| Abstract:
In this paper we will review published research focused around the propagation and use of apricot rootstocks. Additionally, we will review current development of apricot rootstocks and suggest new avenues for rootstock research and what areas of development are required to satisfy needs of commercial apricot growers throughout the world. This is not an exhaustive review; specific adaptive characteristics that enable establishment and production under unique zonal ecologies will be emphasized, with rootstocks identified by their responses to biotic and environmental stresses. Desirable characteristics for which rootstocks are bred, selected, and propagated include: scion compatibility, adaptation for heavy and/or wet soils, pest and disease resistance, ease of propagation, control of vegetative vigor, effects on dormant season physiology of the scion, precocity, fruit quality, and productivity. In the future, rootstock selection and propagation must respond to demand for 'niche' fruits of specific characteristics, intensive production systems, mechanized harvest, and marginal site selection as worldwide consumer demand for apricots increases with improved apricot cultivars. Since rootstock development takes time a widely adapted rootstock incorporating most of the abovementioned characteristics would be preferred. | |
