Relative water content RWC (%) of the leaves of BR16 and Embrapa 48 genotypes under different water potential. Bars represent ± standard error (n = 5, where n represents the number of plants, t test p < 0.5). Different lower case letters indicate significant differences between averages of the same treatment in different cultivars, and capital letters show significant differences between averages within the same cultivar under different treatments. IR irrigated, NI non-irrigated treatments
