“…This variable expresses the capacity by which the seedlings have to use existing resources to produce higher rates of photosynthesis and biomass. Souza et al (2012), conducting a nutritional study on canafistula, concluded that the species has a high requirement of the nitrogen from chemical fertilizers. The organic substrates tested in this experiment, especially poultry manure (Table 1), are rich in nitrogen and, thus, have supplied the nutritional needs of canafistula.…”

-The objective of this study was to evaluate organic substrates in the production of canafistula (Peltophorum dubium) (Spreng.) Taub, cutieira (Joannesia princeps Vell.), jatoba (Hymenaea courbaril L.) and rubber tree (Hevea brasiliensis M. Arg.) seedlings, native trees with potential use in forest restoration programs. The design was completely randomized with 10 substrate formulations with 4 repetitions of 3 plants for the four species. The evaluated substrates consisted of soil, bovine manure (BM), poultry manure (PM), chemical fertilizer (CF) and sand, in different proportions. The experiment was concluded at the end of 180 days for canafistula, cutieira and rubber and 210 days for jatoba. At the end of these periods, the root (RDM), shoot (SDM) and total (TDM) the dry matters of the seedlings were determined. Quantification of AMF spores and normalization between samples through SPORES/RDM correction were also performed. The Scott-Knott test at 5% probability was applied. Regarding biomass production, only canafistula had significant difference among the tested substrates. In relation to sporulation, the highest values were observed in cutieira and rubber tree in substrate containing PM. The substrates composed of 40 or 50% soil + 20% sand + 30% or 40 PM for canafistula; 50% soil + 20% sand + 30% PM for cutieira; and for jatoba and rubber tree 60% soil + 20% sand + 20% PM, enabled the best results in terms of biomass production in seedlings and AMF sporulation.Keywords: Waste use; Arbuscular Mycorrhizal Fungi; Endangered Species. AVALIAÇÃO DE SUBSTRATOS E ESPORULAÇÃO DE FMAS NA PRODUÇÃO DE MUDAS DE ESPÉCIES FLORESTAIS NATIVASRESUMO -O objetivo do trabalho foi avaliar substratos orgânicos na produção de mudas de canafístula (Peltophorum dubium) (Spreng.) Taub., cutieira (Joannesia princeps Vell.), jatobá (Hymenaea courbaril L.) e seringueira (Hevea brasiliensis M. Arg.), arbóreas nativas com potencial uso em programas de restauração florestal. O delineamento utilizado foi inteiramente ao acaso com 10 formulações de substratos com 4 repetições de 3 plantas para as 4 espécies. Os substratos avaliados consistiram em misturas de solo, esterco bovino (EB), cama aviária de poedeiras (CA), fertilizante químico (FQ) e areia, em diferentes proporções. O experimento foi encerrado ao final de 180 dias para a canafístula, cutieira e seringueira e aos 210 dias para o jatobá. Ao final destes períodos foi determinado o peso da massa seca de raiz (MSR), da parte aérea (MSPA) e total (MST) das mudas. Foi realizada a quantificação de esporos de FMAs e a normalização entre as amostras por meio de correção ESPOROS/MSR. Foi aplicado o teste Scott-Knott a 5% de probabilidade. Quanto à produção de biomassa, somente a canafístula obteve diferença significativa dentre os substratos testados.

“…According to Souza et al (2012) the Cerrado soil is composed of about 46% of latosol. Latosol is characterized by a low availability of nutrients, acid reaction, low cation exchange capacity and low organic matter content, which among other features, lead to a poor absorption of nutrients by plants, especially nitrogen (N) and phosphorus (P).…”

The aim of this research was to evaluate the quality and photosynthetic metabolism of "uvaia" seedlings (Eugenia pyriformis Cambess.) on different substrates and water regimes. ), photosynthesis (µmol m -2 s -1 ) and efficiency of water use (µmol de CO 2 / mmol de H 2 O). Until their 150 th days, the seedlings had higher quality and photosynthetic metabolism when cultured with substrates containing latosol + sand + poultry litter on the two variations assessed and water retention capacity of 50%.

“…No studies were found to evaluate species in the natural regeneration phase. Young individuals (seedlings) are usually evaluated in experiments in a protected and controlled environment, with the objective of studying the BUE of nutrients in response to the fertilization of a certain nutrient, such as the studies developed by N.

“…The knowledge of nutritional aspects of native species is important in order to understand the establishment of these species in their origin sites, especially in areas with low nutrient availability soils, such as tropical soils (N. Souza et al, 2012). This information, when obtained specifically for natural regeneration species, which are in the initial phase of its development (Felfili, Rezende, Silva-Júnior, & M. A. Silva, 2010), combined with the knowledge of these species' autecology (Schorn & Galvã o, 2006) may subsidize the indication for use in reforestation.…”

The knowledge of the nutritional aspects of native species, mainly in natural regeneration, may be important for understanding their establishment, particularly in areas with low nutrient availability soils, such as tropical soils. This study aimed to determine the biological utilization efficiency (BUE) of the nutrients N, P, K, Ca, and Mg of forest species of natural regeneration in a Lowlands Dense Ombrophilous forest fragment in Pernambuco, Brazil. A phytosociological study of the fragment was carried out and were defined the ten species with the highest absolute density (AD). Three individuals per species were selected. The N, P, K, Ca, and Mg contents were determined in the sample leaves of the species, and the foliar biomass was determined "in loco". Nine individuals of each species were collected according to the following diameter intervals at the base (DBs): DBs<5 cm; 5≤DBs<10 cm and 10≤DBs<15 cm. The content, stock and BUE of nutrients were calculated per species. The BUE of nutrients by species varied according to the following decreasing order: P>Mg>K>Ca>N. The highest BUE of nutrients was of the species Protium heptaphyllum. In tropical soils of low natural fertility, the use of these species can be recommended in environmental reforestation projects. The difference in the nutritional demand of the forest species can indicate the planting of those with greater capacity of absorption and BUE of nutrients, being more efficient in areas of soils with low natural fertility like in the tropical forests. P content foliar biomass of the species varied from 1.33 to 2.45 g kg -1 , with a mean of 1.49 g kg 1 . P content in A. dolichocarpa was higher than of the other species (Table 4).Nutrient stock in the foliar biomass of natural regeneration species followed the decreasing order: N>Ca>K>Mg>P. This decreasing sequence varied according to species: T. spruceanum was N>Ca>Mg>K>P; C. densifolia was N>K>Ca>Mg>P; and P. heptaphyllum was N>Ca>K>P>Mg (Table 3). The highest nutrient stock were observed in B. rubescens (Table 4), due to the amount of biomass per area of the species (Table 3) N was the nutrient that presented the highest stock in the foliar biomass of the highest AD species, varying from
