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。

We didn\'t find activated points in cerebellum and deeper brain.3.Acupuncture of sham point can significantly activated BA2,6,8,13,21,37,40,44,45,47,putamen and other areas.Both the left and right side of the brain have activated points,but points on the right side are more than those on the left.Both sides of middle temporal gyms,parietal lobule,supramarginal gyms and the lentiform nucleus have obvious activated points.The activated points mainly concentrated in the cerebral cortex,the deep-activated are mainly in the putamen.4. Sham needling in sham point can significantly activate BA6, 8,9,10,18,21,37,40,43,44.The activated points are mainly distributed in the right side of the brain.The left side also has some activated points;5.In the comparasion of Acupunture and sham-needling in S J5,we find that BA8 and cerebellum have distinct regional activated points;6.In the comparasion of acupuncture in SJ5 and sham point,we find BA2 and left cerebellar regions have activated points;7.Sham needling in S J5 compared with sham point,we find BA7,8,9,18 and other areas have activated points,the main activated points are at the left brain.It is not difficult to find that the distribution of activated points are mainly in the middle brain,no obvious activated points at the temporal lobe.

As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

For CAT, only 3 bands were detected in all tissues, CAT-1 appeared in the leaves of three buckwheat and clearer in F. cymosum and F. cymosum 1. CAT-2 was detected in different location in leaves and caudexes. CAT-3 existed in the leaves though it was unclear.
