protonemata

基本解釋

Protonema (pl. protonemata) The young bryophyte gametophyte that develops following spore germination.
原絲體：苔蘚植物中直接由孢子萌發(fā)形成的結(jié)構(gòu)稱(chēng)為原絲體。
The mature gametophyte plants develop from buds that form at several points along the protonema.
原絲體上形成1個(gè)或幾個(gè)芽體，芽體進(jìn)一步發(fā)育為配子體。
Protonema The green, filamentous growth that arises from spore germination in liverworts and mosses and eventually gives rise to a mature gametophyte.
由葉苔或苔蘚的孢子萌芽發(fā)展而成的綠色絲狀生長(zhǎng)物,最終發(fā)展成配子體。
Describing the characters and developmental features of spore germination and protonema development of moss applied in this research by microscopy.
采用顯微觀察的方法具體描述了蘚類(lèi)植物孢子萌發(fā)與原絲體發(fā)育的特征及發(fā)育特點(diǎn)。
The process from the spore germination and protonema growth to development of the gametophyte are illustrated and taken microphotographs.
