子孢子

According to the formation of the apomitic embryos, apomixis could be divided into three major types: diplospory, apospory and adventive embryony.

按其胚体发生的途径，无融合生殖可分为二倍体孢子生殖、无配子生殖和不定胚生殖三种类型。

The apothecium forms spores called ascospores which are ejected into the environment. Most will fall on susceptible plants in the immediate area of the apothecia, but some can travel long distances by wind.

子蘘盘形成子蘘孢子并喷射到环境中，大多数会落到附近易感的植株上，但有些能够借助风的作用传播很远。

The spores of Neocheiropteris palmatopedate were cultured in improved Knop's medium, in-situ humus soil and red soil respectively. Spore germination and gametophyte development were observed under optical microscope and dissecting microscope, and the impact of four culture methods on the gametophyte development and sexual reproduction was compared. On these experiments, its cause of endangerment was analyzed.

采用改良Knop's固体培养基、原生境腐殖质土和红壤分别培养扇蕨孢子，光学显微镜及解剖镜下观察记录其于包子萌发及配子体发育过程，比较了3种培养方法对其配子体发育和有性繁殖的影响，并在此基础上探讨了扇蕨的濒危原因。

In this paper, we overviewed the relationship between male gametophytic selection and phenotype of its sporophyte, genetic differentiation and its application in plant genetic improvement, so it would be provided reference information for correlated research of male gametophytic selection.

本文主要概述雄配子体选择与孢子体表型的关系、遗传分化效应及其在植物遗传改良中的应用，以期为雄配子选择相关研究提供参考

If such gametophytes produce fertile gametes, the resulting sporophyte is then tetraploid, and large polyploid series may subsequently be developed.

如果这种配子体能够产生可育的配子，那么形成的孢子体通常是四倍体，这样就可以得到大量的多倍体。

The inheritance of poly-eggs in the crosses between APⅣ,IR36,MinghuiNo.77 and Longtepu B was examined.It was concluded that the production of poly-egg is probably controlled by gametophytic genes,rather than by sporophytic genes.

通过APⅣ与IR36、明恢77和龙特浦B杂交研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因决定的，而是由配子体基因决定的，属配子体遗传的范畴。

The inheritance of poly-eggs was investigated by crossing and reciprocally crossing APIV with monoembryonic rice variety IR36,Minghui No.77 and Longtepu B,respectively.It was suggested that the production of poly-eggs is probably controlled by gametophytic genotypes,rather than sporophytic ones.

通过多胚水稻品系APⅣ与单胚水稻品种IR36、明恢77和龙特浦B正反杂交，研究APⅣ的多卵遗传行为，表明APⅣ的多卵性状可能不是由孢子体基因型决定的，而是由雄配子体基因型决定，属配子体遗传的范畴。

In culture, spores germinated two weeks after sowing. Gametophyte development is of the "Marattia" type. Gametophyte shape changed from circular, to cordate, to branched. Antheridia and archegonia appeared 10 and 12 months, respectively, after spores were sown.

培养时其孢子在洒播二周后开始发芽；配子体以「观音座莲舅」型发育，配子体生长过程由圆形转心脏形再形成分支。

Pebrine disease has increased in recent years,so it is the two grand requisites of theoretics and production to do research on microsporidia.

家蚕、柞蚕微孢子虫是引起家蚕和柞蚕微粒子病的病原，微粒子病对养蚕业来说是一种毁灭性的病害。

The detected phenolic, gallic acid was gradually increased with continuous cropping years increasing, vanillic was steady in soil of different continupus cropping years, ferulic acids had more content in soil of five-year continuous cotton cropping, but remarkably reduced with ten-year continuous cropping.7 It was found that the p-hydrobenzoic, vanillic, gallic acid and ferulic acids in different comentration inhibited/stimulated the spore germination and mycelium growth of cotton verticillium wilt.

没食子酸含量随着连作年限增加在土壤中逐渐增加，香草醛在不同连作年限土壤中含量较稳定，而阿魏酸连作5年土壤中含量最高，连作10年时显著下降。7不同浓度的对-羟基苯甲酸、阿魏酸、香草醛和没食子酸对棉花黄萎病病菌孢子萌发和菌丝生长产生促进或抑制的化感作用。
