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

Abstract

Cordia dodecandra A.DC. is an endemic species of the Yucatan Peninsula, of great importance for the production of fruits, and for its wood, which is in high demand in the market. The objective of this work was to know the behavior of the emergence and growth of seedlings obtained from seeds sown directly in the field with pregermination treatments. The research was carried out in the town of Castamay, Campeche, the land was prepared with agricultural machinery. The scarification treatments were T1: 10%, T2: 20% and T3: 50% of hydrogen peroxide in purified water and a control without treatment, using seeds from the same year. The results showed that the highest number of seedlings was obtained in the control, and that the growth in height and diameter showed that the increase is different between measurement periods, and that the temperature and environmental humidity do affect these variables.
