Data were collected for cucumber genotypes (Jinyou 1# and Chanchun mici (CCMC)) 40 days (i.e., 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. HBL, 28-homobrassinolide; AMF, arbuscular mycorrhizal fungi; CK, control.
