Abstract
Onion seeds (cultivar Caledon Globe), and soil into which the seedlings were
planted, were treated with various adjuvants including fungicides, a seed
disinfectant and a soil sterilant, as well as soil-applied growth stimulants to
determine the effect of these on germination of seed, the growth of plants and
the storage life of onions obtained. Three sets of germination trials were
undertaken in petri dishes, and sets of seed was also sown in deep seed trays.
A trial planting was made and the crop graded and stored. Seed was also sown
in pots in soil obtained from a commercial undertaking where poor
germination had been obtained. A portion of this soil was pasteurised and a
portion inoculated with Fusarium spp. Growth of these seedlings was then
followed by re-sowing in the same pots using seed of additional cultivars.
