Dormancy breakage and germination in Sapindus saponaria L. seeds as a function of temperature and germination substrate ; Superação de dormência e germinação em sementes de Sapindus saponaria L. em função do substrato da temperatura e germinação

The objective of this study was to evaluate different pre-germination treatments, histochemical characteristics and physiological performance of Sapindus saponaria L. seeds as a function of temperature and the germination substrate. The S. saponaria seeds were collected in the municipality of Rio Verde, GO, and analysed through the execution of 2 tests (dormancy breakage and germination tests). Test 1 consisted of 10 treatments for overcoming dormancy, whereas test 2 consisted of a 35-day evaluation of germination on several substrates (paper and sand) under the following 4 temperature conditi...
