It took a minimum of 13 months after a spore sowing for a sporophyte to be produced by a gametophyte. Increasing the wild population will likely be slow and difficult.
由於孢子体的生成至少需13个月,以及其低生成率,可能导致其野外族群之扩增极为缓慢且困难。

On the basis of results of our test,we suggest that low temperature pretreatment changes content of endogenous IAA and iPA of anther,thus interrupts previous developmental direction of pollen and induces microspores develop from a gametophytic way to a sporophytic way.
根据实验结果,推测低温预处理改变了花药内源IAA和iPA含量,阻断了花粉原来的发育方向,使其由配子体的发育途径转向孢子体的发育途径。

In filicophytes, there was a relatively high ratio of VA mycotrophy in the eusporangiates, and there was no autotrophic in the eusporangiates; but the ratio of autotrophic was up to 71%, and the ratioes of VA mycotrophic and facultative mycotrophic were low, 15% and 14% respectively in the leptosporangiates.
用碱解离、酸性品红染色法对云南热带、亚热带自然生长和部分移栽到温室中的256种(拟蕨类植物20种,真蕨类植物236种)蕨类植物孢子体的VA菌根状况进行了调查研究,结果发现,在拟蕨类植物中,孢子体只存在兼性VA菌根营养和自养两种菌根营养类型,两种类型,两种类型所占的比例相当;在真蕨类植物中,厚囊蕨类植物VA菌根营养的比例较高(92%),且无自养类型;而在薄囊蕨类植物中,自养型占71%,VA菌根营养和兼性菌根营养所占的比例都不高,分别是15%和14%。

Japonica and 1.3 cm of U.pinnatifida which showed heterosis in growth during the temporarily sea cultivaton. The phenotypic character of F_1 juvenile sporophyte of L.japonica♀×U.pinnatifida♂was similar to that of the female parent, namely, L.japonica which generated no rudiments of the pinnate lobations.
海带♀×裙带菜♂杂交组合的受精率为20-33%,在暂养期间F_1幼孢子体达到2.2 cm,大于海带、裙带菜幼孢子体的1.8 cm和1.1 cm,表现出生长优势;F_1幼孢子体表现出母本海带的性状,无裂叶缺刻雏形的形成。
