子孢子

In plants that undergo ALTERNATION OF GENERATIONS, spores are produced by meiosis by the sporophyte generation, so are usually haploid; they germinate to produce the haploid gametophyte generation.

在具有世代交替的植物体中，由孢子体世代进行减数分裂产生孢子，因此多为单倍体。它们将发育为单倍体的配子体世代。

They reproduce asexually by means of zosspores or nonmotile spores and sexually by fusion of similar-looking gametes.

通过游动孢子或不能运动的孢子进行无性繁殖，通过相似的配子之间的融合进行有性繁殖。

A fertilized female cell or zygote, especially one with thick chitinous walls, developed from a fertilized oosphere.

卵孢子一种受精的雌性细胞或合子，尤指异配生殖产生的一种休眠孢子

A fertilize d female cell or zygote,especially one with thick chitinous walls,developed from a fertilize d oosphere.

卵孢子一种受精的雌性细胞或合子，尤指异配生殖产生的一种休眠孢子

But mutants showed no differences in growth, appressorium turgor, and virulence capacity to barley and rice CO39. 7. GFP controlled by mtp1 promotor was expressed mainly in hyphae and spores, less expressed in appressoria. mtp1 has no visible effects on the growth of rive blast fungus. However, it has significant effects on conidiation, conidium germination of the fungus.

mtp1启动子指导的GFP蛋白主要在稻瘟病菌的菌丝和孢子中表达，附着胞中表达量较少。mtp1基因对于稻瘟病菌的生长没有明显的作用，但对于稻瘟病菌的产孢、孢子萌发具有重要的作用。

The larger of two types of spores that give rise to a female gametophyte.

大孢子两种孢子中较大的一种，会产生雌性配子体

The smaller of two types of spores that give rise to a male gametophyte.

小孢子两种孢子中较小的一种，其产生一雄性配子体

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

Polysomes change in number as "few-many-few-many" during the development of the egg, early zygote stage, zygote at dormancy, zygote in prophase of mitosis and two-celled proembryo in sugar beet, which indicates that such changes in metabolism as "low-high-low-high" activity may relate to the transformation from gametophyte to sporophyte generation.

根据上述结果可以得出，栽培甜菜从卵细胞成熟→合子初期→合子休眠期→合子分裂前期→二细胞原胚的超微结构变化中多聚核糖体的变化最为显著，表现为&少→多→少→多&的数量变化过程，反映出细胞代谢状态也经历了&弱→强→弱→强&的变化过程，这种变化趋势与配子体世代向孢子体世代转变有关。

Additionally, the growth of the pathogen was obviously affected by cultural media. The morphological characters such as colony color and diameter, and production of fruit body of the fungus growing on PDA, 10% V8, apple leaves dextrose agar and apple leaves extraction dextrose agar media were different. The fungus formed colonies of about 8mm in diameter and did not produce fruit bodies and aerial hyphae in 1 month incubation on PDA. However it formed the similar size colonies as on PDA and produced fruit bodies and aerial hyphae on 10% V8 and LDA media in the same incubation period. Very small colonies (2mm in diameter) and fruit bodies were found on LEDA media in the same incubation condition. These results indicated that successful isolation of M. coronaria from apple leaves depended on suitable isolation method and cultural media as well as fresh samples.

不同培养基上菌落形态、大小和产孢情况差异也很大，培养1个月（25℃）后PDA上菌落黑褐色隆起，表面蚯蚓粪状，无气生菌丝，无子实体和基内菌丝；10% V8培养基上菌落中央隆起，黑褐色，表面生少量气生菌丝，边缘放射状，基内菌丝深褐色，有子实体；苹果叶片葡萄糖琼脂培养基上菌落平坦，黄褐色，表面生茂密的金黄色气生菌丝，基内菌丝深褐色，有子实体；苹果叶片煎汁葡萄糖琼脂培养基上菌落有明显的不规则隆起，黄褐色至黑褐色，表面生少许气生菌丝，菌落生长缓慢，无基内菌丝，分生孢子盘菌落表面生，菌落直径仅2mm左右，而在其他培养基上的菌落直径可达6－8mm，说明培养基质、分离方法均对苹果盘二孢的分离培养和生长发育有明显的影响。
