Effect of Genotypes and Pre-Sowing Treatments on Seed Germination Behaviour of Jatropha
The objective of the study was to explore the effects of pre-sowing seed treatments on germination behaviour and to assess the possibilities of increasing the germination rate of Jatropha curcas. Seeds of twenty jatropha accessions obtained from seven different sources were subjected to three pre-sowing treatments viz., control (T „): unsoaked seeds directly sown in the polybag and apply water up to saturation; TV seed placed on filter paper in the petridis and moistened once with the water; and T2: seeds kept under stone sand and moistened once with the water. Seeds in T, and T2 were kept for 72 h before sown in the polybag. The study was conducted in the Glass House of Plant Biotechnology Laboratory, Universiti Kebangsaan Malaysia. Study revealed that pre-sowing treatments significantly (p< 0.01) enhanced seed germination parameters of Jatropha.
