Seed vigor is a very complex quantitative trait. Seed vigor is related to many processes, such as seed formation, development and maturity, seed dormancy and germination, seed storage and deterioration, seedling formation and stress tolerance, etc. it determines the comprehensive performance of seed characteristics, such as the activity level and behavior of seeds or seed batches during germination and emergence. It has a great influence on seedling emergence rate and uniformity, seedling growth, crop yield, and quality after sowing, so seed vigor has always been an important research content of seed science. Lifeasible established a seed vigor evaluation platform to measure and evaluate four kinds of indexes, such as seed germination, seedling formation, seed stress tolerance, and seed physiological and biochemical indexes, to provide perfect and reliable testing services for seed researchers.

Sample Requirement
Dry samples, > 10 g Fresh samples, > 15 g *The experimental samples will not be returned, please back them up by yourself. Before sampling, it is necessary to set up the control group and the experimental group, and each group is suggested to repeat more than 3 times. *Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature. *There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information.

*The testing project is constantly updated, please contact our staff by email for more up-to-date and relevant information.
