  germ tube
However, germ tube formation requires the availability of carbon and nitrogen sources.
      
These regulators in turn control the activities of presynthesized, and probably sequestered enzymes required for germ tube formation.
      
monogermtubi, derived from section Leuce, germinate only one germ tube, grow fast, produce dark-reddish conidiosorus clusters on the PDA medium, and are highly pathogenic to Populus tomentosa of section Leuce.
      
The germination process may be divided into two stages: I, spherical growth; II, emergence of a germ tube.
      
This new wall grows out, rupturing the spore wall, to become the germ tube wall.

  germination tube
The development of germinating Phycomyces spores was not inhibited by 5-fluorouracil (1 mM) until the emergence of the germination tube.
      
An electron-dense layer is formed on the inner surface of the inner germinal wall as the germination shield develops, and this forms the wall surrounding the germination shield as well as the germination tube.
      
In addition, deformations of the germination tube that were detrimental compared to normal development, were observed.
      
The spores germinated, and extended a germination tube, so cell growth was not affected.

The results now are represented in following four aspects. 1. The basidiospore was kidney in shape; Spores germinated in five ways; The first division of spore-nuclei might occur with in the germ tube. 2. The nuclei of hypha were mainly amitosis, but rarely mitosis; The nucleus of hypha generally was spherical or irregular in shape, eg. tadpole; The process of clamp connection was found in secondary mycelium. 3. From young basidia to one-nucleus basidia and to mature basidia, the size of basidia gradually became large; The nuclei of diploid were larger than those of ha- ploid. 4. The numbers of chromosome in nuclei of A. auricula was probably eight.

The materials were collected on Nov. 30, 1983 from rocks in the intertidal zone of the Yongning, Jinjiang county, Fujian Province. The mature plants were washed with sterilized sea water to remove attached diatoms and dirts. Individual mature cystocarps were selected and put under binocular microscope on each substratum in petri dish containing sea water. The experiment is carried out under room temperatures (9-18℃). Observation were made daily and the results were recorded or microphotographed.The shape of the mature carpospore is globular or subovate, with a diameter of 20-50 μm, each possessing a distinct stellate chromatophore. The carpospores were released onto the -substrata about 12 hours after culturing in room temperatures 14℃. The germination of carpospores began about 24 hours later. The spore wall slightly bulges out to form a tube, some germinating carpospores were seen to have two or three bulges. The bulged tube produced 昽ne, two or three primary filaments before developed into mature filaments, which are in three types: the uniparous, the biparous and the triparous.1. The mode of sporogenesis of Galaxaura oblongata belongs to immediate filamentous type, similar to Galaxaura fastigista discribed by Inoh, S. (1947). The result indicates that transparent and later deciduous cells, a morphesis among species of Galaxaura.2. The carpospores germinate by sending out one, two or three germ tubes which subsequently develop into three normal filaments, a biological feature of immediate filamentous type.3. In many cases the branches of filaments are terminated by long hair-like, nearly transparent and later deciduous cells, a morphological character of Galaxaura in germinating carpospores.4. The filament producing tetraspores in the life history of Galaxaura oblongata as described by Willian, H. M. may be refered to as the "Acrochaetium-like" phase.

于1983年11月在福建晋江永宁海区采集乳节藻Galaxaura oblongata(E11. et Sol.)Lamx.,用单个囊果离体采果孢子方法,于9—18℃条件下,在室内进行人工培养,观察其果孢子发生的形态,结果表明:乳节藻暴孢子发生类型为直接丝状型;依萌发管的数目,把果孢子发育成为分枝丝状体阶段的形态分为单出型、双出型和三出型三种,此系直接丝状型的生物学特征;在细胞的末端出现长的、无色透明的毛状的细胞,是乳节藻属的果孢子在发育过程中所特有的形态特征。
