轴根

Under the optical microscope and SEM, uniaxially well-aligned sub-microfibers were observed spanning across two adjacent bars. The overall appearance was like a spider web.

通过光学显微镜以及电镜观察可以发现，沿单轴定向排列的亚微米纤维横跨于两根临近不锈钢棒中间，整体外观与蜘蛛网相似。

Compared with the conventional take-off and landing F-35A already flying, the F-35B has a shaft-driven lift fan mounted behind the cockpit, roll ducts installed in the wing and swivelling nozzle fitted to the engine.

与已经试飞的常规起降型F-35不同的是，F-35B在紧靠驾驶舱后面装有轴驱动升力风扇，发动机装有可偏转尾喷管，每侧翼根处各有一个发动机引气反作用阀。

The effects of different concentrations of Cr(superscript 6+)(0, 10, 20, 50, 100 mg/L K2Cr2O7) on the content of Pro, malondialdehyde, membrane permeability, activities of protective enzyme SOD and POD in roots and epicotyls of maize seedlings were studied.

研究了不同浓度(0， 10， 20， 50， 100mg/L K2Cr2O7)Cr(上标 6+)胁迫对玉米幼苗根和上胚轴中脯氨酸和丙二醛含量、细胞膜透性、超氧化物歧化酶及过氧化物酶等保护酶活性的影响。

The results were as the follows: with the rising of Cr(superscript 6+) concentration, the Pro content in both root and epicotyls was first up and then down; the content of MDA and membrane permeability increased continuously; SOD activity deceased gradually and POD activity was first up and then down.

结果表明，随着Cr(上标 6+)胁迫浓度的增加，根和上胚轴中Pro含量呈先升后降的趋势，MDA含量和细胞膜透性则持续递增，SOD活性逐渐下降，POD活性先升后降。

Epicotyls were cutted longitudinally and cultured in the dark first,on the MS basal medium with 3 mg/L 6-BA and 30 g/L sugar,100% adventitious shoot induction and an average of 33.8 shoots per explant were obtained.The base of the adventitious shoots was treated with 1000 mg/ L IBA for 10 min,then placed onto the filter papers which ends dipped into liquid medium with...

上胚轴纵切结合前期暗培养，在MS附加6-BA 3mg/L、蔗糖30g/L培养基中，不定芽诱导率为100%，每个外植体平均诱导的不定芽数达33.8；不定芽在1 000mg/L IBA溶液中浸泡10min后，移入1/4MT+1/2MT+10g/L蔗糖的液体培养基中，采用滤纸桥法进行培养，生根率达100%，平均根数2.5条；移苗成活率达100%。
