- Therefore research on siderophores is very significant to interpretation of high nitrate low chlorophyll(HNLC... 高接种量东海原甲藻能分泌较多的铁载体,并在较短时间到达峰值。
- Contents of chlorophyll a and chlorophyll b decreased, while content of carotenoid, ethylene release and weight loss increased during storage. 贮藏过程中花蕾的C值和 H值增加,叶绿素a与叶绿素b含量下降,类胡萝卜素含量增加,花蕾的失重率和乙烯释放量增加,维生素C含量迅速减少。
- The content of chlorophyll (chlorophyll a and chlorophyll b), photosynthesis rate, transpiration rate, intercellular CO2 concentrations, and stomatal conductance was all reduced under water stress at different development stages. 不同生育时期水分胁迫下使叶绿素含量、光合速率、蒸腾速率、细胞间隙CO2浓度、气孔导度都有不同程度降低。
- The content of starch, soluble sugar, amino acid, chlorophyll a, chlorophyll b and carotenoid of leaves of both APRI and FPRI are less than CI, but the content of proline and carotenoid and the activity of SOD and POD are higher than CI. APRI和FPRI处理后期的油桃叶片,淀粉、可溶性糖、氨基酸总量、叶绿素a、叶绿素b的含量都低于CI,而Pro和类胡萝卜素含量以及SOD、POD的活性高于CI。
- The contents of chlorophyll a,chlorophyll b and chlorophyll(a+b) in leaves of C. cajan had a peak in August and then declined while for M.fortunei,besides a peak in August,there was another peak in October. 木豆的叶绿素a/b的季节变化呈递减趋势,相反,十大功劳呈上升趋势。
- Chlorophyll A content significantly decreased along with waterlogging time, whereas chlorophyll B and carotenoid contents presented indistinctive changes after different waterlogged durations. 在不同处理阶段这些指标下降的幅度不同: 初期的下降幅度最大, 后期下降幅度减少, 其中根系活力在后期还有所回升。
- Therefore,there are reasons assume that higher chlorophyll(a+b)contet and lower chlorophyll a/b ratio can be ued as a crterion ofselection for high net photosynthetic rate varieties in the areas where thesolar radiation level is low. 根据以上结果,本文提出,在辐射能量低的地区,选育叶绿素(a+b)含量较高、叶绿素 a/b 比值较低的品种是具有一定实践意义的。
