- Example Sentences:
| 1. | Experimental results indicated that supplemental uv - b radiation decreased the number of leafy thallus and retarded the growth of leafy thallus
结果表明，在uv - b辐射条件下，紫萍生长缓慢，叶状体数目比对照明显减少。 | | 2. | Effects of uv - b radiation on the morphological structure and physiological biochemistry in leafy thallus of spirodela polyrhiza were investigated in the present study
本文研究了紫萍在形态结构和生理生化方面对uv - b辐射的响应。 | | 3. | The present results indicated that enhanced uv - b radiation affected the absorption of nitrate , assimilation of nitrogen and synthesis of amino acids
这些都严重影响了紫萍对硝酸盐的吸收、氮素的同化和氨基酸的合成，进而也影响了植物体内蛋白质的合成。 | | 4. | Duckweeds ( spirodela polyhiza ) were used as my experiment material in the present thesis to study physiological and biochemistryresponses to suoolementary uv - b radition
本文以紫萍( spirodelapolyhiza )为材料，研究了紫萍在生理生化机制方面的响应，以期为同类研究提供参考。 | | 5. | Enhanced uv - b radiation greatly decreased the content of photosynthetic pigments : chlorophyll a , chlorophyll b , and total chlorophyll . supplemental uv - b radiation induced the antioxidant system change
Uv - b明显降低紫萍光合作用色素(叶绿素a 、叶绿素b及总叶绿素)含量，这将导致光合作用下降。 | | 6. | ( 3 ) uv - b radiation increased the phenylalanina ammonia - lyase ( pal ) activity in leafy thallus of duckweeds , and as a consequence , flavonoids were accumulated . flavonoids synthesis induced by supplementary uv - b is an adaptive response of duckweeks under enhanced uv - b radition
( 3 )紫萍可以通过提高uv - b吸收物质如类黄酮合成酶苯丙氨酸氨裂解酶( pal )活性，促进类黄酮的积累来适应uv - b辐射的胁迫。 | | 7. | With the increase of exposure time , the antioxidative ability of spirodela polyhiza dereased , sod and ap activities were induced , and asa content of treated plants were always lower than those of control plants , but the proline ( pro ) contents in treated plants increased . these factors would break the balance of the metabolism of ros and the active oxygen accumulation in leafy thallus of spirodela polyhiza could be the result , the membrane lipid peroxidation was accelerated ( mda content increased ) , ultra - microstructure of chloroplast was damaged , photosynthetic capacity dereased , biomass ( dry weight ) reduced
实验研究结果如下： ( 1 ) uv - b辐射处理后前2天，紫萍超氧化物歧化酶( sod )和抗坏血酸过氧化物酶( ap )等抗氧化酶系统有不同程度的升高，随着uv - b处理时间的延长，紫萍体内抗氧化保护系统能力下降， sod和ap的活性下降，并且非酶类抗氧化物质抗坏血酸( asa )含量一直低于对照组，而脯氨酸( pro )的含量则一直在升高。 | | 8. | Activity of phenylalanine ammonia - lyase ( pal ) was increased by uv - b radiation , and as a consequence , uv - absorbing compounds were accumulated . it was inferred from our results that the accumulation of uv - absorbing compounds such as flavonoids may be a common response for plants in resistant to enhanced uv - b radiation
在uv - b处理下，紫萍的苯丙氨酸氨基裂解酶( pal )活性上升，并导致其体内吸收uv - b的物质积累，推测类黄酮积累可能是植物抵御uv - b逆境的一个共同效应。 |
