This invention discloses a
dry heat treatment method for tomato seeds to enhance seed vigor and extend storage life, relating to the field of
tomato seed storage technology. The method includes: selecting mature, plump, and undamaged commercial tomato seeds with consistent maturity and maintaining appropriate
moisture content; placing the pre-treated seeds in a single layer on a tray and placing it in a
dry heat treatment device, performing
dry heat treatment sequentially according to a preset program; comparing the
germination indicators of dry heat-treated and untreated seeds to determine the effect of the dry heat treatment; and sealing and storing tomato seeds with qualified
germination rates. This invention, through precisely controlled stepwise heating and high-temperature constant-temperature sterilization, effectively activates the seed's internal
repair enzyme system while inhibiting metabolic processes that lead to seed deterioration, avoiding physical or physiological damage to the seeds caused by high-
temperature treatment, and effectively preventing seed coat
cracking,
radicle burn, or excessive
dehydration.
