Abstract: | Conclusion In the area of cell and tissue physiology, the grape vine has been a major reference material. As with all woody perennials, in vitro technologies are relatively delicate. Nevertheless, remarkable progress has produced a situation where, during the past ten years, practical application of results from in vitro work has been envisaged. Reciprocal understanding has yet to be established between scientists developing micropropagation (multiplication with conformity to type) and those using in vitro methods for variety improvement (multiplication for novelty of type). I am convinced that the future should not see one of these objectives dominating the other. On the contrary, certain technologies should be developed to ensure a framework for conformity of propagation and others to obtain greater variability with the goal of plant improvement. This will render effective the two applications considered. |
