Study Notes
- Pollination is a crucial process in seed production, involving the transfer of pollen from the male anther to the female stigma
- Seed producers can aid insect pollination by attracting bees and other insects to crops through methods like colony placement and wild bee cultivation
- Seed inspections are necessary to verify seed sources and check for unwanted plant types and weeds
- Rouging is the process of removing unwanted plant types and weeds from the seed crop
- Disease and insect control are essential to maintain seed quality
- Seed harvesting should be carried out at optimal moisture levels and weather conditions
- Seeds should be dried after harvest to safe moisture content levels for preservation
- Seeds are stored from maturity until planting, ideally in cool, dry, clean facilities with proper labeling to prevent mechanical mixture
- Seeds can be packaged in materials like cotton, jute, and paper but should be protected against high relative humidity for long-term storage.
