the structures of upper leaf mesophyll cells of hg103 and lg122 are not very different when applying k, but lower leaf palisade tissues of lg122 are more neatly arranged than those of hg103.
缺钾时,hg103上部叶叶肉的上表皮细胞比lg122排列的较为整齐,栅栏组织和海绵组织形状较规则;
the results indicated that the leaf thickness decreased obviously with the decline of irrigation amount while the number of palisade tissues of the unit length increased gradually.
