Effects Of 1-MCP On Postharvest Physiology Of Fruits, Vegetables And Flowers
- Mar 06, 2019 -

(1) The influence on ethylene production. Ethylene can lead to the senescence and physiological imbalance of Postharvest Horticultural crops. 1-MCP inhibits ethylene

Normal binding with its receptors blocked ethylene feedback-regulated biosynthesis.

(2) The effect on respiration. 1-MCP can inhibit the respiration of plant tissues or organs [9]. It not only delays high breathing

The time of peak appearing and the peak of respiratory rate decreased.

(3) The effect on ripening and softening of fruits and vegetables. Postharvest climacteric fruits and vegetables have a Post-ripening process, accompanied by the emergence of softening of fruits and vegetables.

After 1-MCP treatment, exogenous ethylene treatment could not accelerate the softening of fruits and vegetables, which may be due to the lack of sufficient new ethylene in tissues.

Receptor-induced. But if enough time and sufficient number of ethylene binding sites can be synthesized, exogenous ethylene can induce post-harvest fruits and vegetables.

Ripe. This indicates that the inhibitory effect of 1-MCP is only related to the early ripening stage of fruits and vegetables, and the triggering of softening of fruits and vegetables is an irreversible process.
