Embryogenic calli were initiated from leaflet explants on Murashige and Skoog medium supplemented with picloram alone or picloram in combination with 6-benzylaminopurine. Leaflets of accession A6138 induced the highest percentage of somatic embryos in media composed of 10 mg.dm(-3) and 15 mg.dm(-3) picloram. In contrast, 5 mg.dm(-3) picloram with 0.1 mg.dm(-3) 6-benzylaminopurine was one of the most effective combinations in accession AF385. MS medium supplemented with 2 g.dm(-3) activated charcoal (AC) used for 30 days was the most effective for embryo maturation. After 20 days of culture on MS medium devoid of growth regulators, 6 % of embryos converted into plantlets in accession A6138. 收起
