    Gastrodin is a phenol-glucoside, obtained from Gastrodia elata Blume (Fam.Orchidaceae) by Investigator Zhou Jun and other of The Institute of Botany of Kun-ming, Academia Sinica. The structural formula of gastrodin is p-hydroxymethy phenyl -β-D-glucopyranoside, its chemical formula is C13H18O7, forming a white pin cry-stals, with a melting point of 154-156℃. It is synthetized now.In a previous paper, the authors reported the sedative and anticonvuisant effects of synthetic gastrodin and its genin. The prescnt paper reports the subacute toxicity and the effects of gastrodin and its genin on the heart and small intestine as followg.

    The dried roots of Heracleum nepalense D.Don. were extracted with ether, and the extract chromatographed over alumina, afforded four furano-coumarins which were identified as pimpinellin, bergapten, sphodin and isopim-pinellin by mp.IR and NMR spectra. In addition, 6-sitosterol was also separated.

    The mycoflora of Yunnan and Tibet of China was extroardinarily rich in nature. The most part of this plateau was well covered with plant vegetation,those fungal species were numerolls, the myco-resources were abundant, and the elements of mycoflora were full of complexity.By analyzing the materials available in the present investigation, the author is able to classifies the phytogeographic division of Yunnan and Tibetan higher fungal flora into the following 13 regions.

    The habitat of mountains is the wettest dtle to the cloud belt and orog- rapllic rain. The vegetations of vertical zone all possess wet charactcr. The main vergetation of tropical mountains is the mountain rain forest; and the vertical zone of subtropica1 mountains is characterized by the humid evergreen broad-leaf forest.In the subtropical region, the enviroments of incised valley are very dry and hot because of the influences of a strong local up-valley air current and the foehn. The main vegetation at the bottom of the dry valley is the type of Savannah and succulent thornbush, which should be a product of the local enviroment or an azonal vegetation.

    The present article studies the aquatic vegetation of the following lakes of Yunnan plateau: Dian Chi, Erhai, Zhibi Hu, Jian Hu, Xingyun Hu, Fuxian Hu, Julu Hu, Yru Hu, Yanzhong Hai, Lugu Hu, Chen Hai, Chan Hu.Ecological analysis shows that distribution of the aquatic plant commnunities in lake is close relative to the physical and chemical environments, perticularly, to the depth and transparcncy of lake water. At the Yunnan plateau, the more depth of lake water is, the more transparency the water reaches and in the more water deep the aquatic plants can grow. For example, the maximum water depth of the Lake Fuxian Hu is 164 m, maximum transparency in this lake reaches 8.5 m, and the plants can grow in the water of 20 m deep; in the Lake Yru Hu maximum depth of water is 5 m, maximum transparency is 1.8 m, the plants can grow in the water about 3 m deep.

    Sect. Mucroniferae Fedde is an endemic alpine group of the Genus Corydalis Vent.in Qinghai-Xizang plateau and Himalayas. The center of the distribution of this Section is between 28-32℃ N. 88-96°E. All species of this section, except C.brevirostrata C.Y.Wu et T.Y.Shu distributing merely up to 3600 m. altitude in the forest meadows, dwell in the plateau-desert, alpine scree, gravel or river banks up to 4000-5400 m. altitude. They had in common developed the specific characters adapting dryness and coolness under the natural condition of high altitude and low latitude. They are the cushion-like alpine herbs which possess taproot, leaves with flattened petio1e, 1-3 pinnatisect. The ultimate lobules of leaves elliptic or spathulate are often mucronated.

    On the basis of the morphology of p1ant and geographic distribution, and the content of aristolane type cornpounds and the transformation relatiofl in the essential oil, we consider that N. grandiflora is a primary specics, while N.chinensis and N. jatanlansi have cvolved from this species. Nardostachnol acetate (Ⅵ) has a strong but perssisting woody odor character. Nardostachonc (Ⅲ) has a characteristic sandalwood odor and blends well with rose and muguet fragrances. These two substances are especially suitable for compounding perfumes of rose, rose-sandal and fougere types, and have a very good fixative property; they may be regarded as valuable perfumery materials.

    Treating the cultured anthers in early stage with mutagens ethyl methane sulphonate(EMS), 1-methyl-3-nitro-1-nitrosoguanidine (MNNG) and ethylene imide (EI), we observed an enhance in the formation of albino pollen plantlets with an decrease in the formation of green plantlets, and thus an obvious increase of the percentage of albinos in total plantlets, for instance, 34.9% in treatment of 2.5 ml/1 for 8 h. (26℃) on cultured anthers of variety 8126,compared with 6.7% of control. But even in this case, mutations in other characters was observed only in very few pollen plants. Albino seedlings also occurred in progenes of a few pollen plants, the frequency of its occurence in H2 strains was 100 times more than that in H3. The experimental results are available to the claim that the cause of albinos formation might be the losses of somc genes. The formation of more albino pollen plantlcts callqed by mutagens would give much difficulty to the attempt of producing mutants through in-ductive mutation on cultured pollens of rice.

    The cxperiment was carried out to study the effects of various light qualities on morpllological and physiological changes of rice seedling.Seeds of the rice variety "ZHI XUAN NO.0090"(Oryza sativa L.bubsp Keng)were sown in the fertile soil with nealy optimum supply of water in the early growing stage.The seedlings were grown for 12 days under 10 hours continuous illumination of Red(R),Blue(B),Yellow(Y),and Colorless(L)light at the average temperature of 25—28℃.
