以野生型，转反义番茄叶绿体ω-3脂肪酸去饱和酶(LeFAD7)基因株系T2-8和转正义LeFAD7基因株系T2-7为试材，测定了类囊体膜脂脂肪酸组成，盐胁迫后的光合参数，叶绿素荧光参数和叶绿体活性氧清除酶活性。

Results showed that the peanut seeds soaked with the suitable rare earth concentration, not only increased chlorophyll content and photosynthetic intensity, but also chlorophyll in leaf cell enhanced. The chloroplastid texture intact, and the amounts of basal granule lamella increased with tight arrangement, and improved the absorption and transformation of light and energy.

结果表明，适宜浓度稀土浸种花生不仅提高了叶绿素含量和光合强度，而且还促进了叶细胞叶绿体的生长发育，使叶绿体结构完整、排列整齐，基粒片层数增多，紧密度高，从而有利于光能的吸收和转化，提高荚果产量。

Seedlings of these mutants subjected to chilling stress became chlorotic and had half the chlorophyll content of wild-type.

这些突变种的幼苗株在遭受低温胁迫时，比起野生型，叶绿素含量少了一半。

Correlation analysis of both chlorotic plants and plants staying green of the F3populations revealed that there was a significant positive correlation between yield index values and the phy...

相关性分析表明收获指标与生理指标，如净光合速率、气孔导度、叶绿素含量等呈显著正相关；而与细胞间CO2 浓度及丙二醛含量呈显著负相关。

The obtained results show:After applying Yelükang ball fertilizer,the active iron in the chlorotic fruit tree leaves increased by 8.7%~20.2%,the chlorophyll content of apple tree increased by 18%;the chlorotic degree of fruit trees decreased 2~3 scales,the yield per tree increased by 56%~89%.

研究结果表明：施用叶绿康球肥可使失绿果树叶片的活性铁提高8.7%～20.2%，苹果叶片的叶绿素含量提高18%；果树失绿程度降低2～3级，果实单产提高56%～89%。

The feature Chromophoric dissolved organic matter and its source in Meiliang bay and Da Taihu lake in Taihu Lake are analysed based on every 2 time′s samplings in summer with algal bloom and winter.

基于2004年夏季水华暴发期和冬季在梅梁湾及大太湖各2次采样，分析了夏季、冬季CDOM的特征及其可能的来源，发现夏季CDOM吸收系数、叶绿素a浓度均明显高于冬季，DOC浓度、CDOM吸收系数a(355)的变化范围分别为5.17～12.42 mg/L、2.57～6.77 m-1，最大值均出现在冬季(12月15日)的直湖港入湖口。

Ciliata var. pubescens had the higher utilization efficiency on weak light. The results suggested that the control of soil water content and irradiance might help to promote the growth of T. ciliata var. pubescens.

在遮荫条件下，毛红椿苗木通过增大叶面积、提高叶绿素含量有效地利用较弱的光辐射，形成适应遮荫条件的生态生存对策。

Study on the changes of chlorophyll fluorescence parameters in Cinnamomum japonicum var.

［目的］探讨NaCl胁迫对普陀樟叶绿素荧光参数的影响。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
