中文摘要 | 為建立金柑無病毒健康種苗之繁殖體系,蒐集適合健康芽接用酸桔砧木種子,經高溫熱水處理,打破休眠,播種後成活株供砧木嫁接用,每公頃可節省砧木種苗費用43,000元。加強無病毒金柑芽體切接繁殖,利用編號HF-1健康原種品系分離培育出HF-1~1至20號等12種芽系。以無毒化接穗芽體進行嫁接,成活率84.1%,山坡地試區株高顯著性地(p=0.05)高於平地試區,單株結果量以平地試區編號HF-1~9號芽系22公斤與對照組比較具顯著差異(p=0.05),平地各芽糸產量均高於山坡地試區品系,果重以山坡地試區之編號HF-1~16及平地栽培區HF-1~15號分別為20.2及20.1公克,顯著性地(p=0.05)高於兩處其他品系,平地試區供試芽系果粒大於山坡地試區,果實糖度平地栽培與山坡地試區無顯著差異(p=0.05),兩處供試芽系果實酸度仍偏高。平地或山坡地健康苗試作區,植株園藝特性表現均顯著性地(p=0.05)優於對照品種。 |
英文摘要 | In order to establish propagation systems for certified virus-free seedlings of Kumquat, seeds of healthy Sunki (C. sunki) rootstock suitable for future grafting were collected. These seeds were treated with hot water and their dormancy were broken; and then grown into rootstock seedlings for grafting. By doing so, NT$43,000 of rootstock cost was saved for each hector. To obtain virus-free Kumquat budwoods, the virus-free line HF-1 was further separated into 12 sublines with names of HF-1-1 to HF-1-20 individually. Virus-free budwoods were grafted onto Sunki rootstocks with a survival rate of 84.1%. The grafted seedlings were planted in a sloped-land (SL) and a level-land (LL) testing orchard. SL orchard had higher average plant height than LL orchard. The HF-1-9 grown in LL had the highest yield per tree of 22.0 kilograms, which is significant higher (p=0.05) than that of control. All seedling lines grown at the LL had higher yield than the SL. The HF-1-16 at SL and the HF-1-15 at LL had the greatest average fruit weight of 20.2 and 20.1 grams respectively; that were higher that all other lines at each orchard. The LL orchard had larger average fruit size than the SL orchard. There were no differences (p=0.05) in soluble solids contents between the two orchards. Pretty high levels of acid content were found in fruits form both orchards. Overall results indicated that the horticultural performances of the virus-free Kumquat trees grown in either SL or LL orchard were significantly better than that of the control. |
