objective the effects of anthocyanin pigment from maize purple plant on resisting lipid peroxidation were investigated.methods the inhibition of anthocanin pigment from maize purple plant was examined in vitro that autcoxudation of lecithin liposome system induced by fe2+.50 mice were randomly divided into 5 groups.vehicle and different dose anthocyanin pigment from maize purple plant were given respectively,and then experimental injury of mice liver was induced to make use of bromobenzene and the content of mda was determined in liver homogenate.results the inhibition rates of anthocyanin pigment from maize purple plant on linoleic acid oxidation was higher that of ascorbic ascorbic acids.the content of mda in homogenate in middle and high dose of pigment were significantly lower than that in low dose and the injured control group.there were no significat differences in the content of mda in homogenate between low dose group and injury control group.conclusion the anthocyanin pigment from maize purple plant have the capability to resist lipid peroxide.

目的 探讨玉米紫色植株色素抗脂质过氧化的作用。方法体外实验测定玉米紫色植株花色苷色素在fe2+引发的卵磷脂脂质体体系中抗氧化活性。体内实验，取50只小鼠随机分成5组，分别给予溶媒和不同剂量的色素，然后采用溴代苯致实验性肝损伤，测定肝匀浆的丙二醛含量。结果在由fe2+引发的卵磷脂脂质体体系中玉米紫色植株色素对脂质过氧化有明显的抑制作用，抑制率随样品的浓度增高而增大，并且明显优于抗坏血酸。在溴代苯致小鼠实验性肝损伤模型实验中，中、高剂量组的丙二醛含量均低于损伤模型组。低剂量组和损伤模型组比较丙二醛含量差异无统计学意义。

Twenty-three isolates of gray leaf spot pathogen, Cercospora zeae-maydis, collected from growing area of Northern China were clustered based on their soluble protein and isozyme profiles obtained through native PAGE in order to base physiologically the pathogen differentiation at protein or isozyme level.

利用聚丙烯酰胺凝胶电泳技术，对采自北方玉米主产区的23个玉米灰斑病菌菌株进行可溶性蛋白质和同工酶电泳图谱分析及聚类分析，从蛋白质和酶学的多态性水平上分析玉米灰斑病菌的生理分化特征。

A set of maize inbreds or cultivars were firstly screened as GLS(Cercospora zeae-maydis)pathogen differential hosts with genetic background which current cultivars shared in China,such as inbreds Shen137,78599-1,Mo17,748,C8605-2,E28,598,Va35,K12 were identified as major ones,and cultivars Shenshi29, Shenshi31,Tiedan9,Yedan13,Dan413,Danyu18,Shennong87,Dongdan54 as affiliated ones.

There was no significant effect of U0126 on the filamentous growth and condial production of the 10 tested fungal plant pathogens: S. turcica, Curvularia lunata, Cochliobolus sativus, Fusarium oxysporum, Alternaria solani, Coniothyrium diplodiella, A. alternata, A. porri, Botrytis cinerea and A. brassicae, but the inhibitor can strongly inhibit the spore germination of S. turcica, A.

在PDA培养基上，U0126对玉米大斑病菌、玉米黄斑病菌、小麦根腐病菌等10种植物病原真菌的菌落形态和生长速度没有显著影响，可以形成正常的菌丝、分生孢子，但U0126处理的玉米大斑病菌分生孢子萌发时间晚，芽管短，分生孢子的萌发百分率下降。U0126对分生孢子萌发的抑制程度随着浓度增加而上升，但随着处理时间的延长而下降。

Through comparison of energy inputs in corn fuel ethanol life cycle,fossil energy inputs of corn production and ethanol conversion processes were identified as the most important,and therefore nitrogen fertilizer,electivity and diesel used in corn farming and energy consumption of distillation and dehydration process in ethanol production could be known as the most influential factors for the energy benefit of corn fuel ethanol.

但是玉米燃料乙醇从原料的生产、乙醇的转化，一直到被燃耗的整个生命周期中的多个阶段需要直接或间接地消耗矿物能源，因而，虽然玉米燃料乙醇是可再生能源，然而是否具有可持续性及可持续性的大小则取决于其燃耗中所产生的能量与燃料乙醇整个生命周期中所消耗的能量相比是否有盈余及盈余的大小。20世纪70年代中期，玉米燃料乙醇的能量平衡问题研究首次在美国出现[2，3]，当时乙醇替代汽油的能量效益的有关研究指
