无胚的

Studies on genes related to embryo and endosperm development are leading us to an extensive understanding of the mechanisms of seed development and apomixis at the molecular level, which will benefits the research for yield and quality improvement of plant seeds via genetic engineering.

对胚和胚乳发育相关基因的研究，可使人们在分子水平上解析种子发育和无融合生殖的分子机制，更有效地开展植物种子产量和品质改良的基因工程。

We studied effects of different hormones and combination on buding and rootting of Citrus reticulata Blanco epicotyl in tissue culture.

椪柑无菌苗上胚轴为实验材料进行离体培养，研究了不同种类的激素及其组合对椪柑上胚轴出芽及再生芽生根的影响。

There were no significant difference amongedifferent adult skin fibroblasts on the cleavage and development of reconstituted embryos.

研究发现来自不同个体的皮肤成纤维细胞所构建的重组胚，卵裂率和囊胚发育率无差异。

Past study re-sults had indicated that MMC in the apomictic type could at most develop to te-trad stage.We observed that the sexual embryo sac of"Pingyi Tiancha"coulddevelop into 4-nuclei embry sac.

前人只观察到无融合生殖类型的大孢子母细胞至多能发育到四分体时期，而我们观察到平邑甜茶的有性胚囊能发育到四核胚囊。

Seed vertical or horizontal, orbicular; testa membranous or subleathery; embryo spiral; perisperm absent.

种子垂直或水平，球状；种皮膜的或近革质；胚螺旋形；外胚乳无。

Seed horizontal or vertical, lenticular, reniform, ovoid, or globose; testa thinly leathery or membranous; embryo green or whitish, planospiral, slender; perisperm scant or absent.

种子水平或垂直位置，透镜状，肾形，卵球形，或球状；种皮薄革质或者膜；胚绿色的或带白色，平面螺旋状，纤细；外胚乳不够的或无。

Seed horizontal, globose or ovoid, depressed, slightly emarginate near hilum; testa membranous, glabrous; embryo slender, annular; perisperm not copious.

水平的种子，球状或卵球形，下凹的，靠近种脐稍微缺；种皮膜，无毛；胚纤细，环状；外胚乳不丰富。

Results indicated that semidried mei preserved by reused brine or regenerated salt have higher values in acid, soluble solids, and salt contents than those prepared from fresh salt. However, there is no significant difference in sensory evaluation. These results implied that the reuse of waste brine is feasible.

研究结果显示以废液再腌渍的梅胚在可滴定酸含量、可溶性固形物含量、盐度等方面均较高，但官能品评方面则无明显差异，因此将废盐液重复使用於梅胚腌渍的构想初步可行，且再生盐亦可於二次腌渍时利用。

Stamens numerous; anthers elliptic to oblong; filaments linear. Follicles 5--40, sessile, sometimes stipitate, with branching transverse veins, styles distinct or nearly absent; ovules several to many.

花瓣无；雄蕊多；花药椭圆形到长圆形；花丝线形蓇葖果5-40，无梗，有时具柄，具分枝横向脉，花柱离生的或近无；胚珠数枚到多数。

Light microscope combined with stereological methods were used to observe and analyze renal tissue and corpuscles at different developmental stages in vivo and vitro.

结果 胚龄12天（E12）体外培养发育情况与在体无显著差异，其余各组随胚龄的增加，小鼠肾组织的体外发育呈下降趋势。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
