孢子囊

Indusium The flap of tissue, derived from the placenta, that encloses the developing sporangia in the sorus of a fern.

囊群盖：是一种起源于胎座的瓣片状组织，覆盖在蕨类植物孢子囊群中正在发育的孢子囊上。

Fern species are usually distinguished by their leaf shapes, venations, scales, sporangia, and indusium, etc.

蕨类又分为真蕨和拟蕨两类；前者孢子囊生长在叶片，包括一般常见的蕨类；后者的孢子囊长在茎干上，包括其他石松科、卷柏科、水韭科及木贼科。

The sporulated oocyst holds 2 sporocysts and each sporocyst contains 2 sporozoites,i.e.each oocyst contains a total of 4 sporozoites.

新排出的未孢子化卵囊培养后可观察到孢子化的卵囊，内含2个孢子囊，每个孢子囊内含有2个折光性较强的子孢子。

Germination rate of sporangium in different temperature, pH and nutrition was examined with suspending-drop method.

用悬滴法测定温度、营养和 pH值对孢子囊萌发的影响，用硫酸法控制小容器相对湿度和载玻片法测定湿度对孢子囊萌发的影响。

The results showed short peptide LD-1 can have a well inhibiting effect on the sporangium germination of Pseudoperonospora cubensis and have a certain teratogenic action on the development of the germ tube of sporangium.

结果表明：短肽LD-1对黄瓜霜霉病菌孢子囊萌发具有较好的抑制效果，且对孢子囊芽管发育具有一定的致畸效果。

The temperature for pathogen sporangium to germinate and to release moving spore is 5～35oC,the optimum temperature is 10～20oC.Under suitable temperature, the sporangium germinate and release moving spore within 2 hours, water film is the essential for sporangi...

霜霉病菌孢子囊萌发释放游动孢子的温度范围为5～35℃，最适为10～20℃，在适宜的温度范围内2小时孢子囊就可释放游动孢子；孢子囊必须在水膜中才能萌发；在供试的碳源中，孢子囊在乳糖液中萌发最好；在供试的氮源中，孢子囊在硝酸铵液中萌发最好；孢子囊萌发的pH值范围为4.5～9.0，最适为8.5。

Result and Conclusion :All of them and their different dosages were effective to control conidia of Peronospora arborescens.

结果和结论：室内药效测定结果表明不同浓度的供试药剂均能使孢子囊出现畸形，其中以普力克对孢子囊的致畸能力最强，甲霜铜、甲霜铝铜和靠山对孢子囊的致畸能力较弱。

De Bary were tested and the morphological change of sporangia was observed under microscope. The results showed that spore germination rate was closely related to ozone concentrations.

de Bary孢子囊萌发进行了试验，结果表明：臭氧水处理对孢子囊萌发的影响与臭氧水浓度密切相关，以9 mg/Kg臭氧水处理1 min可以抑制95%以上孢子囊萌发，以18 mg/Kg臭氧水处理1 min则100%抑制孢子囊萌发。

The main characters of this category are: 1 It possesses clear main axes and lateral branches/sporangial stalks; 2 Sporangia terminate the lateral branches or long stalks; 3 With the distinct dehiscing mechanism, the sporangia have the variation in shape, i. e. reniform, rounded or vertically elongate; 4 Primary xylem is of centrarch maturation; 5 Conducting tracheid is G-type.

该类群包括Hsüa，Renalia，Nothia，Sartilmania和Huia，其主要特征为：1）具有明显的主茎轴及侧出的分枝系／孢子囊柄；2）孢子囊顶生于侧枝上或侧生的长柄上；3）孢子囊性状存在变异，为肾形、圆形或纵向伸长，具明显的开裂机制；4）初生木质部发生顺序为心始式；5）G-型输水管胞。

Results:(1) The conchosporangia of brown yellow mutant was smaller and mature time was 15 days later than the parents. Thallus grew slowly in early stage, but average daily growth rate reached (7.50±1.18) cm after blade length was over 60 cm.(2)The emerald conchocelis were easy to mature and had special developmental mode that the spherulocytes can directly develop into sporangial branchlets and conchosporangia without thick conchocelis stage. Emerald blades were low in RPE with just (6.4710±0.0184) mg/g dry mass. The thallus grew quickly, average daily growth rate reached (11.95±2.33) cm after blade length was over 60 cm.(3) The conchocelis filaments of breen mutant were thin and short. Thallus grew slowly and had low contents of three phycobiliprotenin and chlorophyl.

实验进行50d。结果：(1)褐黄色突变体藻蓝蛋白和别藻蓝蛋白含量低；孢子囊枝的细胞较小，且大量形成时间比亲本晚15d；幼苗培养初期日平均生长量仅为(1.22±0.28)cm，当叶片长到60cm左右时生长优势逐步凸显，日平均生长量可达(7.50±1.18)cm；(2)翠绿色丝状体容易成熟，发育方式特殊，营养藻丝不经过藻丝加粗阶段，直接由球形细胞发育成孢子囊枝和壳孢子囊；翠绿色叶状体藻红蛋白含量低，仅有(5.5130±1.0496)mg/g；叶状体生长快速，60cm长的藻体日平均生长量高达(11.95±2.33)cm；(3)褐绿色突变体藻蓝蛋白、别藻蓝蛋白和藻红蛋白这3种色素蛋白和叶绿素的含量均较低；藻丝细胞短且细，叶状体生长速度较慢。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
