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。

Regeneration frequency varied obviously with genotypes,suggesting that the genotype is one of the important factors to the regeneration of shoot apex.

不同基因型的茎尖再生频率有很大差异，说明基因型是影响茎尖再生的一个重要因素。

Factors affecting transformation of shoot apex mediated by Agrobacterium tumefacien were also optimized.

对农杆菌介导高粱茎尖转化的因子进行了优化，获得较高转化频率的条件为：茎尖预培养时间3D，在OD600值为0.5农杆菌菌液中感染10MIN，共培养3D。

This suggests that shoot apex is most sensitive to water stress and the ~(14)C-photoassimile distribution likely shifts from above-ground to root, being benefit to maintaining root growth and tolerance to water stress.

这表明茎尖对水分胁迫非常敏感，同化物向茎尖的运输受到抑制，运积重心由地上部转到地下部，从而有利于保持根系在胁迫条件下的生长，提高植物的抗旱性。

The amount ofethylene release by shoot apex and root showed no difference between iron-deficient treatment and control plants above before the appearance ofrelatively high reductase activity,which indicated that ethylene may not playa direct role in regulation of root ferric reductase activity,and the inhibitionof which by〓and〓may be caused by other reasons.

缺铁处理植株茎尖和根系乙烯释放量的测定结果显示，三种植物中，缺铁与对照植株的茎尖及根系所释放的乙烯可能不直接参与缺铁根系还原酶的调控，〓和〓对缺铁根系〓还原酶活性的抑制可能是其它原因所致。

The content of IAA synthesized in shoot apex and diffusible IAA of irondeficient bean plant was higher than that of control plant on the 1st day afterFe-deficient treatment,and content IAA in shoot apex increasedcontinuously afterwards.

缺铁处理菜豆植株茎尖的内源IAA及扩散型IAA在处理后第1天就明显高于对照，且在以后的几天中茎尖中内源IAA持续增加。

There isn't apparent rule on effects of low temperature and its duration to seed clove on pseudo-stem diameter of garlic cv.

蒜种处理温度和蒜种低温处理时间对改良蒜和苍山蒜假茎粗的影响无明显规律。3 个品种处理间假茎长变化规律不明显。

YaJin-11: Sweet sorghum crossbred with the growth period between 128 and 135 days. Purple seeding, 3.26 meters high, stem diameter of 2.31cm, sugar Brix between 17 % and 23%,loose ear; ear length of 22.5cm, per-mu grain yield of 300kg with the weight of 18.3g and per-mu yield of 5600kg; Resistant to leaf disease, insect and pets and lodging.

雅11号是甜高粱与甘蔗成功杂交而成，该品种幼苗紫色，株高3.26米，生育期128-135天，主茎粗平均2.31厘米，茎杆糖锤度17%-23%，散穗，穗长22.5厘米，千粒重18.3克，成熟期子粒产量每亩可达300公斤，总生物每亩产量5600公斤，抗叶病，抗黒穗病，抗虫，抗倒伏。

Results1 , The glossopharyngeal nerve exits the skull through the jugular foramen posteromedial to the styloid process and the styloid muscle with Vagus Nerve and Accessory Nerves.

结果1、通过对尸头进行解剖发现舌咽神经在颅底茎突和茎突诸肌的中后部与迷走神经、副神经一起自颈静脉孔出颅。

Gibberellic acid (GA3) had no effect on elongation of shoot and differentiation of leaves, but enhanced the dried weight of shoot.

赤霉素(GA3)对银杏茎尖伸长生长和叶片分化没有促进作用，但随着GA3浓度提高，茎尖干物质增加。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
