p deficiency induced the adaptive change in the microstructure of leaves. neither pn nor p efficiency was correlated with leaf thickness, palisade tissue thickness and spongy tissue thickness.

结果表明：缺磷胁迫下大豆叶片的显微结构发生了适应性变化，叶片厚度、栅栏组织厚度和海绵组织厚度与光合速率及磷效率相关性不大；

its palisade tissue is composed of 1~2 layers of cylindrical cells.

叶肉组织发达，栅栏组织由1~2层排列整齐的圆柱形细胞构成；

the wider palisade tissue cell was, the better the growth and development of larvae was.

栅栏组织细胞宽度越大，对幼虫生长发育越有利；

the thickness and cell layers of palisade tissue were consistent with the thickness of leaf.

栅栏组织的厚度和层数与叶片的厚度趋势一致。

the thickness of palisade tissue had strikingly negative relationship with the increment of trunk girth.

栅栏组织厚度与干周生长量显着负相关；

there are 2-3 layers of long-column-shaped palisade tissue under the upper epidermis, and there are a great number of mechanical tissues which made up of vascular bundle sheath .

上表皮下方有2-3层长柱形的栅栏组织，在主脉大侧脉外方具有由大量机械组织组成的束帽或束鞘。

the palisade tissue cells were bigger and its arrangement was relaxed;

叶中栅栏组织细胞大，排列舒展；

soil moisture and potassium amount could improve potassium content of palisade tissue and spongy tissue.

土壤水分和钾用量能提高叶片栅栏组织和海绵组织的含钾量。

palisade tissue is rich in saliferous vacuoles, while vascular bundle sheath is obvious.

栅栏组织富含含盐液泡泡，维管束鞘明显。
