Use of different conditioning agents and quality evaluation of two lots of annatto (<i>Bixa orellana</i>) seeds

Abstract: Devido à baixa germinação de sementes de Bixa orellana L., há a necessidade de se testar diferentes técnicas que viabilizem sua reprodução, como o condicionamento fisiológico. O objetivo do presente trabalho foi caracterizar a germinação de dois lotes de sementes de urucum sob efeito do condicionamento fisiológico. Para isso, sementes de dois lotes (recém-colhido e armazenado) foram submetidas ao condicionamento fisiológico em solução aerada de: 1) água deionizada; 2) água catódica; 3) nitrato de potássio a 0,… Show more

“…A fact also observed in annatto seeds (Bixa orellana) stored for more than 10 years. However, in both cases, improvement was observed in the other germination variables when using this salt (Kreuser et al, 2016;Fernandes et al, 2021). The use of KNO 3 is generally indicated for promoting germination and overcoming dormancy in different types of seeds, including forage (Bareke, 2018;Golmohammadzadeh et al, 2020;Ali et al, 2021;Pereira et al, 2021).…”

“…In the 1970s, an Active Germplasm Bank of forage species was implemented in the Caatinga experimental unit of the Empresa Brasileira de Pesquisa Agropecuária (Embrapa Semiárido), including several buffelgrass genotypes, which was the most outstanding among the evaluated species, due to its greater potential for forage production (Oliveira et al, 1999). Based on this, an Active Germplasm Bank was implemented for Cenchrus species and, in 2009, it integrated the National Platform of Genetic Resources, in the Vegetal Genetic Resources Network -Vegetal Network (Embrapa Cenargen, 2009;Jank et al, 2021). The improvement of these plants is essential to obtain information and develop cultivars that present desirable characteristics considering local needs.…”
