1)  unpollinated ovule
未授粉胚珠
1.
The new sugar beet triploid variety with anther culture-Zhongtian huapei1(original combination code91-5-1),crossed with male homozygous diploid which came from unpollinated ovule of K-5and female tetraploid plant C-87.
甜菜花培新品种—中甜花培1号(原组合代号91-5-1)是以K-5的未授粉胚珠培养得到的纯合二倍体株系作父本,与四倍体品系C-87作母本杂交育成的花培三倍体新品种。
2.
The regenerated plants of monosomic addition line M14 of sugar beet wasacquired from unpollinated ovules, and then genetic relationship between theregenerated plants and the parental plants was analyzed by performing AFLP, thus themode of reproduction of M14, obligate apomixis or facultative, was identified by meansof molecular biology.
利用甜菜单体附加系M14品系未授粉胚珠培养获得再生植株,采用AFLP技术分析再生植株与亲本植株之间的亲缘关系,从而用分子生物学手段鉴定M14品系的生殖方式是专性无融合生殖还是兼性无融合生殖。
2)  Unpollinated ovule culture
未授粉胚珠培养
3)  unfertilized ovule of triploid
三倍体未授粉胚珠
4)  False fertilized ovule
假授精胚珠
5)  Unpollinated ovules
未受精胚珠
1.
【Method】Unpollinated ovules from summer squash ovaries were cultured on N6 medium and supplemented with 2,4-D,NAA,BA.
方法将西葫芦未受精胚珠接种至附加2,4-D、NAA、BA的N6培养基上可形成胚状体,该胚状体转接至无激素的N6培养基上可形成再生植株。
6)  undeveloped ovules
未发育胚珠
1.
The undeveloped ovules in mature fruits of Bingtangcheng(Citrus sinensis) were cultured on five different media to induce embryogenic calli.
以冰糖橙成熟果实中的未发育胚珠为外植体 ,培养诱导胚性愈伤组织并进行植株再生。
2.
The undeveloped ovules of mature fruit of Bingtang orange (BT) are used as explants to induce embryogenic callus and establish the embryogenic cell line in this experiment.
为了诱导冰糖橙的愈伤组织和建立胚性细胞系,以冰糖橙成熟果实中未发育胚珠为外植体,将乙烯合成抑制剂AgNO3应用于冰糖橙胚性细胞系的建立,AgNO3设有5,10,12mg/L等3个处理,以未加AgNO3的MT培养基为对照。
补充资料:胚珠
分子式:
CAS号:

性质:即卵(细)胞。出现于形成雌性配子的高等植物(裸子植物和被子植物)的一种结构物,它由一个带有一个或两上包膜的短带所组成,包膜内附有露出由不完全封闭的小孔(珠孔或卵孔)的珠心(孢子体组织的细小物质)。在珠孔末端的单个细胞增大变成大孢子叶,经减数分裂产出大孢子。这种大孢子接着又产生胚胎囊,并产生裸子植物的藏卵器或被子植物功能必珠配子胞核。受精以后,卵细胞成熟形成种子。
