Abstract
Abstract: Computerized systems for image analysis are alternatives to decrease the subjectivity and speed of assessment of seed physiological potential. The aim of this study was to determine the efficiency of the Seed Vigor Automated Analysis System (Vigor-S) to identify differences in vigor among soybean seed lots compared to results of the Seed Vigor Imaging System - SVIS® and tests recommended for evaluation of soybean seed vigor. Two cultivars were used, BMX Potência RR and 7166 RSF IPRO, each one represented by ten seed lots with similar germination and vigor differences. The seeds were evaluated regarding germination, vigor (tetrazolium, accelerated aging), seedling emergence in the field and SVIS® and Vigor-S analysis, in three experimental periods. Analysis of variance was used on the data in a completely randomized experimental design (laboratory tests) and in randomized blocks (field tests), and the mean values were compared by the Tukey test (p ≤ 0.05). Separation of the seed lots by Vigor-S was consistent with the results obtained in tests recognized as effective in evaluating the physiological potential of soybean seeds, and there was no interference of the different cultivars on the response pattern for vigor. Analysis through Vigor-S proved to be effective in determination of physiological potential and for composition of quality control programs established by soybean seeds production companies.
Highlights
Evaluation of seed physiological potential is a fundamental component of quality control programs conducted by seed production companies
The results of vigor tests are not components of the standards established for the seed trade in Brazil or internationally, they are very important for evaluating the performance of seed lots during storage and after sowing in the field
As seed vigor gathers a set of characteristics, adoption of only one test, whether physiological, biochemical, or of stress resistance, generates incomplete information because a single test is not sufficient to accurately identify the performance potential of seeds exposed to varied environmental conditions (Marcos-Filho, 2015a)
Summary
Evaluation of seed physiological potential is a fundamental component of quality control programs conducted by seed production companies. Germination, tetrazolium-vigor, traditional accelerated aging (TAA 48 h) and accelerated aging with saturated NaCl solution (SSAA 72 h), seedling emergence percentage and speed in 10 soybean seed lots, cultivar BMX Potência RR (Cultivar 1).
