Abstract
The practice of storage is one of the most widely used strategies to preserve seed quality, thus contributing to the preservation of the genetic material of many species.
Seed properties during storage may undergo various changes involved in the deterioration process.
Temperature, water content, and storage environment are particularly relevant to such changes.
This study aimed to assess the viability of seeds extracted from ‘baru’ fruits stored for 0, 2, 6 and 10 months at temperatures of 25±3 and 15±3°C. Seedling emergence, emergence speed index, water content and tetrazolium test were assessed after each storage period.
Seeds stored for up to six months maintained their physiological quality and formed vigorous seedlings at both storage temperatures assessed.
