Abstract

Abstract. Fatonah K, Suliansyah I, Rozen N. 2017. Electrical conductivity for seed vigor test in sorghum (Sorghum bicolor). Cell Biol Dev 1: 6-12. The objectives of this study were to obtain electrical conductivity test method for seed vigor test in sorghum, to recognize relationship between electrical conductivity test and potassium leakage, and to recognize relationship between electrical conductivity test and other variable on seed vigor. This study have two step experiments. The objective of Experiment I was to determine accurate combinations of water volume and amount seed of the electrical conductivity test for seed vigor test in sorghum. Completely Randomized Design of 15 seed lots with 3 replications were used to determine electrical conductivity method with different vigor. Experiment II were to test electrical conductivity method of 21 seed lots of sorghum without accelerated aging test and 21 seed lots of sorghum were given accelerated aging test. Completely Randomized Design of 21 seed lots with 3 replications were used in Experiment II. The variable were observed : standard germination, field emergence, speed of germination, first count, conductivity, potassium leakage and eight combination conductivity method of water volume (50, 100, 150 and 200 ml) and amount of seed sorghum (50 and 75 seed count). The result of this experiments showed that electrical conductivity test method with 150 ml water volume and 75 seed count was accurate and suitable for sorghum seed vigor test; electrical conductivity test showed positive correlation with potassium leakage; and electrical conductivity test can be used for seed vigor test in sorghum and provided the potential of physiological seed were shown through : standard germination test, field emergence test, first count test and speed of germination with negative correlation.

Rapid and Nondestructive Measurement of Rice Seed Vitality of Different Years Using Near-Infrared Hyperspectral Imaging

“…Many research works have been conducted to construct potential rapid and non-destructive methods to measure seed vigor. Four non-destructive approaches with different techniques or principles, i.e., nuclear magnetic resonance spectroscopy [7], X-ray [8,9], laser speckle technique [10] and the measuring technology of seed conductivity [11] were investigated, however, they have not been widely used because of the low efficiency and complicated operation. Fortunately, recent studies show that molecular spectroscopic techniques, such as point-based and image-based hyperspectral techniques, have great potentials in the detection of seed ingredients with the advantages of high detection speed, non-destructive nature and low cost [12].…”

“…A decrease in germination and seed growth capacity follows the electrical conductivity increment, as has been proven in R. apiulata propagules (Rohandi and Widyani, 2010), sorghum seeds (Fatonah and Rozen 2017), soybean seeds (Noviana et al 2017) and A. mangium (Pujiastuti and Sudrajat 2017). In contrast to this study, the electrical conductivity increment was not followed by a decrease in seed germination or vice versa.…”

Changes on Sugar and Starch Contents during Seed Development of Synergistic Sweet Corn and Implication on Seed Quality

“…From our study, it is interesting to note that the EC value is strongly associated with seed quality, suggesting that the EC value is an efficient indicator for seed vigor of sweet corn. is parameter was also suitable for sweet corn [36,37] and other crops including pea [38], sorghum [39], and safflower [40]. However, Zhao et al [36] reported that the EC test was only reliable to estimate the seed vigor of sweet corn with the se gene.…”
