Initial development of peach rootstock genotypes propagated by herbaceous cuttings

Abstract

<jats:p>Abstract The peach tree is a temperate fruit tree propagated by grafting with the scion cultivar and the rootstock from seeds, generating low uniformity, a viable alternative is propagation by herbaceous cuttings. The objective of this study was to evaluate the performance of different genotypes of peach rootstock propagated by herbaceous cuttings. The experiment was carried out with standardized cuttings of 15 cm in length treated with 3,000 mg L-1 of IBA solution, then were transplanted into 3 L polyethylene bags. A completely randomized design with five replications was adopted, each plot consisting of three plants. Sixteen peach genotypes from UFV breeding program were tested: 713-3, 713-6, 713-7, 713-10, 813-2, 813-3, 813-5, 813-15, 913-3, 913-6, 913-11, 913-17, C6, C7 and C8. After 80 days the following parameters were evaluated: stem length (cm), stem diameter (mm) and internode length (cm). Data were subjected to analysis of variance by the F test and averages compared by the Scott-Knott test at a 5% probability level with the GENES statistical software. It can be concluded that the lower initial development was observed in genotype 1113-11 and the highest initial development was from genotypes 713-13 and 813-5.</jats:p>

Qualidade físico-química de ameixas ‘Letícia’ produzidas sobre porta-externos clonais e em plantas autoenraizadas, no meio-oeste de Santa Catarina

“…O conhecimento da interação entre o porta-enxerto e a cultivar copa é de fundamental importância na tomada de decisão por técnicos e fruticultores, para a correta definição das mudas a serem adquiridas. Além de influenciar as características vegetativas da cultivar copa, o porta-enxerto também pode promover alterações na qualidade dos frutos e na produtividade (SZYMAJDA et al 2019, OLIVEIRA et al 2020, SANTANA et al 2020.…”
