| 为了筛选耐盐樱桃砧木，用于天津市周边轻度盐碱地区栽培，本试验通过徒手切片的方法，研究了两种樱桃砧木在盐胁迫下的叶片解剖结构变化。结果表明：在盐胁迫下，四川樱桃的叶片增厚了3.99%，大青叶的减少了2.68%；大青叶的表皮层细胞增厚了23.6%，四川樱桃的减少了3.84%；大青叶的角质层增厚3.57%，四川樱桃的减少了18.31%；四川樱桃的栅栏组织层变化不大，大青叶的减少了16.42%；四川樱桃的海绵组织层增厚了31.96%，大青叶的增厚了21.27%；四川樱桃的栅栏组织和海绵组织层厚度的比值变小、减少了29.17%，大青叶的减少了20.80%。盐胁迫使大青叶叶片表皮细胞层变厚，角质层加厚，栅栏组织层变薄，海绵组织层加厚，整个叶片变薄。盐胁迫使四川樱桃表皮细胞层变薄，角质层变薄，海绵组织层加厚，整个叶片变厚。从盐胁迫下的2种樱桃叶片结构的变化综合分析认为大青叶的耐盐性明显高于四川樱桃。 |

| In order to screen salt-tolerant rootstock of cherry for sweet cherry cultivation of saline area in Tianjin, the anatomical structure of leaves in two cherry rootstock was researched under salt stress. The results showed that leaves of Cerasus szechuanica thick 3.99%, the leaves of Folium Isatidis thinned 2.68%; epidermal cells thicked, 23.6% in Folium Isatid and 3.84% in Cerasus szechuanica; the stratum corneum thicked 3.57% in Folium Isatidis , reduced 18.31% in Cerasus szechuanica; Palisade tissue did not change in leaves of Cerasus szechuanica, reduced 16.42% in Folium Isatidis; the thickness of sponge tissue was increased upto 31.96% in Cerasus szechuanica, upto 21.27% in Folium Isatidis; ratio of palisade tissue and spongy tissue was decreased for 29.17% in Cerasus szechuanica and 20.80% in Folium Isatidis under salt stress. Furthermore, the layer of epidermal, palisade tissue, stratum corneum was thicken, but sponge tissue and leaves was thinned in leaves of Folium Isatidis and under salt stress. The layer of epidermal, stratum corneum was thinned, but the sponge tissue was thicken in leaves of Cerasus szechuanica and under salt stress. Finally, the salt tolerance of Folium Isatidis was higher than that of Sichuan based on the leaf structure analysis of 2 cherries under salt stress. |
