Abstract
Gamma irradiation has been found to be very useful technique for crop improvement. Besides, the proper use of induced mutation in plant breeding has become a profitable approached. This investigation was carried out to determine the LD5o and effect of gamma irradiation on the germination, plant height, survival and dry weight of plant shoot of irradiated seeds of tomato and okra. This study was not intended to compare differences among the performances of these plants. Seeds of tomato (Lycopersicon esculentum) and okra (Abelmoschus esculentus) were irradiated with varying doses of 300,400,500, 600 and 800 Gy using gamma cell irradiator facility at Malaysia Institute of Nuclear Technology (MINT). For each dose, ninety seeds were used. These treatments as well as ninety seeds of control (unirradiated seeds), were planted in sand beds at Horticulture Unit, University Putra Malaysia Bintulu Campus. This study revealed that the number of germination, plant height, survival and dry weight of plant shoot of tomato and okra decreased with increasing radiation, with 800 Gy having profound effect on these variables. The LDso for survival and germination of the doses for both plants were consistent with literature. Irradiating tomato and okra seeds above 600 Gy caused mortality in these plants.
