Develop principles for optimising the micropropagation of HNS by investigating the effects of shoot development in... - HH1202SHN

Description
Develop principles for optimising the micropropagation of HNS by investigating the effects of shoot development in vivo and in vitro on rooting potential.
Objective
Propagation by cuttings is the most widely used method employed by UK nurserymen for the production of ornamental shrubs and some trees, with an estimated 200 million cuttings used each year. Success at this critical stage is central to cost-effective production of high quality plants, especially of more difficult and hence premium-attracting varieties.
This project complements HH1201SHN by moving the search for improved understanding of propagtion physiology into the tissue culture laboratory, thereby avoiding the interference from weather, season and other plant processes, without ignoring their practical importance in the practical propagation that this project seeks to improve. In particular, the objective is to understand at tissue level the mechanism determining competence to root and the root initiation process.
Nurserymen will benefit generally through improved techniques for stock plant management and cutting handling, and specifically by their ability to produce cuttings with high rooting potential against the present situation that even in optimal propagtion environments cuttings of many species callus but fail to root. Improved understanding will feed through via HDC-funded projects to increase the product range and plant quality, and reduce production time and wastage in UK nurseries.
