Gladiolus (Gladiolus grandiflorus) is one of the most important cut flowers in the world.this plant propagated by corm.For cut flower production in year round the production of cut gladioli should be take place in different location and different planting dates.In this experiment we studied interaction of cold treatment and different storage times and different storage temperatures on vegetative and reproductive behavior of gladiolus cv. Oscar.A factorial experiment that arranged in randomized complete blocks with 3 replication was done during 1381-1382 years . in this experiments we studied effect of chilling duration (4,6weeks) and storage durations (4,6,8 weeks) at different temperature (10,20,30oc) was studid on vegetative and reproductive characteristics of gladiolus corm c.v. Oscar.Results indicate that with increasing storage time and storage temperature flowering stem length decrease. on the other hand, increasing time of storage and storage temperature (up to 30 oc) can reduce corm decays . Increasing cooling time decrease duration between planting and flowering.
