CONTENIDO DE CLOROFILA E IONES EN LA VARIEDAD DE TRIGO HARINERO CUBA-C-204 EN CONDICIONES DE ESTRÉS SALINO

Chlorophyll (a) content and ion accumulation were determined at different plant organs of a Cuban bread wheat variety, Cuba-C-204, by applying different salinity stress levels by NaCl adjusted to electric conductivities (CE) of 4, 8 and 12 dS.m -1 , and a control treatment with distilled water and CE of 0.02 dS.m -1 . Dry matter accumulation per organ and root/shoot relationship was also calculated. Such determinations were performed at seedling and flowering stages following the validated methodologies. A chlorophyll content reduction was recorded as salt concentrations increased, which were just significant between the control and 12 dS.m -1 . There was a significant negative correlation between chlorophyll content and Na in leaves during both stages studied, whereas the other microelements did not show this behavior. A root dry weight reduction was recorded as salt concentration increased. When evaluating leaf cation content, there was a negative correlation between K
