EVALUATION OF TWO METHODS OF GERMPLASM COLLECTION IN MEXICO SOUTHEAST

The implementation of good farming practices in seed collecting is fundamental key to guarantee the physiological and genetic quality of forest seeds. The objective of this work was to evaluate the implementation of two methods to collect seedsfrom Cedrelaodorata L.toguarantee seeds of high physiologicalquality. Seeds from 40 superior phenotypically trees of Cedrelaodorata L. in Yucatan Mexico peninsula region were collected from March to May 2019.The collect methods applied in this research werethe traditionalcollectand the climb trees. The physiological quality of seeds wasevaluated by germination and tetrazolium test. The laboratory analysis confirmed 88% of seeds pure with 94% of germination in climbing trees method, in contrast in the traditional method showed 66% of seeds pure with 72% of germination. The results by conventional germination it was not showed significative statistical differences. These results are part of novel contributions in collectmethodology using tools to climb on trees which to be complement of superior phenotypically trees selection, contribute comprehensively to obtain physiological and genetic quality forest seeds
