英文摘要 | Taiwan Monopoly Bureau provides tobacco seeds amounted 500 kg every year to tobacco farmers without charge. All of the seeds are produced by the Tobacco Research Institude. This mass production of tobacco seeds, associated with high temperature and humidity during storage has caused the tobacco seeds to be occasionally damaged, because of higher initial moisture content. The present study is to find out the moisture content that is safe for seed storage under Taiwan's condition. The moisture content of tobacco seeds is determined by subject the seeds to various length of period for air drying. Five different lots of seeds with different moisture content were obtained in 1955, they are 8.517, 8.721, 9.146, 10.318, 10.422%, and then put them into air tight container for storage respectively. All of the seed lots were to be sampled for germination test after 3.5, 5, and 8 months storage. The results show that there is profound effect for moisture content on germination percentage of tobacco seeds, the higher the moisture contains, the lower the germination percentage is, and the decrease of germination percentage as the length of storage prolonged, is highly related to the moisture content. The seed lots of moisture content more than 10%, their germination percentages were greatly reduced even after 3.5 months storage, the highest lot with 10.422% moisture completely lost its germinating ability after 8 months storage. Since the lowest moisture content of the seed lots in the present seudy is about 8.5%, so we can not draw a definite conclusion on the most safe moisture content for storage. However, according to the result, we can say that the moisture content at least to be around 8% would be safer for tabacco seed storage under Taiwan's condition. |
