Mol-1 of ozone are compared to those from the control run, indicating that from the heading to mature stage contents of chlorophylls a and b as well as the total increase first and then drop, but the carotenoid content and the value of value of chl a/b keep steadily rising and declinling, respectively, there is no significant decrease in the net photosynthetic rate and stomatic conductance during the early stage of heading but their drops increase gradually with prolonged smoking time.

mol-1的O3处理下，与对照相比，从抽穗期到成熟期冬小麦叶绿素a、叶绿素b和总叶绿素含量均呈先上升后降低的变化趋势，而类胡萝卜素的含量和Chla/b的比值则分别持续升高和下降，净光合速率和气孔导度在抽穗初期无明显下降，但是随着熏蒸时间的增加下降幅逐步变大。

Comparison of the coding regions of BH1-BH4 genes showed that BH1 had a lower sequence identity to other previously published B-hordeins than the other three B-hordeins obtained in this study. BH1 was then cloned in a bacterial expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid produced a 28.15 kDa protein in Escherichia coli. The potential value of B-hordein genes in grain quality improvement of hull-less barley has been discussed.

并且，在4个基因BH1～BH4中，BH1与先前报道的B组醇溶蛋白基因有较低的序列相似性，因此我们对BH1基因进行了原核表达，含该基因的表达载体在大肠杆菌中表达出相对分子质量为28.15 kDa并以包涵体形式存在的蛋白，进一步对其在青稞谷粒品质改良中的潜在价值进行了探讨。

The magnetic intensity of the applied magnetic force on a ferromagnetic material denoted by the term H measured in oersteds; b. The magnetic inducition or flux density as the flux per unit area normal to the direction of the flux ,denoted by B and measured in gauss; c. The magnetic permeability establishes the relation between magnetic induction and magnetizing force expressed as B/H =u; d.Residual magnetism or remanent magnetism which remains in the casting after the magnetizing force has been removed .
