Desiccation effects on germination and vigor of King palm seeds
Provedor de dados: 75
Autores: Martins,Cibele C.; Bovi,Marilene L. A.; Nakagawa,João.
The desiccation tolerance of Archontophoenix alexandrae (Wendl. &amp;amp; Drude) seeds was determined and the most sensitive vigor test for assessing seed deterioration of this species was identified. Mature fruits were harvested in the palm collection of the Instituto Agronomico in Campinas, Brazil. Depulped fruits were transported in impermeable packages to the Faculdade de Agronomia in Botucatu, where the seeds were dried. As the seed moisture decreased, germination, seedling length, electrical conductivity and moisture were measured. The seeds of A. alexandrae are recalcitrant, with high germination percentage (over 67%) when undried (47% seed moisture). Lowering seed moisture below 31.5% reduced the germination rate significantly (&lt;52.5%). Total...
