We analyse the adjustment of the birch reeds to the cold and drought from the conductance, K+ filtrate, SOD, POD, MDA, content of the water-soluble protein, penetration of the bioplasm film, photosynthesis and fluorescence.

3通过对欧洲优良无性系在寒冷、干旱的胁迫下电导率、钾离子的渗透率、酶促防御系统，膜质过氧化物，可溶性蛋白含量、原生膜透性和光合、荧光等生理指标的变化，对欧洲白桦优良无性系苗期的适应性进行分析。

Results showed that all leaves consisted of epidermis, chlorenchyma, aquiferous tissue and vascular bundles. The leaves had the xeromorphic characteristics, including thickened epidermal cell wall, thickened cuticle, sunken stomata and well_developed aquiferous tissue. With the exception of this, there were remarkable differences in leaf structure among the six species.

结果表明，6种芦荟叶均由表皮、光合组织、储水组织和维管束组成，都表现出明显的旱生植物肉质叶的结构特征，表皮由一层扁平的细胞组成，其外壁加厚，并覆盖着厚的角质膜，气孔器凹陷，储水组织发达。

So the variety of L21 andLainong9217 should be planted in dry land of high yield,and the variety ofLainong8834 and YD27 in dry land of middle yield,and gaining high yieldand high efficiency.2 The researches on the flag leaf and root system senescence after anthesisand yield were studied in dry land wheat of high yield,the activity of super-oxide dismatase and catalase、and the soluble protein content、Cytokinincontent in wheat flag leaf and root system after anthesisand Cytokinincontent in grain decreased slowly,and the content ofmalondiadehydeand the Abscisic Acidcontent in wheat flagleaf and root system and the Abscisic Acidcontent in grain increasedslowly,meanwhile keep higher root vigor and the root vigor decreased slow-ly,the result would be benefit to delay the senescence and gain high yield.3 The effects of soil thickness on the senescence of flag leaf and root sys-tem、nitrogen distribution and utilization and water consumption law andyield in dry land wheat had been studied in soil column and field.

通过大田条件下旱地高产小麦耗水规律及产量变化的研究表明，4个品种耗水量、产量、水分生产率、籽粒产量中来自花后光合器官输送的比例及综合效益评判结果均以鲁麦21和莱农9217为高，而莱农8834和烟D27则与此相反，因而在旱地高产麦田应以种植鲁麦21和莱农9217为主，中产麦田以莱农8834和烟D27为主，以获得高产高效。2在旱地高产大田对鲁麦21与烟D27两品种花后旗叶、根系衰老及产量变化进行了研究，认为花后旗叶与根系SOD、CAT活性、可溶性蛋白质含量、i-PAs含量及籽粒iPAs含量降低缓慢，MDA含量、ABA含量及籽粒ABA含量增加缓慢，同时保持较高的根系活力且下降缓慢，有利于延缓衰老，形成高产。3土层厚度对旱地小麦花后衰老、氮素分配利用及产量的影响进行了研究，随土层厚度加深，根系活力、根系与旗叶SOD、CAT活性及可溶性蛋白质含量增加，MDA含量减少，土层愈薄，其根系与旗叶衰老愈快。

The two Fraunhofer lines at 688nm and 760nm are obvious in the ...

第三，研究并分析了夫琅和费暗线方法计算的688nm和760nm波段的荧光特性，结果表明该方法计算的荧光是可靠的，它与光合有效辐射关系密切，复相关系数达。。。

The focus was on the changes in metabolism of cytoplasmic membrane, adaptive responses of antioxidative systems and development of heterocyst in algal cells under microgravity.

鱼腥藻细胞的光合和呼吸活性在过重力下都不同程度的得到增强，特别是呼吸作用增强显著。77k荧光发射光谱说明在过重力下鱼腥藻细胞的光系统Ⅱ活性比在正常条件下有一定程度的增高。

Some morphological and physiological parameters of Li-1 and TM-1 weremeasured in this experiment. It showed that the contents of chlorophyll in Li-1 washigher than that in TM-1, but leaves areas and photosynthetic rate of Li-1 were lowerthan that of TM-1. The results indicated that lower photosynthetic efficiency and lackof assimilates would decrease the biomass of Li-1, and exhibited other abnormalphenotype such as curled leaves and fiber hypogenesis.

通过对突变体与标准系形态指标和生理指标的测定比较发现，虽然突变体的叶绿素含量高于标准系，但叶面积和光合速率低于标准系，说明生成同化产物的效率较低，这是造成突变体植株生物量较小的直接原因。

Super hybrid rice Gangyou 527 was used to investigate the effects of three irrigation regimes(submerged irrigation, dry cultivation, the treatment W2 that damp irrigation before booting stage, shallow irrigation at booting stage, wetting-drying alternation irrigation from heading stage to mature stage) and different amounts of N application on photosynthetic rate, activities of nitrate reductase, glutamine synthetase, glutamate synthase, endopeptidase in flag leaves, bleeding intensity in basal internodes and grain yield during grain filling, and studied correlations among the photosynthesis, nitrogen metabolism enzyme activity and root vigor at this stage.

Together with the observed low stomatal conductance, both stomatal and non-stomatal factors contribute to the midday depression in BOL.

同时由于胡杨圆形叶在13∶00h时的低的气孔导度，因而气孔因素和非气孔因素决定了胡杨圆形叶的光合午休。

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。
