Abstract

The experiment was conducted on December, 1983 at the greenhouse of the Department of Agronomy, Kasetsart University, Bangkok. Soybean varieties S.J.2, S.J.4, accessions KU.3, KU.4 and Ku.5 were grown in 16 hours photoperiod for 30, 45 and 60 days before subjecting the plants to the normal photoperiod and compared the growth and flowering habits with the controlled plants. It was found that the period between photo induction and the appearance of flowers, and flowering period, decreased as the vegetative growth of plants were lengthen. Moreover, the plants which had longer vegetative growth produced more flowers than the controlled one.
