Abstract

A study was conducted on the effects of chemicals and mechanical scarcification on freshly extracted and stored chico and pill seeds. Percent germination of chico rseeds was increased by storage for one month, application of 200 ppm gibberellic acid, soaking in water, and cracking the seedcoat. Sulfuric acid treatment, on the other hand, reduced percentage germination. In chico seeds, germination was hastened by ethephon, delayed by naphthalene acetic acid and gibberellic acid and unaffected by benzyl adenine.

Germination in pili seeds was increased by providing an after-ripening period of one month and by producing a slight crack on the hard seedcoat but not by treating with sulfuric acid. Moreover, removal and cracking of the seedcoat induced early germination time.
