摘要

1. This paper gives a results of investigation on the propagating ways of this weed. 2. Number of seed setting plants in a paper-bag were 116, and sterilized plants were 128. But the self-fertilization of this plant must be studied by the classification of these types. 3. In low-land rice-fields, after harvest of rice crops, the average number of falling seeds of the were was 234.4 per 30cm squares of field surface and in the another case it was 117.2, but the percentage of germination was 14.51. We have obtained a few seedlings of the plant out of seeds from a block 20×21×20cm of area of low land field soil. 4. In chaffs which were 640.2g in the weight, we have found 568 of this weed seeds. In straws and seeds of rice some seeds of the weed were found. 5. We have not obtained the seeds which had veen brought into low-land rice-field with irrigating water. 6. This weed seeds have been buried in stable manure, the temperature of which was ranged from 58°C to 48°C, and they did not germinate in a month. But 10 seedlings of the plant have grown from immatured stable manure of about 200gr in the weight. 7. We have collected the seeds which have been passed through the digestive organ of hens, and 7 per cent of the germinated seeds. 8. The seeds were buried in soil for 6 to 15 months and some of them have maintained the activity.
