Rooting of hardwood cuttings of Roxo de Valinhos fig (Ficus carica L.) with different propagation strategies

Abstract

RESUMO Enraizamento de estacas lenhosas de figueira (Ficus carica L.) cv. Roxo de Valinhos com diferentes estratégias de propagaçãoO objetivo deste trabalho foi avaliar o substrato, a época de coleta das estacas, a posição e a profundidade da estaca e o ambiente de propagação para o enraizamento de estacas de figueira 'Roxo de Valinhos', no sudoeste do Paraná. Foram realizados dois experimentos, na UTFPR, Câmpus Dois Vizinhos, com estacas lenhosas de figueira cv. Roxo de Valinhos. O primeiro utilizou delineamento experimental em blocos ao acaso, em fatorial 3 x 3 x 2 (substrato x ambiente x época de coleta), com quatro repetições de 10 estacas por parcela. As estacas foram coletadas nas primeiras quinzenas de julho e agosto. Os substratos foram areia, solo e a mistura destes [1:1 (v/v) fig (Ficus carica L.) with different propagation strategies Rooting of hardwood cuttings of Roxo de ValinhosThe objective of this study was to evaluate the substrate, cuttings collection time, the position and the cutting depth, and the propagation environment on rooting of 'Purple Valinhos' fig tree cuttings in Southwestern Paraná, Brazil. Two experiments were carried out at UTFPR, Câmpus Dois Vizinhos, with hardwoods cuttings from Roxo de Valinhos fig tree. The first experiment used a randomized block design, in 3 x 3 x 2 factorial (substrate x environment x collection time), with four replications of 10 cuttings per plot. The cuttings were collected in the first fifteen days of July and August. The substrates were sand, soil and the mixture of these [1:1 (v / v)]. The environments used were open sky, tunnel with plastic cover and tunnel with half-shade black net cover. The second experiment used a randomized block design, 2 x 2 x 3 factorial (shoot cutting position x soil cover x shoot cutting depth), with four replications of 12 cuttings per plot. In the factor position, the vertically (0 ° inclination) and inclined (45 ° inclination) shoot cuttings were evaluated. Soil cover was tested with mulching plastic cover or not. The tested depths were 1/3, 1/2 and 2/3 in relation to the total length of the shoot cutting. In both experiments, the following were analyzed: rooting and mortality indices, number of leaves and primary shoots, length of the three largest roots per cutting. It was conclude that, the protected environment with plastic cover on sand as substrate must recommended for the rooting of fig estaca, collecting them in the first half of July. The inclination position and cutting depth of the estaca and the substrate coverage with plastic mulching did not influence the results.

Propagation of Aloysia citriodora Palau Using Different Cutting Types under Light Intensity

“…The level of incident solar radiation may affect the physiological processes of cuttings and the early development of plants [12]. Literature indicates that cuttings propagated by Ficus carica L. [13] and Cornus alba L. [14] responded differently to shade levels but works with A. citrodora were not found, making it necessary to study and to investigate the light regimes in the cuttings production phase and the acclimatization processes.…”

Estado da arte da propagação vegetativa por estaquia de espécies arbustivo-arbóreas

“…Utilizando Ficus carica, tanto Souza et al (2019) quanto Nava et al (2014) obtiveram melhores resultados no inverno. Vale destacar que Nava et al (2014) compararam dois meses de inverno e, mesmo assim, obtiveram diferenças entre os dois momentos de instalação.…”

Vale destacar que Nava et al (2014) compararam dois meses de inverno e, mesmo assim, obtiveram diferenças entre os dois momentos de instalação. Paula et al (2009) também realizaram estudos com Ficus carica mas, à diferença dos trabalhos anteriores, os melhores resultados foram no final de outono, início da primavera e no verão.…”

Stem cuttings and substrates in Dovyalis asexual propagation

“…This difference in the results with the use of auxin can be motivated by the time of exposure to the phytohormone. In the cited study, dovyalis cuttings were exposed during 5 seconds, probably not enough time for a satisfactory auxin fixation in the exposed tissues (Nava et al, 2014).…”
