And Bauhinia purpurea could inhibit vibrio. And the extracts, extrated with petroleum ether from leaves of Melia azedarach L. and Bauhinia purpurea can inhibit Vibrio parahaemolyticus, too. The remainder extracts of Mangifera indica Linn.showed strong inhibition effect on Vibrio tubiashii. While the extracts of Eriobotrya japonica showed no inhibition effect.

结果 夹竹桃叶、芒果叶、苦楝叶和羊蹄甲叶4种中草药乙酸乙酯萃取部分对供试弧菌有很好的抑菌作用；苦楝叶和羊蹄甲叶石油醚萃取部分对副溶血弧菌有抑菌作用；芒果叶的水溶性部分对塔氏弧菌有很强的抑菌作用；枇杷叶提取物对4株弧菌均无抑制作用。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

The region between the circular brown band generated by cell lipid exosmosis and the band of the wound in the non-transgenic cotton Z35's leaves, is wider than that of the transgenic cotton T-34's leaves, and no micro-HR was found in Z35, the intensity of leaves wilting is much serious, by contrast, micro BR was found around the wound region within the transgenic cotton leaves inoculated with the pathogen, but the micro-HR was not found in the transgenic cotton treated with water and around wound region of non-transgenic cotton Z35 leaves which showed that there was micro-HR defence in transgenic hpa1xoo cotton.

棉花黄萎病菌侵染叶片后，非转基因棉花叶部伤口周围细胞无微过敏性反应，受病原菌侵染的叶片萎蔫程度较重；转hpa1xoo基因棉花叶部伤口周围细胞有微过敏反应，叶部刺伤处仅有较小的坏死斑，且不相连，发病较轻，而清水处理的转基因棉花与非转基因棉花叶片中伤口周围均无微过敏反应，说明病原菌侵染诱导转hpa1xoo基因棉花产生微过敏防御反应，转hpa1xoo基因棉花较非转基因棉花有较强的抗病性。

DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。

The differentiation states of costae indicates the ways they absorb and transport water, and their ability adapting to the dry conditions, which was elucidated by the following examples: Brachythecium plumosum, because of its thin cell-walls in the costae and the absence of hydrome, assistant and steroid cells, can absorb water and nutrition under shady and moist conditions; Plagiomnium rostratum, though often grows in shady and wet condition, has hydrome and steroid cells, a feature similar to those of xeric mosses, which endows it to grow in the conditions with periodical drought stress during its life cycle; Hygrohypnum luridum is characterized by its slender leaves with only one layer of cells, the thin cell-walls, the absence of filaments on the leaf surface, and the fewer layer cells in the costae, the absence of hydrome and steroid cells. These features make it adaptable to aquatic environments. For Pogonatum inflexum and Atrichum undulatum, their ventral surfaces covered with lamella, while for Racomitrium japonicum, Thuidium cymbifolium, Macromitrium ferriei, Diphyscium fulvifolium, Barbula unguiculata and Ceratodon purpureus, their leaves are strongly mammillose or papillos. Such appendiculate structures made them adaptable to thy conditions.

例如，荫湿生环境下的羽枝青藓Brachythecium plumosum，其中肋细胞胞壁较薄，无导水主细胞和副细胞的分化，也没有厚壁细胞分化，能够在阴湿环境下吸收水分和养分；钝叶匍灯藓Plagiomnium rostratum具有与旱生藓类植物相似的中肋结构，叶片较厚，中肋具导水主细胞，中肋背面具厚壁细胞，这些特点使该种藓类植物能够分布于间隙性干旱胁迫的环境中；水灰藓Hygrohypnum luridum叶片纤细柔弱，仅1层细胞，细胞胞壁薄，叶表无附属结构，中肋细胞层数少，无导水主细胞分化，也没有厚壁细胞，这些特点使得水灰藓'能够生长在水生环境中；东亚小金发藓Pogonatum inflerum和波叶仙鹤藓Atrichum undulatum的叶腹面覆盖着栉片，东亚砂藓Racomitrium japonicum、大羽藓Thuidium cymbifolium、福氏蓑藓Macromitrium ferriei、东亚短颈藓Diphyscium fuhifolium、扭口藓Barbula unguiculata和角齿藓Ceratodon purpureus的叶片表面有乳头状突起或疣状物，这些附属结构使它们能够适应于旱生的环境中。

