Question

Orthodox seeds can be preserved for long periods at a temperature of

• A. -196${}^o$C
• B. -10 to -20${}^o$C
• C. 0 to - 4${}^o$C
• D. 10 to 15${}^o$C

Answer 1

The correct option is B -10 to -20${}^o$C

Orthodox seeds can be desiccated and then stored. Storage life is increased by low temperature. These should maintain high vigor and viability at least from harvest until the next growing season or for many decades at - 18${}^0$C
