为了提高黑穗醋栗苗木繁育质量，分别以‘黑风’和‘黑布劳德’两个优良品种为试验材料，就枝条的不同部位（上部、中部和下部）、不同基质（河沙、蛭石、河沙＋蛭石）和不同种类（IBA、NAA、ABT）、不同浓度（100、200、300 mg/kg）的激素处理对黑穗醋栗扦插生根的影响情况进行了嫩枝扦插和硬枝扦插试验。结果表明：以下部嫩枝扦插的生根率为最高；河沙与蛭石的混合基质适用于黑穗醋栗的硬枝扦插，以此混合基质扦插的生根率可达81%；每种激素处理的生根率，均以200 mg/kg浓度处理的为最高，其中以200 mg/kg的ABT处理的生根率达到82%，而当激素浓度升高到300 mg/kg时，生根率反而下降。%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.
