中文摘要 | 本試驗係以天然生土肉桂14單株及7年生之31個營養系為帶葉枝插的材料,以生長激素NAA,IBA及NAA加IBA不同濃度(0至10,000 ppm)粉劑處理,扦插於溫室定時噴水設備下之砂床及填裝泥炭土、珍珠石、蛭石 2:1:1與泥炭土、珍珠石、蛭石、牛糞堆肥6:3:3:2之比例的穴植管內。扦插的結果顯示:各種生長激素及其濃度與不同扦插介質間對土肉桂插穗之發根率,平均發根總長及平均發根數均無顯著之效應,但不同單株及營養系間均呈極顯著之差異,有些單株及營養系在扦插50天後其發根各達67% 及90%,而有些仍維持0%。顯示欲大量繁植土肉桂優良化學品系只有從選擇易發根之營養系為主。而土肉桂插穗可直接扦插於裝填泥炭土、蛭石、珍珠石混合介質之穴植管內且根系生長良好,此種穴植管直接扦插法不僅可省下移植的步驟,且可降低以後苗木之包裝、運輸及出栽的成本,極有助於土肉桂優良化學品系之推廣栽植。 |
英文摘要 | The leafy stem cutting material from 45 clones of Cinnamomum osmophloeum were treated with 0, 500, 1,000, 3,000 and 10,000 ppm of NAA, IBA and NAA+IBA powders, and tested for rooting ability under intermittent spray in greenhouse. The rooting media were sand, the mixtures of peat, vermiculite and perlite (2:1:1) and the mixture of peat, vermiculite, peat and compost (6:3:3:2). The results showed that the difference of percentage rooitng, mean root length and mean root number were not significant among growth regulators, concentrations of growth regulators and media, but highly significant among individuals and clones. Some clones had 67% to 90% of rooting after 50 days, nevertheless, some others still remained no rooting at all. It suggests that the one of the best ways of in large quantity of C. osmophloem is to use easy-to-root clones of this species. The cuttings directly inserted into dibbling tubes filled with medium of the mixtures of peat, vermicultie and perlite may be recommanded for its economical potentials. |
