摘要
O objetivo do trabalho foi comparar a efici那ncia de testes para determina o do potencial fisiol車gico de lotes de sementes de ab車bora. Avaliaram-se seis lotes de sementes, submetidos a testes de germina o e vigor (primeira contagem; velocidade de germina o;germina o 角 temperatura sub車tima; envelhecimento acelerado; emerg那ncia de plantulas; crescimento e fitomassa seca de plantulas (rad赤cula, hipoc車tilo e total) e plantas (raiz, caule, raiz e caule, folhas e total). Utilizou-se o delineamento inteiramente casualizado, com quatro repeti es; as m谷dias foram comparadas pelo teste de Tukey (p ≒ 0,05). Realizou-se tamb谷m o teste de correla o de Pearson. Os testes de primeira contagem, velocidade de germina o, envelhecimento acelerado, fitomassa seca de raiz e caule e de folhas de plantas,podem ser utilizados para avaliar potencial fisiol車gico de sementes de ab車bora. 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.
