    Utilization of forest bıodıversıty: Rewards of ceratonıa sılıqua l. For apıs mellifera
    (Uludağ Üniversitesi, 2012) Maha, Syouf; Haddad, Nizar
    Plant community of Ceratonia siliqua L. at Wasfi Al-Tal forest reserve was investigated during 26 September to 23 December 2004 to asses the utilization of Ceratonia siliqua L (Carob) for Apis mellifera (Honey bee). Nectar production rate was measured by emptying flowers, covering them for 24 hours with nylon mesh bags, and then sampling their nectar contents. The Ceratonia siliqua L. plant showed good results regarding the nectar volume and concentration and there was good honey bee visitation for pollen and nectar. Male trees were higher than the female ones regarding nectar volume and concentration, the mean volume for male trees was 17.4ml±9.7sd whereas, for the female ones it was only 4.25ml±4.9sd. The mean volume for the nectar concentration for male trees was 63.97%± 10.19sd whereas, for the female ones it was only 29.25%±34 sd.
