Qualidade da semente do gergelim preto (Sesamum indicum L.) em diferentes épocas de colheita

Abstract: RESuMo: O objetivo do presente estudo foi avaliar a qualidade da semente do gergelim preto colhida em diferentes épocas após a semeadura. As sementes utilizadas foram provenientes de quatro épocas de colheita (122, 129, 136 e 143 dias após semeadura). A avaliação da qualidade das sementes foi determinada pelo teste de germinação, primeira contagem de germinação, comprimento de plântulas, teste de condutividade elétrica, e massa de 100 sementes. Os dados foram submetidos à análise de variância, e, para avaliaçã… Show more

“…From this point, a downward trend begins in both treatments. Analyzing the vigor of black sesame seeds, using the first count test, Nobre et al (2013) also observed an increase in vigor, as the harvests were being carried out, reaching a maximum level from which a tendency of reduced quality in the seeds was observed.…”

“…According to Nobre et al (2013), seed size increases rapidly after fertilization, reaching its maximum in a short time, in relation to the total duration of the maturation period. This rapid growth is due to the multiplication and development of embryo cells and reserve tissues.…”

“…However, these reductions were not as significant points to derail the delay in crop seeds. Evaluating seed of Sesamum indicum L., Nobre et al (2013) observed that the values of percentage of normal seedlings obtained through the first count test showed the seeds harvested at 143 DAS, as the average, and different from the others.…”

“…Podemos destacar que o óleo da semente de gergelim apresenta elevada qualidade nutricional devido à presença de ácidos graxos insaturados, como oléico (47%) e linoléico (41%). Além disso, o gergelim é rico em lecitina, um fosfolipídio que desempenha importante função no organismo, sendo que uma de suas funções consiste em manter dissolvidos os lipídios em geral, especialmente o colesterol no sangue, evitando arteriosclerose (Nobre et al, 2013). Já a amêndoa da castanha do caju é composta principalmente pelos ácidos graxos oléico (C18:1) e linoléico (C18:2).…”
