| The cold stress during the early stages of rice development can cause uneven and decrease in germination rate. The aim of this study was to evaluate different rice cultivars related to the chlorophyll content and biomass accumulation, the latter measured after a period of recovery, in response to this stress, looking further establish which variable best serves the discrimination of genotypes for the trait in question. To this end, the follow cultivars were used: Ambar, Diamante and Oro, considered tolerant; BRS Fronteira and BRS Pampa, moderately tolerant; IRGA 417, BRS Pelota, BRS Taim and BRS Sinuelo CL, seen as sensitive to cold. The sowing was carried out in vessels of 0.2 L with vermiculite substrate in a completely randomized design with three... |
