Emergence and Initial Development of Erythroxylum pauferrense Seedlings under Different Substrates

Erythroxylum pauferrense Plowman is an understory species native to Brazil, with great importance in the conservation of genetic resources and used as a food source for animals regions where occurs. The currently listed category EN (endangered). objective this work was evaluate effect different substrates on emergence initial growth E. pauferrense. experiment carried out protected environment, belonging Plant Ecology Laboratory Federal University Paraíba, Areia-PB, Brazil. were: sand; sand + vermiculite proportion 1:1, 3:1 1:3; vegetal land; land vermiculite; Bioplant®; Bioplant® ratio 1:3. experimental design completely randomized, 16 treatments (substrates) four replications 25 seeds. percentage emergence, first count, speed index, mean time, relative emergency frequency were evaluated. substrate provided best results carrying vigor tests seedlings, being most suitable seedlings species.
