Influence of Physiological Factors on Rooting Ability of Plum Root- stocks' Hardwood Cuttings

摘要

The physiological basis of rooting is well studied, it is known that certain substances formed in the plant are related to rooting, but their exact chemical composition, way of action, and the relation among them have not been cleared yet. Our aim wasto examine the phe-nological status of the mother plant, the environmental conditions, the biochemical features of the cutting material at the time of collection, and the state of dor-mancy of buds. We also tried to discover correlations between these factors and rooting potential of cuttings, and also among the factors. The conclusion is that the complex process of rooting can be influenced in direct or indirect ways by the factors under investigation. The possible connections between rooting and thefactors examined are shown in a figure.
