تم جمع و دراسة /5/ أنواع من جنس القبأ Poa التابع للفصيلة الكلئية Poaceae في محافظة اللاذقية هي : P. annua ، P.infirma ، P. pratensis ، P. bulbosa، P. nemoralis .
تضمنت الدراسة وضع قاعدة بيانات للصفات الشكلية التي شملت الشكل العام للنبات، الأوراق، اللسين، تركيب النورة ، السنيبلة، الزهرة، و الصفات الشكلية الدقيقة التي شملت بدورها تركيب بشرة السطح السفلي للورقة و اختلاف تركيب المنطقتين الضلعية و بين الضلعية لدى لأنواع الخمسة، بالإضافة إلى دراسة حبات الطلع و التي أوضحت تجانسها شكلياً مع اختلاف بسيط في الأبعاد، ثم رُبطت نتائج قاعدة البيانات الناتجة باستخدام البرنامج الإحصائي Statistica للحصول على مخطط شجري dendrogram يوضح درجة القرابة بين الأنواع الخمسة ، أظهر المخطط تقارب النوعين الحوليين P. annua ، P.infirma لارتباطهما معاً بعنقود و انفراد كل نوع من الأنواع الثلاثة الأخرى المعمرة بعنقود و كان النوع الأقرب للنوعين الحوليين هو P. nemoralis .
Five species of the genus Poa L. from (Poaceae) were collected and studied in
Lattakia, they are : P. annua ، P.infirma ، P. pratensis ، P. bulbosa ،P. nemoralis.
This study put data base of the morphological features which included : habit, leaves,
ligule, the structure of the inflorescence , spikelet, floret, micro-morphological
characteristics which contained the epidermal structure of abaxial leaf surface, and the
difference between costal and inter-costal zones of the 5 species, studying of pollen grain
clarified the similarity in shape but there was a simple difference in measurements . Then ,
data from micro and macro morphological study were used to made a Dendrogram by
using Statistica . The dendrogram showed the linkage of two annual species P. annua ،
P.infirma in a cluster , every one of three another species had his specific cluster , P.
nemoralis was closer to the annual species .
