摘要

Fast and reliable results from seed quality tests are essential for producers. The Seed Vigour Imaging System (SVIS) was developed to improve assessment of seed quality. This study had the objective of identifying the optimum paper towel moisture contents and temperatures for maize and soyabean seed germination during a three-day test period. Seeds were planted on paper towels with seven different moisture contents for maize and eight for soyabean. Three different temperatures (24, 25 and 26 degrees C) were used for germination of the two crops. Decreased speed of growth and overall vigour indices were observed when the moisture content of the paper towels had less than 96% saturation in maize and 79% saturation in soyabean. When the germinator temperature varied 1 degrees C less than 25 degrees C, no difference was detected in the SVIS indices. However, a difference of 1 degrees C more than 25 degrees C caused a significant increase in seedling growth. These results demonstrate the importance of monitoring paper towel moisture contents used for the SVIS test, particularly for maize seeds, and show that moisture and temperature variables must be carefully controlled during standard germination and vigour tests to assure standardization of reported results..
