Effects of seed vernalization and photoperiod on flower bud initiation of summer, spring, and winter flowering types of sweet pea (Lathyrus odoratus L.) [Japanese]

摘要

The effects of seed vernalization durations for 0, 10, 20, 30, 40 and 60 days at 1degreesC combined with subsequent 8-, 10-, 12-, 14-, 16- and 24-hr photoperiods at 15degreesC on the flowering time and the number of nodes to the first inflorescence of a summer, a spring and a winter flowering sweet pea were investigated.
