Germination, survival, and growth of Cordia dodecandra A.DC. under Field Conditions

Resumen

Objective: Cordia dodecandra A.DC., an endemic species of the Yucatán Peninsula, Mexico, is valued for its fruit and timber production in the market. This study evaluated seedling emergence and growth from seeds directly sown in the field using pregerminative treatments.
Design/methodology/approach: The research was conducted in the town of Castamay, Campeche. The land was prepared using agricultural machinery. Scarification treatments consisted of T1: 10%, T2: 20%, and T3: 50% hydrogen peroxide in purified water, as well as an untreated control, using seeds harvested in the same year.

Results: The highest number of seedlings emerged in the control treatment. Height and diameter growth varied across measurement periods, and both temperature and ambient humidity significantly affected these variables.

Findings/conclusions: The use of C. dodecandra seeds for reforestation in deforested areas is viable, with up to 80% success. Scarification is not required when seeds are sown in the same year they are harvested. Seedlings of C. dodecandra grown from directly sown seeds in the field exhibit steady growth, which is influenced by temperature and humidity conditions.
