Desarrollo de cápsulas y germinación in vitro de Phragmipedium humboldtii, P. longifolium y P. percei
Slipper orchids belonging to the genus Phragmipedium (subfam. Cypripedioideae) are seriously threatened and therefore listed in Appendix I of CITES. Less research has been conducted in this genus than in others belonging ...
Carotenoids, carotenoid esters, and anthocyanins of yellow-, orange-, and red-peeled cashew apples (Anacardium occidentale L.)
Pigment profiles of yellow-, orange-, and red-peeled cashew (Anacardium occidentale L.) apples were investigated. Among 15 identified carotenoids and carotenoid esters, b-carotene, and b-cryptoxanthin palmitate were the ...
Ultraestructura del bambú Guadua angustifolia var. bicolor (Poaceae: Bambusoideae), presente en Costa Rica
Sections of leaf lamina, leaf sheath and branches of adult Guadua paniculata collected in Costa Rica, were studied ultrastructurally. Diagnostic ultrastructural characteristics include the cellular pattern of the adaxial ...
Challenges for Food and Nutrition Security in the Americas: Costa Rica and its commitment to sustainability
As a small nation with high biodiversity and an extensive system of protected areas, Costa Rica will face particular challenges regarding food security over the next few years. Thus, whatever development model the country ...
Hormonal status of maize initial explants and of the embryogenic and non-embryogenic callus cultures derived from them as related to morphogenesis in vitro
Endogenous hormone levels (indole-3-acetic acid [IAA], abscisic acid [ABA], gibberellins 1, 3 and 20 [GAs], zeatin/zeatin riboside [Z/ZR] and N6[Δ2-isopentenyl] adenine/N6[Δ2-isopentenyl] adenosine; [iP/iPA]) were analysed ...
Deposition Form and Bioaccessibility of Keto-carotenoids from Mamey Sapote (Pouteria sapota), Red Bell Pepper (Capsicum annuum), and Sockeye Salmon (Oncorhynchus nerka) Filet
The ultrastructure and carotenoid-bearing structures of mamey sapote (Pouteria sapota) chromoplasts were elucidated using light and transmission electron microscopy and compared to carotenoid deposition forms in red bell ...
Occurrence and characterisation of calcium oxalate crystals in stems and fruits of Hylocereus costaricensis and Selenicereus megalanthus (Cactaceae: Hylocereeae)
Detailed description about occurrence of calcium oxalate (CaOx) crystals in the edible vine cactus species Hylocereus costaricensis and Selenicereus megalanthus is scarce. Therefore, we evaluated and characterized the ...
Participation of plant hormones in determination and progression of somatic embryogenesis
In vitro culture protocols have been developed for many species, mainly using empirical approaches, to induce somatic embryogenesis from various explant types. However, the underlying biochemical mechanisms governing ...
