Viabilidade E Métodos Para Superação De Dormência E Análise Biométrica Das Sementes De Puerária

Abstract: A Pueraria phaseoloides é uma espécie forrageira, de importância na Amazônia devido ao uso na nutrição animal e correção de solo e muito utilizada como cobertura verde, porém esta espécie apresenta altos índices de dormência. A pesquisa foi realizada com o objetivo de verificar a possibilidade de superar a dormência por meio de cinco tratamentos, escarificação com punção, água por 24 horas, água por 8 horas, água a 80 °C por 5 minutos, lixa mais a testemunha, paralelamente, avaliou-se a germinação destas semen… Show more

“…When studying the same species, Pinheiro et al (2019) found that the fresh mass of the seed was the one with the highest coefficient of variation (CV = 19.51%). These results corroborate our findings since a higher coefficient of variation was also observed in the fresh weight of the seeds (CV = 18.37%).…”

“…To solve the problem of hard seeds it is recommended to overcome dormancy. Pinheiro et al (2019) did not perform color selection and obtained a germination percentage of around 32% in a study on the viability and overcoming of Pueraria seeds; when they overcame dormancy, they germinated to 96% with the abrasive scarification method.…”

“…To obtain the fresh mass of the seeds individually, a heterogeneous sample was used, one unit/seed weighed on a precision analytical balance, where 99 units were evaluated. Afterward, measurements of the threedimensional dimensions of the seeds were performed as pre-established by Pinheiro et al (2019). The measurements were determined according to the location of the hilum in the seeds; then, from the hilum to the opposite base, the length was measured, sides of the median region of the greater amplitude of the seeds were considered the width, the thinner apparent side was determined as the thickness (Figure 1).…”
