Shading And Slow Release Fertilizer Effects On The Growth Characteristics Of Assai Seedlings (Euterpe oleracea)

et al. 2019

The objective of this work was to evaluate the initial growth of assai seedlings (Euterpe oleraceae) in response to shading and slow release fertilizer. The experiment was conducted at Embrapa Acre in a randomized block design using a 4 × 5 factorial scheme with three replicates and 10 plants per plot. The treatments consisted of four shade environments (20%, 30%, 50% and 75%) and five levels of slow release fertilizer (0.0, 2.5, 5.0, 7.5 and 10.0 kg m-3). The following characteristics were evaluated: plant height, number of leaves, stem diameter, leaf dry mass, stem dry mass, root dry mass, total dry mass, and seedlings quality index. The growth of assai seedlings was influenced by shade environment conditions and slow release fertilizer. Shade environment with 30% or 50% and a dose of 8 kg m-3 resulted in better quality seedlings.

RESUMOEm comunidades tradicionais e assentamentos rurais da Amazônia são comuns os processos de manejos com intuito de disponibilizar madeira para pequenas construções e diversos produtos florestais não madeireiros (PFNMs), como os frutos e plantas utilizadas na medicina popular. Sendo assim, objetivou-se descrever os aspectos florísticos e o potencial de utilização das espécies florestais de um fragmento de floresta ombrófila densa aluvial situada no estuário amazônico, Foz do Rio Mazagão, Estado do Amapá. Para conhecimento da estrutura florestal foram inventariadas 19 parcelas (3 ha de área total inventariada). Foram obtidos os dados dendrométricos como a altura total e circunferência, com nível de inclusão de circunferência à altura do peito (CAP) ≥ 30cm. Para avaliar o potencial de utilização madeireira, aplicou-se formulários para levantamento de informações socioeconômicas dos assentados, além da obtenção de informações na literatura existente sobre o assunto. A família com maior riqueza de espécies na amostragem total foi: Fabaceae com 17 espécies (26,15%). Dentre as espécies mais abundantes, a Mora paraensis (Ducke) Ducke (260), Pentaclethra macroloba (Willd.) Kuntze (104), Calycophyllum spruceanum (Benth.) Hook. f. ex K. Schum. (62) contribuíram com 426 indivíduos, 48,1% da densidade total amostrada. O H' para a área total foi de 2,959 nats/indivíduo, indicando que esse ambiente florestal apresenta diversidade florística compatível com o ecossistema de várzea. PALAVRAS -CHAVE: Etnoespécie, fitossociologia, manejo florestal.

“…Such information is fundamental to know the germination potential and use of each source, serving as an indicator of anticipation in obtaining better quality seedlings, as well as to assist in recommending and supporting programs for the recovery of degraded areas, conservation, resources and also to evaluate the genetic variability within populations of the same species (Mendonça et al, 2016;Ken-iti Yokomizo et al, 2016;Bardales-lozano et al, 2016;Silva Moura et al, 2016;Oliveira et al, 2016).…”

Andiroba (Carapa guianensis Aubl.-Meliaceae) is considered an Amazonian forest species with great potential for multiple use in natural forests. Because it is a native species of the Amazon rainforest, it has great socioeconomic importance for the extractive population due to the oil extracted from its seeds. The speed of emergence is an important factor in the establishment of seedlings, since the longer the seeds remain inside the soil, the seeds are in the soil, the greater the chances that the seeds will be attacked by fungi and soil insects. The objective of this work was to determinate the speed of andiroba emergence (Carapa guianensis Aubl.) seedlings and the development. The experiment was carried out in a greenhouse belonging to Federal Rural University of Amazonia (UFRA)-Capitão Poço, Brazil. Fruits of C. guianensis were collected in floodplain areas in northeastern of Pará. The treatments were arranged according to the seed mass. Were calculated 5 variables after sowing (emergence speed index; height; interference of the mass of andiroba seeds at the height of the seedlings stem; interference of the mass of andiroba seeds in the number of leaves; interference of the mass of andiroba seeds in the number of leaflets). The experimental design was completely randomized, consisting of 4 treatments with 5 replicates with 5 seeds per replicate (5 seeds per vessel), totaling 25 seeds per treatment. The data were statistically analyzed using the Tukey test at 5% probability with the software Assistat 7.6. The seed mass classes did not influence ESI (Emergence Speed Index). The seed mass promoted significant effects on 4 variables. The mass of the seeds of andiroba does not influence the ESI of seedlings for it own production. The heavy and very heavy seeds generated more developed plants.
