“…In view of this, substrates T2 and T3, which presented values of 3.91 and 4.10, respectively, are the most suitable for the production of sibipiruna seedlings according to this test. These results corroborate those obtained by Gonçalves et al (2013), who found that substrates containing 15% sand + 65% soil + 20% poultry manure and 20% sand + 70% soil + 10% bovine manure provide better quality Acacia farnesiana seedlings.…”

The objective of this work was to evaluate the effect of different substrates on the production and quality of sibipiruna seedlings. The experimental design was a randomized complete block, with six treatments and eight replications. The treatments tested were: (T1): 5% organic compounds + 80% soil + 15% sand; (T2): 10% organic compounds + 75% soil + 15% sand; (T3): 15% organic compounds + 70% soil + 15% sand; (T4): 20% organic compounds + 65% soil + 15% sand; (T5): 100% commercial substrate (H. Decker®); (T6): 100% organic compounds. To determine the effect of the substrates on the production of sibipiruna seedlings, the shoot height, stem diameter, root length, dry mass of roots, dry mass of shoots, total dry mass and Dickson quality index were evaluated. In general, T2 and T3 showed the best responses with respect to the characteristics analyzed, providing better quality seedlings. Through the Dickson quality index performed at 120 days after transplanting, it is possible to conclude that with the exception of T6, the sibipiruna seedlings present satisfactory levels of quality for commercialization and field planting, and the best results are found with the use of different combined materials.Additional keywords: Dickson Quality Index; morphological characteristics; organic compound; sibipiruna. ResumoO trabalho teve como objetivo avaliar o efeito de diferentes substratos sobre a produção e qualidade de mudas de sibipiruna. O delineamento experimental utilizado foi o de blocos completos casualizados, com seis tratamentos e oito repetições. Os tratamentos testados foram: (T1): 5% de compostos orgânicos + 80% de solo + 15% de areia; (T2): 10% de compostos orgânicos + 75% de solo + 15% de areia; (T3): 15% de compostos orgânicos + 70% de solo + 15% de areia; (T4): 20% de compostos orgânicos + 65% de solo + 15% de areia; (T5): 100% de substrato comercial (H. Decker ® ); (T6): 100% de compostos orgânicos. Para determinar o efeito dos substratos sobre a produção das mudas de sibipiruna, avaliaram-se: altura da parte aérea, diâmetro do caule, comprimento da raiz, massa seca da raiz, massa seca da parte aérea, massa seca total e índice de qualidade de Dickson. De modo geral o T2 e T3 proporcionaram as melhores respostas em relação às características analisadas, proporcionaram mudas de melhor qualidade. Por meio do índice de qualidade de Dickson realizado aos 120 dias após o transplante, é possível concluir que com exceção do T6 as mudas de sibipiruna apresentam índices satisfatórios de qualidade para a comercialização e plantio a campo, sendo os melhores resultados encontrados na utilização de diferentes materiais combinados.Palavras-chave adicionais: características morfológicas; composto orgânico; índice de qualidade de Dickson; sibipiruna.Científica, Jaboticabal, v.45, n.

The objective of this work was to evaluate the phytotoxic effect of Brachiaria decumbens Stapf. on the morphometry of Eucalyptus urograndis plants, genetically modified hybrid of Eucalyptus urophylla S. T. Blake × Eucalyptus grandis W. Hill ex Maiden. Pots containing the eucalyptus plants were conditioned in protected environments in a completely randomized experimental design. The treatments were composed of aqueous extract of Brachiaria decumbens grass at different concentrations: 0% (control, distilled water only), 20%, 40%, 60%, 80% and 100% (g/L). On day 30 of the experiment, the following morphological parameters of the plants were evaluated: aerial part height, diameter of stem, aerial dry mass, root dry mass, total dry mass, and robustness index. The data were submitted to analysis of variance at the 5% level of significance, and a regression equation was constructed for the quantitative treatments. The results indicated that the Brachiaria decumbens grass extract did not have an inhibitory effect on aerial part height and robustness index. However, the extract at concentrations higher than 20% had negative effects on root dry mass, aerial dry mass, and total dry mass. For the diameter of the stem, only concentrations above 60% had an inhibitory effect.

Objetivou-se avaliar a influência de diferentes granulometrias do bagaço de cana para composição de substratos alternativos, constituídos a partir da mistura de um substrato comercial, na produção de mudas de angico-vermelho (Anadenanthera peregrina). O experimento foi conduzido em delineamento de blocos ao acaso, com três repetições, no esquema fatorial (5 x 2), sendo cinco substratos (100% Rohrbacher®; 75% Rohrbacher® + 25% Bagaço de Cana (75R+25BC); 50% Rohrbacher® + 50% Bagaço de Cana (50R+50BC); 25% Rohrbacher® + 75% Bagaço de Cana (25R+75BC); 100% Bagaço de Cana) e duas granulometrias (4 mm e 6 mm). Foram avaliados a altura da parte aérea (H), o Diâmetro de Coleto (DC), a Massa Seca da Parte Aérea (MSPA), a Massa Seca da Raiz (MSR) e a Massa Seca Total (MST); além das relações H/DC, H/MSPA MSPA/MSR e IQD (Índice de Qualidade de Dickson). Os substratos de granulometria 1 (passado em peneira de 4 mm), proporcionaram maior índice de germinação das sementes de angico-vermelho, ganho em altura e relação H/DC nas mudas da espécie. Os substratos alternativos 75R+25BC, 50R+50BC e 25R+75BC, além do substrato comercial Rohrbacher®, apresentaram potencial de uso na produção de mudas de angico-vermelho.
