Traditional cocoa plantations in Ecuador are mostly composed of a complex mix of highly variable hybrid progenies, which has greatly reduced the population of native trees of the "Nacional" variety, to such a point that they are considered today as heading for extinction, which is increasingly worrying the international chocolate industry. Some yea...

The importance of seed provisioning in food security and nutrition, agricultural development and rural livelihoods, and agrobiodiversity and germplasm conservation is well accepted by policy makers, practitioners and researchers. The role of farmer seed networks is less well understood and yet is central to debates on current issues ranging from se...

This article aims to show the changes occurring during cryopreservation of embryos and plumules of coconut which are responsible of their death or survival. Embryos have been cryopreserved by preculture-dehydration for 24h, 28h, 30h, 34h, 38h and 48h on agar medium containing 600g/L of glucose combined with silica gel. The plumules were cryopreserv...

La gestion des ressources naturelles et des territoires peut prendre des formes diverses qui ont largement à voir avec les modes de pensée des acteurs qui les mettent en place. En prenant l’exemple de trois territoires contrastés (Parcs Naturels Régionaux du Luberon et du Queyras dans le sud de la France et Haut Atlas au Maroc), nous nous attachero...

Plumules excised from zygotic embryos through the largest representative diversity of four of the five different areas of coconut cash and food crops were used in a cryopreservation process using encapsulation-dehydration technique. Five accessions of coconut trees were used [Panama Tall (PNT/GPA), Brazilian Green Tall (BGD/NVB), Cameroon Red Dwarf...

Coconut is both socially and economically important crop in tropical and subtropical countries, thus the conservation of existing diversity of its germplasm is vital to maintain biodiversity, sustain crop production and utilisation of germplasm for crop improvement strategies. The recalcitrant storage behavior and large size of the coconut seed mak...
