Toledo, José M.Fisher, Myles J.[Physiological aspects of Andropogon gayanus and its compatibility with legumes]Physiological aspects of Andropogon gayanus and its compatibility with legumes

The effect of low phosphate supply (low P) was determined on the diurnal changes in the rate of carbon export, and on the contents of starch, sucrose, glucose, and fructose 2,6-bisphosphate (F2,6BP) in leaves. Low-P effects on the activities of a number of enzymes involved in starch and sucrose m...

El trabajo de campo se llevó a cabo en dos localidades de la costa Atlántica Colombiana, Riohacha en la Guajira, considerada como zona semi-arida y Santo Tomás Atlántico, como zona sub-húmeda. La respuesta a la humedad relativa se evaluó en diez cultivares, entre las 8 y las 13 horas empleando un...

Agricultural research and development plays an essential role in a nation's economic development, providing for food security for an ever-increasing population. In developed countries, the gap between potential and actual yield is largely closed because of a combination of advanced technologies, ...

Cultivated cassava (Manihot esculenta) has a higher rate of photosynthesis than is usual for C3 plants and photosynthesis is not light saturated. For these reasons it has been suggested that cultivated cassava could be derived from wild species possessing C4 photosynthesis. The natural abundance ...


Calatayud, Paul-AndréBaron, C.H.Velásquez, H.Arroyave, José A.Lamaze, T[Wild manihot species do not possess C4 photosynthesis]Wild manihot species do not possess C4 photosynthesis

Cassava (Manihot esculenta Crantz) is a hot-climate crop that is also grown in cool areas of the highland tropics, where yields are reduced. The purpose of this study was to evaluate the effect of growth temperature on photosynthesis of two cassava cultivars from contrasting habitat and to determ...
