查询词典 maize cob

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。

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。

Starch in the silk and cob has the single apex, too. But the peak value was showed in different time between cob and silk: silk in the 5th, but the cob in the 3rd after silking.

The difference in yield, its components, basic characteristics such as mean size and bare tip length of cobs, plant height, base internode diameter, secondary root number per plant, LAI and DMW at the same measuring date, between the three treatments were insignificant respectively; the optimized fertilization made the three leaves around corn cob rather smaller, the cob leaf slightly thinner, a decrease of the cob leaf chlorophyll content at greater rate at the later stage, and dry matter accumulation amount slightly reduced from flowering to grain filling.

在优化施肥、秸秆还田优化施肥及传统施肥条件下，夏玉米穗长、穗粗、秃顶长、株高、基部伸长节间粗度、单株各层次生根条数、同一时期的叶面积指数和干物质积累量无显著性差异。在优化施肥条件下，夏玉米棒三叶总叶面积略微减少，穗位叶叶片略微变薄，生育后期穗位叶叶绿素含量下降稍快，吐丝-收获的干物质积累量略有下降。

The result indicated, the CIMMYT forage characteristics of the overgrowth, strong tillerity and high yield could inherit to the offspring ,and the inherit ability was higher. It was obviously difference of seedling, plant, and its grow habit, flower apparatus and seed between CIMMYT forage and common maize. The hybrid offspring of CIMMYT forage and common maize keep the strong trait of growing and development, but the flower and seed character were look like common maize. The backcross offspring were not different to common maize besides with some tillers, distinct multi-ear and atavism.
