Were extracted by different extracting solvents in lab, the results indicated that with the increasing of Mn concentration levels, the speciation of Mn in their roots transform from H2O-extractable species to HCl-extractable species and NaCl-extractable species, showed increases of Mn of oxalate binding and pectate binding or prontein binding in cell wall of roots; Mn of H2O-extractable species were 34.55～50.26% of total Mn in stems and increased with the increasing of Mn concentration levels, which benefited upward transport of Mn; Percentage of Mn of H2O-extractable species were 38.55～44.19% and Mn of HCl-extractable species were 20.66～28.74% to total Mn in leaves, suggesting that most Mn in leaves were the speciation of H2O-solubility organic salts or manganese oxalates. 5.

不同的提取剂对水蓼根、茎、叶的提取结果表明，随着锰处理浓度增加，水蓼根中Mn由水提取态向盐酸提取态和氯化钠提取态转化，说明根细胞壁结合的草酸盐和果胶酸盐或蛋白质结合态的Mn含量随锰处理浓度的增加而增加；在茎中，水提取态锰含量占总锰的34.55-50.26%，且随锰处理的增加其水提取态锰的比例增加，这有利于锰向上运输；水蓼的叶片中，水提取态锰占总锰的38.55-44.19%，盐酸提取态锰占总锰的20.66-28.74%，说明叶片中的锰大部分以水溶性有机盐或草酸锰的形态存在。

The "Phoenix" was just one of the dramatic "pictorial" crop formations which appeared in the fields of England last summer--and to our surprise the plant samples taken from it (and several of the other equally astounding formations) showed clear evidence of exposure to a plasma discharge: stunted and poorly-developed seed-heads, massive apical node elongation, expulsion cavities and--in several cases--node bending which could not be attributed to phototropism/gravitropism.

"凤凰"只是其中一个戏剧性的作物结构"图案"，去年夏天出现在英格兰的田地-和令我们吃一惊的是取自它的植物样本（及几个其它同样惊人的结构）显示清楚的证据，曾在一等离子体放电下暴露：发育迟缓和弱发展的种子头，大量的顶上茎节延伸，驱逐凹处及-在一些情况下-茎节弯曲并不能归因於向光性/重力影响。

And the leaf transportation percentage of 14C photoassimilates was 14.6% increased.The 14C-soluble sugar distribution percentage of CCC treatment in leaf and stem were less than those of the control,respectively,but the 14C-soluble sugar distribution percentage of CCC treatment in tuber and root were more than those of the control,respectively.The 14C-starch distribution percentage of CCC treatment in leaf,stem and root were less than those of the control,respectively.but the 14C-starch distribution percentage of CCC treatment in tuber was more than that of the control.The radioautography also indicated that photosynthate transport from top tissues to tubers was faster in CCC treatment than that in control.These results showed that appropriate concentrations at 1.5 g L-1 of CCC significantly improved the photosynthetic characteristics,transport and distribution capability of photoassimilates in potato,and as a result tuber yield would be increased.The pattern of translocation shown is held to reflect the activities of the various metabolic sources and sinks,the activities of these sources and sinks being hormonally controlled.

There are three copies of R fragment in the S mt-genome, and each copy contains two closely adjacent open reading frames: orf355 and orf77. Among these three copies two BamHI fragments were cloned, and the sequence analysis showed that cox1 and cox2 gene lies upstream of the R region in each fragment, respectively. However, they locate in different strands and head to head with R. In this study, we found that:(1) The expression of cox1 and cox2 is not affected by the transcription of R region;(2) The two copies of R region transcribe in large amount in the microspores, and produce transcripts of 1.6kb and 2.8kb, respectively, in the sterile microspores; However, the abundance of these two transcripts is reduced in the fertility restored microspores, realized through the mRNA decay, and this reduction occurs at the uninucleate microspore stage;(3) In the sterile microspores, the 5 terminus of the 1.6kb transcript contains a palindrome region that can fold into a stem-loop.

