| 1. | The smallest veins are in direct contact with chlorenchyma, both palisade and spongy tissue . 最小的脉是直接和栅栏组织及海绵组织的绿色组织相联结。 |
| 2. | 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。 |
| 3. | The spongy tissue take a larger scale in mesophyll than palisade parenchyma , and contain abundant chloroplasts 海绵组织多于栅栏组织,并含有丰富的叶绿体。 |
| 4. | There exists a layer of big crystal cells in the spongy tissue of lespedeza dahurica ( laxm . ) schindl 兴安胡枝子叶的海绵组织内,在临近栅栏组织一侧分布着一层大型含晶细胞。 |
| 5. | Most of callow stirpes are developed into assimilative branches . there is a thick layer of palisade tissue under the epidermis 幼茎多发育为同化枝,表皮下有一层较厚的栅栏组织。 |
| 6. | In the main vein there exist some abnormal vascular bundles . salt glands were observed on epidermis . the cutin layer is thin 叶脉为异形维管束;叶上表皮有盐腺;角质层薄;栅栏组织中有巨型簇晶存在于胞间空腔中。 |
| 7. | 2 the salt - resistant characteristic which is adapt to depressed level of photosynthesis , such as the formation of double palisade tissue , and soon 适应光合水平降低的抗盐结构特征。如茎皮层同化组织的形成;叶片双侧栅栏组织或外周栅栏组织的形成等。 |
| 8. | 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。 |
| 9. | There exist a lot of mucus cells in palisade parenchyma and vein - parallel mesophyll cells . the cells of cortex are loosely arranged , just like aerenchyma . there are many protein - bearing cells in pith 角蒿叶为等面叶,角质层薄,栅栏组织及平脉叶肉细胞中有大量粘液细胞;茎中皮层排列疏松,形成通气组织,髓中有大量的蛋白细胞,环髓带明显。 |
| 10. | Drought resistances of leaves of 13 rasberry and blackberry were measured based on 7 xeromorphic indexes , including thickness of leaves , ratio of palisade tissue thickness to cutis tissue , thickness extent of palisade cell density , thickness of cuticular , thickness of two sides of cutis 摘要选取7项叶片旱生结构指标(叶片厚度,栅栏组织厚度叶肉组织厚度,细胞密集度,角质层厚度,上、下表皮厚度) ,观察测定了13个树莓和黑莓品种的叶片的相关指标。 |
