A Agricultura tem grande influência na economia rondoniense, mas o setor gera resíduos que podem ter diferentes destinações. E uma alternativa promissora para o destino final desses resíduos é o seu uso como substratos, minimizando assim impactos social, econômico e ambiental. O objetivo do trabalho foi avaliar os substratos obtidos a partir de diferentes concentrações resíduos agroindustriais, na germinação de Handroanthus serratifolius (Vahl) S. O. Grose. O delineamento utilizado foi o de blocos casualizados, cinco tratamentos e quatro repetições. Os tratamentos resultaram em diferentes combinações de areia e resíduo agroindustrial: T1 – 0%:100% (testemunha); T2 – 75%:25%; T3 – 50%:50 %; T4 – 25%:75%; e T5 – 0%:100%. Diariamente, foi avaliada a porcentagem de germinação (G%) e, após a estabilização da germinação aos 27 dias, foram calculados o índice de velocidade de germinação (IVG), tempo médio de germinação (TMG) e velocidade média de germinação (VMG) das sementes e as médias de germinação foram submetidas aos testes normalidade, homogeneidade a 5% de significância e análise de variância ao teste de Tukey (P ≥ 0,95). A porcentagem de germinação variou de 9% a 71%, e foi verificado 100% de sanidade das sementes e ausência de plântulas anormais. Verificou-se que o tratamento 2 apresentou diferença significativa entre os demais tratamentos, o substrato com os melhores resultados foi o T2 (G% = 71%; IVG =11; TMG = 17 dias; VMG = 0,0606 sementes.dia-1). O substrato com 25% resíduos + 75% areia destacou-se dos demais tratamentos, resultando nos melhores resultando na melhor germinação.

“…Therefore, the morphometry is fundamental to assist in seedling production and area recovery studies (Andrade et al, 2010). Despite its importance, this information is still scarce, taking into consideration the great biodiversity in the Brazilian biomes (Fonseca et al, 2013), andPagliarini et al (2014) described the results of this kind of research as being infrequent. In addition, knowledge about the fruit and seed chemical characteristics also enable indicating their potential use and being able to correlate these characteristics with the seed dispersal processes (Fernandes et al, 2021).…”

The Unonopsis guatterioides (Annonaceae) species provides wood which is used in rural construction projects, has leaves which are used in traditional medicine and its fruit is important in bird diets. This study aimed to evaluate the morphometry of seeds and fruits, their chemical composition, and the germination at different temperatures using seeds subjected to tegumentary dormancy break from fruits collected in a semi-deciduous seasonal forests in Mato Grosso do Sul, Brazil. The fruits under ripening showed a higher number of secondary metabolites and higher phenolic compounds. Morphometry results indicated that most seeds have length between 3.5 and 5.6 (81.3%), width between 8.1 and 9.0 mm (85.0%) and average weight of 0.28 g. The results indicate that there is a greater number of fruits with length ranging between 9.0 and 16.5 mm (74.8%), width between 9.0 and 12.0 mm (60.0%) and average weight of 1.33 g. Germination was strongly affected by temperature, reaching 58.0% and 62.0% of germinability at 30 °C and 25-35 °C, respectively, with seeds showing integumentary dormancy, requiring scarification.

“…After that, initial evaluations using sand at high temperatures indicated that this substrate was adequate to propitiate better germination rates [9]. Pagliarini et al [40] have mentioned that sandor commercial organic-based substrates are both acceptable to this species germination, even though these methods presented variations in the germination speed index. The present study data contributes to the previous information, that there are no substantial discrepancies between those methods.…”

Germination of<em> Hymenaea courbaril</em>: Storage Behavior, Origin, and Substrate

Hymenaea courbaril is an endangered species, promising to reforestation programs and mainly explored as a wood source. The available information concerning long-term storage methods, seed recalcitrance, parental, and substrate influence is scarce. This study focused on the seed behavior according to population origin and during one-year storage, also testing the efficiency of the low-temperature conservation. Variations between the uncertainty indexes were found to the studied populations after long-term storage. There was no significant loss of the germination potential in consequence of the prolonged storage period. Although, older seeds promoted gradually greater delayed germination. Germination speed, synchrony, and uncertainty indexes were substantially different between the -20° conservation and control. H. courbaril seeds are capable of long-term storage without losing their germination potential, indicating an orthodox behavior.
