Abstract

Seeds of many plant species will not germinate for some time after they are ripe, even if they are placed under optimum conditions of moisture, light and temperature. They are in a dormant condition. Dormancy in small grains and some members of the grass family is a fmiliar phenomenon among seed technologists. The length of the dormant period varies from days to years, depending on species and variety. Dormancy is a powerful aid in the struggle for survival in species where a living plant would not survive a cold winter or a dry season. Some studies have indicated that sorghum [Sorghum bicolor (I.) Moench] seeds of sme varieties show dormancy when freshly harvested.
