| [[abstract]]桶柑嫁接於7種砧木定植於苗栗獅潭，調查砧木種類對植株生長、產量與果實品質的影響。定植後4至5年間有40.0%酸橙砧與5.6%柚砧植株因衰弱而淘汰，第7年檢定萎縮病 (tristeza)，結果顯示以酸橙或柚作為砧木的植株為感病，但柚砧者較耐病，其他5 種類包括酸橘、美女橘、粗皮檸檬、Troyer 枳橙及Swingle 枳柚作為桶柑砧木，無論感染與否，外觀均無顯著差異，應屬於耐病或抗病。定植後第5至第10年之產量，Troyer 枳橙砧者最高，其次為美女橘與粗皮檸檬，Swingle枳柚與酸橙又次之，酸橘及柚最低。比較第8 至第10 年間之果實品質，處理間主要差異為，粗皮檸檬砧之果汁率、可溶性固形物含量及含酸量均最低，3年中分別有2年達顯著差異。品質特性之主要項目在其他6種砧木間之差異較小，其高低在各年之間也不一致。 Tankan tangors grafted on seven rootstocks were planted in an orchard located in Miaoli County. The effects of rootstocks on tree growth, yield and fruit quality were investigated. 40% of the trees grafted on sour orange and 5.6% of trees on pummelo declined during the fourth and fifth year after planting. Plants were indexed for tristeza by RT-PCR in the seventh year. The results showed... |

| [[abstract]]In order to evaluated the effects of different species of rootstocks on fruit production of ‘Murcott’ tangor. Scions of ‘Murcott’ tangor were grafted on one year old seedlings of eight species of rootstocks and planted in the Chia-Yi Agricultural Experiment Station and two sites at Gu-Keng, Yunlin County. Tree growth, yield and fruit quality were investigated at the sixth and seventh year after transplanting. Accumulated yields of healthy plants were high on rough lemon and ‘Rangpur’ lime, intermediate on trifoliate, ‘Swingle’ citrumelo and ‘Troyer’ citrange, low on sour orange and Sunki. The fruit qualities were similar among most combination of the ‘Murcott’ tangor and rootstocks species. Total soluble solids and acid contents were high from... |

| [[abstract]]為了解多胚柑桔之珠心胚與有性胚發育的情況，以提高雜交育種的效率，以雪柑為母本，分別與枳殼、晚侖夏橙 (Valencia) 鳳梨橙(Pineapple) 雜交。於授粉後80、100、120及140天採收果實，於解剖顯微鏡下調查胚數;以枳殼授粉者並播種於MS培養墓，以探討有性胚苗的獲得率。結果顯示，在調查的過程申，所增加的胚數甚少，尤其是晚侖夏橙與枳殼授粉者，且Stage I 之小胚在授粉後第80至第100天明顯減少，顯示大部份的胚應同時發育，早期胚培養以取得有性胚的方法，在本試驗之什交組合中並不適用。以枳殼授粉者，什交苗的獲得率，隨種子之成熟而增加，因此以胚培養提高什交苗之獲得機會，應以種子即將成熟時較為容易。 'Shueh-ken' orange (C. sinensis Osbeck.) was pollinated with 'Valencia', 'Pineapple' and trifoliate oranges. Fruits were harvested 80, 100, 120 and 140 days after pollination, numbers of embryos were counted with dissecting microscope, and the embryos of hybrid seeds crossed by trifoliate orange were cultured on MS medium supplemented with 7.5g/l agar and 20g/l sucrose. Average number of embryos increased slightly throughout the growing... |
