Conteúdo: | According to photoperiodic and temperature responses, the 48 test cultivars can be classified as follows: Stable determinate growth types (Sd types): These lines are photoperiod insensitive. Under short-day and long-day conditions, days to flowering is almost same, flowering period is short, and the increase in node number after first flower anthesis is insignificant. Final node number is similar, regardless of temperature and photoperiod. Unstable determinate (indeterminate) growth type (Ud type): These materials are also photoperiod insensitive. Days to flowering is almost the same under both photoperiods, but flowering periods are fairly long and the increase in node number is rather large. Number of nodes is slightly higher under long-day conditions than under short-day conditions; node number is higher at lower temperature. Quantitative short-day cultivars: Plants can initiate flowers and produce pods under both photoperiod, but number of days to flowering and the resulting number of nodes are greater under long-day conditions than under short-day conditions. The number of nodes is also greater at higher temperatures. Unstable, determinate, photoperiod-insensitive cultivars have higher yield potentials than stable, determinate growth types that require high plant population densities to produce high yields.
