水稻與陸稻在水田栽培下期作間生長及產量之差異

Abstract

本文旨在探討水稻與陸稻兩生態群在水田栽培下生長與產量之差異，並比較其在不同栽培季節之表現，試驗於1994年一、二期作在臺灣省農業試驗所農場進行。由生長性狀之變方分析發現，一期作族群50%抽穗期時兩生態群間僅植株分蘗數差異顯著，至收穫期除植株生質量外其餘性狀均差異顯著：二期作株高與分蘗數於抽穗期及收穫期時皆差異顯著。Experiments were conducted to study the difference in growth and yield between the lowland and upland rice (Oryza sativa) varieties grown under well-watered conditions and to compare the variations in ecotypes and varieties in the first and the second cropping seasons in Taiwan.
