<![CDATA[Olyfia Rosalina "The Effect of Growth Regulatory Substances (ZPT) and Fruit Maturity Rate on the Germination of Arabica Coffee (Coffea arabica L.) Variety Gayo 1". This research was conducted in the laboratory of the Faculty of Agriculture, Gajah Putih University, Pegasing sub-district, Central Aceh district, with an altitude of 1,200 m above sea level. This research was conducted on 22 October 2019 to 20 December 2019. This study aimed to determine the effect between giving growth agents (ZPT) with treatments of 100 cc / l (T1), 150 cc / l (T2) and 200 cc / l (T3) and to determine the effect of the ripeness level of Arabica coffee fruit. treatment of red fruit (B1), reddish yellow fruit (B2) and brown fruit (B3). On the germination of Arabica coffee seeds varieties Gayo 1. The use of growth regulators (ZPT) has a very significant effect on the potential for growth, germination, wet weight and dry weight of sprouts, the best use of growth regulators (ZPT) is the treatment of 200 cc / l (T3). The level of ripeness of the coffee cherries had a very significant effect on the potential for growth, germination, wet weight and dry weight of sprouts, the level of ripeness of the best coffee cherries with the treatment of red fruit (B1). There is a very real interaction with the treatment of growth regulators (ZPT) and the level of fruit maturity in the growth potential test. The best results were obtained at the interaction between 200 cc / l (T3) treatment and red (B1) or (T3 B1) fruit ripeness.]]>
