植物的节

This research used genetic engineering techniques to insert hsf8 gene to dicotyledon expression vector pCAMBIA3300 that contains the selection marker gene bar. And pCAMBIA 3300-HSF8 has been transfered into new soybean lines Hajiao5337 and Hajiao5489 by A grobacterium tumefaciens.

本文将热激转录因子8(hsf8)基因构建在植物表达载体pCAMBIA3300电以大豆子叶节作为受体，通过农杆菌介导法将hsf8基因导入品质性状优良的两个高产大豆新品系哈交5337和哈交5489中，最后获得转基因植株。

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。

No one knows exactly which variety of clover was the shamrock St. Patrick used.

没有人知道圣帕特里克节上的三叶草确切是属于苜蓿类植物哪一品种。

The study on the development and reproduction of B-biotype Bemisia tabaci on four cucurbitaceous host plants, i.e., cucumber, hairy gourd, bitter cucumber, and sponge gourd, showed that the one generation development duration of B.

研究了B型烟粉虱在4种葫芦科寄主植物黄瓜、节瓜、苦瓜和丝瓜上的发育和繁殖特性。

The earliest May Day celebrations appeared in pre- Christian , with the festival of Flora , the Roman Goddess of flowers, and the Walpurgis Night celebrations of the Germanic countries.

五一节庆祝活动最早出现于前基督教的，有节的植物，罗马女神的鲜花，五朔节夜庆祝活动的日耳曼国家。

In the present study, large internodal cells of Chara Corallina were used as as a model system, distribution and coordination environment of lanthanum cells as well as the effects of lanthanum on absorption of mineral nutrients were studied.

本论文工作以模式植物珊瑚轮藻的大型节间细胞为材料，研究了稀土元素镧在细胞中的分布、结合状态以及镧对植物矿质元素吸收的影响。

In this paper, the bio-ecological characteristics of indigenous halophytes: Salsola implicata, Suaeda linifolia, Halocnemum strobilaceum and Kalidium foliatum will be studied in order to explore the mechanisms of plants tolerance and to get the theory and measures for treating salt soil and applying halophytes.

本文拟通过对生长于盐渍化土地上的四种常见盐生植物：盐爪爪、盐节木、亚麻叶碱蓬和密枝猪毛菜的生物生态学特性的研究，查明盐生植物适应盐渍化土壤的机制，为在盐渍化土地上恢复、重建和扩展植被，并为改造该类土地提供依据。

Primary Study on Salt Adaptability of Suaeda linifolia ;2. In this paper, the bio-ecological characteristics of indigenous halophytes: Salsola implicata, Suaeda linifolia , Halocnemum strobilaceum and Kalidium foliatum will be studi.

本文拟通过对生长于盐渍化土地上的四种常见盐生植物：盐爪爪、盐节木、亚麻叶碱蓬和密枝猪毛菜的生物生态学特性的研究，查明盐生植物适应盐渍化土壤的机制，为在盐渍化土地上恢复、重建和扩展植被，并为改造该类土地提供依据。

Any of numerous plants of the widely distributed genus Polygonum, characterized by stems with knotlike joints and conspicuous sheathlike stipules.

蓼属植物一种分布广泛的蓼属植物，特征是茎干上带有球状突节和明显的套状托叶

Red light can also reduce gibberellin content, which minishes internode length and plant height; however, far red light (700 -800 nm) can have the opposite affect and enhance GA.

光同时是植物形态形成的信号源。600~700nm的红光能降低植物体内赤霉素的质量分数，从而减小节间长度和植株高度；而700~800nm的远红光能提高体内赤霉素的质量分数，从而增加节间长度和植株高度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
