The objective of the research was to study the postharvest response of avocado fruits cv. Hass coming from avocado trees with different rootstock to the effect of different doses of 1-methylcyclopropene. Avocado fruits cv. Hass from 8-year-old trees whose rootstocks, clonally propagated; were Dusa and Zutano. 'Hass' fruits, before being stored at 6.5 ± 1.3 ºC for 40 days, were treated with 0, 1 and 2 ppm of 1 methylcyclopropene (1 MCP). After storage period was completed, avocado fruits showed differences in weight loss due to the interaction between doses of 1 MCP and rootstock, finding that fruits taken from trees with Zutano rootstock lost more weight, a result that was more appreciated when fruits did not receive 1 MCP. Likewise, these fruits showed a lower L* color index compared to those fruits coming from trees with Dusa rootstock. On the other hand, fruits treated with 1 and 2 ppm of 1 MCP presented slightly higher C*, hº and firmness values. The evaluation of the fruits 9 days after removal from storage showed that those treated with 1 and 2 ppm of 1 MCP had less accumulation of dry matter and oil and better pulp firmness. This response was more noticeable in fruits treated with 2 ppm of 1 MCP. Moreover, the respiratory rate of the fruits evaluated after leaving storage decreased, being noticeable in those that did not receive 1 MCP while those treated with 1 and 2 ppm of 1 MCP increased their respiratory rate on the fourth and fifth day respectively. Therefore, respiratory rate levels decreased in all treatments.
