Higher Ca distributed in bulliformcell than in mesophyll cell and bundle sheath cell of dune reed, higher Mg distributedin mesophyll cell and higher K, Na and Cl distributed in sheath cell HigherNa and Mg distributed in mesophyll than in bulliform cell and bundle sheathcell of light salt meadow reed, and higher K, Ca and Cl distributed in itsbundle sheath cell. Higher Na and Mg distributed in bulliform cell than in mesophyllcell and bundle sheath cell of heavy salt meadow reed, higher K, Ca and Cl distributedin its mesophyll cell. This paper discussed the distribution conditions of theabove five ions in leaf cell of the four reed ecotypes and the meaning ofphysiological adaptation to habitat in detail.

沙丘芦苇的泡状细胞内Ca分布较叶肉细胞和鞘细胞高，叶细胞内Mg分布较高，在鞘细胞内K，Na和Cl布较高；轻度盐化草甸芦苇叶肉细胞内分布了较多的Na和Mg，在鞘细胞内K，Ca和C1分布较叶肉细胞和泡状细胞高；而重度盐化草甸芦苇泡状细胞内分布了较多的Na和Mg，叶肉细胞分布了较多的K，Ca和Cl；详细讨论了以上五种离子在不同生态型芦苇叶片内不同细胞类型的分布状况与环境适应的意义。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

The new plant type Indica and Japonica varieties showed somewhat check heterosis whencrossed with one of the four sterile lines. America Japonica varieties showed few fillers andlower seed set ratio and Africa Japonica varieties, Nuda varieties, Javanica varieties have fewtillers and taller plant height, so they could not be used directly in Japonica hybrid ricebreeding program.

美国稻的分蘖少且结实率较低，产量优势不大；非洲稻的分蘖少，实粒数也少，株高太高，无法直接利用；新株型粳稻与培矮64s、N422s配组有一定的优势，新株型籼稻与N422s、108s配组的优势也较大，在华北两系杂交粳稻育种中也有一定的利用价值；光壳稻和爪哇稻的株高偏高，无法直接利用，可间接利用这两个生态型千粒重大的特点。

Through the research we have established in planta transformation system, mutangenesis and screening system for salt sensitive mutants, and constructed a cDNA library under salt stress and cloned a serious of salt-tolerance related genes which had been confirmed the function by overexpression in Arabidopsis or antisense expression in Thellungiella. We also compared different mapping strategy through the analysis of the genetic polymorphism between ecotypes, and establishing mapping population for physical mapping.

建立了小盐芥的转化体系与盐敏感突变体诱变与筛选体系，构建了盐胁迫下的cDNA文库并克隆了一批耐盐相关基因，并通过模式植物拟南芥转化与小盐芥的基因反义表达证实其功能，通过不同生态型小盐芥的遗传多样性分析探讨了基因组作图的策略，建立了作图群体并开始进行物理图谱构建。

In bud stage of mustards ecotype Xuelihong and Yuanyejie were transformed with in planta vacuum infiltration by an Agrobacterium tumefaciens strain GV3101 carrying hy-gromycin resistance gene. Effects of different factors on transformation frequency with in planta vacuum infiltration were studied.

以蕾期的芥菜生态型雪里蕻和圆叶芥为试材，在携带潮霉素磷酸转移酶标记基因的根癌农杆菌菌株GV3101的介导下，对影响芥菜植株原位真空渗入遗传转化效果的真空渗入时间、根癌农杆菌悬浮孢子的浓度、渗入培养基、感染方式以及根癌农杆菌菌株等进行研究。

Rosaceae Cherryis the case of a small shrub, for our unique fruit trees, is a fruit, wood, flowers, multi-purpose ecological medicine species, with high survival rate, grow fast, use a wide number of characteristics of high efficiency excellent species.

钙果是蔷薇科樱桃属的一种矮小灌木，为我国特有的果树，是集果、木、花、药多用途的生态型树种，具有成活率高、生长快、用途广、效益高等诸多特点的优异树种。

The results showed that there were significant differences among fungal species or ecotypes in all above index,which varied with soil types.First,six fungi could colonize maize root on three soils,and the fungal colonization rate was higher on soil collected in the region that had been screened for cinnamon soil and brown soil.

结果表明，6种菌株在上述指标上存在显著的种间或生态型差异，土壤与菌株间存在显著的交互作用。6种菌株在3种土壤上都能与玉米形成菌根，在褐土和棕壤上大多数菌株在分离地所在地区土壤类型上的菌根侵染率较高，说明其对该土壤条件的适应性较强；在红壤强酸性土壤条件抑制了菌根真菌的侵染。

There are many different races and ecotypes throughout its range, the more widespread being generally tetraploid with local diploid races particularly in the Mediterranean region.

在整个它的分布区有很多不同的比赛和生态型，更多的广布的特别是在地中海地区一般作为四倍体具本地二倍体比赛。

It can adapt to adverse terrestrial habitats and has evolved into different ecotypes. These stable reed ecotypes provide ideal experimental systems to study on plant resistance to external stresses.
