Data were collected for cucumber genotype (CCMC) 10, 20, 30, and 40 days (i.e., vegetative, flowering, and fruiting stage) after treatment with NaCl. Values presented for comparison are means of three replications in each treatment (±SE, standard error). Means followed by the same letters are not significantly different (p ≤ 0.05) according to the least significant difference (LSD) having three replications.
