Conservation, Disease-indexing and Utilization of Pathogen-free Citrus and Banana Genetic Resources in Taiwan Taiwan Agricultural Research Institute
Hong-Ji Su; A-Shiarn Hwang; Su-Yin Lee; Chih-Ping Chao.
[[abstract]]Virus and virus-like diseases (greening) of citrus and banana have been causing considerable damage to fruit production worldwide due to their systemic invasion and common spread through infected budwoods, vegetatively propagated seedlings, and transmission by insect vectors. The heat-tolerant form of greening locally known as Huanglungbin (HLB) in China has seriously affected citrus trees in the tropical/ subtropical regions of Asia, and recently in the North and South America. The HLB caused great damage to the citrus industry by shortening tree lifespan and lowering fruit quality. Citrus tristeza virus (CTV) is the most common and destructive virus in the western hemisphere, and has a worldwide distribution. Citrus tatter leaf capillovirus...

小年全株蔬果對檸檬後續產量的影響 Taiwan Agricultural Research Institute
黃阿賢; A-Shiarn Hwang.
[[abstract]]在嘉義地區,‘Eureka’檸檬於小年之四月中旬生理落果期間完全疏果,並無促進開花、調節產期之作用。疏果者當年大幅減產,次年五月及九月之產量較對照植株高,其中五月者有顯著差異,九月者未達顯著差異。顯示完全疏果對產量之影響,至次年之主要產期(九月)已不明顯。枝梢修剪量,不論新梢(一年生以內)或老枝(一年生以上),疏果植株平均分別較未疏果者多,但未達顯著差異。

砧木種類對桶柑植株生長、產量與品質的影響 Taiwan Agricultural Research Institute
黃阿賢; 洪士程; A-Shiarn Hwang; Shih-Cheng Hung.
[[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...
