Abstract

GUEDES, Roberta Sales et al. Germination and vigor of Myracrodruon urundeuva Allemão seeds in different substrates and temperatures. Rev. Árvore [online]. 2011, vol.35, n.5, pp.975-982. ISSN 0100-6762.  https://doi.org/10.1590/S0100-67622011000600003.

Myracrodruon urundeuva Allemão belongs to Anacardiaceae family, whose plants can be medicinal, it can be used in leather tanning industry, tree planting in urban areas because of its great mechanic resistance wood. Therefore, the objective of this work was to determine methodologies proper to conduction of tests of germination and vigor of M. urundeuva seeds. The temperatures utilized were 25, 30 and 35°C (constant) and 20-30°C (alternate), together with the substrates sand, vermiculite, bioplant®, plantmax®, blotting paper, with seeds upon the paper and between paper sheets and towel paper, in the form of paper rolls. The experimental design was completely randomized, with four replicates of 25 seeds. The following parameters were analyzed: germination percentage, germination speed index, first germination count and length and dry mass of seedlings. The temperature of 30ºC and sand substrate are indicated for the conduction of the germination tests and vigor of the M. urundeuva seeds.
