BACKGROUND The pan-tropical genus Ardisia has more than 400 species and is of high horticultural and medicinal value. Due to overexploitation it is important to conserve the germplasm of this genus. OBJECTIVE To investigate the feasibility and methods of cryopreservation for long-term seed storage of three Ardisia species: A. elliptica Thunb., A. brunnescens Walker, and A. virens Kurz. METH...

Aquaculture is the major aquatic animal production segment. Problems like inbreeding depression, genetic drift, introgressive hybridization, etc. have been influencing of quality seeds negatively. Cryopreservation serves as a way-out for these problems and possible answer to produce genetically improved varieties. It has considered strategy conservation fish resources. gametes in vogue since 19...

ABSTRACT Aroeira-do-sertão is a Brazilian native species that has been widely explored. Thus, the population of this reduced and techniques for its preservation are essential, such as conservation seeds in liquid nitrogen (LN). The objective work was to evaluate different cryoprotectant solutions cryopreservation aroeira-do-sertão LN (-196 °C). treatments used were: control (7.5±1.5 °C); withou...

Advances in plant biotechnology provide new options for collection, multiplication and shortto long-term conservation of plant biodiversity, using in vitro culture techniques. Significant progress has been made for conserving endangered, rare, crop ornamental, medicinal and forest species, especially for non-orthodox seed and vegetatively propagated plants of temperate and tropical origin. Cell...

Many publications describe cryopreservation techniques but only a few studies have focused on the biochemical and physiological changes occurring in plants regenerated from seeds exposed to liquid nitrogen. This paper aims at describing the effect of common bean seed cryostorage on mineral nutrition of young plantlets. The following elements were measured on leaves of 10-dayold plantlets from n...

Abstract Palms ( Arecaceae ) contribute remarkable economic and environmental values to human life. However, many elite commercial palm species are becoming critically endangered demand immediate action preserve their genetic resources. Cryopreservation has established itself as the definitive in vitro conservation method for recalcitrant-seeded species, such those within . Progress this area m...

Cryopreservation of medicinal plants is an important tool for restoration of their potential to synthesize valuable secondary metabolites. Establishment of an efficient protocol requires detailed understanding of species/genotype-specific responses to changing external variables. The aim of this work was to study the genotype-dependent response of Hypericum perforatum L. shoot tips to different...
