Tree growth is an irreversible increase in biomass, volume, and number of cells. In the seedling phase, trees growth is very fast forming a linear or exponential curve and continues to slow down as they age. The rate of tree growth can be influenced by various treatments, including coppicing. Coppicing and applications of liquid smoke nutrition are presumably can increase the growth of new shoots. This study aims to determine the effect of liquid smoke on the growth of young plants and to determine which plants have the best growth response to the bamboo liquid smoke application. Research was conducted on February - April 2020 at ITB Jatinangor arboretum, Sumedang, West Java. This research was carried out by spraying bamboo liquid smoke to the post-coppicing plants with a concentration of 0 ml / l water (P0), 100 ml / l water (P1), and 125 ml / l water (P2) with three replications. The species tested were Acacia mangium, Mimusops elengi, Samanea saman, Gmelina arborea, Toona sinensis, Paraserianthes falcataria, and Manglietia glauca. Observations variable observed in this study include number of shoots, shoot length, shoot diameter, and number of leaves. Outcome data was measured by a completely randomized design. The best percentage increase with 100 ml / l water bamboo liquid smoke treatment on the variable number of shoots, shoot length, shoot diameter, and number of leaves respectively, namely, in Mimusops elengi by 60%, Paraserianthes falcataria (34%), Mimusops elengi ( 44%), and Samanea saman (75%). Meanwhile, the best percentage increase with liquid bamboo smoke 125 ml / l of water treatment on the variable number of shoots, length of shoots, shoot diameter, and number of shoots respectively, namely, in Mimusops elengi by 51%, Paraserianthes falcataria (51%), Paraserianthes falcataria. (80%), and Samanea saman (108%). Based on data analysis, the results of observation for eleven weeks showed that the application of 100 ml / l water and 125 ml / l water liquid bamboo smoke had no significant effect in increasing the number of shoots, shoot length, shoot diameter, and the number of leaves on experimented species. The most responsive species to the liquid smoke treatment on the number of shoots was Mimusops elengi, shoot length was Paraserianthes falcataria, shoot diameter was Mimusops elengi, and number of leaves was Samanea saman, while the least responsive species to the number of shoots was Acacia mangium, shoot length was Toona sinensis, shoot diameter was Samanea saman, and number of leaves was Acacia mangium.
