囊孢子的

After meiosis the ascus contains four or eight haploid ASCOSPORES that are liberated through a pore at the end of the sac.

减数分裂后，子囊内含有四个或八个单倍体的子囊孢子并且在囊泡的顶端开口处释放出来。

Although the megagametophyte formed and even the double fertilization had been finished 70 days after pollination at normal temperature, the megasporogenesis had not yet been finished at low temperature.

低温(12-18℃)处理的蝴蝶兰，授粉50d开始分化胚珠原基、60 d胚囊处于大孢子母细胞时期，比常温(20-25℃)下的推迟10-15 d；授粉70 d，常温下的蝴蝶兰植株已完成雌配子体发育和双受精，而低温处理的蝴蝶兰仍未完成大孢子的发生过程。

Compare with Zygomycetes which produce sporangiospores inside a sporangium.

而接合菌的无性孢子是在孢子囊内产生孢囊孢子。

Species delimitation in halophytophthora is based mainly on the morphology of zoosporangium, the presence of vesicle or/and plug, and the mode of zoospore release.

目前halophytophthora有15个种和2个变种，而其分类是依据游动孢囊的形态及游动孢子的释放机制。

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.

平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比，平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊，之后多数有性胚囊萎缩、退化而败育，只有极少数进一步发育；而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体；经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争，多数胚珠只有一个无性胚囊成熟。

Based on the security,efficacy,cheapness and easy gain three disinfectant drugs(acids, degerming agents,surface active agents)were chosen to killing coccidial oocysts in chicken.

本试验按照安全、有效、经济、来源容易的原则，从对鸡球虫卵囊有一定抑杀作用的三类消毒药物(酸类、消毒剂类、表面活性剂类)中，筛选了 17组不同药物和浓度的搭配组合，设计了 3个试验：抑制鸡球虫新鲜卵囊孢子化试验；抑杀孢子化卵囊试验；新鲜卵囊和孢子化卵囊经药物处理后感染小鸡试验。

Some of these spores in the sporangium After the mitotic generated, such as clothes swimming algae spores, Rhizopus spores of the cyst, chlorella-like pro-spores, etc.; some spores in the sporangia produced in the future through meiosis, such as Ulva lactuca , kelp, to money, gourd moss, fern and so on.

其中有的孢子是在孢子囊中经过有丝分裂所产生的，如衣藻的游动孢子、根霉的孢囊孢子、小球藻的似亲孢子等；有的孢子是在孢子囊中经过减数分裂以后产生的，如石莼、海带、地钱、葫芦藓、蕨等。

It is a saclike structure that is formed either singly or in large numbers in ascomata.

子囊：在子囊菌中产生孢子的器官，它是一种囊状结构。

Molecular studies have identified some genes participating in this process, including those regulating anther cell division and differentiation, controlling male meiosis, supporting pollen development, and promoting anther dehiscence.

分子生物学的研究已经发现了一些参与这一过程的基因，包括控制花粉囊组织的分化、小孢子母细胞的减数分裂、小孢子的发育和花药的开裂等。

Yeasts, ascospores and the asexual spores of moulds are slightly more resistant than the vegetative

酵母、囊孢子和霉菌无性孢子的耐热性不及活细菌，杀菌温度通常在65 ~ 100°C之间。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
