ENRAIZAMENTO DE ESTACAS DE CROTON SACAQUINHA CROIZAT EM DIFERENTES SUBSTRATOS ORGÂNICOS

de de copas, subtropical, tropical O projeto foi realizado objetivo analisar espécie Croton sacaquinha Croizate, que tiveram delineamento totalmente casualizado, com quatro (4) repetições de dez (10) parcelas para cada substrato. Com isso, chegou-se ao resultado de que o enraizamento ocorreu melhor no composto orgânico peneirado, não havendo tanta disparidade entre os tratamentos e, além disso, ocorreram aparecimento de fungos em algumas estacas. ABSTRACT The Croton sacaquinha Croizat, popularly known as sacaquinha due to its structure is similar to the sacaca, is a plant with high medicinal value, belonging to the Euphorbiaceae family and classified within the genus Croton, having its stature represented as a tree with a characteristic low shrubby shape with crown formation, being of subtropical, tropical origin and the Amazon region. The project was carried out at the Universidade Federal Rural da Amazônia at the Belém Campus, with the objective of analyzing the rooting of the species Croton sacaquinha Croizte, in a totally randomized design, with four repetitions of 10 plots for each substrate. The results showed that rooting occurred better in sieved organic compost, and that there was not much disparity between the treatments.
