呼吸速率，乙烯产生和软化的未处理和处理（丙烯或乙烯）鳄梨果实（波斯美洲磨坊，品种哈斯）的生长和成熟过程中使用的果实收获每月从8月至7月。未处理的未成熟果实在8月收获表现出跃变型，产生乙烯和软化后18，21和18.5天，分别。从收获后第1天开始处理这些未成熟果实1至3天，在处理期间刺激呼吸，但在处理终止后1天内呼吸速率降低至未处理果实的水平，随后它们抑制了未处理果实的响应。未成熟果实的乙烯释放量不受处理的诱导，而成熟果实的乙烯释放量受处理的诱导。跃变型峰值速率和乙烯释放峰值速率随果实成熟而增大。随着季节的推移，进入更年期高峰的天数和软化的天数减少。乙烯或丙烯处理的果实有一个逐步缩短的时间跃变和软化，因为它们成熟相比，未经处理的水果。
The respiratory rate, ethylene production and softening of untreated and treated (propylene or ethylene) avocado fruit (Persea americana Mill, cv Hass) were determined during growth and maturation using fruit harvested monthly from August to July. Untreated immature fruit harvested in August exhibited a climacteric, produced ethylene and softened after 18, 21 and 18.5 days, respectively. Treatment of these immature fruit for 1 to 3 days beginning 1 day after harvest stimulated respiration during the treatment, but the respiratory rate decreased to the level of the untreated fruit within 1 day after the treatment was terminated and they subsequently paralleled the response of the untreated fruit. Ethylene production was not induced by the treatment in immature fruit, but was in mature fruit. The climacteric peak rate and the peak rate of ethylene production increased as the fruit matured. The days to the climacteric peak and days to soften decreased as the season progressed. The ethylene or propylene treated fruit had a progressively shorter time to the climacteric and to softening as they matured compared to the untreated fruit.
