摘要

本研究目的在探討孤挺花雙鱗片繁殖法之生產力，試驗採用孤挺花「Red Lion」品種三年生鱗莖（周徑20－22cm）以米字形八分割切開後，切取雙鱗片為試驗材料，於透明塑膠封口袋中培育。試驗結果顯示不同成熟度的雙鱗片小鱗莖形成率以PII、PIV最好，分別達100%及95.8%；PI及PIV次之，PV、PVI最差，僅有45.8%及54.2%。在比較切法（1/16、1/8、1/8+1及1/8+2切法）上，小鱗莖形成率以1/16切法最差，僅有80.3%，與其他三組均呈顯著差異；小鱗莖平均形成數則以1/8+2切法最多，平均可得1.57個以上；1/8及1/16切法表現最差，平均形成數在1.2個以下；1/8切法可得到較重、較大的小鱗莖，平均重在0.53g以上，1/8+1、1/8+2切法表現次之，1/16切法小鱗莖平均重最輕。不同基盤寬度（10.5－12.0、12.0－13.5、13.5－15.0、15.0－16.5、16.5－18.0、18.0－19.5 mm）雙鱗片配合1/8+2切法對小鱗莖形成之影響，各處理間小鱗莖形成率均可達100%，而小鱗莖平均形成數則呈顯著差異，隨基盤寬度增加，小鱗莖形成數也增加，基盤最寬之6.0－6.5 mm處理組平均可達3.92個，最小之3.5－4.0 mm處理組平均亦有1.39個；球徑大小各組差異均不顯著。

Three-year Hippeastrum hybridum Hort. 'Red Lion' bulbs of 20 to 22 cm circumference, which were cut into eight parts evenly (1/8), were used to study scaling. The twin-scale were treated and were placed into a clear plastic bag for incubation. The bulblet formation rate of the middle layer twin-scales (PII-PIV) was the highest, then that of outer (PI), and that of the inner (PV-PVI) twin-scales was the least. The number of bulblet obtained by using 1/8+1 or 1/8+2 cutting method was larger than that of 1/8 conventional cutting method, and that of 1/16 cutting method was the least. However, the bulblet form both of 1/8+1 or 1/8+2 cutting methods could reach the planting size (dia. 7.4 mm). As the base width of twin-scaling increased, the number of bulblet formation increased, but no significant difference was found on weight of bulblets.
