QUALIDADE FÍSICA E FISIOLÓGICA DE SEMENTES DE SORGO GRANÍFERO: REVISÃO BIBLIOGRÁFICA

Abstract

Sorghum is a versatile plant, classified into five types of production: grain, forage, sugar, broom and biomass. The 2020/21 Brazilian grain harvest resulted in a production of approximately 2,100 million tons of this grain and, due to its great genetic variability, studies on genetic improvement have been carried out to develop varieties and hybrids, with seed quality being a key factor in this process. Seeds can undergo physical and physiological changes, which can compromise their establishment in the field and, therefore, knowing their quality is so important. The objective of the present work was to present a bibliographic review about the physical and physiological quality of grain sorghum seeds in Brazil and the main research results within this context. For this, a bibliographic search was carried out in four bibliographic databases — Scielo, Science Direct, Scopus and Google Scholar, as well as in the official website of the Associação Brasileira de Tecnologia de Sementes, adopting the use of free terms, without the use of controlled vocabulary. Duplicate references were excluded, selecting materials published between 1982 and 2022. There are still few studies on the quality of grain sorghum seeds, and it is necessary to go deeper into these characteristics.
