孢子体的

Its mycelial is equal to the root of plants; its thalli are bole and branch of plants; its spore is plants' farina and seed.

它的菌丝相当于植物的根；菌体相当于植物的干和枝；孢子相当于植物的花粉和种子。

In vitro anther culture, experience shows that, in order to enhance the induction of regeneration, it is important to select appropriate developmental stage microspore vaccination.

This paper sums up the study history and present situation about moss spore germination and protonema developmemt, clarifying the important scientific significance.

本文综述了国内外对藓类植物的孢子萌发和原丝体发育过程的研究历史和现状，阐明了此项研究的重要科学意义。

In plant kingdom, having a protonema stage after spore germination is a specific character of moss and a marked difference compared with other plant group.

在植物界，孢子萌发后的原丝体发育阶段是藓类植物所独有的特征，也是该类群区别于其它类群的一个显著特点。

Result The detection limit of the two systems were 0.1fg, equal to 2.31×10^4 copies, which was 10^2-10^3 fold higher than conventional PCR. By the constructed detection systems, the TCK and Tilletia cariesTul could be distinguished. The teliospore and mycelium of TCK in the infected wheat plant tissue also could be identified accurately and rapidly.

建立的两套定量PCR检测体系的检测下限相当，可达到0.1fg，对应的拷贝数为2.31×10^4个，检测灵敏度比常规PCR高2~3个数量级，均可成功鉴别出TCK与小麦网腥黑穗病菌Tilletia caries (DC Tul， TCT，并可快速准确检测小麦矮腥黑穗菌冬孢子和检测罹病小麦植株体内的侵染菌丝体。

Their 95% effective concentration (EC95) value was 0.4735 μg/mL. Flumorph at the concentration of 0.5 μg/mL, can lead the inhibit rate of growth of mycelium, formulation of sporangium and germination of zoospore of Phytophthora sojae to 100%, the concentration was lower than Apron XL, Metalaxy which lead to the same inhibition rate. It indicated that Flumorph can obviously inhibit the growth of P.sojae in vitro, and effect is better than that of Apron XL and Metalaxy.

结果表明：氟吗啉对所测定的菌株4个发育阶段均有显著的抑制作用，氟吗啉对大豆疫霉菌菌丝生长EC50 值为0.1906μg/mL，EC95 值为0.4735 μg/mL；在0.5 μg/mL 浓度下对大豆疫霉菌孢子囊形成和孢子萌发抑制率达100%，低于达到相同抑制效果的金阿普隆和甲霜灵；说明该药剂在离体条件下能够有效抑制大豆疫霉菌的生长，效果好于金阿普隆和甲霜灵。

For the approach to the relations between the endangered situation and their sexual reproductive processes in Cimicifuga nanchuanensis, some comparative studies were made in C.simplex , a close and widespread species.

为了探讨南川升麻濒危与其生殖过程的联系。对广布近缘种单穗升麻进行了部分对照研究。论述单穗升麻的小孢子发生和雄配子体发育以及花药壁的发育。

The feasibility of the protoplast mutagenesis for increasing productivity was studied on a Claviceps paspali strain, which was not easy to produce conidia under laboratory conditions.

为了提高在一般条件下不易产生分生孢子的雀稗麦角菌的产碱率，对原生质体诱变育种的条件和方法进行了探讨。

The electron microscope scanning results showed that dense mycelia and conidial colonies were observed on the leaves of non K2SiO3-applied plants, while loosened mycelium or no mycelium on the leaf surface of K2SiO3-applied plants.

经电镜扫描分析显示，诱导接种后，未加硅酸盐的叶片布满浓密的菌丝体及分生孢子团，经硅酸盐处理的叶片上仅有松散的菌丝或者没有菌丝分布。

In the study, a set of near isogenic lines of CMS-S, S-Mo17Rf3Rf3 and S-Mo17rf3rf3, were adopted, and TdT-mediated dUTP nick-end labeling, in situ immunolocalization of cytochrome c and DNA ladder assay were employed to study the programmed cell death process on cytology and DNA level. The microscope observation evidenced that tapetal cells of fertile anthers kept intact until microspores, and then were disintegrated on later developmental stage.

S型细胞质雄性不育系的一对近等基因系S-Mo17Rf3Rf3 和S-Mo17rf3rf3为材料，采用TdT介导的dUTP DNA末端标记、细胞色素C免疫原位杂交和DNA寡聚核小体片段电泳等方法，分别在细胞学水平和DNA水平上研究了玉米CMS-S小孢子败育的细胞程序性死亡过程。
