Abstract

Abstract: Melon is a vegetable crop of food and nutritional importance whose cultivation is growing worldwide. In this sense, investments in technologies are necessary, especially regarding the quality of seeds used in the establishment of new areas. This study aimed to verify the effectiveness of the Automated Seed Vigor Analysis System (Vigor-S) in the evaluation of the physiological potential of melon seeds. Eight seed lots (four lots of the hybrid Supreme and four of the hybrid Premier) were used. The physiological potential of the seeds was evaluated through tests indicated for analyzing the quality of melon seeds associated with the image analysis by using the software Vigor-S, which included the analysis of seedlings from the germination test and accelerated aging in saturated NaCl solution. The experiment was conducted in a completely randomized design, with five replications. The results indicated the effectiveness of Vigor-S, especially when it was used associated with the accelerated aging test in saturated NaCl solution, with results similar to those obtained in traditional vigor tests. Thus, the Automated Seed Vigor Analysis System (Vigor-S) was effective in evaluating the physiological potential of melon seeds.

Highlights

Melon (Cucumis melo L.) is a vegetable crop of food and nutritional importance whose cultivation is growing worldwide (Medeiros et al, 2015)
The need for complementary information provided by the germination test and the possibility of using high-precision computational resources to evaluate the physiological potential is essential to the quality control programs of seed-producing companies (Medeiros et al, 2020)
The initial water content of the seeds, as well as after accelerated aging with saturated NaCl solution and after the period of controlled deterioration, was similar between the hybrids Premier and Supreme, with an increase in seeds submitted to aging and deterioration processes (Table 1)

Summary

Introduction

Melon (Cucumis melo L.) is a vegetable crop of food and nutritional importance whose cultivation is growing worldwide (Medeiros et al, 2015). The use of seeds with high physiological potential is essential to obtain high-quality seedlings (Silva and Cícero, 2014), ensuring the establishment of adequate populations in the field. The physiological potential of a seed lot is officially evaluated for commercialization through the germination test. It evaluates only seed viability, providing information regarding the maximum percentage of germination (Leite et al, 2019). The need for complementary information provided by the germination test and the possibility of using high-precision computational resources to evaluate the physiological potential is essential to the quality control programs of seed-producing companies (Medeiros et al, 2020)
