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...

De acuerdo con las demográficas actuales, se prevé que la población en América tropical se duplicara en los próximos 25 años; como consecuencia, habrá mayor demanda de carne y leche, la cual podrá satisfacerse solo aumentando la producción agropecuaria. Estos factores aumentaran la presión sobre ...
