Abstract:
Sapota is a climacteric fruit so it necessitates careful postharvest handling to reduce losses, future hindering the storage and distribution of fruits. Postharvest life of fruits depends on harvesting time, chemical applications and storage conditions. With a view to the perishable nature of sapota fruits and for extending the postharvest life, the experiment was laid out at Centre of Excellence on Post Harvest Technology, ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat, India during the year 2020-21. The fruits treated with different concentration of 1-MCP and stored under ambient temperature and low temperature (12.0 ± 0.5 ℃) viz., T₁ (1-MCP @ 0 nL L^-1 + ambient temperature), T₂ (1-MCP @ 0 nL L^-1 + low temperature), T₃ (1-MCP @ 20 nL L^-1 + ambient temperature), T₄ (1-MCP @ 20 nL L^-1 + low temperature), T₅ (1-MCP @ 40 nL L^-1 + ambient temperature), T₆ (1-MCP @ 40 nL L^-1 + low temperature), T₇ (1-MCP @ 60 nL L^-1 + ambient temperature), T₈ (1-MCP @ 60 nL L^-1 + low temperature), T₉ (1-MCP @ 80 nL L^-1 + ambient temperature), T₁₀ (1-MCP @ 80 nL L^-1 + low temperature), T₁₁ (1-MCP @ 100 nL L^-1 + ambient temperature) and T₁₂ (1-MCP @ 100 nL L^-1 + low temperature). The physical and physiological parameters of sapota fruit were assessed at five days interval. The result revealed that the sapota fruits fumigated with 1-MCP @ 100 nL L^-1 and stored under low temperature (12.0 ± 0.5 ℃) had recorded maximum marketable fruits and minimum PLW, spoiled fruit, ethylene production and respiratory activity with more firm fruits at 20^th day of storage. The highest shelf life (22.39 days) was noted in fruits which treated with 1-MCP at 100 nL L^-1 and stored at low temperature 12.0 ± 0.5 ℃.
