Effects of different hormones and media on cutting propagation in black currant

In order to improve quality of seedling breeding in black currant, taking the two varieties of ‘Black Wind'and ‘black Browder' as test materials, effects of different treatments on cutting propagation in black currant were researched through softwood cutting and hardwood cutting tests, including different parts of branches(upper, middle and lower), different media(sand, vermiculite, sand + vermiculite) and different types(IBA, NAA, ABT) and concentrations(100, 200, 300 mg/kg) of hormone treatments. The results showed that the lower softwood cutting had the highest rooting rate; the mixed medium of sand and vermiculite was suitable for hardwood cutting in black currant of, and rooting rate could reach 81% in the medium; Rooting rates of 200 mg/kg hormone treatments were the highest in each hormone concentration treatment, and rooting rate reached 82% in 200 mg/kg ABT treatment, but when hormone concentration was increased to 300 mg/kg, the root rate was decreased.
