EXPLANATION
Rose and Carnation Production Technology
- Long-term Dry Storage of Carnation (Dianthus caryophyllus):
- Carnation cut flower stems harvested at the "paint-brush" or tight-bud stage can be stored dry for extended periods of 16 to 24 weeks.
- Temperature Requirement: Kept inside moisture-proof polyethylene film liners in corrugated fibreboard boxes maintained at $0^{\circ}\text{C}$ to $1^{\circ}\text{C}$ ($32^{\circ}\text{F} - 34^{\circ}\text{F}$) with $90-95\%$ relative humidity.
- Higher temperatures (above $2-4^{\circ}\text{C}$) accelerate carbohydrate respiration and ethylene production, drastically shortening storage life.
- Correct Option: Option 4 (0-1°C).
