STUDIES ON THE RAPID METHODS FOR EVALUATING SEED VIGOR OF SWEET CORN Guangwu Zhao1,*, Linlin Yang2, Jianhua Wang3, Zhujun Zhu1 1 School of Agriculture and Food Science, Zhejiang Forestry College, Lin’an, China, 311300 2 College of Foreign Languages, Wenzhou University, Wenzhou, China, 325027 3 Department of Seed Science and Technology, China Agricultural University, Beijing, China, does not test seed vigor. Seed vigor may decrease even as germination rate remains constant. To maintain high vigor and germination, store seeds at low, constant temperatures with very low humidity. Some species or varieties simply don’t have the same storage life as others, which is why regular germination testing is so important.

eed vigor testing provides valuable information for assessing seed lot quality. However, most vigor tests have not experienced widespread use because of their subjectivity, high cost and variability in test results from laboratory to laboratory. This report presents a system for automated seed vigor assessment that is objective, economical and Abstract. The standard seed germination test often overestimates actual field emergence. Several physiological and biochemical tests have been developed for evaluating seed vigor in various crops, but the relationship between vigor testing and field performance has not been studied extensively in grasses.

Beginning 24 hr after seeding, peanut was counted as germinated when radicles were greater than 5 mm long, with removal each day.

    eed vigor testing provides valuable information for assessing seed lot quality. However, most vigor tests have not experienced widespread use because of their subjectivity, high cost and variability in test results from laboratory to laboratory. This report presents a system for automated seed vigor assessment that is objective, economical and Although vigor testing is not required by law for labeling of seed, many seed producers use vigor tests as a quality control to ensure that the seed produced is of high quality. Many factors, such as maturity level at harvest, age of the seed, mechanical injuries, disease infection, and …

    Seed Vigor Testing. The basic objective of seed vigor testing is to provide a precise identification of important differences in physiological potential among seed lots of commercial value, mostly those of similar germination percentage, aiming to identify lots of higher probability to perform well after sowing and/or during storage.

    The assessment of seed vigor has many important implications to the seed industry as a basic monitoring of seed physiological potential during different phases of seed production and a support for strategic decisions regarding the selection of high quality seedlots to meet the consumer demand. Seed vigor testing: an overview of the past Seed vigor tests do not replace with the germination test, but they are its supplementary. Each factor that causes loss of germination formerly it reduces seed vigor, because vigor is more sensitive in comparison with germination. Relations between seed vigor, laboratory germination, field emergence and yield have been the subjects of numerous
