AB  - Taking three Hemerocallis cultivars (&#039;Jingzhouhua&#039;, &#039;Qingchong&#039;, &#039;Changzuizihua&#039;) with different salt tolerance as materials, the effects of 0-200 mmol/L NaCl on root morphology and Root Border Cell (RBC) characteristics were investigated using hydroponic and root suspension culture methods and one-way analysis of variance (ANOVA). The results showed that the root morphology indicators and activity of the high-salt-tolerant &#039;Jingzhouhua&#039; decreased less than those of the medium-salt-tolerant &#039;Qingchong&#039; and salt-sensitive &#039;Changzuizihua&#039;. As the salt concentration increased, the number and viability of RBCs in these three cultivars decreased in the order of &#039;Jingzhouhua&#039; &lt; &#039;Qingchong&#039; &lt; &#039;Changzuizihua&#039;. NaCl stress increased the apoptotic rate of RBCs and the thickness of the mucilage layer; &#039;Jingzhouhua&#039; had the lowest apoptosis rate and the thickest mucilage layer, followed by &#039;Qingchong&#039; and &#039;Changzuizihua&#039;. Under NaCl stress, maintaining a high number of RBCs, survival rate, and mucus layer thickness helps stabilize the root function and morphology of &#039;Jingzhouhua&#039;, which is the reason for its strong salt tolerance.
