INFLUÊNCIA DO TAMANHO-PESO DA SEMENTE NA PRECOCIDADE DE EMERGÊNCIA DE BACURIPARI (Rheedia gardneriana)

Abstract

The present work was realized with the objective to evaluate the percentage of emergenceand the emergence velocity index (EVI) of bacuripari seeds, being accomplished of lath house conditions, with 50% of luminosity, using plants that came from the Germplasm Bank of the Department of Vegetable Production, of Faculdade de Ciências Agrárias e Veterinárias - UNESP - Campus of Jaboticabal, São Paulo state, Brazil. The fruits were picked totally ripe, the seeds were extracted, washed, placed to dry and conditionedin plastic boxes, having vermiculite as substrate. The treatments was characterized by the size of the seeds: very big, big, medium and small, determined by the medium weight of the 50 seeds (in grams), being 63,634; 42,787; 25,631 and 9,508g respectively. The values of the percentage of emergence were transformed in arc sen . The averages were compared by the Test of Tukey, with 5% of probability. Analyzing the results was possible to observe that the smallest values, so of the percentage of the emergence (2,30%) and for the GVI (0,002) were obtained for the seeds with a small size, differing significantly of the other treatments, where was verified values of percentage of emergence of 83,33; 86,25 and 77,00% and GVI values of 0,102; 0,107 and 0,105 for the very big, big and medium, respectively. Can be concluded that there is interference of the seed's size-weight in emergence of this specie.
