Metales
 Los elementos
 metálicos, pueden
 influir directamente
 en los procesos de
 crecimiento,
 senescencia y la
 generación de
 energía en las
 plantas.

Pregunta General
   ¿El contenido de metales en la planta
    de maíz (jugo de tallo), que tan
    influenciado esta por factores abióticos
    o el genotipo?
   1.- ¿Diferentes genotipos      tienen distinta
    concentración de metales (Ca, Na, Mg, K, Li, Fe,
    Cu, Zn, Mn, Pb, As, Hg, Cd)?


   2.- ¿En diferentes localidades (suelos con
    alto/bajo contenido de nitrógeno), hay
    diferencia en la concentración de metales en
    los jugos de tallo de maíz?

   3.- ¿la presencia de los metales en el suelo afecta
    la composición del jugo de tallo y calidad
    nutricional del forraje (azucares, aminoácidos,
    ácidos grasos, etc.)?
