中文摘要 | 為保存並繁殖本省中海拔闊葉樹林中愛玉族群之優良單株,本試驗首 先以成年枝沾蘸生長素引朵丁酸(IBA)和奈乙酸(NAA)之不同稀釋濃度液處理後 ,扞插在間歇噴霧溫室中,觀察生長素促進發根效果,結果顯示愛玉成年枯沾蘸 IBA之發根效果較NAA處理者良好,其中插穗以IBA 1000mg/l 處理發根率60% ,效果最佳。未經生長素處理者發根率12%。為達到大量繁殖愛玉優良品系,本 試驗繼續以壓條法促使成年枝扞插成生活苗生長出具幼年性形態之枝條,此種幼 年枝生長迅速且莖節容易發生攀附根群,有利扞插成活。將幼年枝依有無帶根及 具不同葉數區分為四種插穗,直接扞插及移植於穴植管容器,內有2:2:1體積 量之混合蛭石、泥炭土與堆肥之栽培介質,再置於間歇噴霧溫室調查其成活率。 結果顯示帶根具一片葉枝插穗,有或無帶根而具4至6片葉枝插穗之成活率均達 92%以上,而無根具一片葉枝插穗成活率為28%。建議宜以前三種插穗材料大量 繁殖愛玉種苗。 |
英文摘要 | A study was conducted to promote rooting of the elite individual of Ficus awkeotsang Makino from the natural population by treating the shoot of mature stem with different concentrations of IBA and NAA, and growing in sand bed equipped with intermittent mist spray system. New shoots from the mature cuttings grew very fast and regain juvenility, therefore, large quantities of juvenile cuttings were obtained. The young cuttings were divided into four classes according to the leaf numbers and rooting conditions. The survival rate by direct transplanting and dipling propagation with intermittent mist spray was investigated and the results were as follows: 1.For the mature stem, the non-treated control has a rooting rate of 12%, and the IBA treatment increase the rooting rate up to 60% with the optimum concentration at 1,000 mg/l. 2.Among the four classes of juvenile cuttings, cuttings carrying roots with the shoot tip and one leaf, and cuttings with 4-6 leaves with or without roots all have a survival rate of 92% or better. Rootless cuttings with the shoot tip and one leaf has a survival rate of 28%. Therefore, for vegetative propagation, the first three cutting conditions should be used. |
