ABSTRACT: The prevalence of fungi associated with seeds of
some selected local flowers namely cosmos, marigold, calendula, and periwinkle collected
from three different locations (Arboriculture Garden, Ramna Park Garden, and Horticulture Garden) in Dhaka district and four hybrid flower seeds (African
marigold, cockscomb, petunia, and Portulaca) collected from Momin Beej
Ghar, Dhaka district were recorded. The results showed that the highest percent
germination (91.38%) of cosmos was obtained from Horticulture garden’s seed, marigold (95.25%) obtained from
Arboriculture garden’s seed, and
calendula (65.88%) periwinkle (79.38%) obtained from Ramna park garden’s seeds.
But in the case of hybrid seeds, African marigold showed the highest percent seed
germination (98.25%). The Horticulture garden’s seed was better than the others
considering the incidence of fungi in all local flower seeds tested. But periwinkle was the lowest affected seed
(12.58%, 12.20%,
8.07% incidence) and marigold was the highest affected seed (40.31%, 35.33%, 31.33% incidence) collected
from Arboriculture Garden, Ramna Park, and Horticulture Garden, respectively. But in hybrid flower seeds, the lowest fungal infection
(3.14%) was recorded in Portulaca and
petunia seeds whereas the highest (6.20%) was in African marigold seeds.
