OPPORTUNITIES FOR THE SELECTION OF VEGETATIVELY PROPAGATED CLONES WITHIN ORNAMENTAL TREE SPECIES NORMALLY PROPAGATED BY SEED |
| Authors: | B.H. Howard, H.R. Shepherd |
| Abstract:
Attempts to propagate various tree species by hardwood cuttings produced a general estimate of rooting differences between species. Little improvement in rooting was achieved by altering propagation conditions such as auxin concentration or wounding. Cuttings from bushes grown from individual seedlings of Tilia cordata differed greatly in their rooting ability, such characteristics being consistent between different years in many cases. Superior rooting forms should be sought among heterogeneous populations of seedlings, using a standard technique, as a prerequisite to developing improved propagation techniques for woody ornamental trees. | |
