ANÁLISE AUTOMATIZADA DO VIGOR DE SEMENTES DE ALGODÃO POR MEIO DE IMAGENS DE PLÂNTULAS

Abstract

The use of seeds with high physiological potential is essential to provide satisfactory establishment of the culture. The objective of the present study was to develop a methodology for automated analysis of cotton seed vigor through the use of software. The experiments were conducted at Instituto Federal Goiano, Campus Urutaí. Five batches of seeds of Gossypium hirsutum were used, with differences in the physiological potential and submitted to the tests: water content (TA), first germination count (PC), germination (G), seedling length (CP), accelerated aging ( EA), field emergence (EC), emergence speed index (IVE) and digital image evaluation (ADI). The best physiological potential was observed in lot 4 as it presented the best rates of PC, G, EA. For CP, lot 2 had the highest average. For ADI, the best lots were 3 and 4. Lot 1 had the lowest averages for PC, G and CP. For EA, the lowest average was lot 5. The ImageJ® software can be used as an auxiliary tool for traditional analyzes of germination and first count for cotton seedlings, as it presents a moderate correlation.
