دراسة التغيرات في المحتوى الكيميائي لبذور بعض أنواع جنس الجلبان البري (Lathyrus. spp) في عدة مواقع من منطقة الغاب

Abstract

This study aimed to analyze variations in the chemical composition of seeds from several wild Lathyrus species collected from different locations in the Al-Ghab region. The results revealed significant differences (p≤0.01) in the accumulation of sugars, phenolics, and proteins among the studied species across sites. The Toubani site showed the highest sugar content (51.5% in L. digitatus), while Mardash recorded peak protein levels (26.6% in L. hierosolymitanus). The species L. blepharicarpus exhibited marked site-specific sensitivity in phenolic accumulation (12.72% at Joubet Al-Za'rour versus 8.6% at Tamazah). Notably, Lathyrus species at Mardash demonstrated stable production of secondary metabolites despite harsh environmental conditions. These findings provide a scientific basis for crop improvement strategies and optimal utilization of these wild species as sources of protein and functional compounds under changing climatic conditions.
