(48(1):52-59)Adaptation of Persimmon Cultivars in Lowland Area of Taiwan

本試驗以5個本地品種及12個國外引進商業品種為材料，在農試所試種，調查植株生長習性及果實特性，調查項目包括：萌芽期、開花期、果重、果高、果寬、果色、果形、可溶性固形物、果實發育日數等。結果顯示，本地品種在萌芽期與開花期均較國外引進品種為早，且萌芽較整齊。果實成熟期以‘西村早生’最早，‘正月’最慢。果實發育日數本地種除‘南瓜柿’為158天外，其他約200天，均較晚熟；引進品種以‘西村早生’120天為最早，其它品種在152至187天之間。在果實性狀方面多數引進品種，所結果實較引進地區為小，果肉也較粗，顯然不太適合在台灣平地種植。Five Taiwan persimmon cultivars and 12 foreign persimmon cultivars were evaluated at TARI. Growth habits and fruit characteristics were tested including budbreak、blooming date、ripening date、fruit weight、fruit length、fruit width、fruit shape、fruit color、total soluble solids and fruit development period. The date of budbreak and blooming of Taiwan persimmon is earlier and more uniform than Japanese persimmon cultivars. The ripening date of ‘Nishimura wase’, FDP only 120 days, is earliest one than other cultivars, and FDP of the rest cultivans are counted from 152 to 202 days. Most of Japanese persimmon, were tasted much more fiber and smaller size under the growth condition of TARI. These cultivars are not able to cultivate very well in lowland area
