Studies on hastening the germination of some wild leguminous seeds by the sulfuric acid treatment

Abstract

The proper time treated with conc. sulfuric acid to break hard seed and hasten the germination were investigated, using the seeds of six wild leguminous plants. The results obtained were summarized as follows: 1. The proper time of conc. sulfuric acid treatment varied according to the kind of seeds. On Lespedeza juncea, 40min.: on Lespedeza cyrtobotrya, from 20 to 60min.: on Indigofera pseudo-tinctoria, from 20 to 40min.: on Vicia sativa, from 5 to 10min.: on Cassia mimosoides, 5min. and on Aeschynomene indica, from 5 to 60min. gave good results. 2. In these proper treatment, the germination were hastened and from 80 to 98 percent of the total germination weae obtained at the end of the sixth day and from 87 to 99 percent were at the end of the tenth day.
