查询词典 callose

Sometimes, a few of pollen tubles could enter into styles through stigmas, but abnormal callose could deposit in the tubes.

结果表明，诸葛菜花粉很难在3种类型油菜的柱头上黏附和萌发，同时在花粉黏附的部位及其附近柱头乳突细胞内产生大量胼胝质；萌发的少量花粉粒，其花粉管生长迟缓，且发生严重扭曲、肿胀等畸形现象，从而导致其进入柱头也比较困难；少数花粉管能穿过柱头进入花柱，但时常有异常胼胝质沉积在花粉管中。

There was noevident cause-effect relationship between the formation and theamount of callose and the recognition reaction of theincompatibility.A great deal of ester was secreted.from pollenfuurow in 30 minutes after pollination,and the ester covered stigmaand pollens.The secretion sustained about two hours.

用扫描电子显微镜在授粉后间隔不同时间跟踪观察了亲和性授粉和不亲和性授粉的花粉与柱头相互作用的特征和特性，观察结果发现，在授粉30分钟内，花粉粒开始从花粉沟向外分泌大量脂类物质，覆盖柱头和花粉粒，分泌作用大约持续2小时结束。

The breaking parts of anthers in the four longerstamens were face to the reverse side of pistil and winding,but thedevelopments of the self-compatibility lines were regular.A greatdeal of callose was observed in stigma and pollen tuber both in theself-compatibility and self-incompatibility pollination.

对亲和性授粉和不亲和性授粉的荧光显微观察表明，无论是亲和性授粉还是不亲和性授粉，在柱头组织和花粉管组织中均可以形成大量的胼胝质，未发现胼胝质的产生和数量与自交不亲和性的识别反应有什么因果关系。

Staminode tube usually short; staminodes white, occasionally tinged or marked with purple; outer staminodes 2, petaloid, obovate, exceeding corolla lobes; cucullate staminode with median or subterminal appendage; callose staminode obovate, apex petaloid.

退化雄蕊管通常短；退化雄蕊白色，偶尔微染或者用紫色标明；外部退化雄蕊2，瓣状，倒卵形，超过的花冠裂片；兜状的退化雄蕊有中间或者近顶生附属物；胼胝质退化雄蕊倒卵形，先端瓣状。

The cortical cells had thin walls and mitochondrium, and nucleus wassurrounded by chloroplasts, and vesicles were next to cell plasmalemma. However, cellwalls of velamen, cortex and exodermis in the mycorrhiza of D. nobile had ring orpapillary thickenings in many cases. The hyphae were surrounded by moremitochondria and vesicles of plant, and the hyphae were digested and their structure waschanged at last. The cell wall of endodermis also had typical ring thickenings, and manysieve orifices in sieve tube elements of phloem were covered by callose, while therewere liaison cords in a few sieve orifices.

金钗石斛菌根的根被细胞的细胞壁多处出现环形圈，外皮层细胞壁加厚，木质化，也有环形圈存在，皮层细胞细胞壁多角形明显，加厚，皮层细胞中存在被消化、失去结构的真菌菌丝，在菌丝周围有较多的线粒体、小泡，内皮层细胞的细胞壁呈现的典型的加厚及木质化环形圈，韧皮部筛管的筛板结构，绝大多数筛孔已为胼胝质所覆盖，仅个别筛孔中还存在连络索。

Pollen morphology of the Chinese monotypic genus Dichotomanthes and its out-group Prinsepia utilis were investigated from the point of view of pollen development. The SEM observation revealed that there is not any change in morphology and sculpture of pollen grains from the young pollen grain seperated from callose of tetraspore to the mature pollen grain in Dichotomanthes tristaniaecarpa. Only the volume of pollen grain increased with maturity.

从发育的角度研究了中国特有单种属Dichotomanthes Kurz及与其系统学研究有关的外类群Prinsepia utilis的花粉形态，扫描电镜观察显示Dichotomanthes花粉粒自脱离四分体胼胝质膜开始至成熟二核花粉粒不同发育时期，花粉形态和外壁纹饰未见变化，仅花粉体积随成熟度增加而有所增大。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
