Qualitative and Quantitative Evaluation Protocol of Baccharis Seed Germination

Abstract

Baccharis trimera (Less.) DC (E1) and Baccharis crispa Spreng. (E2) possess potential antimicrobial and anti-inflammatory properties. Qualitative and quantitative information on seed germination on these species is scarce. The objective of this investigation was to establish a protocol for evaluating seed germination of E1 and E2 and to analice the scoring and curve fitting by the Germinator package, for different periods of germination were between 0.93 and 0.99. Both species showed differences in germinability and mean germination time, 27 days for E1 and 20 days for E2. The germination dispersion showed that E1 germination was homogeneous, with differences in growth pattern, whereas the results on germination of E2. The mean speed of germination determined with the experimental data was close to the values obtained by the Germinator package, with a maximum germination of more than 34%, proving that the software was efficient for evaluating germination.

Optimización del “Germinator” como complemento de análisis de calidad germinativa de semillas de arroz (Oryza sativa L.)

“…(Zerpa-Catanho et al, 2019), X Triticosecale Wittmack (Alvarez et al, 2019) y Baccharis spp. (Moreno-Pizani et al, 2019). En arroz, se ha utilizado el "Germinator" para calcular curvas de germinación (Onwimol et al, 2016), sin embargo, el conteo de semillas germinadas se realizó de forma manual, no de forma automatizada.…”
