Asexual, sexual reproduction and seed vigor of Caracolí Anacaridum excelsum (Bertero ex Kunth) Skeels in the Sucre department

Abstract

The dry tropical forest in Colombia is in constant decline and deforestation of their coverage, Anacardium excelsum is a representative in this forest, but is almost threatened at the nationwide. Given this and its importance as a timber tree the objective of the research was to find the best form of reproduction, sexual or asexual, and determine the vigor and the best pre-germinative treatment to break dormancy of seeds. Seven different pre-germinative treatments and three with hormone solution for rooting cuttings were performed. Scarification with a scalpel and immersion in HCl for 5 minutes had a higher percentage of germination, most plants germinated before 4 days after being planted, and showed a growth rate between 3 and 4 cm per day in the first week. With respect to the asexual reproduction, in no of the stakes was obtained formation of roots and buds. Sexual reproduction proved to be the best method, and the pre-germinative scarification treatment with scalpel was the one with the highest percentage of germination.
