Review on use of tetrazolium in seed viability and bioregulator in seedling emergence of araçá-boi (Eugenia stipitata McVaugh).

The objective of this study is to perform a bibliographic review of the published scientific material on the use of tetrazolium test and plant bioregulator in seeds of Eugenia stipitata, as well as in the emergence of its seedlings. Research on this species could reveal and record its production potential. E. stipitata is a fruit species native to the Amazon belonging to the Myrtaceae family. Undoubtedly, a prominent species potentially provides fruits with great benefits for human health and new alternatives for production systems. According to the bibliographic survey, the emergence of E. stipitata seedlings can exceed 180 days after sowing, while in the tetrazolium test the results can be obtained between 6 and 30 hours. In relation to seed physical and physiological dormancy, the plant bioregulator has potential to promote emergence of vigorous seeds and seedlings. Thus, the tetrazolium test can be an alternative to determine viability of Eugenia stipitata seeds. Different priming periods and concentrations of the tetrazolium salt solution are required for seeds of the genus Eugenia. Using the plant bioregulator can accelerate the emergence of seedlings of the genus Eugenia. [ABSTRACT FROM AUTHOR]
