查询词典 alloplasmic

In order to produce a good F1 hybrid variety in wheat, it is necessary to explore a new male-sterile cytoplasm and its nuclear restore gene. Four alloplasmic male sterile lines of wheat with Aegilops cytoplasm were developed to identify mitochondrial DNA variation that could potentially be associated with cytoplasmic male sterility.

在杂交小麦选育中，为了更好地利用细胞质雄性不育性，研究与不断挖掘新的不育细胞质类型及其对应育性恢复基因以改良现有不育资源至关重要。

Using Aegilops crassa cytoplasm wheat as test material, salt tolerance of alloplasmic wheat was identified by tissue culture, nutrient solution culture and artificial saline pond, from calli, seeding stage, recovering stage and mature period.

以粗厚山羊草肠胃细胞质小麦为材料，采用组织培养、水培、模拟盐池等方法，研究情绪肠胃细胞质对小麦耐盐性的遗传效应。

Using Aegilops crassa cytoplasm wheat as test material, salt tolerance of alloplasmic wheat was identified by tissue culture, nutrient solution culture and artificial saline pond, from calli, seeding stage, recovering stage and mature period.

以粗厚山羊草细胞质小麦为材料，采用组织培养、水培、模拟盐池等方法，研究细胞质对小麦耐盐性的遗传效应。

CMS as sterile cytoplasm of-ferer and Chinese cabbage as its accepter,the alloplasmic male sterility line CMS3411-7 in Chinese cabbage have been obtained by interspecies cross and continuedbackcross with Chinese cabbage 3411-7,so 3411-7 was its maintainer line.

CMS3411-7是以甘蓝型油菜Polima不育胞质为供体和大白菜自交系3411-7杂交后，再以3411-7为轮回亲本，经多代回交后得到的含有Polima胞质的异源胞质雄性不育系，3411-7就为其相应的保持系。

The 75kD polypeptide in SDS-PAGE about all protein in eight isonuclear alloplasmic and allonuclear isonuclear male-sterile lines had been found keeping close with the male sterile.

对8 个同核异质、同质异核不育系和相应保持系进行花药全蛋白SDS-PAGE，发现了75kD多肽与雄性不育关系密切。

Nineteen alloplasmic common wheats whose origins of cytoplasm are Aegilops and nuclear donor F94-111 were taken as study materials, the flag leaf area, net photosynthetic rate of flag leaf were measured and relative Chl. content of flag leaf, and genetic effects of Aegilops cytoplasm were studied. Ae. Squarrosa, Ae.

以19种不同山羊草细胞质异质系与其核供体普通小麦F94-111为材料，测定其旗叶叶面积、净光合速率和叶绿素相对含量，研究不同山羊草细胞质对普通小麦光合性状的遗传效应。

The many hybrid wheat combinations were bred by 4 male sterile types of alloplasmic wheat with Ae.kotschyi,Ae.variabilis,Ae.ventricosa and Ae.bicornis cytoplasms and some restoring lines,and their seed qualities were analysed.

利用具有粘果山羊草(Ae.kotschyi)、易变山羊草(Ae.variabilis)、偏凸山羊草(Ae.ventricosa)和二角山羊草(Ae.bicornis)异源细胞质小麦雄性不育系(以下简称粘、易、偏和二角型)组配成不同组合的杂种小麦，研究这4种不育系对杂种小麦籽粒品质的影响。

The frequency of cells with univalent at MI and with lagging chromosomes and chromosomal bridge at A I in PMC of F1 hybrids of 4 alloplasmic 1BL:/1RS and non-1BL/1RS wheat male sterile lines with Aegilops kotschyi,Ae. variabilis,Ae.ventricosa and Ae.bicornis cytoplasms were systematically investigated,and the relationship between FCU at M I,FCLB at A I and F1 selfed seed set was analyzed.

系统调查了4类异质(粘果、易变、偏凸、二角山羊草细胞质)1BL/lRS、非1BL/1RS小麦雄性不育系与其恢复系杂种F减数分裂中期Ⅰ出现单价体细胞频率，以及后期Ⅰ出现落后染色体和染色体桥细胞频率，并对中、后期染色体变异率与杂种F自交结实率进行了相关分析。
