Endogenous hormone levels in habituated nucellar Citrus callus during the initial stages of regeneration
(2001-01)
Embryogenic nucellar callus cultures of different Citrus species and cultivars growing in hormone-free medium were transferred to medium containing either sucrose or glycerol as the only carbohydrate source. Glycerol has ...
Micropropagación de Guadua angustifolia Kunth a partir de explantes nodales
(2004)
Se evaluó el efecto de diferentes estrategias de desinfección, así como de varias concentraciones de la citoquinina 6-bencilamino purina (BAP) en el medio de cultivo, sobre el establecimiento y desarrollo in vitro de ...
Evolution of endogenous hormone concentration in embryogenic cultures of carrot during early expression of somatic embryogenesis
(2004-09)
Embryogenic callus and suspension cultures of carrot (Daucus carota L., cv. Nantaise), growing on/in medium including 1 mg/l 2,4-dichlorophenoxy acetic acid (2,4-D), were transferred to medium with or without this plant ...
Caracterización anatómica ultraestructural de las variantes “Atlántica”, “Sur” y “Cebolla” del bambú, Guadua angustifolia (Poaceae: Bambusoideae), en Costa Rica
(2006-08-20)
We present an ultrastructural characterization of three variants or “forms” of Guadua angustifolia
and of the closely related Guadua sp., from Costa Rican populations. Their ultrastructure is similar. Differences are: ...
Ultraestructura del bambú Guadua amplexifolia (Poaceaea: Bambusoideae) presente en Costa Rica

Se estudió la ultraestructura anatómica de la lámina y la vaina de la hoja, así como de la bráctea del culmo, de Guadua angustifolia var. Bicolor, por medio de los micros-copio electrónico de barrido. Se encontraron ...
Response of Endogenous Hormone Concentrations to Two Floral Inductive Treatments, viz. KNO3 and PBZ, in Mango cv. ‘Tommy Atkins’ Growing Under Tropical Conditions
(2012-07-20)
Floral induction (FI) has been intensively studied in mango, more under sub-tropical than under tropical environments. Decreases in temperature below 20 °C, which is common in sub-tropical regions but seldom occurs in many ...
Effect of hydrogen cyanamide on the endogenous hormonal content of pea seedlings (Pisum sativum L.)
Efeito da cianamida hidrogenada sobre o conteúdo de hormônios endógenos em plântulas de ervilha (Pisum sativum L.)
(2008)
Hydrogen cyanamide (HC) has been used to break bud and seed dormancy and to improve rooting in several species, responses usually associated with the action of plant hormones. However, very few studies have measured ...
