不同播種期有限型及無限型大豆生育與產量的影響

Abstract

本研究以十個有限型及無限型的臺灣大豆栽培品種（系）為材料，於1992年春作分三個時期（一月中旬、一月下旬及二月中旬）種植，進行播種期試驗，探討對植株農藝與產量性狀的影響。變方分析結果顯示兩種型態大豆品種之產量、營養生長日數、生殖生長日數、成熟期株高、營養生長（開花）期株高、有限型品種之生殖生長期間株高伸長長度、百粒重、有限型品種之節間長度及無限型品種之主莖莢數等性狀均受播種期之顯著影響，其餘產量性狀所受的影響則不顯著。This study was conducted in the spring crop season of 1992 to investigate the effect of planting date (mid-January, late January, and mid-February) on the development and yield of 10 determinate and indeterminate soybean cultivars. Combined analysis of variance indicated significant planting date effects on the following characters: grain yield, vegetative and reproductive growth duration, plant height at initial blooming and maturity, 100 seed weight, plant elongation during reproductive growth and average internode length for determinate cultivars, and pod number on main stem for indetrminate cultivars.
