A prefix is often added, providing information as to the nature of the spore, for example conidiospores arise on a conidium, megaspores and microspores are the larger and smaller spores produced by heterosporous plants, etc.
此词前常有前缀修饰,用以提供含孢子特征的信息。例如 conidiospores 源于分生孢子, megaspores 和 microspores 是大孢子和小孢子,由具异型孢子体的植物体产生。

Microscopic examination showed the conidiophores were fasciculate and brown, and that the basal cell was enlarged and hemispheric. Well-developed conidia were long-obclavate, obtuse at both ends, with five to eight transverse septa, which indicated that the pathogen was Bipolaris setaria.
形态观察结果表明,该病原菌分生孢子梗丛生,褐色,基细胞膨大呈半球形,成熟的分生孢子长椭圆形,两端钝圆,具5~8个隔膜,表明其为狗尾草离孺孢。

In this paper, the biological characteristics of florescence, spikelet and inflorescences structure, morphogenesis formation of inflorescence, megasporogenesis and the development of female gametophytes were studied systematically by using anatomy structure, scanning electron microscopic and paraffin section methods. The results were as followed:(1) Phyllostachys praecox was the bamboo flowering fragmentarily; the cultivation changed the characteristic of flowering; the plantlets of flowering were complex and splitted into three kinds: the plantlet flowering before continued flowering; the plantlet flowering before stopped flowering and the plantlet changed into flowering. The inflorescence of Ph. praecox was indefinite inflorescence or called false inflorescence, and actually it was flower stress structure. Its basal unit was pseudospikelet with two kinds: apical spikelet and lateral spikelet. The floret had one lemma, one pelea, three stamens, one pistil and three lodicules.
本研究综合运用形态解剖学、扫描电镜、石蜡切片等技术手段,对雷竹花期生物学特性、小穗与花序构造、花序形态建成过程、大孢子发生与雌配子体发育等进行了较为系统的研究,结果表明:(1)雷竹为零星开花竹种,耕作条件对其开花特性具有重要影响;开花植株类型复杂多样,可以分为以前开过花现在继续开花、以前开过花现在停止开花以及以前未开过花现在转为开花等3种类型;雷竹花序为无限制花序或称&假花序&,实为花枝结构,基本单位为&假小穗&;假小穗有顶生和侧生之分;小花具内外稃各1枚,雄蕊3,雌蕊L,另具3枚大小不等之鳞被。

It"s vegetal mycelia were colorless, smooth, 1.2μm~3.0μm crude, manyconidiogenous cells born on vegetal mycelia, sometimes as many as a dozen,a very small number were single. The base of conidiogenous cell wasenlarged and many of them were bottle-shaped or spherical. The upper ofconidiogenous cell extended into a conidiogenous axis of 1μm wide and 14μm length which was the knee-bending ("Z like bending), there were small pectinae on the axis, conidium located on the small pectina.
营养菌丝无色,光滑,有隔,粗1.0μm~3.0μm,产孢细胞常浓密簇生于菌丝或泡囊上,有时可多达十几个,极少数单生,产孢细胞基部膨大,多为瓶形,近球形,颈部明显延长成粗1μm,最长达14μm的产孢轴,呈膝状弯曲,轴上具小齿突,分生孢子位于小齿突上。

zoospore:游动孢子
(1)游动孢子(zoospore):形成于游动孢子囊(zoosporangium)内. 游动孢子囊由菌丝或孢囊梗顶端膨大而成. 游动孢子无细胞壁,具1-2根鞭毛,释放后能在水中游动. (3)分生孢子(conidium)产生于由菌丝分化而形成的分生泡子梗(conidiophore)上,
