Abstract
梨低需冷性新品系'SH-085' 嫁接於烏梨砧木上於遮雨的環境下種於栽培槽中，於由長日開始轉變為短日後的三個不同時期進行兩種不同乾濕程度的水分管理，而後於78年10月19日、11月3日、11月16日及12月1日分別取樣及除葉後再以高土壤水分含量(-0.01MPa~-0.05MPa)處理，觀察枝梢再生長及開花結果之情形並分析不同時期碳水化合物蓄積之情形。Pear clone with low-chilling requirement 'SH-085' were planted in containers under shelter, after being grafted on bird pear rootstocks. Two soil water status treatments were undertaken at three different stages after entering short days. Sampling and defoliation were done respectively on Oct. 19, Nov. 3, Nov. 16 and Dec. 1. And then the defoliated plants were treated with high soil water content (-0.01 MPa~-0.05 MPa) to observe the growth and to analyse the accumulation of carbohydrates at various stages.
