The zamota (Coursetia glandulosa A. Gray) is a non-timber plant, which can measure up to approximately 3 meters, it is important for the agricultural sector in the state of Sonora, currently it is presenting serious problems derived from the effects negative produced by climate change. The objective of this work was to determine the effect of global warming on the production of Zamota seeds in their natural habitat. In seed production, there were significant differences (P < 0.05), according to the collection time and extracts evaluated (plant height: 1.5 to 1.80; 1.90 to 2.20 m). A total seed production was obtained in 2019 of 14.87 K of seeds between both extracts, while the production for 2020 was 6.34 K of collected seeds. Therefore, the seed production in 2019 was 2.34 times higher than that obtained in 2020. In 2019, the E2 presented an average seed production per plant of 0.598 g with a standard deviation of 0.052 and for the E1 it was of 0.393 g of seeds with a standard deviation of 0.022, while for 2020, the E2 presented an average of 0.253 g and the E1 was 0.169 g. The maximum, minimum temperatures and relative humidity evaluated in both years, their behavior was similar except the rainfall was lower in 2020, especially in the most critical time of the year, which is summer.
