Low amenability of the eucalypt, Corymbia torelliana 9 C. citriodora, to vegetative propagation has limited its establishment in plantations. This study determined whether rooting capacity and cutting vigour varied along the central shoot of Corymbia seedlings, and whether these differences are related to stem development and hormone concentrations. Dual-node cuttings were harvested from five positions (nodes 1/2, 3/4, 5/6, 7/8 and 9/10) along the seedling shoot (S1), and cuttings were treated with one of four levels of indole-3-butyric acid (IBA). Root formation, root and shoot growth, stem anatomy, and the concentrations of indole-3-acetic (IAA) and abscisic acid (ABA) were assessed at each shoot position. The central node of the rooted cuttings was harvested for fresh cuttings to observe whether maturation emerged in ramets (S2) from the different ortet positions. Rooting and vigour were highest from the most-apical seedling nodes (7/8 and 9/10 in S1), which had less lignification and sclerenchyma development than morebasal nodes (1/2, 3/4 and 5/6). IAA and ABA concentrations differed little between the seedling nodes. In contrast, cuttings from the ramets (in S2) had similar rooting, vigour, lignification and sclerification to each other, but there were large differences in IAA and ABA concentrations depending on their previous point-of-origin in the seedling. High doses of IBA reduced rooting. Rooting and vigour were related to lignification and sclerenchyma development rather than IAA or ABA concentrations. Mass vegetative propagation of C. torelliana 9 C. citriodora is achievable because mean rooting percentages in S1 and S2 were 61 and 68 %, respectively, using cuttings from small seedling ortets and their ramets.

The availability of single assai palm (Euterpe precatoria) seedlings with good quality is a fundamental requirement to expand the cultivation of the species. This study aimed to assess the use of fruit agro-industry residues as substrate for producing single assai seedlings. The experiment was carried out under nursery conditions, in a completely randomized design, with four replications and eight plants per plot. Fifteen treatments were evaluated: a commercial substrate, four dry and crushed agro-industrial residues (Brazil nut shell, acerola pit, assai pit and cupuassu peel) and ten combinations of these materials in the proportion of 1:1. The following variables were also measured: shoot height; stem diameter; number of leaves; shoot, root and total dry mass; and Dickson Quality Index score. The substrate formulated with Brazil nut shell + acerola pit stood out for promoting a higher growth and dry biomass, resulting in seedlings with a better quality. The pure assai pit residue was not efficient for producing seedlings, but it showed a good potential when mixed in equal proportion with other materials (e.g. Brazil nut shell and cupuassu peel). A disponibilidade de mudas de açaizeiro solteiro (Euterpe precatoria) de boa qualidade é requisito fundamental para a expansão do cultivo da espécie. Objetivou-se avaliar a utilização de resíduos de agroindústrias frutíferas como substrato para a produção de mudas de açaizeiro solteiro. O experimento foi conduzido em condições de viveiro, em delineamento inteiramente casualizado, com quatro repetições e oito plantas por parcela. Quinze tratamentos foram avaliados: um substrato comercial, quatro resíduos agroindustriais secos e triturados (casca de amêndoa de castanha-do-Brasil, caroço de acerola, caroço de açaí e casca de cupuaçu) e dez combinações desses materiais na proporção 1:1. Também foram mensuradas as seguintes variáveis: altura da parte aérea; diâmetro do colo; número de folhas; massa seca da parte aérea, raiz e total; e Índice de Qualidade de Dickson. O substrato formulado com casca de amêndoa de castanha-do-Brasil + caroço de acerola destacou-se por promover maior crescimento e biomassa seca, resultando em mudas de melhor qualidade. O resíduo de caroço de açaí puro não foi eficiente para a produção de mudas, mas apresentou bom potencial quando em mistura de igual proporção com outros materiais (p. ex. casca de amêndoa de castanha-do-Brasil e casca de cupuaçu).
