Studies on cabbage seed storage
Eduardo Zink; Leocádio de Souza Camargo
SUMMARY
Moisture content, types of containers, method of drying, and fungicide treatment are the factors evaluated in this paper as affecting the germinability of cabbage seed stored under open warehouse conditions for a period of 54 months.
Seed with 5.6 or 5.7 percent moisture content stored well when kept in airtight containers; its germination was still higher than 90 percent sXthe end of the experiment. There was apparently no difference resulting from the method of drying (in a dryer or in the sun), nor was there any from treatment with fungicide on the germinability of the seed. Cabbage seed kept in paper or plastic bags maintained high viability during 12 months regardless of its initial moisture content. After this period its germination decreased slowly and at the 42-month test less than 25 percent of the seed produced normal seedlings. Moisture content of the seed practically reached equilibrium with the relative humidity after 8 months storage.
Seed containing 11.8 percent moisture, kept in airtight containers, decreased rapidly in viability, and after 16 months'storage germination of such seed was nihil.
