Physiological quality of rambutan seeds (Nephelium lappaceum L.) subjected to electrical conductivity

Abstract

Electrical conductivity testing is a quick and effective technique for assessing seed quality and making quick decisions about seed management. This study aimed to evaluate the physiological quality of rambutan seeds using the electrical conductivity method. The rambutan seeds were collected in four microregions of Brazil and submitted to different procedures, such as water content, germination percentage (PG), emergence speed index (IVG), mean germination time (TMG) and electrical conductivity test (CE). The results showed significant differences between the lots tested for the variables PG, IVG, TMG and EC, with lot 4 showing the best physiological quality and the lowest EC value. In conclusion, the electrical conductivity test can be an efficient technique to evaluate the vigor of rambutan seeds and help in the process of producing quality seedlings.
