摘要

本試驗以橫山梨(Pyrus pyrifolia cv. Heng-San)爲材料，利用石臘、石臘膜、液臘、高黏度液臘處理切口，比較於25℃生長箱中離體枝條之蒸散量與萌芽率，及田間之嫁接成活率。結果顯示、離體枝條降低蒸散率處理之效果依石臘膜、石臘、高黏度液臘、液臘之順序遞減。於生長箱中同於水份供給充足，萌芽率與水份蒸散率並無直接關係，田間之試驗以石臘膜包覆嫁接切口之73%的成活率最高、而液臘及高黏度液臘與無處理之對照組相若，其成活率均低於5%。

Transpiration rate and budbreak rate of shoots in vitro of Heng-San pear in the treatments of covering the graft union with paraffin liquid, paraffin viscous, paraffin, or parafilm were measured at 25℃ incubator. Effect of treatments on reducing transpiration rate of shoots in vitro decreased in order of parafilm, paraffin, paraffin viscous, and paraffin liquid. There was no direct relationship between budbreak and transpiration, rate of water due to sufficient water support. In field experiment, the highest successful rate of graft union was 73% in parafilm treatment and was lower than 5% in paraffin liquid or paraffin viscous.
