Vegetative Propagation of Water Fir, Metasequoia glyptostroboides Hu et Cheng
Author: Yu Shing-Tuo
Journal of Integrative Plant Biology 1954 3(3)
    Water fir (Metasequoia glyptostroboides), now known the world over for its great scientific interest is also an economically valuable tree. Its timber is good, especially for construction uses. The tree grows very rapidly and straight. But on account of the limited number of seed-producing trees, propagation has been greatly restricted. The author began in 1953 to propagate by cuttings and obtained good results. Successcases were over 80 %. Cuttings 20-30 cm. long were made as soon as leaves were shed in the autumn and buried in sand pits to a depth of 15 cm. They were taken out in the middle of February and planted on their permanent sites. Cuttings so treated grow better than those made in the early spring and directly planted.

Studies on Porphyra I. Life History of Porphyra tenera Kjellm
Author: C. K. Tseng & T. J. Chang
Journal of Integrative Plant Biology 1954 3(3)
    1. Evidences are produced showing that carpospores of Porphyra tenera Kjellm. can give rise only to the filamentous Conchocelis-stage. Development of "normal" Porpohyra thalli in carpospore cultures is due to the presence of monospores mixed up in the same culture. 2. When water temperature reaches 15-17íŠ or higher, Conchocelis gives rise to swollen cells which, when mature, become asexual spores for which the name "conchospore" is proposed. Conchospores germinate in the same manner as monospores and are expected to give rise to the normal leafy stage of Porphyra. 3. Although there are as yet no experimental evidences, we believe, on the basis of our field observations, that conchospores will give rise to the dwarf type of the leafy Porphyra when water temperature rises above 20-22íŠ., and to the normal leafy type, when water temperature drops down to lower than 20íŠ. 4. Dwarf Porphyra are only a few millimeters to 1-2 centimeters in diameter. They multiply by monospores which are similar to, but much smaller than-those of the normal leafy Porphyra. It is believed that dwarf Porphyra are merely side issues in the life history of Porhyra. It is possible, that in places where summer water temperature is relatively low, say, lower than 17-20íŠ, the dwarf Porphyra stage may be entirely eliminated. 5. The important constituents of the life history of Porphyra are the leafy stage (the ordinary Porphyra thalli) giving rise, as a result of sexual reproduction, to carposporo, and the filamentous stage (the Conchocelis) giving rise to conchospores.

Electrophoretic Studies on Emulsion Prepared from Germinating Seeds with Special Reference to Soybean
Author: S. L. Chen, Y. L. Hsueh & C. H. Lou
Journal of Integrative Plant Biology 1954 3(3)
    Seed emulsions, owing to their high nutritive value, palatability and high digestibility, have long been important in Chinese dietary. The most outstanding example of its kind is of course "soybean milk" and its derived products, such as bean curd, curd sheet, curd skin, etc. Besides the soybean milk, "almond tea", "walnut cream", etc. prepared from various seed emulsions are also widely consumed throughout this country. In preparing a seed emulsion, the fibrous indigestible structure in the seed is removed, while most of the fats and proteins are retained, hi the case of soybean milk, for instance, over 80 % of proteins and 90 % of fats in the bean have been brought into the emulsion[3]. Tile fact that seed emulsion can be conveniently and economically prepared adds to its feasibility as a food for daily consumption.
