Keywords: | 抽苔;帶化率;苗體直徑;單株種子收量;發芽勢;bolting;percentage of fasciation;diameter of plant;seed yield per plant;velocity of germination | Issue Date: | Dec-1966 | Publisher: | 臺灣園藝學會 | Journal Volume: | 12 | Journal Issue: | 3-4 | Start page/Pages: | 28-31 | Source: | 中國園藝 | Abstract: | 1.本試驗自民國五十三年一月一日開始至五十四年六月底止結東,自五十三年一月一日至十二月一日每月初播種一次,共分十二次播種,試驗地點在海拔2250公尺,年平均溫度12.5。C之福壽山農場進行。 2.在年平均溫度12.5。C之福壽山農塲,十月一日至十二月一日,一月一日至三月一日播種者,苗體發育不大,平均直徑最小2.6分,最大6.76公分,至抽苔季節,花序正常,分枝整齊,結籽良好。 3.自四月一日至九月一日播種者,苗體直徑平均在7.5公分以上,雖能抽苔,花序呰成畸形,畸形花序之頂端,略現花朶,均花而不實,無種孒可收。 4.花序正常之植株,單株種孒收量,以早播者較晚播者為多,種子形粒大小,亦以早播者較晚播者大。 5.在年平均溫18。C以上之地區,歷年試驗,不論大苗,小苗,均難抽苔開花。 1. In this experiment the author studied the relation between the Plant sue and occurrence of fasciated flower sta1k in connection With the seed production of Jpanese ever-season radish. 2. As the seed production of Japanese ever-season radish was impossible in the area Where the annual mean temperature exceeds 18。C, the experiment was carried out at the Fu Show-Shan Farm ( 2,250 meter altitude, annual mean temperature 12.5。 C ), Taichung prefecture during the period of January 1964 to June 1965. The radish seeds were sown on the first day of each month in 1964. The plants which were sown in January, February, and March bolted and flowered in the same year, others bolted and flowered in the next year. 3. It is note worthy that the occurrence of fasciated flower stalk were closely related with plant size, other words, the plants which were sown from April to September had large plant size at flowering season, and all of these plants bolted fasciated flower stalks. No seed was obtained from these plants. On the other hand the plants which were sown in January' February' March, October November, and December bolted flowered, and produced seeds normally in spite Of they were small in plant Size. The author also observed that early seeding resulted in higher production of seeds. |
