中文摘要 | 本研究將Black Magic及Best Gold兩品種之彩色海芋種球,分別以GA3 100、150、200、250及300ppm浸泡基部15分鐘,結果顯示,GA3處理可提高海芋之單球萌芽數及開花數,卻會促進畸形花之發生與縮短花梗長度。海芋之開花數可隨著GA3之濃度增加而增加,其中Black Magic以GA3 250ppm處理,平均每株開5.9支花為最多;Best Gold則以200ppm處理,得4.1支花為最高。當海芋Black Magic品種以250ppm及Best Gold品種以200ppm之GA3處理種球時,整球浸藥此基部浸漬所得之開花數為多,而整球浸藥時,隨著浸藥時間的延長,雖然會增加抽花數,然而其花梗長度與寬度卻有減少之情形發生。 |
英文摘要 | The tubers of Zantedeschia cv. BlackMagic and Best Gold were dipped with Gibberellic acid (GA3) as a preplanting immersion at 0, 100, 150, 200, 250, or 300 ppm for 15 minutes. The results showed that GA3 treatments significantly increased the number of flowers and shoots. However, GA3 treatments significantly decreased the length of scape and increased the number of malformed flowers. The number of flowers per plant was increased as GA3 concentrations increased. The highest number of flowers per plant was obtained from the treatment of 250 ppm GA3 for cv. Black Magic and 200 ppm GA3 for cv. Best Gold. Dipping whole-rhizomes of Zantedeschia cv. Black Magic with GA3 at 250 ppm produced more flowers than dipping baserhizomes only. As the dipping time was prolonged, the number of flowers was also increased. But the length and width of peduncles was reduced. |
