In addition, the effect of each weight of bulbs on germination was studied. The results obtained are summarized as follows : 1. Approximately 72% of the bulbs under observation occurred within the upper 10cm of the soil with the percentage as low as about 2 to 3 at depths 20cm or deeper. 2. There were more daughter bulbs in Maage than in Jaagaru with a high percentage in both soils at depths 25cm or deeper. 3. As to the days prior to germination, leaf numbers and daughter bulb numbers, there was a strong correlation between these three characters and varying depth. These same three characters were also correlated strongly among themselves, the correlation of the leaf numbers with the daughter bulb numbers being especially prominent, as given by the form r=0.987. 4. Highest values on the germination percentage, fresh weight and daughter bulb numbers were obtained at the 5cm saturation level with the degrees of growth progressively lower toward higher levels. No trace of germination was observed under the full saturation level conditions. 5. Bulbs in their early growth stages fell in the range from 0.1 to 2.5g. A relationship in the mode of logarithmic normal distribution was evident after the peak 0.3g. 6. The germination percentage in bulbs varying from 0.3 to 2.0g ranged between 60 and 80 at the end of a 4-day period following the placement of the bulbs on the cotton-filter paper Shares, a considerably high performance for any such short period. In contrast, the diurnal germination percentage recorded for the weight classes below 0.2g and above 2.0g was significantly low.", "subitem_description_type": "Other"}, {"subitem_description": "紀要論文", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学農学部"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/4261"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "琉球大学農学部学術報告"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
