Seed storage activities include:
Show answer Hide answer
Answer: D. All of the above
Explanation
Well-ventilated seed storage facilities prevent the accumulation of damaging humidity and respiratory heat. Eliminating dampness is critical to prevent premature seed germination and fungal growth during storage. Protecting stored seeds from rodents and insects ensures high viability before planting seasons. Seed storage is a vital agricultural practice aimed at preserving genetic resources and planting stock. High moisture content combined with warm temperatures drastically reduces seed viability over time. Pest infestations can destroy large quantities of stored grain and tree seeds within weeks.
Agricultural seed banks maintain strict climate controls to preserve rare crop varieties for decades. Farmers store harvested crop seeds in sealed, pest-proof containers to guarantee next season's harvest. Forestry nurseries follow rigorous storage protocols to maintain high germination rates for tree seeds. Option A is partial because ventilation alone cannot prevent insect damage or dampness. Option B is incomplete because dry seeds remain vulnerable to rodent and insect destruction. Option C is wrong because pest protection is useless if excessive dampness destroys seed embryos.
