QUALITY OF Schizolobium parahyba SEEDS AND SEEDLINGS FROM RIO GRANDE DO SUL, SANTA CATARINA AND PARANÁ STATES
Main Article Content
Abstract
This research aimed to study the vigor and the quality of Schizolobium parahyba seeds from samples of three different states, Rio Grande do Sul (RS), Santa Catarina (SC) and Paraná (PR) and to evaluate the seedlings quality produced by these seeds. The seeds were submitted to evaluations of moisture content, germination, vigor and healthy. The seedlings quality was evaluated by hard seeds, dead seeds, emergence, seedling height, root length, collar diameter, fresh and dry weight of seedlings. On the seeds evaluations, the samples from SC and PR presented better results for first count of germination, dry matter and accelerate aging. The fungi associated to the seeds were Aspergillus sp., Alternaria sp., Penicillium sp. and Trichoderma sp. About the seedlings evaluations, seeds from PR showed the bests results when the differences between tests were significant (emergence, root length and dry weight of seedlings). Some of the labs variables had correlation with the seedlings variables.
