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。

Flavone and pyrocatechol were chosento act as model compounds of different structure aspects of flavonoids and theirreactions with α-hydroxyl ethyl peroxyl radical were studied. The rate constants of thereactions of α-hydroxyl ethyl peroxyl radical with flavone and pyrocatechol weredetermined to be 〓 and 〓,respectively.

Comparing the nucleotide sequences of 16S rRNA gene and ribosomal protein gene, we could find that these two strains have the highest homology of 99.4% and 99.8%, respectively. The nucleotide sequences of 16S rRNA gene for the CWB-YN strain shared higher homology (98.5%,98.9% and 98.0%) with phytoplasma strains in Tomato big bug 16SrI-A group, Western aster yellow (16SrI-B group and Clover phyllody (16SrI-C group). But it is obviously under 97.0% with other phytoplasma groups. The CWB-GZh strain shared higher homology (98.7%,99.1% and 98.3%) with phytoplasma strains in Tomato big bug(16SrI-A group ),Western aster yellow (16SrI-B group) and Clover phyllody (16SrI-C group).

The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.
