Analysis of Butia odorata (Barb. Rodr.) Noblick seeds of fruits collected at three maturation stages

Abstract

Butia odorata (Barb. Rodr.) Noblick is a palm species that has potential for economic and environmental applications. The aim of this study was to evaluate the seed viability of a B. odorata population using two methods, as well as the water content at three ripening stages, the average number of fruits per infructescence, and the thousand-diaspore weight. Fruits and seeds were analyzed from the beginning of ripening stage to the partial dehiscence stage. The percentage humidity of the diaspores collected from the beginning of ripening to the dehiscence of fruits ranged between 16.8% and 19.8%. However, one week after pulping, when the seeds were maintained in a dry and ventilated environment, the water content decreased to 11.06%, regardless of the fruit ripening stage. The average mass of 1000 diaspores was 1.9 kg, with variation among the mother plants. We recorded an average of 860 fruits per infructescence and around 1,570 viable seeds. Around 2% of these seeds lacked an embryo. The viability was 83%.

“…For the morphometric analysis, fully developed leaves, inflorescences, and infructescences in the ripening stage were collected. For the germination analysis, the seeds were obtained by selecting fruits and removing their pulp according to previous methods (Fior et al, 2018). Therefore, 20 healthy and ripe fruits of each individual were selected (120 in total) for morphometric analysis, morphological characterization, and verification of the presence of seeds.…”

“…É importante ressaltar que na natureza os processos de superação de dormência ocorrem naturalmente, por ação de microrganismos, fungos ou ácidos fracos do solo e pela ação mecânica e ácida dos tratos digestivos de animais (FERNANDES et al, 2018). Lucas et al (2018) avaliaram a superação de dormência em espécies do gênero Myrsine, comparando a germinação de sementes coletadas em plantas com outras retiradas das fezes de aves e mamíferos, encontrando resultados positivos e satisfatórios, confirmando que a passagem pelo trato digestório dos animais promoveu a superação da dormência.…”
