以黄冠梨为试材，研究常温贮藏条件下不同浓度的1-MCP对黄冠梨褐心病的控制效果。结果表明，1-MCP处理能够较好的抑制果实褐心病发病率与发病指数，延迟果实成熟过程，抑制果实的软化。其中，浓度为1.5 μL/L的1-MCP对黄冠梨褐心病控制效果最好，且能较好地保持果实品质。

The control effects on browning heart of Huangguan pears with different concentrations of 1-MCP are studied. The result shows that 1-MCP treatment can better inhibit fruit browning heart disease incidence and disease index， delay fruit ripening， and inhibiting fruit softening. Among them， the concentration of 1.5 UL/L 1-MCP has the best browning heart disease control effect and to better maintain the fruit quality， so it is suitable concentration of 1-MCP treatment for Huangguan Pears.
