查询词典 maize mildew

The result showed that correlation coefficients of disease indexes between downy mildew and powdery mildew were 0.619 8 and 0.677 2 at the seedling and mature stages respectively, which were extremely significant. The correlation coefficients of downy mildew and powdery mildew for BC1P1 and F2 individuals from the cross between K8 and K18 were 0.492 5 and 0.493 3, and they were 0.497 6 and 0.286 8 for the cross of K10 with K18, respectively. These four coefficients were all extremely significant too. By AFLP analysis, E25M63-103 marker was linked to some susceptible quantitative gene controlling both downy mildew and powdery mildew. The finding proved further some resistant gene of downy and powdery mildews linked to each other from molecular level.

结果表明：在苗期和成株期，29份黄瓜材料的霜霉病和白粉病病情指数之间的相关系数分别为0.619 8和0.677 2，均呈极显著正相关；K8×K18组合的BC1P1和F2群体的霜霉病和白粉病病情指数之间的相关系数分别为0.492 5和0.493 3，K10×K18组合分别为0.497 6和0.286 8，均达到极显著正相关水平；采用AFLP分析，发现E25M63-103标记与控制黄瓜霜霉病和白粉病的某个数量感病基因紧密连锁，进一步从分子水平验证了黄瓜霜霉病和白粉病某个杭性相关基因是紧密连锁的。

Our work reported here are aiming at improving nitrogen and water use efficiency in wheat/maize, faba bean/maize, pea/maize and soybean/maize intercropping through field experiment.The main results obtained were as the following:(1) Land equivalent ratio was greater than 1.0 for faba bean (Viciafaba L.)/maize (Zea mays L.) intercropping regardless of nitrogen fertilizer application or not. Based on grain yields production, LER of pea (Pisum sativum L.)/maize intercropping was over 1.0 in spite of nitrogen fertilizer application, while LER was higher than 1.0 only when nitrogen fertilizer was applied based on biomass production. However, LER in soybean (Glycine max L.)/maize intercropping was smaller than 1.0 both nitrogen applicationa and no nitrogen application. In wheat Triticum aestivum L.

This developed a new material for the wheat virus-resistance breeding.In order to breed maize dwarf mosaic disease梤esistance maize species, the PAP gene was introduced into maize inbred strains and hybrid strains mediated by pollen and particle bombardment,10 transgenic maize plants were achieved and the PAP gene was indeed integrated into the maize genome by analysis of molecular biotechnological methods. The PAP gene in one of the transgenic maize plants had been transcription and translated, the ability of the virus resistance is undergoing.

为了解决玉米矮花叶病害的防治问题，采用花粉介导法及基因枪法将PAP基因分别导入玉米的杂交种及自交系，获得了10株转基因玉米，PCR及Southern-blot检测结果表明PAP基因已经整合到了玉米基因组中，并且其中有一株PAP基因已经得到了表达，病毒抗性鉴定表明转基因玉米能明显推迟玉米矮花叶病害症状的表现。

At the same time, there were complementation of water and nitrogen between spring-sown maize and summer-sown maize in the system of relay-planting. Spring-sown maize could get water and nitrogen from the summer-sown maize zone, and also the roots of summer-sown maize could touched to the regions of spring-sown maize to get water and nitrogen.

同时，套作体系中春、夏玉米存在对氮素和水分的互补利用，春玉米根系可以伸展到夏玉米区，而夏玉米也可以吸收利用春玉米区，从而达到养分与水分的互补利用。

Octoploid tritielytrigia type TAI-7045 showed immunity to yellow rust and middle resistance powdery mildew. CH-9916 is immune to yellow rust in seedling and adult stages, powdery mildew in seedling and adult stages, and their powdery mildew middle resistance. These suggested that the high powdery mildew-resistance in Octoploid tritielytrigia TAI-7045 had probably been transferred into common wheat.

通过对条锈病及白粉病抗性评价，结果表明：亲本八倍体小偃麦TAI-7045、小偃麦衍生系CH-9916对条锈病表现免疫，对白粉病表现中抗，而另一亲本"晋麦33"对条锈病、白粉病表现高感，推测小偃麦衍生系CH-9916抗条锈病及白粉病的基因均来源于代换的一对染色体——亲本八倍体小偃麦TAI-7045即来源于中间偃麦草。

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。

But when it came to different summer-sown maize, the straw of normal summer-sown maize absorbed less nitrogen absorption than grain did, while the straw of high oil summer-sown maize absorbed more nitrogen absorption than grain did. This it to say, high oil summer-sown maize need more nitrogen, when use N2, the nitrogen redundance was not happened, not like normal summer-sown maize.

但就各器官来说，普通夏玉米和高油夏玉米高氮时的表现有差异，前者全年籽粒化肥氮吸收量低于秸秆，而后者高于秸秆，表明高油夏玉米需氮量多，高氮时没有发生氮素冗余，而普通夏玉米却发生了氮素冗余，致使吸收的氮更多地残留在秸秆中。

In this paper we summarized the progress on molecular and genetic studies of maize downy mildew including genetic behave of resistance, QTL location of resistant gene, QTL effects and interactions between QTLs and environments, molecular marker and genetic diversity of resistance to maize downy mildew.
