Andaliman is a typical plant in Sumatera Utara that hasn’t been widely cultivated because it’s difficult to germinate. The aim of this research was to study the effect of giving an electric field to the metabolism of andaliman (Zanthoxylum accanthopodium DC) seeds which contributes to accelerating germination. Research conducted at the Laboratory of Plant Ecology, Tissue Culture Laboratory and Molecular and Genetic Laboratory of the Faculty of Agriculture, Universitas Sumatera Utara from June to July 2018 was arranged in a complete non-factorial randomized design repeated three times. Seeds are given by an electric field for 18 days with a voltage of 324 volts. The results of this research showed that the electric field treatment and differences in fruit colour not different significantly on seed metabolism in accelerating germination after do analysis of proteins, APX, SOD and electrical conductivity. Descriptively the highest average of APX was showed on without electric field: red colour seeds 2.39 μM/min/mg protein (P1). The highest average of SOD was showed on with electric field: red colour seeds 485.27 unit/mg protein (P4). The highest average of electrical conductivity was showed on without electric field: red colour seeds 6733.33 μS (P1).

Population F4 is a segregated population the character of certai, so important to know the parameters of genetics. The purpose of our research to determine action of gene and the values expected heritability population F4 (Silopuk X Fatmawati). The research has been from month of October 2017 to February 2018 in land farmer Padang Limau Manis. The research use method experiment without repitition the head to row with analysis Z Skewness and Z Kurtosis. The genetic material of this research is rice seed on the F3 generation from the selection of pedigree crosses between silopuk and Fatmawati superior variety and the other seeds were Silopuk cultivar and Fatmawati superior variety as control. The research data showed that Z test skewness and Z test Kurtosis for whole characters observed were dominant controlled by minor genes. The character age of flowering, plant height, length of panicle and percentage filled grain per panicle were controlled by many gene additive. The broad heritability value for all character observed in the F4 population ranged from 0.01-0.99 with low to high criteria.
