Abstract

This work aimed to determine the efficiency of different tests to access the physiological potential of squash seed lots. Six seed lots were submitted to germination and vigor tests (germination first count; speed of germination; cool germination; accelerated aging; seedling emergence; seedlings growth and dry biomass (root, hypocotyl and total) and plants (root, stem and total length, root, stem, root plus stem, leaves and total). A completely randomized design was used with four replicates. The averages were compared by the Tukey test (p ≤ 0.05). Pearson’s correlation test was also performed. The germination first count, speed of germination, accelerated aging, root plus stem and leaves dry biomass from plants evaluated in the 21st day after sowing can be used to determine the physiological potential of squash seeds.

No Mestrado realizou trabalhos visando a Avaliação do Potencial Fisiológico e da Qualidade Sanitária de Sementes de Hortaliças, com dissertação no referido assunto. O trabalho de Tese contemplou a validação de um modelo teórico de extração de água do solo por raízes e propôs-se um novo modelo para a extração de água por raízes baseado nos aspectos que regem o movimento da água no solo e a interrelação do sistema solo-planta-atmosfera. Atualmente, é Bolsista FAPESP de Pós-Doutorado em Agronomia no Departamento de Ciências Exatas da Escola Superior de Agricultura "Luiz de Queiroz" - USP. Currículo Lattes
