| Popis: | Sugar beet (Beta vulgaris L.) high yields have been achieved through irrigation and this crop is described as coping with mild salinity (40–120 mM NaCl). However, during seed germination, sugar beet is salinity sensitive and soil salinity should not exceed 3 dS/m. Wild beets, ancestors of sugar beet, are naturally able to germinate and grow in saline environments. Salinity tolerance during germination and early seedling development of three Portuguese wild beet ecotypes [Comporta (CMP), Oeiras (OEI), Vaiamonte (VMT)] and one sugar beet cultivar (Isella) was evaluated. Concerning germination, VMT outperformed all the other beets, with 98% (± 2%) of glomerules germinating in 200 mM NaCl after 14 days of scarification. However, in 500 mM NaCl, only CMP was able to initiate and maintain radicle emergence, though in a very small extension ( |
