Improving the germinability and viability of forage legumes by physical and chemical treatment
1987
Caccam, G.A.
Two experiments using split plot in CRD [Complete Randomized Design] were conducted to evaluate the germinability and viability of six varieties of forage legumes. The physical treatments consisted of sand papering, soaking in hot water and oven-heating at varying temperatures and durations. Chemical treatments involved the use of H2SO4 and HNO3 at varying durations of exposures. Result showed that sand papering was the most effective in initiating germination in Centrocema and Cv Archer. Also, soaking in hot water at 55 deg C remarkably increased the germinability of Cv Archer. Cook was more responsive to soaking at 55 deg C and oven heating at 80 deg C. Khonkaen on the other hand, proved to have higher germinability when the seeds were soaked in hot water at either 55 deg C or 80 deg C. Germinability of Seca and Verano was relatively low at all kinds of physical treatments. Likewise, percent hard seeds were markedly reduced by sandpapering in Centrocema and Cv Archer while soaking at 55 deg C and oven-heating reduced the percent hard seeds in Cook. Percent hard seeds in Khonkaen, Seca and Verano were neither reduced or increased.
