查询词典 wheat-straw

Effects of water stress on the level of reactive oxygen speciesand activities of antioxidant enzymes in the leaves of wheat(Triticum durum Desf.) seedlings were investigated.Water stress resulted in significant increase in the contents of O-.2,MDA and the activities of superoxide dismutase and ascorbate peroxidase in wheat leaves.However,the activities of glutathione reductase,catalase and the content of H2O2 were not changed obviously under water stress.

分析了水分胁迫对小麦幼苗叶片中活性氧水平和抗氧化酶活性的影响，结果发现，水分胁迫能够显著提高超氧阴离子(O-2·)和丙二醛的含量及超氧化物歧化酶和抗坏血酸过氧化物酶的活性，而过氧化氢(H2O2)的含量及过氧化氢酶和谷胱甘肽还原酶的活性变化不明显。

PL1与PL2的氨基酸序列比较显示，在N-末端和重复区域同源性很高；两者的主要差别在于：C-末端PL1编码的氨基酸序列有一段富含Q、P的16个氨基酸残基的缺失。

The properties of isoelectric points of high-molecular-weight glutenin subunits in five varieties of common wheat and one variety of durum wheat were studied by two double-way electrophoresis techniques, IEF×SDS-PAGE and NEPEGE×PAGE.

运用IEF×SDS-PAGE和NEPEGE×PAGE2种双向电泳技术对5个普通小麦品种和1个硬粒小麦品种的高分子量麦谷蛋白亚基等电点的特性进行了研究。

The behavior of resistance of the most common Italian durum and bread wheat (80 and 73 cultivars, respectively) to wheat powdery mildew (Blumeria graminis f. sp. tritici) tested in the fields from 1992 to 1996, was reported. The experiments of adult resistance of these cultivars were conducted annually in about 13 different cereal growing areas.

本文介绍了意大利近年来小麦主要推广品种（80个硬粒小麦品种和73个面包小麦品种）1992～1996年在田间对白粉病的成株抗性情况，和13个意大利硬粒小麦和20个面包小麦品种及11个中国小麦品种用意大利10个主要菌系进行的苗期抗性鉴定情况。

Karnal bunt, or partial bunt, is a fungal disease of wheat, durum wheat, and triticale. Typically, only a portion of the kernel is affected

小麦印度腥黑穗病是小麦、硬粒小麦和小黑麦的一种真菌病害，典型表现为麦粒局部受感染。

It was showed that from a super-high yield germplasm HS Z6-06-56 derivated from an interspecific hybridization between common wheat and durum wheat: Dates of flagging,heading and maturing were 1,1 and 2 d earlier compared with its accepter′s parent of Shi 4185,respectively,there were no differences between traits of plant height,head length,spikelets/head by means of anova analysis.

通过对普通小麦、四倍体硬粒小麦种间杂交超高产新种质HS Z6-06-56性状表现分析表明：该种质与受体亲本石4185相比，挑旗期、抽穗期及成熟期分别提早1，1及2 d，株高、穗长、小穗数三性状等同于受体。

It indicated that a considerable degree of genetic differertiation has taken place in the A and B genomes of two species during evolution from wild emmer to common wheat.2 The similarities co-efficiency of A genome of common wheat and wild emmer was slightly higher than that of B genome.

野生二粒小麦与普通小麦A染色体组的遗传相似性高于两物种B染色体组的遗传相似性，从而说明小麦的不同染色体组在进化过程中的遗传速率或者说进化中的稳定程度是不同的。

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.

野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数，说明物种之间的杂交并不仅仅是染色体组简单的合并，其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

The common wheat line 3D256, a derivative of wild emmer with pedigree Yanda1817/WE27//Nongda015/3/941, is highly resistant to prevailing local wheat powdery mildew isolate E09 in Beijing area.

本研究利用来自以色列的野生二粒小麦WE27与普通小麦杂交，再用普通小麦连续回交和自交，育成高抗白粉病小麦新品系3D256（其系谱为燕大1817/WE27//农大015/3/941，F6）。
