Abstract

This effect of high dry heat treatment of three accessions of Corchorus olitorious seeds on seed germination, seedling emergence and seedling vigour was evaluated in the laboratory and horticultural nursery of the School of Agriculture and Industrial Technology, Babcock University Nigeria. The aim was to determine the most suitable dry heat treatment for early seed germination and seedling emergence of C. olitorious seeds. The experiment was a 3 X 5 factorial arrangement using completely randomized design (CRD). The treatments consisted of five temperature regimes (800C, 900C, 1000C, 1100C and 1200C) with a control (untreated seeds); and heat exposure time of 5 minutes, where three accessions of C. olitorious seeds were subjected to the temperature treatments for the time periods in order to break seed dormancy before sowing. There were significant differences in the viability and vigour responses of the crop seed to the varying heat treatments; where seed germination and seedling emergence were initiated at 800C, but optimum seed germination, seedling emergence and seedling vigour index were obtained at 1200C for 5 minutes of exposure. There is therefore indication that there may be corresponding increase in seed germination and seedling emergence of C. olitorious seed if it is exposed to higher temperature treatment(s) for 5 minutes.
