Effect of the media type and auxin concentration on the growth of cuttings seedlings of pepper (Piper nigrum)

Abstract. Amanah S, Budiastuti MTHS, Sulistyo A. 2022. Effect of the media type and auxin concentration on growth cuttings seedlings pepper (Piper nigrum). Cell Biol Dev 6: 32-40. Pepper nigrum L.) is an export commodity has become one Indonesian sources income. It necessary to develop best cultivation for increasing production. Vegetative propagation been chosen in this research, using manure as part a hormone. The research aims find ideal grafting. conducted Manyaran Wonogiri, Indonesia, with RCB design consists two factors arranged factorial method. first factor kind (soil, soil + manure, husk), second auxin's (0 g/L, 12.5 25 37.5 g/L; 50 g/L). Observation variables are bud time, number buds, length bud, leaves, leaf width, roots, root, life percentage cuttings. Data were analyzed by F test at 1% 5% continued DMRT if treatment had significant effect. also regression there was interaction between treatments. longest found husk (12.28 cm) followed (10.57 (6.15 low level, respectively. study revealed that roots influenced concentration. g/L (15.14 cm), 0 respectively (12.05 cm, 7.72 7.67 5.75 cm). highest (7.78), (4, 3.43, 2.33). showed factors. shows parabolic response auxin. In beginning, decreased then increased same pattern Almost 100% have all concentrations. Soil auxins caused 33.33% 66.67% cuttings,
