Atributos físicos de sementes de soja (glycine max) armazenadas por meio do teste de tetrazólio

Abstract

Brazil has stood out in the world as a great producer of soy, and the Piauían cerrado shows itself as a great agricultural potential in this scenario. In order to keep up with increasing agricultural potential, it is necessary to develop new technologies in order to provide more agile decision-making, making it necessary to collect accurate information for agribusiness, and in this context, the tretazolium test has been significant for the sector, presenting fast and safe responses to care in grain production and seed treatment. The objective of this study was to analyze the results of vigor, viability, mechanical damage, moisture damage and bedbug damage during tetrazolium tests during the storage period of soybean varieties FTR 2182 IPRO, FTR 4182 IPRO and FTR 4288 IPRO samples collected in a specific place for storage in silo, and big beg of 1000 kg; the samples were collected at similar time intervals. The methodology of collection applied was the same in all analyzes, respecting the type of storage and the cycle of time applied. Considering the results found in the three varieties, it was observed that the two storage modalities did not present significant losses, causing the seeds to respond well to the storage period in a controlled temperature environment, being the vigor and viability as determinants of grain quality, both methods presented satisfactory results at the end of storage for the conservation of seed quality.
