Abstract
本試驗目的在瞭解開花習性對毛豆莢果產量之影響，分析合格莢與不合格莢之成因及在植冠層之分佈，以提供選種之參考。試驗採用高雄選一號、綠光、白鶴之子及雪之下等四個品種為材料，完全逢機排列設計，三重複，於1989年秋及1990年春種植於國立中興大學試驗農場”試驗結果顯示四個參試品種均以第一花群單一莢果較重，合格莢比例高，多分佈於植冠層之中、上層三分之一節位，愈晚開之花群，其單一莢果重較輕，合格莢比例低，分佈於植冠層之中、下層節位。因此選擇始花後15天內開花較多，結莢率高，且分佈於植冠中、上層三分之一較多之品種，可有效的增加毛豆合格莢產量。
The purpose of this expriment was analyzed the relationship between graded pod yield and flowering behavior in vegetable soybean. The vegetable soybean varieties (Kaohsiung selection No.1, Shirozurunoko, Ryokukou and Yukinoshita) were used in this experiment. Results showed that yield of pods from the earlier flowers were higher than those from the late flower. Within fifteen days of initial flowering, most graded pods were formed which were located mostly on the middle to upper level of the plant canopy. Those flowers occurred after fifteen days of initial flowering were located on the lower one-third portion of the canopy and tended to produce off-graded pods. It is therefore suggested that high-yielding vegetative varieties is characterized by the ability of producing more flowers on the middle to upper level of the plant canopy within fifteen days after initial flowering.
