The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.

利用光学显微镜和扫描电子显微镜观察了6种杜鹃属植物的叶片结构，结果表明，它们具有共同形态结构特征：典型的异面叶，上表皮由2~3层细胞组成，内大外小或内、外等大，有较厚的角质膜，无气孔器分布；下表皮均由1层细胞组成，排列紧密；栅栏组织由2层以上长柱形细胞组成，排列紧密；海绵组织细胞较短，排列较疏松，细胞间隙较大；均有表皮附属物。

The results showed that leaf epidermal cells were polygonous or irregular in shape. Stomatal complexes only present on abaxial epidermis and the stomata was paracytic type. There were five types of anticlinal walls of abaxial and adaxial cells (straight, rounded, undulated, sinuous, straight-curved). Trichomes on abaxial epidermis exist or not. Ornamention types of periclinal walls could be divided into punctuate, smooth and striate. Ornamention of periclinal walls on inner side of abaxial epidermal cells varied widely (irregular, smooth, roughly reticular, micro hairy, granular, scaly).

结果表明：润楠属植物叶表皮细胞形状为多边形或不规则形，气孔复合体均为平列型且仅分布在下表皮；上下表皮细胞的垂周壁式样有5种类型：平直、圆滑、技波、波状、平直－弓形；下表皮毛被有或无；上表皮平周壁纹饰类型有：点状、平滑、条纹；下表皮内面平周壁纹饰类型有：不规则、平滑、粗糙网状、微毛状、颗粒状、鳞片状。

Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied. The patterns of anticlinal walls are straight, arched or sinuous, and the raphal cuticular striastriae are occasionally observed on periclinal walls. Stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all Species. The slomata apparatus mainly belong to the paracytic type and latercylic type; rarely anomocytic type occurs along with the paracytic one.

结果表明：这些植物叶片的上、下表皮细胞呈多边形或不规则形，垂周壁式样为平直、弓形或波浪状，平周壁偶有脊状条纹；少数种类上表皮还有气孔器或分泌细胞，所有种类下表皮具气孔器和分泌细胞；气孔器类型以平列型和侧列型居多，偶尔有无规则型；气孔极区呈稍角质加厚或棒状加厚，稀T形加厚。

结果：6种麻黄属植物之间气孔密度、茎、叶表面特征存在不同程度的差异；气孔表现出典型旱生植物的特征，略下陷，气孔保卫细胞被厚的角质层覆盖，并形成突起状角质唇状物；气孔大小、形状在种之间无明显区别；叶表面、茎表面气孔均属于无规则型，但形状明显不同，前者主要呈长方形或六边形，后者为窄条形或哑铃形。

Variety widely cultivated in south China,were studied by foliar 1.5 g L-1 CCC application after pot planting virus-free plantlets at the stage of budding.It was found that at the stage of tuber bulking,spraying CCC plays a prominent regulating role in the photosynthesis of Zhongshu 3.The net photosynthetic rate,stomatic conductance,intercellular CO2 concentration and transpiration rate of leaves were superior to those of the control.CCC markedly increased the contents of chlorophyll and carotenoid.CCC significantly increased the leaf photosynthetic productivity and improved economic yield.

品种广泛种植，在中国南方，研究了叶面肥1.5克升- 1 CCC认证申请后，盆栽种植无病毒的植株在阶段budding.it被发现，在阶段的块茎膨胀，喷涂中华基督教会扮演一个突出的调节作用，在光合作用的中枢三，净光合速率（ 1 ），气孔导度的，胞间CO2浓度和蒸腾速率的叶片均优于那些该control.ccc显着增加的内容，叶绿素和carotenoid.ccc显着增加叶片光合生产力，以及改善经济产量。

Cd inhibited the absorption of Mg and Mn in roots. However, Cd could stimulate the absorption of Fe in roots. Moreover, Cd inhibited the absorption and utilization Mg, Mn and Fe in leaves. 4. Cd inhibited the photosynthesis of Populus clones. Cd showed no significant inhibition to net photosynthesis rate, stomal conductivity and transpiration rate versus the control, under 10μM Cd treatment.

Cd胁迫还对杨树光合作用产生影响，低浓度Cd对杨树光合速率无影响，中高浓度Cd对杨树净光合速率、气孔导度和蒸腾速率等具有抑制作用，而且随着处理时间的延长和Cd胁迫浓度的提高而逐渐加大。

Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.

研究表明，冷、暖型小麦叶表皮气孔器的长度和宽度、气孔密度、穗下节间中维管束面积均无显著差异；冷型小麦倒二节间中维管束面积明显小于暖型小麦；冷、暖型小麦穗下节间、倒二节间单位横截面积中维管束数目、维管束总面积占茎横截面积的百分率均有显著差异。
