Paratecoma peroba is a native Brazilian forest species of great economic and ecological interest, which is currently at risk of extinction owing to excessive wood exploration. The use of the mini-cutting technique could facilitate the vegetatively propagation of this species. The objective of the present study was to establish a vegetative propagation protocol for P. In the first experiment, were tested five concentrations of indolbutiric acid IBA; 0, 1, 2, 4 and 8 g. L -1 and two types of substrates sand and a commercial substrate based on ground Pinus bark, coconut powder, and mineral additives. The results showed that P.

Pongamia pinnata , commercially important tree species used to produce biofuels, is known for its multipurpose benefits and its role in agro-forestry. Present study examines the amenability of vegetative propagation and effect of maturation in candidate plus tree P. The performance of the cuttings was evaluated using SAS GLM software and the data were analyzed as a one-way classified data with and without sub sampling for inferring auxin concentration that can be included in programmes aimed at genetic improvement of the tree species.
