胚珠的

Style filiform, terete or somewhat tetragonous; stigma capitate, not exserted; ovary 4-parted; ovule anatropous.

有点的花柱丝状，圆柱状的或4棱；柱头头状，不外露；子房4分开；胚珠倒生。

Ovary 3-loculed, or reduced to 2-loculed; ovules 1 to several per locule, orthotropous. Fruit a loculicidal, 2- or 3-valved capsule, rarely baccate and indehiscent.

子房3室，或者2室；胚珠每室1颗到多颗，直生；果为室背开裂，2-3瓣裂的蒴果，很少为不裂的浆果。

Ovaries 2, free or basally connate; ovules 2-6, biseriate on each side of a prominent placenta.

子房2，离生或基部合生；胚珠2-6，在一突出的胎座的每边双列。

Carpels united by a filiform style; ovules numerous, biseriate on each placenta.

通过一种丝状的风格的心皮合生；胚珠多数，在每胎座上双列。

Ovary 15- or more loculed; ovules 1 per locule, erect; styles as many as locules; stigmas decurrent, filiform.

子房15的或更多室；胚珠1每室，直立；同数的花柱子房室；柱头下延，丝状。

On the base of review the research development in tissue culture and genetic transformation, Comparative analyses were made on the callus induction and embryogenetic abilities of anther and non-pollinated ovules of rubber tree. Fluorescence detection was implemented with the different in vitro material of Hevea brasiliensis.

本研究在综述了橡胶树组织培养及遗传转化研究进展的基础上，系统地比较了橡胶花药和未授粉胚珠愈伤组织诱导及体细胞胚胎发生能力，对橡胶树不同离体组织进行荧光背景检测，将在植物胚胎发育时期起重要作用的BBM基因导入橡胶树，对电激法转化游离小孢子细胞以及农杆菌介导花药愈伤组织进行初步探索。

In a compatible pollination, pollen germinates to extrude a tube that penetrates the stigma and grows extracellularly through the stylar tissues to ovules.

当花粉通过自交不亲合的筛选后，萌发的花粉管会穿透柱头并沿著花柱朝胚珠生长。

The effect of pollinators on the plant sex allocation, may be a new fied to study the evolution of hermaphroditic plants.

传粉者对花粉和胚珠配置的潜在影响，可能为研究两性花的进化打开一条新路。

RT-PCR analysis showed that GhMADS1 gene expressed in petals, stamens, ovules and fibers, but not in roots, stems, leaves, bracts and sepals. The strongest expression of GhMADS1 gene was detected in petals. But in floral buds of a cotton homeotic mutant (CHV1), whose floral organs are all converted to bract leaf-like organs, the transcript of GhMADS1 gene was not detected.

RT-PCR分析显示，该基因在陆地棉的花瓣、雄蕊、胚珠和纤维中表达，特别是在花瓣中表达量最高，而在根、茎、叶等营养器官和棉花同源异型突变体CHV1（所有花器官均变为苞叶状叶性器官）的变异花蕾中不表达。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
