Response of black mulberry onto white mulberry rootstock to stenting (cutting-grafting) techniques and IBA concentrations

Abstract

Ornamental black mulberry (Morus nigra L.) is used in landscape. Ornamental black mulberry which has high shade, tolerates air pollution and wind. White mulberry (Morus alba L.) is proper for kind of soils conditions. Therefore, this research was conducted to investigate the effects of stenting methods and IBA levels on some characters of black mulberry scions onto white mulberry rootstock for the first time. For this purpose, an experiment was carried out as factorial in completely randomized design with 10 replications. Two factors were including two stenting method (splice and omega) and three levels of Indole-3-butyric acid (0, 500 and 1000 mg L-1). Three months after grafting, percentage of rootstock callus formation, percentage of rooting, percentage of leaf formation, number of leaf formation, the longest shoot and the longest root formation were measured. Results showed that the effect of stenting method was significant on all of evaluated parameters and splice method was superior to omega method. Also, the effects of different levels of IBA were significant on all of measured traits and they are increased by increasing the levels of IBA and the best was with 1000 mg L-1. The interaction effects of these factors are significant on all of measured characteristics except for percentage of rootstock callus formation and rooting percentage. In conclusion, the stenting via splice method had higher success in comparison with omega method and the morphological traits increased by increasing the application of higher levels of IBA. The application of stenting method by splice plus 1000 mg L-1 IBA which was carried out for the first time is recommended for reproduction of ornamental black mulberry onto white mulberry.

Effect of two different base cuts and indole-3-butyric acid (IBA) doses on rooting of stem cuttings of wild Silene compacta Fischer

“…Auxins are used to stimulate the development of roots (Assumpção Bastos et al, 2020). The most widely used of this auxin group is indole-3-butyric acid (IBA) (Cassol et al, 2017;Azad et al, 2018;Costa Junior et al, 2018;Pêgo et al, 2019;Dias Bezerra et al, 2020;Singh et al, 2021;Adiba et al, 2022;Solgi et al, 2022;Xie et al, 2023).…”

Successful grafting elite cocoa clones (Theobroma cacao L.) as a function of the age of rootstock

“…Indeed, improved cocoa plant materials with a high and stable yield elaborated by the National Agronomic Research Center of the past decade [ 7 ] are available even though they are not yet been released to farmers. One of the cost-effective approaches to rehabilitate these orchards while reducing the juvenile phase, is to go for the vegetative propagation method by grafting which is most likely the most appropriate solution [ [8] , [9] , [10] ]. Grafting consists of stimulating the assembly cambiums of two plants to develop a single plant.…”

Exogenous hormones supplementation improve adventitious root formation in woody plants

“…Compared to seed propagation, clonal propagation is a simpler, faster, and more efficient method to rapidly expand millions of cuttings from elite germplasms ( Gonin et al, 2019 ; Solgi et al, 2022 ). Adventitious roots (AR) formed from above-ground organs such as stems and leaves are crucial for clonal propagation, which is mainly controlled by the balance of endogenous and exogenous hormones ( Lakehal and Bellini, 2019 ).…”
