ISHS Acta Horticulturae 79: Symposium on Propagation and Raising of Nursery Stock
PRACTICE AND PROMISE OF MICROPROPAGATION OF WOODY SPECIES |
| Author: | A.J. Abbott |
| Abstract:
Many problems of propagation are peculiar to woody plants and attempts to solve them using tissue culture methods have been often disappointing. But the nature of the problems dictates that tissue cultures should find their place in practical nursery stock production. Three principle ways of propagating temperate trees and shrubs in aseptic culture, are from meristems and shoot tips, callus, and potentially from cell suspensions. Over fifty different species from nineteen families have now been propagated or have shown a propensity to regenerate from tissue cultures. The particular values of micro-propagation methods to the plant breeder are rapid multiplication, reduced risks of loss of stock, and reduced costs. The potential value of mutation breeding, haploid production and somatic hybridisation may also benefit the nursery trade in the future. | |
