臺灣開英種鳳梨主要系羣之分佈與特性

Abstract

(1) 臺灣開英種鳳梨自1922年大量引入後，即極力繁殖推廣，迄今已佔全島鳳梨栽培面積七千餘公頃之88%，成為製罐之主要品種。 (2) 由於大量繁殖推廣結果，只注意苗量的增殖，而忽略苗質的選擇，以致品系混雜，良莠不齊，光復後農林廳，農復會，鳳梨公司及鳳山熱帶園藝試驗分所等機構為增加鳳梨生產，提高鳳梨品質，遂著手鳳梨選苗工作，在選苗工作當中始發現開英種鳳梨有四個主要系羣。 (1) Since the introduction of Smooth Cayenne pineapples to Taiwan in 1922, great quantity of propagation and extension have been carried on among growers. Now, 88% of the present 7,000 hectares of pineapples are Smooth Cayenne variety which is the leading canned pineapple in Taiwan. (2) As a result of large-scale propagation and extension, attention was concentrated on the quantative increasement of planting materials while selection of better seedling was neglected. Strains were mixed and inferior mutation have been prevailed. After the restoration of Taiwan, in order to increase production of pineapple industry and improve the quality of pineapple fruits, the Department of Agriculture and Forestry, JCRR, Taiwan Pineapple Corporation and Fengshan Tropical Horticultural Experiment Station began to select pineapple seedlings in Taiwan. Four pineapple types of Smooth Cayenne variety were discovered in the course of this selection.
