THE INFLUENCE OF THE LENGTH OF HARDWOOD CUTTINGS ON THE PROPAGATION OF BLACKCURANT (RIBES NIGRUM) |
| Authors: | H. Wainwright, H.Y. Hawkes |
| Abstract:
Four cultivars of blackcurrant ("Baldwin", "Jet", "Ben Lomond" and "Ben Nevis") were propagated using hardwood cuttings of 5,10,15 and 20 cm in length. The cuttings were planted in March and rooted cuttings were harvested the following November. The length of cuttings did significantly influence the percentage that rooted, the amount of new extension growth, the mean number of new shoots produced and the dry weight of the new growth. There were also differences between the cultivars when considering the above parameters but with no character were there any interactions between cutting length and cultivar. The results suggest that cutting length could be reduced from the recommended 20cm length to 15cm without significant loss of productivity. | |
