Abstract

This experiment was carried out in the Horticulture nursery unit of the Department of
Agronomy and Landscape Design, Babcock University Nigeria. 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 samples of the vegetable seed were acquired from the
experimental fields of National Institute of Horticulture (NIHORT) in Oyo state. The seed
were subjected to seven temperature regimes including: (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 at 90oC for 5 and 10mins exposure. The seed germination
at the dry heat treatments of 40oC, 50oC and 60oC are not significantly (P<0> however, those of 70oC, 80oC and 90oC heat treatments are significantly different at (P<0> The seedling emergence at dry heat treatments for the control are not significant at 40oC and
50oC heat, while those of: 60oC, 70oC, 80oC and 90oC treatments are significantly (P<0> different. These experimental trials show that Corchorus olitorius seed can tolerate high dry
oven heat treatment and still remain viable at temperature as high as 90oC.
