As a result penicillium of Ma Erni humble is double photograph bacterium, mould bacterium colony can discover the broom shape mycelial of diagnostic sex,; of pigment of rose of water-solubility of the generation after sanded Paul fosters 3 days is medullary inside and outside of cell of blood of the week outside mixing all can discover spore;PAS coloring sees bacterium body show circle, elliptic or sausage shape, size is differ, it is 2~8 μ M about, color of afterbirth wall incarnadine and clear and successive, it is thus clear that inside the cell of sausage shape one apparent horizontal stroke is lain between, afterbirth is qualitative not easy and chromatic.

结果马尔尼菲青霉菌为双相菌，霉菌型菌落可发现特征性的扫帚状菌丝，沙保罗培养3天后产生水溶性玫瑰色素；骨髓和外周血细胞内外均可发现孢子；PAS染色可见菌体呈圆形、椭圆形或腊肠状，大小不一，约为2~8μm，胞壁染红色且清楚连续，在腊肠状的细胞内可见一明显的横隔，胞质不易着色。

The morphological analysis of strain EMZY-1 showed that it was a straight rod, about 0.3×1.7 in size, and spherical and terminal spore appeared. Results of physiological and biochemical test showed that strain EMZY-1 was a Gram-positive bacteria, and could not grow when temperature was lower than 10℃ or higher than 60℃, pH was lower than 5.0 or higher than 12.0, and the concentration of NaCl was more than 10%. The strain EMZY could grow on the medium as a of sugar, glucose and mannite. The strain could use saccharose, glucose and mannitol as carbon resource, and NH4(superscript +) and NO3(superscript -) as nitrogen resource.

通过对该菌株的形态、培养特征、生理生化特征的研究以及16S rDNA序列分析表明：该菌株为革兰氏阳性菌；细胞为棒杆状，端生孢子，大小约0.3×1.7；温度低于10℃、高于60℃无明显生长；pH低于5.0、高于12.0无明显生长；NaCl质量浓度达到10%菌株不能生长；能在蔗糖、葡萄糖、甘露醇为C源的培养基上生长；NH4、NO3为菌株良好N源。

In the early period of ovary development of Castanopsis delavayi, the size of ovules relative to the ovary cavity is small and rich trichomes can be found before the development of the megaspore mother cell.

高山栲在子房发育的早期胚珠在子房中占有的体积相对小，在大孢子母细胞发育前子房中已经有丰富的毛被。

The division and regeneration of nori cells on solid ...

从某种程度上看固体培养下的再生产物和液体培养下相似，正常的体细胞能再生为正常苗，畸形苗，壳孢子以及较多的细胞团等。

The results were as follows: 1.Inoculated on the induction medium at the late uninucleate stage,the microspores could initiate embryogenesis by first divisions in both symmetric and asymmetric patterns,but the former was predominant.

通过观察玉米小孢子胚胎发生的细胞形态学特征，发现：离体培养条件下单核后期的花粉可以通过均等分裂和不均等分裂两条途径形成胚状体，与前人的研究结果一致。

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。

It was proved that low concentration Fe2+ can acce lerate its growth and development,but high Fe2+may lead to seedlings defor mity, make the cells become small and the seedlings divide into monospores again and again.

结果表明，低浓度的 Fe2+能促进其生长发育；而高浓度的Fe2+可以导致苗大量畸变，细胞变小，苗反复崩解成单孢子。

These abnormal cells became dramatically vacuolated and hereafter disintegrated completely at later stage.

这类异常的小孢子母细胞在随后的发育中逐渐液泡化并最终解体。

Objective To investigate the intervening effects of Ganoderma spore on the decrease of cell proliferation and neuronal survival in the hippocampus of fetal and postnatal rats induced with gestational hypertension.
