Vegetative Propagation , of , (Lamb.) Hook,20 years (9). Today’s forests are largely plant associations which are only partially accessible to genetic control and agricultural practices. Among species with a great potential for productivity, the gymnosperms are well represented. So far about 20 of them have been studied for their . performan

Conifer Micropropagation : Applied Research and Commercial Aspects,rnamental species were propagated by rooted cuttings. However, evolution of vegetative multiplication techniques of woody plants has altered the situation. Today, numerous species of coniferous trees are propagated by rooted cuttings, among them: . sp., . etc. Often the starting material is selected
