Abstract

Four treatments were included in this experiment: A. Scions from trees cultivated at high altitude were grafted on the low altitude grown Hongshan pear stock. B. Scions resulted from grafting between Hongshan pear and Shinseiki pear in the previous year were grafted once more on Hongshan pear at low altitude. C. Scions from trees planted at high altitude were grafted on Sungmao pear stock. D. Scions from trees planted at low altitude were grafted on Sungmao pear stock. Scions of treatment B and D were stored for about 600 hours at 5â to break dormancy. Results indicated that scions from trees cultivated at low altitude could be used for â parasitic-graftingâ and fruit prodution at the same sea level. The fruits thus obtained have the same quality as those of the other treatments, this seems to indicated that scions which are needed for fruit production at low altitude, will no longer rely on the supply of Lishan area. Among these four treatments, fruits derived from scion of Sungmao pear stock seems to have better quality than those from Hongshan pear.\ud Note: Scion means scion of Shinseiki with flower bud.本試驗共有四個處理:A為高海拔地區栽培之新世紀梨,具有花芽之枝條作接穗寄接在橫山梨砧上。B為去年寄接於低海拔地區橫山梨上發生之新世紀梨枝條,取其具有花芽者作接穗,寄接於橫山梨砧上。C為高海拔新世紀梨接穗寄接在松茂梨砧上。D為低海拔新世紀梨接穗寄接在松茂梨砧。其中B、D二處理之接穗均經在5℃之低溫下冷藏六百小時左右以打破休眠。結果發現去年寄接在低海拔梨砧上之新世紀梨所產生之枝條,其具有花芽者亦可供作寄接生產接穗之用,其果實之品質與以高海拔接穗寄接者無顯著差異,證明今後寄接生產所需之花芽接穗可不必完全仰賴梨山地區之供應。其中以松茂梨為砧木者其果實品質似橫山梨砧著為佳
