Effect of Bagging on Fruit Growth and Quality of 'Wentan' Pummelo (Citrus grandis (L.) Osbeck) and the Temperature Inside the Bag
No full text爲探討不同時期套袋對文旦果實生長與品質的影響，五月下旬起，每一個月套袋一次，至七月底止，共三次。第一次套白色紙袋，第二次及第三次分別套白色及棕色紙袋，不套袋者爲對照。八月中旬至下旬調查袋之溫度變化。日間袋內之氣溫較外界氣溫可提高9℃,夜間袋內與外界之氣溫幾無差異。日間袋內溫度變化明顯地受到日照強度的影響。日間袋內相對溼度較袋外低5%至10%，夜間袋內與袋外之差異甚小。就整個試驗期間比較，最早套袋者，果實之生長率最低，但未達顯著差異。採收後一週進行品質分析。結果顯示果實之主要特性包括體積、果重、果形指數、比重、皮厚、果皮質地、糖度、風味等在各處理間均未達顯著差異。果皮顔色之差異主要爲明度（L值），套白色袋者較套棕色袋或不套袋者明度大，達到極顯著的差異。但此一顔色差異甚有限，並不易由肉眼察覺。
To investigate the effect of bagging on fruit growth and quality of ‘Wentan' pummelo, the fruits were bagged with white or brown paper bags on 24th May, 26th June und 25th July. Fruit sizes were measured on each days of bagging and on September 11th after the fruits were harvested. Temperatures inside the bags in different positions of the canopy were recorded from middle to late August.
The results showed that fruit characters including size, weight, specific gravity, fruit shape, rind thickness, rind texture, sugar content and flavor were not significantly different among the treatments. In day time the temperature differences inside and outside the bags can be as high as 9℃. The differences of relative humidities were 5 to 10%. The temperatures increased inside the bags were related to the intensity of solar radiation. The growth rate of fruits which bagged earliest was lowest, but that was not significantly different among the treatments.
The color of fruit peel was analyzed on one day and one week after harvesting. L values of the fruits bugged with white bag were higher than those of the fruits bagged with brown bag or without bagging, but the a and b values were nut significantly different among the treatments. These results explained that the fruits without bagging were a little dark greener than the other treatments, but the difference was not much that it can not be visually distinguished
(40(2):225-232)The Polyembryony and Identification of Zygotic Seedlings of Lemon (Citrus limon〔L.〕Burm. f.)
No full text在果實發育中期及成熟期分別調查Eureka及Lisbon檸檬種子之胚數，發現不同植株或不同花粉親授粉之種子，其平均胚數在2個以下，成熟種子之單胚比率達44％至68％。以糖橙（Sugar orange）、柳橙及枳殼分別授粉於檸檬，雜交苗與株心胚苗間以葉片形態鑑別之；枳殼授粉者，雜交苗率達73%，糖橙及柳橙授粉者，不同雜交組合之雜交苗率介於27％至56％間，此應與親本間之葉片形態差異程度有關。由不同時期之胚數及雜交苗率調查結果，檸檬可稱之為少胚性的柑橘，可做為雜交育種的母本。上述以葉片形態鑑定之雜交苗，於1990年2月至4月觀察新稍的顏色，大部份均為與父本相同之綠色，新稍帶有檸檬之紫紅色或淡紫紅色者，以枳殼授粉者僅11%，甜橙授粉者介於22％至30％間，顯示除葉片形態外，以新稍顏色或上述二者同時鑑定檸檬與其他柑橘之雜交苗當較容易。The number of embryos of Eureka and Lisbon lemon was investigated during the development of the fruits. Open-pollinated fruits were harvested on June 5 and on June 21, and hybrid fruits were harvested in early August. All the mean number of embryos per seeds were less then 2.0, and 40 % to 68 % monoembryo seeds of hybrid fruits were found. These indicated that lemon contain low degree of polyembryony. Zygotic seedlings of hybrid fruits were identified by leaf morphology, and seventy-three per cent zygotic seedlings of Eureka lemon crossed by trifoliate orange and 38 % to 56 % zygotic seedlings of lemon crossed by sweet orange were obtained. This variation might be influenced by the difference of leaf morphology among the pollen parents. The colours of growing shoot of these zygotic seedlings was observed from February through March in 1990, eighty nine to seventy per cent of the zygotic seedlings were green, and the others were purplish as the seed parent. The results showed that both the leaf morphology and the colour of young shoot could be used to distinguish the zygotic from nucellar seedings of lemon crossed by other citrus species
(36(4):367-371)Embryos Development of Shueh-ken Orange at Different Growing Stages
No full text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 stages and that of the smallest embryos (stage I) decreased significiently from 80 to 100 days after pollination, which implied that most embryos began to develop at the same time. The percentage of zygotic seedlings crossed by trifoliate increased as seeds were more mature, so it was recommended that seeds about to mature were preferred if embryos were induced to germinate with the help of embryo culture
