Ação de extratos vegetais e fitoreguladores na organogênese de Begonia rex

Petiole explants of Begonia rex were cultured on basal medium (MURASHIGE & SKOOG, 1962). The medium was suplemented with naphthalene acetic acid (0.01; 0.1 and 0.5 mg/I) and kinetin ( 0.1; 0.2; 0.5 and 1.0 mg/I). In these experiments, were as also used coconut water (15% and 20%) or potato e...

Description
Summary:Petiole explants of Begonia rex were cultured on basal medium (MURASHIGE & SKOOG, 1962). The medium was suplemented with naphthalene acetic acid (0.01; 0.1 and 0.5 mg/I) and kinetin ( 0.1; 0.2; 0.5 and 1.0 mg/I). In these experiments, were as also used coconut water (15% and 20%) or potato extract ( 15% and 20%). Buds were formed in several treatments, but the best combination was coconut water 0.01 mg/L NAA and 0.1 mg/I KIN. Whole plants (40% of the explants) were obtained when was added coconut water . The optimal combination for plant regeneration (100%) was 0.01 mg/I NAA plus 0.1 mg/I KIN.
