破碎阶段番茄（Lycopersicon esculentum Mill.，在22 ℃下，在空气中、在氮气（N-2）中的0.5%或1.0%氧气（O-2）或在空气中的80%二氧化碳（CO2）中处理1、3、5或7天，与对照的4天成熟期相比，处理后1天的低O-2处理延迟成熟1-2天;高CO_2处理1天后对果实成熟没有影响，与对照和高CO_2处理相比，低O_2处理增加了乙醇和乙醛的产量。果实在低O_2或高CO_2条件下处理3天或3天以上，表现为表皮损伤和斑点状成熟。发病率随处理时间的延长而增加，但在处理1 d时，可通过降低相对湿度至70%左右来控制发病率。处理1 d果实的硬度、可溶性固形物、可滴定酸、果皮和凝胶的pH值与对照无明显差异。
Breaker stage tomatoes (Lycopersicon esculentum Mill., cultivar 'Bermuda') were treated in air, 0.5% or 1.0% oxygen (O-2) in nitrogen (N-2) or 80% carbon dioxide (CO2) in air for 1, 3, 5 or 7 days at 22 degrees C, A 1 day low O-2 treatment delayed ripening after treatment by 1-2 days compared to a ripening period of 4 days for the control; elevated CO2 for 1 day had no effect on ripening after treatment, Low O-2 increased production of ethanol and acetaldehyde compared to the control and high CO2. Fruit treated for 3 or more days in low O-2 or high CO2 showed skin injury and blotchy ripening. Disease incidence increased with treatment time, but could be controlled in 1 day treatments by reducing relative humidity to about 70%, Firmness, total soluble solids, titratable acidity and pH of pericarp and gel of 1 day treated fruit were not different from the control.
