Studies on the physiological quality of stored sorghum seed concerning germinative parameters

Abstract

Seed germination and the field crop stand that is necessary for the higher yield area ffected by the physiological quality of the seed i.e. the seed viability and vigor. The Rabi sorghum seed is considereda”moderate storer” as its viability fluctuates drastically under warm and humid storage conditions. In the present research,we evaluated the stored Rabi sorghum seed material for its physiological quality particularly vigor and viability as germinative evaluation criteria. The seeds of Rabi sorghum variety, SPV-1411, SPV-1595, CSV-22R, CSV-29R and SPV2407 were stored in air-tight plastic containers and kept under ambient laboratory conditions were evaluated for germinative criteria. The storage of seeds resulted in the deterioration of seed vigor as evidenced by the decline in the various parameters investigated.
