تأثير مستخلصات أشجار أكاسيا ساليجنا Acacia saligna على إنبات نباتي القمح، و الشعير بمنطقة الجبل الآخضر

الملخص EN

Acacia saligna is an invasive species and abnormally distribution outside its native habitat.

This leads to an imbalance in the diversity of local species plants and crops because of marked spread in Al- Jabal Al-Akhdar region.

The study was aimed to examine the negative effects of aqueous extracts of Acacia saligna leaves, bark, and seeds at a concentration of (10, 20, 40, and 60%) on the germination of wheat and barley seeds.

The results illustrated that there were highly significant differences in germination percentage reduction.

Also, the results of the seed extracts showed a greater inhibitory rate compared to the leaves and bark extracts.

It was also noted that all extracts with their concentrations led to a reduction in the root and shoot lengths of both plants.

The 60% concentration was the most toxic in inhibiting all the studied traits.

The wheat plant is the most sensitive to aqueous extracts.
