In thistreatment,some embrocyte,which may originate from the nucellus cell,can be foundin few of ovaries in APⅣ.The embryos in most of ovaries in APⅣ and IR36develop normally,but the endosperm,in which many crystal-like substances wereobserved,by spike-spray with 2,4-D 3-hours after pollination.

少数APⅣ子房的"腔"内出现多个"胚状体"，推测可能来自珠心细胞的分裂；在受精后处理的大部分子房胚胎发育正常，但胚乳发育却不正常，胚乳内观察到许多的结晶体。

Ovary superior, 1-loculed, or divided by 3 septa and 3-loculed, or incompletely septate; ovules 3 and inserted at base of ovary, or numerous and biseriate on 3 parietal placentas.

Ovary ovoid, 5-7 × 3-5 mm; styles 4.5-5(-7) mm, 0.7-0.8(-1)× as long as ovary, free, suberect, outcurved near apex.

Bisexual flowers: stamens 1 or 3, inserted on 1 side of ovary; filaments inconspicuous; connectives conspicuous, if stamens 3, connectives connate at base or free; anthers 1- or 2-loculed, longitudinally dehiscent; pistil 1, 1-carpelled; ovary inferior, 1-loculed; ovule 1, pendulous, orthotropous; style short or absent.

两性花：雄蕊1或者3，在子房的1侧着生；花丝不显著；药隔显著，如果雄蕊3，药隔在基部合生或离生；室花药1或2，纵向开裂；雌蕊1，1心皮；子房下位，1室；胚珠1，下垂，；花柱短或无。

子房半下位两性花子房的纵切面，为下方与托杯组织愈合的子房部分，外方细胞较大的为托杯的组织，内方为子房，两者间形成较明显的界线。

The infection of rhizobia to rice was a dynamic process beginning with surface colonization of the rhizoplane (especially at lateral root emergence), followed by endophytic colonization within roots, and then ascending endophytic migration into the stem base, leaf sheath, and leaves where they developed high populations.

同时，根瘤菌还可以沿植物的表面从根到地上部分迁移。在植物的生殖生长阶段，内生根瘤菌仍然保持活动性，可以进入烟草子房的子房壁、胎座和胚珠内，暗示根瘤菌通过种子向子代垂直传播的可能性。

By removed ovary culture after positive and negative hybridization, produced interspecific hybridization, and have improved the hybrid seed through removed ovary culture and induced to shoot by culture medium MS, and produced hybrid F1, the plant of Brassica junce×B.pekinesis, the advantage characteristic of hybrid plant is similar to female nature;By cytology authenticating, chromosome number of F1 young flower bud cell (2n=28), it is the sum of monoploid chromosome number of female parent Brassica junce(2n=36) and male parent B.pekinesis(2n=20); The hybridization to Brassica junce×B.pekinesis, and embryonic bud come from removed ovary culture, and it found another form of plant embryo saving.

以芸薹属植物芥菜型油菜和白菜为研究对象，对其进行常规正反杂交后子房的离体培养，通过离体子房培养获得的杂种种子经MS培养基诱导成苗，获得了芥菜型油菜与白菜的杂种F1代植株，表现出杂种优势；通过细胞学的方法，鉴定了杂种F1幼蕾体的细胞染色体数为2n=28，为母本芥菜型油菜（2n=36）和父本白菜（2n=20）的单倍体染色体数之和；芥菜型油菜与白菜常规杂交后，经离体子房培养获得了&胚性芽&，确立了植物胚挽救的另一种形式。
