查询词典 sterile

The results showed that : three species all can resistant to drought ,wind-drift sand and endure to sterile soil, and with fine adaptability to local condition that there are irrigation in growth phase and no irrigation in post-vegetative phase in 2002 and there are no irrigation in growing period and irrigation in after bearing phase in 2003. Among the three species ,Agropyron cristatum× A.desertorum cv.

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 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。

Methods: After anesthetization, left eye of each 18 New Zealand rabbits (2.0～2.5 kg) was alkali burned by circum-type filter-paper soaked in 1mol/L NaOH for 1 min under sterile conditions.

18只新西兰兔(2.0～2.5kg)麻醉后，每只选左眼无菌条件下用1mol/L NaOH浸透的环型滤纸片与角膜密切接触1min建立角膜碱烧伤动物模型。

Stamens many to rarely few (9), in [3 or]4 or 5 bundles that are free and antipetalous or variously connate, with filaments variously united or apparently free and then sometimes sterile; anther dehiscence longitudinal.

雄蕊多或有时少(9个)，[3-] 4-5 束，束簇离生并对瓣，或不同程度合生，花丝不同程度联合或明显离生，有时不育；花药纵裂。

Ovary 2-locular, carpels free at apex; ovules mostly 1 per carpel, less often many, but then most of them sterile, crassinucellar, bitegmic, anatropous, halfway between apotropous and epitropous, pendent from ovary top if solitary, along the carpellary margins if numerous; placentation axile.

子房2室，心皮离生在先端；每心皮多数的胚珠1，较少的通常很多，中途在apotropous和胚珠向上转之间，然而他们中大多数不育，crassinucellar，bitegmic，倒生，中轴胎座花柱和柱头2。

Microscopic observation on anther development process of cytoplasmic male sterile line"1815A"showed that its anther development was inhibited at the stage of archesporial cell differentiation.

以1815A不育系对应的保持系1815B作对照，对不育系进行细胞学观察，结果表明：随着花蕾的发育，败育的雄蕊一直处于孢原细胞时期，不能形成花粉囊并产生花粉母细胞，但雌蕊和维管束组织发育正常。

The content of GA exhibited on imbalance in different tissue of seedling. The content of IAA, GA and ZR of male sterile lines were lower than maintainer lines to some degree, especially in the stage of archesporial and meiosis. IAA, GA and ZR are the important plant hormone which regulates lots of activity of plant. Their deficient must interfere on the development of anther and result in abortion.

在花期叶片激素含量在保持系和不育系之间变化较大，蕾期不育系的IAA、GA和ZR含量出现不同程度的亏缺，尤其是从小蕾期到大蕾期阶段，ogura不育系、改良萝卜不育系的IAA、GA和ZR含量都极显著低于保持系IAA、GA和ZR是植物体内重要的信号物质，可调节植物的多种生命活动，其亏缺影响花粉的正常发育，从而引起败育。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
