<p>It is intended to propose a method of improving rooting ability of a cutting which is applicable to afforestation on a mass scale, can be easily controlled and enables improvement in rooting ability even in a hardly rooting arboreous plant. In a method of putting a cutting into a medium to give a rooted cutting, water containing at least one member selected from among carbon dioxide, oxygen, carbonate ion and hydrogencarbonate ion dissolved therein is supplied to the cutting to thereby promote the rooting of the cutting. The water is supplied by intermittently spraying or sprinkling. The arboreous plant is exemplified by those belonging to the genera Eucalyptus and Acacia.</p> |
