FORCING AND ROOTING DORMANT SINGLE NODE CUTTINGS OF BLACKCURRANT |

| Abstract:
The rooting percentage of single node blackcurrant cuttings between October and January is low. Bud break is linked to rooting in blackcurrant hardwood cuttings and treatments to break bud dormancy were applied and their influence on rooting was recorded. Bud scale removal was an effective way to force buds to grow and allow cuttings to root, though the removal of the scales is an intricate and time consuming operation. Soaking the cuttings for one hour in KNO3 increased bud break and rooting of the cuttings. A one hour KNO3 soaking period, when compared with two, four and eight hours gave an equal or a more advanced stage of bud development and a greater number of roots. Soaking the cuttings in distilled water also gave similar results to the one soak in KNO3. There were significant differences when cuttings were soaked in different nitrate salts (Ca(NO3)2, KNO3, Mg(NO3)2, NH4NO3, NaNO3 and Za(NO3)2) though KNO3 was a nitrate salt which gave results similar to the most advanced bud break and largest number of roots. | |
