1. In a study of the relation between sowing time and the date of ear emergence in rice (Oryza sativa), the Aman and non-Aman varieties were found to be fundamentally different in their flowering reaction; while the former tend to flower mainly in the fall and rarely in the spring, the latter flower evenly throughout the year when sown at different dates. 2. It is suggested that all Aman varieties are to be regarded as short-day plants, while the other varieties do not form a homogeneous group as to their photoperiodic reactions.
