中文摘要

2012年2月至2013年1月每月定期採集芳樟醇型(linalool type)土肉桂(Cinnamomum osmophloeum Kaneh.)之接穗嫁接於陰香(Cinnamomum burmannii Bl.)砧木,接穗來源分別取自20 年生(營養系分株之母株original ramet1,簡稱R1)與5年生營養系造林木(來自前營養系母株扦插苗 ramet2,簡稱R2),與實生苗造林之7年生林木(R1後裔苗saplings,簡稱Sp)。嫁接成活高峰出現在4 月,為52.0±11.0%,而其他月份嫁接成活從2012年2月至2013年1月分別為2.0±4.5%、18.0±8.4%、 0%、2.0±4.5%、2.0±4.5%、2.0±4.5%、4.0±8.9%、2.0±4.5%、4.0±5.5%、0%、8.0±8.4%。嫁接成 活率偏低,可能是植物物候因素及生理狀態所致。2月嫁接砧木死亡率高達46%,最低0%出現在 10月。接穗生理年齡與嫁接成活率並無顯著關係,R1、R2及Sp林木所採穗條之嫁接成活率分別為 8.0±13.0%、14.0±11.4%及8.0±11.0%。取自3種來源林木插穗之扦插試驗結果,顯示植物生長調節 劑處理對發根並無顯著效果,無藥劑處理、IBA處理及NAA處理的平均發根成活率分別為38.3%、 40.1%及35.6%。扦插穗條生理年齡影響成活率最大,Sp所採穗條之發根成活率最高,平均為 84.0%,顯著高於R1及R2平均發根成活率21.0%及8.5%。

英文摘要

Different sources of scions collected from Cinnamoumum osmophloeum ‘linalool type’ Kaneh. were grafted onto C. burmannii Bl. seedling stocks from February 2012 to January 2013. Scions were collected from 3 sources that were 20-years-old trees (ramets, rooted cuttings from wild trees, denoted by R1), 5-years-old trees (ramets, rooted cuttings from R1, denoted by R2), and 7-years-old trees (offspring seedlings derived from R1, denoted by Sp), respectively. Plants of both R1 and R2 were planted in Lienhuachie, Nanto County, while Sp were planted in Wulai, New Taipei City. The greatest survival rate of grafts occurred in April and was 52.0±11.0%. The survival rates for the other months from 4.0±8.9%、2.0±4.5%、4.0±5.5%、0%、8.0±8.4%, respectively. The low survival rate may due to phenology and physiology status of the scions. The greatest mortality rate of stocks was 46% in February. The lowest mortality rate of stocks occurred in October and was 0%. There was no significant difference between physiological ages of scions. Survival rates of grafts for R1, R2, and Sp were 8.0±13.0%, 14.0±11.4%, and 8.0±11.0%, respectively. Rooting rates of cuttings treated with control, IBA, and NAA were 38.3%, 40.1% and 35.6%, respectively. They did not differ significantly among the treatments for the 3 sources, indicating that plant growth regulators did not enhance root formation of cuttings. Physiological ages of cuttings affected rooting ability. Rooting rate of Sp cuttings was 84%, significant greater than that of R1 and R2, which were 21.0% and 8.5%, respectively.
