RESEARCH ON THE USE OF MULBERRY VITROPLANTS IN ORDER TO PRACTICE A SUSTAINABLE AGRICULTURE.

The conservation of sericultural vegetative genetic resources is a permanent concern in the sericulture field, being known that the mulberry leaf is the only source of food for the silkworm Bombyx mori L. These sericultural vegetal genetic resources are mainly used to obtain planting material used for establishment the mulberry plantations, but also for the mulberry improvement program and the establishing of the phytoremediation potential of mulberry plants. The research carried out for the preliminary testing in laboratory of in vitro multiplication potential of some mulberry varieties have highlighted the possibility of using the biotechnologies of tissue cultures, meristems and organs for testing the phytoremediation potential of mulberry plants with sericultural destination. Thus, a planting material was produced, consisting of mulberry vitroplants colonized with vesicular-arbuscular endomycorrhizae, which keep the genetic characteristics of parental forms, but present superior bioproductive parameters and physiological tolerance on soils contaminated with lead.
