Delaying the beginning of SD treatment increased
node and leaf number below the terminal inflorescence, however,
flowering was still accelerated compared with plants grown under
constant LD. When photoperiod treatment was started immediately
after germination, the duration of SD treatment interacted
with timing of SD treatment and cultivar to impact node number
below the terminal inflorescence. These results indicate variability
in impacts of the number of photoinductive cycles on flowering
and reproductive development across photoperiodic plant species,
cultivars and developmental stages.
