摘要: 
本研究係以台灣主要切花用玫瑰花品種為材料,利用單節扦插方式,配合
自動噴霧插床設施,探討影響單節插穗發根和腋芽生長的因子,期能提高
單節扦插之生產效率,以建立單節扦插苗之商業生產體系,大量快速繁殖
種苗,解決現階段國內需苗殷切之問題。植物生長素 Auxin具促進發根效
果,插穗經粉劑處理者,扦插苗發育較好,以 NAA 2000mg/kg 效果最佳
。單節插穗帶有4片或5片小葉,其發根率與腋芽萌芽率最佳,而不帶任何
葉片者,雖偶有少數根則插穗無法成活。插穗原著生位置愈低,其腋芽萌
發愈困難。以 BA 及 GA3 處理,皆可促進腋芽之萌發,尤以含 BA 1.0%
、GA3 0.01% 羊毛脂膏效果最為顯著。單節插穗之發根與萌芽在品種間有
很大的差異; ''Papa Meilland'' 與 ''Samantha'' 生育最好, ''Blue
Moon'' 和 ''Super Disco'' 單節插穗生育最差;而且其葉片光合率與插穗中
所含之營養元素較低;而不同季節之育苗成活率,7月及10月育苗優於1月
及4月份育苗者,其發根所需日數,前者可以在三週以內形成,而後者則
需超過5週。單節扦插育苗之粗成本為3987元/1000株,而傳統之之高壓苗
則為 4524元/1000株。單節插穗之根原體形成過程,以石臘切片觀察。扦
插後第7天,插穗下方切口的形成層,即形成癒傷組織,且發現根原體形
成於次級韌皮部之組織中。第10天時,發現射髓組織頂部之細胞有些平週
分裂(actilinal)組織。第13天時薄壁細胞有新的薄壁細胞分裂。第18天
時韌皮部薄壁細胞發現新的根原體,第22天時可見根原體穿透皮層(
cortex)組織往外伸長。

Factors of single-node cuttings of rose cultivars for cut
flower under mist were studied, in order to enchance the
efficiency of propagation and to establish aproduction of rose
plantlets for cut flower business. The highest rates ofrooting
and axillary bud sprouting were found on the single-node
cuttings with a 4 or 5-leaflet leaf .Single-nodecuttings failed
to root without leaflet.After rooting itwas more difficult for
axillary bud sprouting. Whe n the cut-tings from the lower
position on mother plant.The sproutingof axillary bud was
improved when plantlets treated withbenzyladenine or
gibberellin acid loalin paste at 1.0% or 0.01%,respectively.
Therewere difference on root and shoot growth among cultivars.
The development of ''PaPa Meilland''and ''Samantha'' plantlets were
the best, when ''Blue Moon''and ''Super Disco'' were the poorest.
The net photosynthesis and the inorganic constituents of the ''
Blue Moon'' and ''Super Disco'' were also poorer. The quality of
plantlets propagated in July and October was better than that
in April and January. In addition , in the former reasons;
cuttings rooted by 3 weeks when in the later seasons cuttings
rooted over 5 weeks. By calculating roughly,the cost of
producting 1000 plantlets was 3987 N.T.dollars by single-node
cutting or 4524 N.T. dollars by air layering.The developmental
stageof rooting in single-node cutting of ''Samantha'' rose was
observed. After 7 days,cullus formed from the cambium on the of
cutting. After 10 days, top of thephloem ray parenchyma found
some actilinal parenchyma tissue. After 13days, some new
parenchyma were found in pholem tissue. After 18 days,root
primordia was found in phloem parenchyma, and after 22 days.
Young root primordia elongated through the cortex.
