JOURNAL FREE ACCESSIn this report, a method of identification of species by means of the color reactions in the water extracts of the bark is suggested. The bark of the root was sliced off with a sharp knife. The exposed surface of the root changed into yellowish color very quickly and intensively with Lotus, moderately with virginiana and the least with kaki. The sliced bark was weighed and immersed in separate beakers containing a volume of distilled water of fifteen times as much as the weight of the bark to provide water extracts. After two to twelve hours'extraction, the color of the solution in the test tube was deep yellowish brown in D. Kaki, yellow orchre in D. Lotus and pale yellow in D. virginiana (“A”in the Plate). The hydrogen ion concentration of the extracts was 5.39, 5.91 and 5.65 respectively. No apparent change in color occurred in addition of any acid.An addition of a small amount of alkaline solution, however, gave a sudden change to the color of the original extracts, showing a purple garnet color in kaki, reddish violet in Lotus and pink in virginiana (“C”in the Plate). This fact seems to suggest that there exists certain coloring matter in the root of these Diospyros species, which is yellowish in acidic and reddish in alkaline solution. In addition of zinc chloride or copper acetate solution there were also observed different color reactions accompanied with characteristic precipitates (“D”, “E”, “F”and“G”in the Plate). Sections treated with alkaline solutions revealed that the coloring material distributed intensively in cork layer and very lightly in phloem and xylem tissues of kaki root. In Lotus and virginiana roots, the coloring material seems to exist in fair amount in xylem and phloem portions and in relatively small amount in periderm.View full abstractDownload PDF (1839K) -

JOURNAL FREE ACCESSIn this paper the author reports that the germination percentage, vigor and time for the tube rupture are greatly different according to the kind of sugar used in nutritive solution for germinating bed. Monosaccharides are inferior than disaccharides. Trisaccharides and tetrasaccharides are inferior than both monosaccharides and disacchardes. Among disaccharides cane sugar is the best. Milk sugar is as valuable as monosaccharides though maltose is not more nutritive than monosacchorides. In dilute solutions the tube rupture comes very early and the last length of the pollen tubes were longest in cane sugar solution, shortest in tri- and tetrasaccharides solutions.View full abstractDownload PDF (683K) -

JOURNAL FREE ACCESS1) Boron influence favourably the germinability of pollen grains of grape vine Muscat of Alexandria in a marked degree and 2) it probably acts as a special nutrition for generative growth upon the setting of berries of the variety, because of the augmentation of the number and percentage of normal berries.View full abstractDownload PDF (241K) -

JOURNAL FREE ACCESSThe present paper deals with the inheritance of the round and the long shapes of fruits in the eggplant. Four varieties were used; Aonasu and Oserikawa, as round parent, Buko-haku and Hakata-naga, as long parent. Shape index was determined by dividing length by width.
The F1 was approximately intermediate in shape, but nearer to the round parent. Consequently, the round shape is incomplete dominant over the long. The F2 distribution showed nearly a skew curve. It seems probable that the difference in shape of fruits in the two parental races is due to at least three or more partially dominant factors, each of which differs in their effects. Just how these factors operate can not be well determined at present.View full abstractDownload PDF (253K)
