叶绿素

The use of the eutrophication threshold to the study of the red tide in shrimp ponds along the coast of our country as proposed in this peper will be of great value for reference.

本文提出了虾池中使用叶绿素a富营养化阈值含量对研究我国沿海虾池赤潮具有重要的参考价值。

The results showed that the mixed fertilizer increase chlorophyll concentration sand nutrition, enhance the disease resistance and prolong the green period of Poa pratensis.

不同叶面肥料和自制草坪复混肥施肥试验证明：自制草坪复混肥可增加草坪草叶片叶绿素的含量和养分含量；提高草坪对褐斑病的相对防效；延长草坪绿色期。

Root cutting at PI markedly influenced chlorophyll content of third leaf.

穗分化期切根对叶绿素含量的影响以倒3叶最显著。

The results showed that root cutting and potassium application could increase the chlorophyll content of leaves in upper and middle stalk positions, which resulted in larger leaf area and more dry matter accumulation in the leaves.

结果表明：在不同施氮量条件下，打顶时断根追钾促进了烟株中、上部烟叶叶面积的扩展和叶质重的增加，其叶绿素含量尽管高于对照，但没有影响到烟叶的落黄和成熟。

More than sixteen chemotaxonomic chlorophylls and carotenoids could be identified and quantified within 30 minutes in a single run.

可在30分钟内分离并鉴定至少16种在化学分类上较为重要的叶绿素和类胡萝卜素。

With 4-year-old Vitis vinifera var. Red Globe as the tested material, 4 kinds of shaping modes were set up as FI type, L type, V type and fan type and the mean leaf area, chlorophyll content, photosynthesis rate, Rubisco activity in the leaves on the middle part of grape trees with different shaping modes and their fruit quality were determined and compared.

方法］以4年生红提葡萄为试材，其整形方式设FI型、L型、V型和扇型4种，对不同整型葡萄中部叶片的平均叶面积、叶绿素含量、光合速率、Rubisco活性和果实品质进行测定与比较。

The experiment analyzed the vertical distribution pattern of canopy leaf nitrogen and leaf chlorophyll relative value, differences in different layer-leaves for different nitrogen levels in summermaize Zeamays L.

拔节期、灌浆期和成熟期3个生育期冠层叶片氮素、叶绿素相对值的垂直分布规律及其差异；同时对各层叶片含氮量、SPAD值与施氮量进行相关分析。

The rusults indicated that the temperature in forest was lower and the growth of ginseng was slower than out of forest, the yields were also lower; with the increase of ginseng age, the rate of net photosynthesis became higher; when the canopy density of forest reached to about 0.7～0.8, the net photosynthesis, hight, root weight, transpiration,chlorophyll conten of ginseng were higher than others, indicating that both lower and higher canopy density would reduce the rate of net photosynthesis of ginseng, and that the canpoy density of stand could be adjusted to satisfy the temperature and lighting for ginseng, and to provide the optimum ecology enviorment for the growth of ginseng.

结果表明，在生长季节内，林内温度低于林外温度，林下人参生长发育较差，产量较低；林分郁闭度为0.7~0.8时，人参的净光合速率、株高、单根重、叶绿素含量等指标较高；而郁闭度过高或过低都会影响人参生长发育；随着人参年龄的增加，净光合速率有逐渐升高的趋势。通过人为调节林分郁闭度的方式来满足人参对温度和光照因子的需求，为林下人参生长发育提供最适宜的生态环境。

However,the decline of stomatal conductance in longan leaves treated with acidrain of pH2.5 was paralleled with the decrease of apparent quantumyield,and these showed the reduction of Pn was resulted from thecombination of stomatal factors and non-stomatal factors.

酸雨胁迫使细胞质pH值的降低，改变了叶绿体周围介质的H+浓度，减少了形成ATP的动力ΔuH+，导致光合磷酸化活性和H+-ATPase活性下降、电子传递链的破坏和磷酸化解联，从而使叶绿素不能对光能有效吸收、传递、转换。

The effect of N forms and Ratios on iron nutrition in hydroponically grown lettuce were investigated. It was found that suitable ratioNO3--N:NH4+-N:CO(NH22 =6:6:0 in nutrient solution can significantly promote plant growth, raise chlorophyll content, improve plant iron utilization efficiency, and reduces nitrate content accumulation in leaves, and the cost of nutrient solution was thus reduced.

硝态氮、氨态氮与酰胺态氮及其不同配比对水培油菜铁素营养的影响试验，结果表明，不同形态氮素显著影响植物的铁素营养状况，NO_3~--N：NH_4~--N：CO(NH_2)_2为6：6：0的处理比单一NO_3~--N使用处理，能促进水培油菜生长，提高叶绿素含量，增加植物体内铁的活性，降低叶片中硝酸盐含量的积累，降低营养液成本。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
