HIERONYMA ALCHORNEOIDES PDF

Pilon Hieronyma alchorneoides Euphorbiaceae is one of the native timber species of Costa Rica best adapted to conditions of open plantation. Due to its growth characteristics and variety of uses, the demand for planting material has increased. This species presents serious problems with seed reproduction; it is a dioecious, the fruit production varies over time and between trees, trees produce large quantities of fruit but are heavily predated by different birds. In recent years, the percentage of damaged fruit has increased due to wasps and the seeds lose their ability to germinate within days of harvest recalcitrant. These factors make micropropagation an attractive option for mass propagation of the species.
