Adventitious buds were directly induced from the surface of epicotyl explants under the condition with the combinations of IBA 0.1 mg/L and BA 0.2-0.7 mg/L. Of which IBA 0.1 mg/L and BA 0.5 mg/L induced the highest regeneration frequency.

结果表明，在IBA O.1 mg/L与BA 0.2～0.7 mg/L组合的条件下，不定芽从上胚轴外植体的表面直接被诱导分化，其中以在MS+IBA 0.1 mg/L+BA 0.5 mg/L上的诱导率最高。

The results were as the follows: maize inbreeds were sensitive to salt stress;different salinity stress had inhibition effects on the germination rate,shoot length,relative water content and net photosynthetic rate;different inbreed had obvious difference in salinity tolerance;the best one was XS98-28;the next was XSK5;the middle were in turn XSF,XS01-61;the lower were other inbreeds.

结果表明：玉米对盐胁迫非常敏感，不同盐浓度均对玉米芽苗期的发芽率、胚根长度、叶片相对含水量及净光合速率产生抑制作用；不同材料间耐盐性存在明显差异，各指标均能反映出不同材料的耐盐性；通过鉴定筛选，14个材料中，耐盐性极强的为XS98-28，耐盐性较强的为XSK5，耐盐性中等的为XSF，XS01-61，其余材料耐盐性均较弱。

The deduced amino acid sequences of HbHDT1 showed high identities (65％, 59％, 50%, 45%, 43％ and 40%, respectively)to those of the histone deacetylase from Ricinus communis, Populus trichocarpa, Solanum chacoense, Trifolium pretense, Glycine max and Triticum aestivum.

该氨基酸序列与蓖麻、毛果杨、马铃薯、红花苜蓿、大豆、小麦的HDACs家族成员的同源性分别为65％、59％、50％、45％、43％和40％。半定量RT-PCR分析结果表明HbHDT1在巴西橡胶树的花、愈伤组织、胚、叶、芽、胶乳中均有表达。

Taking leaf and hypocotyl of Limonium bicolor as the explant, the system of rapid propagation were established, the influences of hormone concentration to induce the tissue culture and adventitious buds were studied.

方法］以二色补血草的子叶与胚轴作为外植体，建立快速繁殖体系，研究不同激素浓度对诱导愈伤组织、不定芽以及生根率的影响。

A systematic study was made on the induction of callus from terminal bud, cotyledon, plumular axis and the regenerated plantlets from terminal bud in Camptotheca acuminata Decne, and a large number of calli and cluster buds were obtained.

系统研究了以喜树顶芽、子叶、胚轴为外植体诱导愈伤组织的培养方法和以顶芽为外植体快速繁殖喜树的方法，获得了大量的愈伤组织和丛生芽。

Sepals completely united in bud, splitting into 2 at anthesis; stamens free or all basally united; fasciclodes absent; ovary 2-loculed, each locule 2-ovuled; leaf venation densely and prominently reticulate with translucent gland dots in areoles.

萼片完全合生在芽中，分成2在花期；雄蕊离生或全部基部合生；下位腺体缺席；子房2室，每的子房室2胚珠；在小窠里的浓密和显著的叶脉网状的具半透明的腺体小圆点。 7 Mammea 格脉树属

Dicots such as tobacco and tomato do not have the PF40 homolog gene, but we found its homolog gene maybe present in Arabidopsis genome.

Northern杂交结果表明PF40基因可以在谷子的各个部位及各个时期表达，但在芽与胚轴中有很高的表达。

As well as enhancing the specification of distal lung epithelium, this protocol was found to yield cells with a phenotype most closely resembling that of lung-committed progenitor cells present in the foregut endoderm and the early lung buds during embryonic deelopment.

除了提高末梢肺上皮的数量，这一个方法被发现产生了在胚胎发育期间最接近表达在前肠内胚层和早期肺芽表型的细胞。

The Plant tissue raise is the plant sterile culture technology, has the totipotency theory according to the vegetable cell, the use plant body exsomatize organ (for example root, stem, leaf, stem point, flower, fruit and so on), the organization (for example cambium, epidermis, cerebral cortex, marrow department cell, endosperm and so on) or the cell (for example big spore, small spore, somatic cell and so on) as well as the protoplast, in aseptic and suitable artificial culture medium and illumination, temperature and so on under artificial condition, can induce injuries the organization, not to decide the bud, the adventitious root, finally forms the complete adult plant the discipline.

植物组织培养即植物无菌培养技术，是根据植物细胞具有全能性的理论，利用植物体离体的器官(如根、茎、叶、茎尖、花、果实等)、组织（如形成层、表皮、皮层、髓部细胞、胚乳等）或细胞（如大孢子、小孢子、体细胞等）以及原生质体，在无菌和适宜的人工培养基及光照、温度等人工条件下，能诱导出愈伤组织、不定芽、不定根，最后形成完整的植株的学科。

The results indicated that heartbeat stage of sea perch embryo, tail bud stage of Japanese flounder and turbot embryo were suitable developmental stages for cryopreservation.

三种海水鱼类胚胎的毒性耐受力实验结果表明：无论是用methanol，还是用PG处理鲈鱼不同发育时期胚胎，都是心跳期胚胎的成活率最高；牙鲆和大菱鲆尾芽期胚胎在20％的PM32混合抗冻液中成活率分别为87％和78.55％，分别高于其原肠中期、胚孔封闭期、心跳期、出膜前期胚胎的成活率。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
