有性生殖

The results demonstrated that sexual reproduction capacity between isolates derived from ascospores and conidia were different, and at least partially determined by their genetic differences.

结果表明，由子囊孢子和分生孢子萌发获得的菌株的有性生殖能力具有显著差异，这可能决定于不同的遗传特性。

In this paper, the sexual reproduction capacity of Orbiliaceous anamorphs derived from ascospores and asexual conidia were evaluated.

本文评估了分离自子囊孢子和分生孢子的圆盘菌科无性型有性生殖能力。

In some cases it has been possible to 'connect' the anamorph name with the teleomorph name - but in many others this has not yet been done and may never be possible because the organism may have lost the ability to reproduce sexually.eg teleomorph genera, Nectria and Gibberella, both have anamorphs which have been classified in the anamorph genus Fusarium

有时将有性与无性联系容易，许多情况下难甚至做不到，因为有的菌丧失了有性生殖的能力。30 000种已知的子囊菌只有5 000种与无性态挂上了勾，结果往往是杂乱的，如有性阶段的丛剌壳属和赤霉属的无性阶段都是镰霉属。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。

In C. reinhardtii, isogamous sexual reproduction occurs through "plus" and "minus" mating types.

C。 reinhardtii藻的同配有性生殖通过&正&配子和&负&配子结合产生。

Juglans mandshurica is one of the most important component species of the mixed forest of the broadleaved species and Korean pine forest in the eastern mountains in Northeast China.

胡桃楸是东北东部山地阔叶红松林的重要组成树种。以胡桃楸个体有性生殖过程为研究对象，通过定株定枝调查，研究了胡桃楸芽种群分化、物候及散粉规律、果实生长发育过程及环境影响因子。

Nosema disease is a kind of zoonoses, of all ages can be affected by pollution, for human carinii infection and host immune function of severely inhibited closely related to people before that Nosema without sexual reproduction period .

微孢子虫病是一种人兽共患病，各年龄组均可受染，人类为孢子虫感染与宿主的免疫功能严重地受到抑制有密切关系，以前人们认为微孢子虫无有性生殖期。

As a sexual reproductive organ, ovules have received much attention by botanists. Since the nineteenth century, the morphology, structure, ontogenesis, origin and molecular biology of angiosperm ovules have been studied in detail.

胚珠作为被子植物的有性生殖器官一直为植物学家所关注。19世纪以来，人们从形态结构、发生发育、起源及分子生物学等方面对胚珠进行了大量的研究。

There were generally reproductive growth in each age class ramets of Carex kirganica as well as that in Scirpus planiculmis. Furthermore, the more or less of the reproductive allocation was certain and that is the result of reproductive trade-off and the adaptation to their habitats.

长秆苔草和紧穗三棱草各龄级分株均进行有性生殖，并保持一定量的生殖分配大小，是适应生境的生殖策略权衡的结果。12个不同水分梯度生境芦苇生殖分配RA Ⅰ为5.82％～16.31％，生殖生长比率Rrg为10.68%~16.35%，2个生境毛芦苇RAI分别为9.09%和13.98%，生殖生长比率分别为22.07%和1 8.06%。

Reproduction in lichens may be asexual by soredia (algal cells enclosed by fungal hyphae) or by sexual fungal spores, which can survive only if some algal cells are also present.

地衣可以利用粉芽进行无性生殖或利用真菌孢子进行有性生殖。
