“…OLIVEIRA et al (2005) observed that the temperature causes effect both on the percentage of germination and germination speed index in Annona montana; also, the optimum temperature found for germination is around 30 °C, as can be observed in this study (Table 4).…”

Seedling quality is crucial to obtain vigorous plants in the field. This study aims to evaluate the emergence and development of soursop seedlings in different substrates in protected environments. The experiment was conducted at the Mato Grosso do Sul State University and carried out us ing five protected environments: greenhouse, greenhouse with thermo-reflective screen, nursery with monofilament screen, nursery with thermo-reflective screen, and nursery with palm thatch. The substrates (S) consisted of cattle manure (M), humus (H), cassava branches (C), and vermiculite (V) as in the following ratios: S1 = H + V (1:3), S2 = H + V (1:1), S3 = H + V (3:1), S4 = H + C (1:3), S5 = H + C (1:1), S6 = H + C (3:1), S7 = M + V (1:3), S8 = M + V (1:1), S9 = M + V (3:1), S10 = M + C (1:3), S11 = M + C (1:1), S12 = M + C (3:1), S13 = H + M + V (1:1:1), S14 = H + M + C (1:1:1), and S15 = H + M + V + C (1:1:1:1). For the statistical analysis, each of those environments was considered as an experiment in which was used the completely randomized design; subsequently, it was performed a combined analysis of them. In summary, the greenhouse with thermo-reflective screen and combined substrates with "M + V" promote greater development of the seedlings. High concentrations of "V" or "C" cause no beneficial effect on soursop seedlings. KEYWORDS:Annona muricata; cattle manure; cassava branches; vegetable ambience. MUDAS DE GRAVIOLEIRA: EMERGÊNCIA E DESENVOLVIMENTO SOB DIFERENTES AMBIENTES DE CULTIVO E SUBSTRATOS -PARTE IRESUMO: A qualidade da muda é fundamental para obtenção de plantas vigorosas no campo. Desta forma, o presente trabalho teve como objetivo avaliar a emergência e o desenvolvimento de mudas de gravioleira, em diferentes substratos, no interior de ambientes protegidos. O experimento foi conduzido na Universidade Estadual de Mato Grosso do Sul, onde foram empregados cinco ambientes protegidos: estufa agrícola; estufa agrícola com tela termorrefletora sob o filme; viveiro agrícola coberto com tela de monofilamento; viveiro agrícola coberto com tela termorrefletora e viveiro coberto com palha. Os substratos foram constituídos por esterco bovino (E), húmus (H), ramas de mandioca (M) e vermiculita (V), nas seguintes proporções: S1 = H + V (1:3); S2 = H + V (1:1); S3 = H + V (3:1); S4 = H + M (1:3); S5 = H + M (1:1); S6 = H + M (3:1); S7 = E + V (1:3); S8 = E + V (1:1); S9 = E + V (3:1); S10 = E + M (1:3); S11 = E + M (1:1); S12 = E + M (3:1); S13 = H + E + V (1:1:1); S14 = H + E + M (1:1:1); e S15 = H + E + V + M (1:1:1:1). Cada ambiente foi considerado um experimento, sendo adotado o delineamento inteiramente casualizado e, posteriormente, análise conjunta dos mesmos. Em síntese, a estufa agrícola com tela termorrefletora sob filme e os substratos combinados com "E + V" promovem maior desenvolvimento de mudas. Altas concentrações de "V" ou "M" provocam efeito não benéfico às mudas de gravioleira. PALAVRAS-CHAVE:Annona muricata; esterco bovino; ramas de mandioca; ambiência vegetal.

“…Experiments show and evidence the differentiated response according to the species, and Lamarca et al (2011) observed a wide adaptation to the emergence of seeds of some species of Eugenia in the most diverse temperatures tested, with germination and development of normal seedlings in the temperature range of 20 to 30ºC, being still indifferent to the temperature alternation (20/30 and 20/35ºC) and also reported by Lima et al (2007), who found higher rates for 'urucuzeiro' seeds at temperatures of 25, 30ºC and alternated between 20-30ºC. Silva et al (2006) observed better results for 'bacabinha' seeds when submitted to a temperature of 30ºC the same was verified by Oliveira et al (2005) for false annona muricata and by for 'jabuticabeira'. In each column, for each factor, averages followed by the same capital letter do not differ from each other by the "Tukey test", at 5%…”

-The reality of Brazilian fruit farming is demonstrating increasing demand for sustainable information about native and exotic fruit, which can diversify and elevate the efficiency of fruit exploitation. Research on propagation of fruits tree is very important so that it can provide a protocol for suitable multiplication of this fruitful. Due to the great genetic diversity of rambutan plants, it is recommended the use of vegetative propagated plants. This research aimed to evaluate the propagation of rambutan by cuttings, layering and grafting, as well as seed germination and viability without storage. The results of this research indicate that this species can be successfully propagated by layering, grafting and seeds. We also observed that the germination percentage of seeds kept inside the fruits for six days were not influenced by the different substrates used in this experiment. Index terms: Nephelium lappaceum L, grafting, layering, cuttings.AVANÇOS NA PROPAGAÇÃO DA RAMBUTEIRA RESUMO -A realidade da fruticultura brasileira tem demostrando crescente demanda de informações sustentáveis sobre frutíferas nativas e exóticas, as quais possam diversificar e elevar a eficácia da exploração de frutas. Pesquisas em propagação em frutíferas tem grande importância para que se possa fornecer um protocolo para adequada multiplicação dessa frutífera. Devido a grande diversidade genética das plantas de rambutan, para estabelecimento de pomares comerciais da cultura, recomenda-se o uso de plantas propagadas vegetativamente. Este trabalho teve como objetivo avaliar a propagação de rambuteira por estaquia, alporquia, enxertia, bem como a germinação por sementes e a viabilidade no armazenamento. Pelos resultados dos trabalhos nota-se que a frutífera pode ser propagada por alporquia, enxertia e por sementes, e se existir a necessidade de armazenamento de sementes que não ultrapasse um período de seis dias e sejam mantidas dentro dos frutos, não houve diferenças consideráveis na germinação nos substratos testados neste experimento. Termos para indexação: Nephelium lappaceum L, enxertia, alporquia, estaquia.
