• 中文摘要： 使用大豆四個品種，於六十四年十一月十日播種於田間與溫室，生育期間調查花粉特性及農藝性狀。結果如下： 植株生長於田間者，發現花粉之發育需長期間始能成熟，花葯之裂開及花粉之飛散均不良，花粉發芽率低，不但花數少，發育正常之莢也少。農藝性狀分枝數雖多，但植株甚矮，莢數少，開花期晚，全生育期過長。 基於上述結果，認為臺中地區欲在十一月初旬播種大豆，除非有耐寒性強之生態型品種，否則似乎不可能。
• 英文摘要： Four soybean cultivars were seeded in thegreenhouse and field on November 10, 1975.Both pollen and agronomic characteristics ofplants were studied during the growing period. Plants grown in the field showed that pollendevelopment required a longer period. Anthersplit, pollen dispersion, pollen germinationability, number of flowers and normal pod setwere poor as compared with those grown in thegreenhouse. Plants also showed a tendency toincrease in number of branches but plant heightwas reduced: fewer in pod number; delay inflowering and long period of growth cycle. Results concluded from above showed thatit seems impossible to grow soybean at Taichungarea in early November unless a cold toleranceecotype of soybean is selected.
