“…Statistical difference for root dry matter and total dry matter of the seedlings. These results are different from those found by Gomes et al (2008) found the highest results for the development of lettuce seedlings when using Bioplant® as a substrate and by Dutra et al (2013) when using alternative substrates in the production of canafístula seedlings. The difference of results can be related to the commercial substrate favoring the densification that hinders the growth of the root system of the micropropagated seedlings of minirose since the developed roots are very weak and sensitive when compared the roots developed by the lettuce, damaging the absorption of essential nutrients to the development of seedlings.…”

The transition from heterotrophism to autotrophism in acclimatization is a delicate process for most species. The objective of this work was to evaluate combinations of regional substrates of the Brazilian Northeast in the acclimatization and morphological development of minirose (Rosa chinensis 'Minima') seedlings. The experiment was carried out in a greenhouse using seedlings with 30 days of in vitro culture. The treatments were constituted by: 1) dry coconut powder; 2) 75% dry coconut powder + 25% rice husk; 3) 50% dry coconut powder + 50% rice husk; 4) 75% dry coconut powder + 25% charcoal rice husk; 5) 50% dry coconut powder + 50% carbonized rice husk; 6) 100% vermiculite; 7) 50% vermiculite + 50% dry coconut powder; 8) commercial substrate; 9) 75% sand + 25% dry coconut powder and 10) 50% sand + 50% dry coconut powder. After 21 days, the following characteristics were evaluated: survival percentage, leaf number, shoot height, dry matter of shoot and root and total dry matter. The regional materials tested showed a good choice of substrates to be used in the acclimatization of minirose seedlings. The vermiculite presented the worst results in the characteristics evaluated. Dry coconut powder as substrate should be used in mixtures with other materials to provide better acclimatization conditions. The use of 50% dry coconut powder + 50% rice husk provided a best development and growth of minirose seedlings (Rosa chinensis 'Minima') than other tested substrates

“…Lettuce is the most cultivated leafy vegetable and an important part of the Brazilian diet (LOPES et al, 2007;MEDEIROS et al, 2007), and it is common to use organic substrates for the production and development of its seedlings (GOMES et al, 2008). This study aimed to assess (1) the amount of Trigoniulus corallinus millipedes sufficient for transforming waste into organic compost; (2) the main physicochemical characteristics of compost; and (3) compost efficiency when used as a substrate for the production of lettuce seedlings.…”

“…Lettuce seedlings with characteristics similar to those of the lettuce produced in this study (Table 2) were produced by GOMES et al (2008) in a substrate with a mixture of earthworm humus (70%), rice husk (30%), and phosphate, after 21 days, with fresh and dry mass from the aerial part at 0.37g and 0.03g, respectively.…”

“…Entre os materiais frequentemente utilizados para a formação de mudas de hortaliças, estão o substrato comercial Tropstrato ® (Plantmax ® ) e a vermiculita, porém outros materiais têm sido estudados para serem utilizados em misturas, tais como a casca de arroz carbonizada (GOMES et al, 2008), a fibra da casca de coco verde (CARRIJO et al, 2002) e o resíduo de algodão (COSTA et al, 2007). Esses e outros compostos podem ser utilizados objetivando promover melhores condições físicas e químicas para o crescimento das plântulas (GRASSI FILHO et al, 2004) e reduzir o custo de produção das mudas.…”

Resumo: O objetivo do trabalho foi avaliar o efeito da incorporação de resíduo de sisal ao substrato comercial sobre a emergência e a qualidade de mudas de jiló e brócolis. Os experimentos foram realizados em casa de vegetação com sombrite 50% no Departamento de Tecnologia e Ciências Sociais da UNEB, em Juazeiro, BA, utilizando-se sementes comerciais de jiló e brócolis. Nas duas espécies, os tratamentos consistiram na incorporação de diferentes porcentagens de resíduo de sisal (RSL) ao substrato comercial Tropstrato ® . Foi incorporado: 0, 10, 20, 30, 40, 50, 60 e 80% do RSL ao substrato comercial. Determinou-se o índice de velocidade e a porcentagem de emergência das plântulas, e aos 26 dias após a semeadura foram determinadas as seguintes características: comprimento de raiz e da parte aérea, diâmetro do colo, número de folhas, volume de raízes e massa seca da parte aérea e de raízes. O resíduo de sisal pode ser incorporado ao substrato comercial Tropstrato ® na formação de mudas de jiló e brócolis sem interferir na sua qualidade, sendo mais indicada a incorporação 50% do resíduo de sisal ao substrato comercial. Palavras-chaves: Agave sisalana, Solanum gilo, Brassica olerarea, plântulasAbstract: The aim of this study was to evaluate the effect of sisal residue incorporation the commercial substrate on the emergency and the quality of eggplant and broccoli seedlings. The experiments were performed in a greenhouse with 50% shade at Department of Technology and Social Sciences of UNEB, in Juazeiro, BA, using commercial seeds of eggplant and broccoli. In both species, the treatments consisted of the incorporation of different sisal residue percentages (SLR) the commercial substrate Tropstrato ® . Was incorporated: 0, 10, 20, 30, 40, 50, 60 and 80% of SLR at the commercial substrate. Determined the speed index and the percentage of seedling emergence and at 26 days after sowing were determined the following characteristics: length of root and shoot, stem diameter, number of leaves, root volume and dry weight of shoots and roots. The sisal residue can be incorporated into the commercial substrate Tropstrato ® at the formation of eggplant and broccoli seedlings without impinging on the quality, 50% incorporation of more appropriate sisal residue the commercial substrate.
