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...
The degradation of the Andean cloud forest raises strong biological conservation issues and threatens the sustainability of a crucial water resource. The idea that nurse-based restoration can accelerate the recovery of these forests is underexplored, despite its promise as a restoration technique. Recent conceptual models predict that facilitation ...
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...

L'influence de différents régimes trophiques sur la capacité de survie et la longévité d'une espèce zoophytophage (Macrolophus pygmaeus Rambur ; Hemiptera : Miridae) a été étudiée. Les différentes sources trophiques, présentées seules ou en combinaison étaient de l'eau libre, une plante (tabac), et une proie (oeufs d’Ephestia kuehniella Zeller ; Le...

Higher caffeine content and cup beverage bitterness considerably depreciated the commercial value of Coffea canephora Pierre (CAN) compared with C. arabica L (ARA). Wild caffeine-free species like C. pseudozanguebariae Bridson (PSE) offer the opportunity to produce new CAN varieties containing little or no caffeine. F1 plants resulting from a PSE ×...
