Abstract ▼

The availability of fresh water is one of the biggest problems that could be exacerbated by climate change. Agriculture uses more than 70% of the fresh water in the world. Water tables are dropping rapidly in many parts of the world and will continue to shrink as more land is converted to grow food

The availability of fresh water is one of the biggest problems that could be exacerbated by climate change. Agriculture uses more than 70% of the fresh water in the world. Water tables are dropping rapidly in many parts of the world and will continue to shrink as more land is converted to grow food and fuel crops. One of the biggest challenges for agricultural biotechnology is to develop drought-tolerant crops that can thrive with less water without impeding yield. It has been well-known that 1-MCP (1-methylcyclopropene) is one of the most effective ethylene inhibitor to delay fruits' self-aging. The science behind an 1-MCP was originally discovered by Prof.Sisler at North Carolina State, a leading American university for agricultural studies, who studied the natural ripening process of apples in the mid-1990s. Now, 1-MCP is known to be the most effective material to prevent ethylene to trigger ripening process of picked fruits and vegetables. But 1-MCP exists in gas stage at the room temperature and is not suitable for using in the open field as a ethylene antagonist.
It was Rohm and Haas who firstly developed 1-MCP storing method and they used alpha-cyclodextrine to absorb each 1-MCP molecule separately to prevent polymerization and it was commercialized as name of SmartFresh. and That Rohm and Haas now are tried to develop new Ethylene antagonist with Syngenta and the project name INVINSA which can be used in the field for crop stress protection.
We studied and developed 1-MCP generationg device after Rohm and Haas and also stuied ethylene antagonist which is suitable for open field to lessen the crop stress.
The key idea behind this research and development is that if it has more molecular weight, it can exists in the liquid state and be suitable for the open field. That's because we synthesized LCCP(longer chained cyclopropenes) and tested the efficacy. As far as we found out, our technology works for ethylene antagonist and 1-alkylcyclopropene derivatives we develop can be used for etylene antagonist
