Module 12 : Seed maturity and harvest
Training, self-paced, seed production, health, quality
Welcome to this new training module, “Seed maturity and harvest” !
Hello ! My name is Steven Groot.
I’m a seed biologist and have worked for almost 40 years at Wageningen University & Research on seed biology and seed technology. At present I provide training and consultancy on these topics in the frame of the International Seed Academy. I’m also vice-chair if the Seed Storage Committee from the International Seed Testing Association. Today, we are going to talk to you about the physiological processes underlying seed maturity. These need to be considered to understand when and how to harvest seed crops.
Understand when and how to harvest seed crops : why it is important ?
Harvesting is a key moment in seed production, especially for seed quality. If seeds aren’t harvested at the right time, followed by adequate drying, they may lose some of their vigour and storage potential.
After completing this module, you will be able to
- describe the physiological processes underlying seed maturity ;
- decide on an adequate harvest method, based on whether the seed of a given crop species matures gradually or all at once, and whether it sheds seeds at maturity ;
- provide adequate harvesting and drying conditions for gradually maturing and seed shedding seed crops.
