Pengaruh Gibberelic Acid pada Benih Jagung (Zea mas L.) yang Didera dan Tidak Didera Etanol Terhadap Daya Berkecambah Benih dan Aktivitas Enzym Amilase

Abstract

The experiment was conducted in the Seed Science and Technology Laboratory, Bogor ~ g r i c u l t u r a lU niversity on 1984. Accelerated aging was conducted by the method of Sadjad, using the IPB 77-1 Rapid Aging Machine. The influence of Gibberellic Acid (0, 250, 500 p p ) , dipping periode of GA (0, 5, 10, 15 hours), a r t i f i c i a l aging (95 percent etanol vapor) and various interactions of these factors on the germination and 4-amylase enzym activity of "Harapan Baru" corn (@a maye L.) seeds were determined. Gibberellic Acid increased the activity of .C-amylase enzym on treated and untreated seed l o t s , although there is no significant different on germination. The activity of 4-amylase enzym is significantly influenced by the period of dipping, but the concentration of Gibberellic Acid did not affected.
