摘要：
The aim of this study was to assess the water supply provided by different alternative substrates as well as to analyze its efficiency in the sanity and in the in vitro germination of Pinus taeda L. seeds. The seeds were inoculated in filter paper, hydrophile cotton and agar-water medium. Water absorption by seeds was assessed for 3, 6, 9, 24, 48 and 72h and, later, at 21 days of cultivation and contamination by microorganisms was determined. Water absorption, based on the percentage increase which occurred in the weight of seeds, was higher in filter paper and hydrophile cotton. The best germination rates were obtained with filter paper and agar-water. However, agar-water presented the highest contamination rates. Due to water loss in the substrate filter-paper during cultivation, it is suggested the use of cotton because of the low contamination rates observed.
