| Popis: | The effects of naphthaleneacetic acid (NAA) and indolebutyric acid (IBA) on rooting, root quality, and budbreak of Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stem cuttings were studied. Between 1 and 100 him, NAA was more effective than IBA in stimulating rooting. Regression analysis indicated that the highest rooting response to NAA was centered on 7.4 mM, whereas 100 mM IBA, the highest concentration tested, was the most effective. NAA concentration significantly affected budbreak percentage. Root quality was weak, but not significantly affected by auxin concentration. |
