Abstract
取秈稻及稉稻品種各二，種植於臺中地區，比較一二期作下產量變異，特別是不稔實率變化以了解期作對水稻不稔實率的影響。1.臺中地區二期作水稻產量顯著低於一期作，稉稻(臺南5號、臺農52號)系由於穗數減少；秈稻(臺中秈3號、烏毛種)則因穗數減少與稔實率低下所致。
Field experiments were conducted to compare the distribution of un-filled grains between the first and second crop seasons of 1980 in Taichung area. Four cultiuars. Tainan 5 and Tainung 52 (japonica) as well as Taichung Sen 3 and Wu Mao-Chung (indica) were used as material, the results obtained are summarized as following:
1.Generally, the grain yield of the second crop was lower than that of the first crop for all tested cultivars.
