Abstract:
... The morphology, anatomy and physiology of in vitro cultured plants do not facilitate survival when transferred to dynamic ex vitro environments. The benefits of a micropropagation system completely depend on successful transfer of in vitro plants to septic ex vitro conditions. Avocado (Persea americana Mill.) is a luxurious tropical fruit becoming very popular with increasing consumption around th ...

Abstract:
... The umbuzeiro (Spondias tuberosa Arruda) is a native fruit tree of Caatinga and has great economic importance. Its fruits are collected extractivistically due to lack of commercial plantations. Furthermore, the seeds have physical dormancy, which reduces germination rates. However, tissue culture can be used to overcome such problems by excision and in vitro culture of embryos with gibberellin. Th ...

Abstract:
... Microcutting is a repeated process in which in vitro shoots develop new shoots from axillary meristems. In Hevea, this system works for seedlings, but not for shoots derived from mature trees. As for a lot of other tree species, one of the consequences of aging (losing juvenility) is poor in vitro growth and multiplication and the lack of a proper geotropic (tap)root system. In rubber tree, somati ...
