Main methods of artichoke multiplication and the role of seed reproduction
In Spain, multiplication is usually done by vegetative process, using cuttings, stumps or stalks, and the most important cultivar is LSQUOBlanca de Tudela'. The most interesting artichoke production period is autumn-winter. The principal drawback of vegetative multiplication is the presence of planting failures due to vascular and soil fungus. This article analyses the main systems of vegetative multiplication, by shoots, by cuttings, zueca or part of plant, ovolo and in vitro propagation of globe artichoke. At the same time another variation is presented: previously pre-sprouted cuttings in a heated chamber, this technique has never been imposed due to the high cost of implementing it. Cuttings pre-sprout in nursery, to reduce the number of dead plantings or low homogeneity. It was considered necessary to advance the pre-sprouting in the nursery for almost a month, thus allowing to start the harvest date earlier to the control. Early pre-sprouting in a pot was an interesting technique to reduce the problems of planting. This technique also improved early production, although it has the disadvantage of higher final cost of the plant. In numerous experiments with seed propagated artichoke, it has been found that there is plant material multiplied by seed that can be alternative to or complement the vegetative multiplication, existing cultivars of very good quality with green and violet heads.
