中文摘要 | 本研究之目的旨在探討不同夜間照光時數對印度棗開花、著果、及產期之影響, 以期能得知最適照光時數,作為栽培之應用。以4年生特龍品種印度棗(Zizyphus mauritiana Lam. cv. Telong)為材料,處理為不照光(對照)、夜間照光12小時、9小時、6小時、3小時 等5種,處理時間為40天。結果得知,照光時數愈長,有開花愈早、早期開花數愈多、著 果愈多之趨勢。提高早期開花數及著果數之效果以照光12小時、9小時、6小時之處理較佳。 產量方面,夜間照光12、9、6小時處理比3小時處理和對照組高。產期方面,照光12小時 者可提早45日,照光9小時及6小時可提早40及35日,且果實品質與同時期不照光處理 者沒有差異。故夜間施予照光對印度棗產期提早之效果似屬可行,若考慮電費及蔬果人工成 本,則以每日延長照光6至9小時較經濟。 |
英文摘要 | To understand the flowering and yielding responses of Indian jujube under light treatment during the night, four-year-old Telong Indian jujube (Zizphus mauritiana Lam. cv. Telong) were used as materials, and five kinds of lighting hours including 12, 9, 6, 3, and control (no lighting) for 40 days were treated. Results showed that the tendency of the longer the lighting hours during the night, the earlier the flowering, the more flowers per node, and the earlier and more fruit sets per node were found. The better effects in advancing flowering and fruit setting were found for treatments of 12, 9, and 6 hours of lighting. More yields were found for light treatments of 12, 9 and 6 hours than that of 3 hours and the control. A total of 45, 40, and 35 days of yielding dates could be advanced when light treatment of 12, 9 and 6 hours was applied during the night, respectively. At same harvesting date, no significant difference in fruit quality such as fruit size, total soluble solids between light- treated and non-treated plants was also found. It seems that night lighting treatment was useful and practical in advancing the yielding dates in Indian jujube. Considering the electricity and fruit thinning labor costs, the betteer light treatments of 6 and 9 hours during the night were found economically. |