本研究发现：(1) cox1和cox2的转录没有受到R区转录的影响；(2)两个拷贝的R区在在不育花粉中高丰度表达，其转录本大小分别为1.6kb和2.8kb；而在育性恢复的花粉中，这两个转录本的丰度被大大降低，进一步分析表明这一结果是通过mRNA分子的降解途径来实现的，此降解过程发生在单核花粉期；(3)在不育花粉中，1.6kb转录本的5′末端具有一段可形成茎环结构的迴文对称序列，而在可育花粉中，其5′末端短缺了9个碱基；(4)在不育花粉和育性恢复的花粉中，R区转录本的加尾位点都集中位于一个3′茎环结构之后；(5)不管是在不育花粉还是育性恢复的花粉中，orf77区域内均在第52位和100位核苷酸处发生了不同频率的C向U的编辑，从而形成UGA终止密码；(6)不管是orf55-orf77的成熟转录本还是转录前体分子，都已被加上了Poly尾巴，表明已进入降解途径；在以上实验结果的基础上，本研究对S型CMS花粉育性的恢复机理进行了如下推测：在不育花粉和育性恢复的花粉中，orf77区域内均发生了终止编辑，即由RNA编辑产生了提前终止密码子。

Analysis indicated that the ratios of the Cd forms extracted by ethanol and by deionized water in root, and the ratios of soluble Cd in root cell showed accordancy with the ratio of Cd transported from root to aboveground parts, and also the ratios of the Cd forms extracted by ethanol and by deionized water in stem, and the ratios of soluble Cd in stem cell showed accordancy with the ratio of Cd translocated from rice straw to grain.

分析表明，两供试品种根组织中乙醇提取态和去离子水提取态Cd的比例及根细胞中可溶性Cd的比例与根系吸收的Cd向地上部的分配比例存在一致性；茎组织中乙醇提取态和去离子水提取态Cd的比例及茎细胞中可溶性Cd的比例与植株地上部积累的Cd向籽粒分配的比例间存在一致性。

Paraffin sectioning was employed to study the developmental structure of stems and leaves of Messerschinidia sibirica, especially the position, the structure and the formation and development of the salty gland. The result indicated: that salty gland of M. sibirica is from epidermic cell of stem and leaf. Based on the observation we found one primary kind of salty glands structure which consists of many cells on the epidermis including the collecting cell and the secretory cell and so on.

利用石蜡切片法研究了砂引草茎叶的解剖结构，尤其是对泌盐腺的位置、泌盐腺的形态结构及泌盐腺的发生发育过程进行了系统的研究，结果表明：砂引草的盐腺由茎叶的表皮细胞发育而成，通过观察发现在砂引草的表皮上存在着一种主要的盐腺结构，它是由多个细胞组成，包括收集细胞和分泌细胞等。

Mozzie buster of the leaves is very large, is a tender green, which grow on long, thin stems, which is about 30 centimeters, about 2 mm thick, leaves a very small, very beautiful, close to the smell is very fragrant, hand - feels very smooth, like a baby's little hands, very cute, you just look at the last touch of your hand will be like perfume, like incense, and it also provides a long green hair, like a dense, long hair quickly, often pressure have thin stems Wanle Yao, every time when my mother to call it cut their hair, Mozzie buster it can not according to the sun, and if the sun shining or not watering, it's life would soon end.

驱蚊草的叶子非常多，是嫩绿色的，它长在长长的、细细的茎上，它长约30厘米，粗约2毫米，叶子很小，非常漂亮，靠近闻起来很香，用手摸起来很光滑，就像婴儿的小手，非常可爱，你只要在上摸一下你的手就会像香水一样香了，它长的又特像密密麻麻的绿色头发，头发长的很快，经常压得细细的茎弯了腰，每当这时妈妈就给它修剪头发，驱蚊草它不可以照阳光，要是照着阳光或没有浇水，它的生命很快就会结束。

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

The response may change the fate of the turions in the second year,and affect the maintenance of the populations.

在野外池塘中，利用3种不同营养状况的底质研究底质营养盐对菹草生长及养分分配的影响，结果表明：沉水植物菹草面对底质营养盐的胁迫出现了急性的生理生化反应，在生长初期叶片总的可溶性糖含量在肥沃的底质上高于贫营养底质上；根、茎、叶和石芽各构件都具有异速生长现象，并且表现规律不一样；菹草的根冠比随底质营养盐的不同而变化；随着营养条件对菹草生长胁迫加重，根、冠的异速生长愈明显，同时石芽的N∶P和C∶N比率显著受底质营养盐的影响，而菹草叶片和茎N∶P和C∶N比率不受底质肥力的影响，这些响应将改变石芽第2年的命运和影响种群的维持；在胁迫生境下，菹草首先分配资源到无性繁殖体--石芽上以便维持种群的延续，以回避策略应对底质营养盐胁迫。
