The spore germination and gametophyte development of 21 ferns are studied. It indicates that :① the development period of prothallium and young sporophyte of the same species is different due to seeding time of spores;② the optimal temperatures of spores germination and gametophyte development of 21 ferns are about 15 -24 ℃;③ the rate of spore germination of rare ferns is much lower than the ferns which occur large populations in nature;④ the treatment with GA 3 can accelerate the germination of the spores;⑤ the prothallium changes from large to small, green to yellow when young sporophyte comes out. The prothalliums of all 21 ferns die away after the appear of the 3rd leaf of sporophytes;⑥ shapes of the 1st and 2nd leaves of the young sporophyte are different from those emerged later;⑦ spores cultured in dark can not germinate;⑧ a prothallium can develop only one young sporophyte though it has many archegoniums, and the spore propagation with leaf mould substrate is an economical method.
摘 要:以腐叶土为培养基质,对 21 种蕨类植物进行了孢子萌发和原叶体发育的研究,结果表明:①不同时期播种的同种蕨类的孢子,发育出原叶体和幼孢子体所历经的时间长短不同;②孢子萌发和配子体生长发育的适宜温度约为 15 ~ 24 ℃;③稀有蕨类的孢子萌发率低,而在野外能形成较大种群的蕨类的孢子萌发率高;④用 GA 3 处理孢子可以促进萌发;⑤当原叶体上长出幼孢子体时,原叶体由大变小,由绿变黄, 21 种蕨类的原叶体都在幼孢子体上长出第 3 片叶时消失;⑥幼孢子体上长出的第 1 、 2 片叶在形态上与以后长出的叶不同;⑦孢子萌发需要光;⑧ 1 片原叶体尽管有多个颈卵器,但仅发育出 1 株幼孢子体;⑨利用腐叶土进行蕨类孢子繁殖是一种经济实用的繁殖方法。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.
结果表明:各物种的热值动态变化规律并不是统一的,这种变化可能与植物各器官热值的变化及生殖期出现的时间有关;各植物器官的热值普遍表现出穗的热值大于茎和叶;水生植物的热值明显小于中生性和湿中生性植物;种内热值变化随物候期变化有一定的规律,大约会出现2次低值、2次高值;种间热值差异是由于植物本身性质决定的,在相同生境和气候条件下,植物体中含能物质越多,就越易积聚热值,从而更适宜生长在此环境。
