Studies on lifting of corm after flowering on corm and cormel production and incidence of corm rot in gladiolus

Higher weight and diameter of corm and weight of cormels per plant were obtained with the treatment lifting of corms at 105 days after flowering. Significantly higher corm weight was lost (30.97%) during storage for sixty days with the treatment lifting of corm at 30 days after flowering. In other treatments, namely, lifting of corm at 45, 60, 75, 90, 105 and 120 days after flowering, the percentage of corm weight lost during storage was 24.84, 24.22, 22.99, 22.48, 22.40 and 20.96 per cent respectively. Different dates of corm lifting did not have significant effect on number of cormels produced per plant. Significantly higher quantity of healthy corms was obtained by lifting them at 60-75 days after flowering.
