And there exists salt gland which is similar with the salt gland of sophora flavescens ait on the under epidermis 在叶的下表皮上发现了盐腺。该盐腺结构类似苦参盐腺结构。
On the under epidermis and petiole epidermis of sophora flavescens ait . is founded salt gland which has a secretory cell and a basal cell for the first time 首次在苦参叶的下表皮及叶柄的表皮上发现了盐腺。该盐腺由一个头细胞和一个基细胞构成。
Large cavities also exist under epidermis and occasionally crystals can be found in some of these cavities . there exist many projecting constructions shaped like two guard cells on under epidermis 叶表面无表皮毛,表皮下有大的空腔,内有晶体;下表皮具有大型类似保卫细胞的双细胞突起。
The results show that the characters such as shape and pattern of anticlinal walls of epiderm , stomatal density , stomatal distribution and epidermal hairs possess the classific value of species 下表皮的结构远较上表皮摘要复杂,表皮细胞形态各异,有为数较多的气孔器,气孔密度、分布式样各不相同。
Most of these species had simple hairs . the stomatal apparatus is paracytic type with one or two subsidiary on both or either side of the guard cells . three types of anticlinal walls of epidermal cells are recognized : straight , sinuolate or sinuate 表皮细胞垂周壁式样、气孔分布密度及式样、下表皮毛被的有无、多少及毛的长度、下表皮角质突起饰物的形态等具有一定的分类学意义。
With colourless nail polish , study on the stomatic distribution of outer epidermis in the young stem , aged stem and aged leaf sheath , and adaxial and abxial leaf epidermis of young and aged leaves in s . purpurea , z . pendula and c . communis was conducted 用无色指甲油印痕法对鸭跖草科的紫竹梅、吊竹梅和鸭跖草的幼茎、成熟茎、成熟叶鞘的外表皮和幼叶、成熟叶和上、下表皮的气孔分布进行观察。
With colourless nail polish , study on the stomatic distribution of outer epidermis in the young stem , aged stem and aged leaf sheath , and adaxial and abxial leaf epidermis of young and aged leaves in s . purpurea , z . pendula and c communis was conducted 摘要用无色指甲油印痕法对鸭?草科的紫竹梅、吊竹梅和鸭?草的幼茎、成熟茎、成熟叶鞘的外表皮和幼叶、成熟叶和上、下表皮的气孔分布进行观察。
Using rt - pcr and race techniques , a full - length cdna vfcpkl and a partial cdna vjcpk2 were firstly successfully cloned from broad bean epidermal peels and leaves respectively , and a preliminary study was conducted on the expression pattern of vfcpkl 本研究采用rt - pcr技术并结合race策略,成功地首次从蚕豆下表皮和叶片中克隆了编码cdpk的全长cdnarvfcpk1和cdna片段vfcpk2 ,并对vfcpk1的表达特征进行了初步研究。
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。
By northern and western blot analysis , we examined expression pattern of vfcpk1 in different parts including roots , stems , leaves , mesophylls and epidermal peels in broad bean at mrna or protein levels , and effects of different external stress treatments on vfcpkl 通过northem和westernblot分析,我们研究了蚕豆钙依赖蛋白激酶vfcpk1在蚕豆不同部位包括根、茎、叶、叶肉和下表皮中的mrna和蛋白质水平上的表达情况以及不同外界胁迫处理对vfcpk1表达的影响。
