研究结果表明：每个花药具备4个花粉囊，花药由表皮、药室内壁、中层、绒毡层组成，成熟后中层和绒毡层都解体；四分体属左右对称型，花粉属2-细胞型花粉粒；在进行花药培养时取蕾标准应为3-4mm左右。关键词：铃兰；花药；解剖

The RGCMSplants in RGCMS-117A or S45A were complete male sterile at the bothtemperature conditions,and there was no pollen sac differentiation at thehigher temperature condition and there were 1-3 pollen sacs in each anther atthe lower temperature condition,but the anther development was inhibited atthe stage of microspore.

表现核质不育的植株，在高温条件下表现彻底波里马细胞质雄性不育，无花粉囊分化；在低温条件下，也表现彻底雄性不育，具核、质不育的共同特点，每个花药可分化出1-3个花粉囊，但无可育花粉，其雄性败育时期和特点与S45A和117A相同。

对水稻亚种间杂种及其稳定的多胚品系SB-1进行了细胞学、胚胎学和遗传学研究，主要结果如下：1、影响杂种低结实率的因素包括胚囊败育、花粉败育、花药不开裂和雌雄性器官发育进程不一致。

Inflorescence an axillary heads; flowers bisexual, petals5, white, ribbon-like,1.5 cm long; stamens5, filaments very short, anthers ovoid, with2 pollen sac opening each by2 vertical valves, connectives exserted; staminodes5, bifid.

头状花序腋生，花两性，花瓣5，白色，带状，长1.5厘米；雄蕊5，花丝极短，花药卵形，具2个各2瓣裂的花粉囊，药隔突出；退化雄蕊5，叉状分裂。

Cytoembryological studies were employed to reveal theorigin of haploid and to determine the cytological factersrelating to the production of diploid polyembryony withinone embryo sac occurring in natural population of apolyembryonic line SB-1 of O.sativa.

SB-1自然群体中的单倍体来源于助细胞无配子生殖。细胞胚胎学研究表明，卵器中的一个或两个助细胞能在受精之前发育成胚，其发生率分别为观察子房数的2.24%和1.75%。

The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

胸膜面浅层的微血管网稀疏，深层的胸膜下微血管网致密；胸膜面浅层的微血管与小叶间隔的微血管之间相互移行，与胸膜下微血管之间形成吻合连接；根据胸膜下微动脉连续分支的顺序，常可将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管四级；胸膜下毛细血管网主要以网络状的形式存在，但在铸型上均可见数量不等的"小孔状"结构；低倍镜下肺实质内微血管网呈现大小不等、形态各异的蜂窝状结构，可以见到由微血管网构成了肺泡、肺泡囊、肺泡管和呼吸性细支气管以及终末细支气管等结构的轮廓。