Pseudoverticillata, but there was no significant change in Celtis wightii. There was no significant change in leaf area specific hydraulic conductivity K(subscript l between the two seasons in all the three species, which may caused by the adjustment in hydraulic architecture through partial loss of leaves during the dry season. In the dry season, maximum carbon assimilate rate A(subscript max was significantly lower than that of the wet season in all the three species.

除油朴的枝条边材比导率K(下标 s在旱季和雨季没有显著性差异外，尖叶闭花木和轮叶戟的K在旱季都有显著的降低；而枝条的叶比导率K(下标 l三树种在两个季节间均无显著变化。K在旱季没有显著性降低，可能是常绿树种在旱季通过脱落部分叶片以调整其水力结构来保持较高的单位叶面积的水分供应。

Results Two different ligations resulted in different changes in both morphology of hepatic roght lobe and signals on T1WI ,T2WI and DWI. In Group A, hepatic right lobes resulted in coagulation necrosis with no significant morphological change, but distinct hyperintensity on T2WI and DWI appeared. In Group B, after 24h and 72h of ligations, right lobes were atrophied and darkled, the rest lobes became hypertrophied.

结果 两种血流阻断法引起肝右叶形态及T1、T2及DWI信号发生了不同变化：A组肝右叶即发生凝固性坏死，体积大小无明显变化；T2WI及DWI上表现为明显高信号。B组术后24、72h后右叶体积变小，颜色变暗，左叶代偿性变大；T2WI上肝右叶为中等略低信号，T1WI呈略高信号，DWI上信号强度明显降低。

Finally, the pH value, lactic acid, water soluble carbohydrate, ammonia nitrogen and cellulose contents were determined for WH silage prepared under the suitable adding doses of lactobacillus and cellulase at day 1, 3, 5, 15, 25, 35 after ensilaging. The pH value decreased from 5.5 before ensiling to 4.3 on the 35th ensiling day, whereas the reverse change tendence was observed for lactic acid content. The cellulose content of silage was lower from 26.5%DM in raw material to 22.3%DM.

结果表明：pH值由青贮前的5.5至青贮第35天时降至稳定的状态，而乳酸含量的变化趋势相反；凤眼莲茎叶纤维素含量从未青贮前的26.5%干物质，至青贮第35天降至22.3%干物质，降低了约4个百分点；青贮料中可溶性碳水化合物的含量随青贮时间的延长而逐渐下降，但是在第5天到第15天的时间段里，可溶性碳水化合物的含量无显著性下降；氨态氮占总氮的比例从青贮第1天的4.61%显著上升至第5天的8.25%，而从第5天开始到第35天，氨态氮占总氮的比例上升的幅度较小。

Compared with progenies of inter-tree-pollinated E.urophyllaagain,progenies of self-pollinated E.urophylla showsignificant inbreeding depression in height,DBH and volume;theyshow no significant inbreeding depression in water content ofgreen wood,basic density and bark thickness;their content of1%NaOH extractives increases significantly,and their maturefiber length decreases significantly.

与尾叶桉株间杂交子代比较，尾叶桉自交子代的树高、胸径和材积具有显著至极显著的近交退化，生材含水率、木材基本密度和树皮厚度无近交退化现象，1％NaOH抽提物含量呈略显著性提高，成熟材纤维长度呈显著性减短；尾叶桉自由授粉子代的近交退化规律大致与自交子代相同，但其退化程度远不及自交子代。

It had more complications, longer course and treatment time and higher death rate, compared with the young people's pneumonia, which shows non-seasonal, typical clinical symptoms, the major type of lobar pneumonia, few complications, short progression and treatment course and better prognosis.
