Influence of biostimulants on the physiological quality of pepper and cucumber seeds
This study aimed to verify the influence of biostimulants in the germination, vigor and transplants development of pepper and cucumber. In the survey, pepper and cucumber seeds were used and treated with Radifarm® (RF) and Stimulate® (ST), diluted in 100 mL of distilled water in doses following 24 h of seed soaking: 0, 1, 5, and 15 mL for RF, and 0, 5, 15, and 30 mL for ST. Evaluations of seed moisture content, germination and vigor such as electrical conductivity, and germination speed index were made. The experimental design was completely randomized with four replicates per treatment and the averages compared by the Tukey test (5%). From the results, it may be concluded that treatments with Radifarm® and Stimulate® influenced the germination, seed vigor and transplant development of pepper and cucumber. Seed germination of pepper and cucumber was impaired by seed treatment with Radifarm® and Stimulate®. Both biostimulants increased cell leached seeds, in both pepper and cucumber, by the electrical conductivity test and reduced the speed of germination of pepper and cucumber transplants. While compromising seed quality, the Radifarm® may not be suitable for use as seed treatment.
