دراسة تأثير بعض المعاملات في إنبات بذور الوزال الأسلي L. Spartium junceum و القندول الزغبي Calycotome villosa (Poiret)‎ Link. و تقدير أهميتهما العلفية

الملخص EN

The study was conducted in 2010 and 2011 in the laboratory and nursery of the Faculty of Agricultural )Aleppo University /Syria(, and aimed to investigate different treatments to overcome the dormancy of the hard-coated seeds for two species, Spartium junceum L.

and Calycotome villosa )Poiret( Link, to improve germination percentage and estimate their feeding values.

Four treatments were used: immersion in hot water at 100°C, mechanical scarification, concentered sulfuric acid )95% ( treatments for two different periods )10 and 20 minutes( and the control treatment.The results showed that all treatments have significantly increased the germination percentage in comparison with the control treatment for both species.

Thus, the applied treatments had enhancing effects on seed germination, indicating the presence of primary coat imposed dormancy in the studied seeds.

However, the percentage of germinations varies according to treatment and to species.

The immersion in hot water recorded the highest germination percentage for S.

junceum, which reached to 83.33% in comparison with 20% for the control treatment.

While the highest germination percentage for C.villosa was recorded under mechanical scarification and reached 65% in comparison with 1.67% for the control treatment.

The results indicated the necessity of pre-treatment for the seeds to increase the germination percentage.The chemical analysis of some biomass parts, which are consumable by livestock, showed the importance of their feeding values.

The content of protein reached reached 16.36% in S.

junceum, leaves and 20.

97% in C.villosaleaves, which indicated their feeding importance for livestock in natural forests
