GerminaQuant: a new tool for germination measurements

Abstract: -The seed technologies related with germination and seed research has provided unprecedented opportunities for the biologic research community. Researchers require such information to rapidly determine the speed of seedling emergence. However, an immense amount of data must be analyzed to achieve this goal. In this paper, we introduce a computer software designed for broad use to facilitate the understanding of germination processes and their analysis. GerminaQuant 1.0 was written in the C++ programming langua… Show more

“…Processing data and statistics. After the evaluation, we calculated, using the GerminaQuant software (Marques et al 2015), the germination percentage (G = %) and the mean germination rate: MGR = 1/t, where t = ∑ni.ti/∑ni, where ti is the period between the beginning of the experiment and the nth observation (days) and ni is the number of seeds germinated in the time i (number corresponding to the nth observation) (Labouriau 1983). Before statistical analysis, the germinability data obtained underwent an angular transformation (arc sine √%).…”

“…Ao termino do experimento foram calculados, no software GerminaQuant 1.0 (Marques et al 2015), a germinabilidade (G = %), o tempo médio de germinação onde ti é o período desde o início do experimento até a enésima observação (dias) e ni é o número de sementes germinadas no tempo i (não o número acumulado, mas o número correspondente a enésima observação)], a velocidade média de germinação (VMG = 1/ t) e o índice de sincronização, onde fi é a frequência relativa da germinação (i.e., a proporção de sementes germinadas em intervalo)], bem como a frequência relativa de germinação [f i = n i / ∑ n i ] de acordo com Ranal e Santana (2006).…”
