Resumen

ARGENTEL, L et al. Efecto de la salinidad sobre la fenología, los componentes del rendimiento y su relación con la tolerancia varietal a la salinidad en trigo (Triticum aestivum y T. durum). cultrop [online]. 2008, vol.29, n.3, pp. 53-57. ISSN 0258-5936.

Salinity effect on the phenology, yield and its components was studied in wheat varieties established in the eastern part of the country, which had been obtained or selected in Cuba. Twelve varieties were established in ponds from the experimental area of “J. Dimitrov” Agricultural Research Institute using two experimental variants: a saline treatment with irrigation at an electric conductivity (EC) of 8 dS.m-1 and a control treatment EC=0.02 dS.m-1. Results indicated that salinity susceptibility in wheat appears at flowering and such damages are more notable in T. durum. The most affected yield variable by salinity was full grain number per spike; consequently, there were mean yield effects from 13 to 68 %. These results enabled to classify varieties with different tolerance indexes to saline stress
