس في (12) موقع من محافظتي اللاذقية وطرطوس وعلى ارتفاع (27-986 م) عن سطح البحر. أظهرت النتائج وجود اختلافات مظهرية واضحة بين الشجيرات المدروسة وفقاً لشجرة القرابة المظهرية وصلت نسبتها إلى (33.65%)؛ إذ توزعت شجيرات الخوخ البري ضمن أربع مجموعات، ضمت المجموعة الأولى (A) أكبر عدد من الشجيرات المدروسة (17 شجيرة) وبنسبة تباين مظهري بلغت نحو 27%، وضمت المجموعة الثانية (B) (9 شجيرات) بنسبة تباين لم تتجاوز 20%، وضمت المجموعة الثالثة (C) (6 شجيرات) بنسبة تباين 24.82%، في حين ضمت المجموعة الرابعة
(D) (10 شجيرات) بنسبة تباين 24.56%؛ إذ شكلت شجيرات كل مجموعة طرازاً مظهرياً مستقلاً حددت هويته المظهرية بدقة.
