Abstract

The aim of the study was to determine the effect of temperature on the seed germination and seedling emergence of Corchorus olitorius. About 2.5kg seed were subjected to seven temperature regimes (40oC, 50oC, 60oC, 70oC, 80oC and 90oC) for 5minutes and 10minutes to break the seed dormancy. The seed germination test was carried out in petri-dishes following the oven heat treatments, while the seedling emergence test was carried out in a concrete trough and trays filled with sterilized soil. The germination was initiated at 40oC and seedling emergence initiated from the control while optimum germination was obtained by treating seeds at 90oC for 5 and 10mins exposure. The dry heat treatments of 40oC, 50oC and 60oC are not significantly (P<0>
