Luminosity and temperature on pecan seed germination
Abstract
The objective of present work was to evaluate the effect of luminosity and temperature on Carya illinoinensis germination seeds. In order to standardize imbibition process, seeds were previously submitted to scarification process. The experimental design was completely randomized, arranged with a 3x4 factorial scheme, in which were tested three luminosity regimes (absence of light, continuous light and alternating light of 12 hours) and four temperature conditions (20°C, 25°C, 30°C and alternating 12 hours at 15°C and 12 hours at 25°C), with five replicates. Variables evaluated were emission of radicle (%),seed germination rate (SGR), germination time (GT), normal seedlings (%), abnormal seedlings (%), hard seeds (%), dead seeds (%) root and shoot length(mm/seedling). Combination of absence of light and high temperature favors the emission of the radicle, SGR and reduces GT, as well as provides greater root and shoot length. However, the temperature of 25°C together with absence of light obtained superior results for the formation of normal seedlings, being the most suitable combination for the germination of C. illinoinensis seeds.
