Abstract: | Summary Green cuttings ofAlnus incana (L.) Moench, consisting of one internode and one leaf with its axillary bud, were easily rooted in aerated liquid substrate under growth-chamber conditions. In tests on material of up to 8 years-old, the age of the stock plants was shown to have no influence on rooting. Tap water or a diluted nutrient solution gave higher rooting percentages than a full strength nutrient solution. Root growth was most rapid in the diluted nutrient solution. Eight out of 9 clones ofA. incana gave a rooting percentage of 80–100% while one clone gave only 40%. Good rooting ofA. incana leafy cuttings, therefore, seems to be genetically controlled. |
