Comparison of the total mass of the non-saline and coastal ecotypes of Ipomoea cairica under non-saline and saline treatments.

Saline treatment: 4 g L-1 NaCl solution; Non-saline treatment: pipe water. Different symbols indicate significant differences (α = 0.05). Values presented are means ± SE.

盐处理组：4 g·L⁻¹氯化钠（NaCl）溶液；非盐处理组：自来水。不同符号表示组间存在显著性差异（α=0.05）。所呈现的数值为平均值±标准误（standard error, SE）。
