Germinação e emergência de plântulas associadas ao tamanho e peletização de sementes de quinoa

Abstract

This work has been performed with the aim of verifying the existing relation between the size of the quinoa seeds and their pelleting in lab germination and emergence of seedlings in field. First, the experiment has been conducted in laboratory, using completely randomized design (DIC) with incomplete factorial scheme 2 x (4 or 3). Then, it has been conducted to field, using randomized block design (DBC) with subdivided portions, in four repetitions and with scheme of 2 x (3 or 2). The statistical analyses have been calculated using the software R, followed by the analysis of variance followed by the Tukey average test in 5% of error probability. According to the performed tests, when put into lab environment, bigger quinoa seeds present higher germination performance than smaller seeds. When the seeds were put into field condition, no matter the size of the seed or its pelleting process, there was no meaningful difference in the index of emergence speed.
