From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.
本实验分两部分:第一部分、对转化番茄的形态及细胞显微结构进行观察与分析,实验表明转化番茄形态与对照相比有明显的变化,其叶面积变小,叶形收拢,这种结构可有效地减少水分的蒸发,缓解由盐胁产生的生理干旱;组织解剖结构结果显示,耐盐番茄在细胞结构上发生了明显的变异:其气孔器倾向下陷,表皮毛增多,叶脉微管组织不发达,微管束周围出现增多的贮水细胞,叶缘及其它部位表面分化出大型的多细胞分泌型结构,这些结构与转化番茄后代较强的耐盐能力有关。

This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.
