Propagation of white mulberry Morus alba L. fruitless cultivar using different cutting times and IBA.

Abstract

The white mulberry Morus alba L. is an interesting tree that widely planted throughout the world for various uses. The effort was made in this study to propagate the fruitless cultivar of Morus alba L. by hardwood cuttings; comparing different cuttings collection time with using various concentrations of IBA (Indole-3-Butyric Acid) solution. Results showed that taking and planting cuttings on March 1st, gave the best survival percentage of rooted seedlings, which was (20.83%) compared to February 8th (16.33%) and March 22nd (12.5%).Cuttings treated with different concentrations of IBA significantly increased success percentage; 58.33, 66.67, 50.00 and 20.83% for 2000, 1500, 1000 and 0ppm respectively. Furthermore, the combination effect of previous factors had positive effects on studied characters; the heighest values of success rate of rooting (66.67%) from cuttings taken on March 1st and immersed in 1500ppm of IBA solution (T7), while success rate of rooting (58.33%) and all other qualitative parameters of shoots height (70cm), vegetation fresh weight (74.9g), vegetation dry weight (24.06g), root length (41.17cm) roots fresh weight (5.26g), roots dry weights (1.5g), number of leaves per plant (32.33), and leaf area (84.32cm2) were obtained from cuttings taken on the same time but treated with 2000ppm. The results recommend taking cuttings on March 1st, and using 2000ppm of IBA directly before planting to enhance cuttings survival percentage and seedlings quality.

Studies on orgafol: A promising organic growth promoter, on the growth and development of mulberry cuttings

“…Orgafol has a higher leaf area when compared with the other treatments. These findings are coinciding with the findings of Hawramee et al, (2019) [9] . Similar results were observed in the findings of Shah et al, (2006) [22] in Ficus binnendijkii, El-Leithy et al, (2006) [4] in Salvia officinalis, Mady (2009) [16] in faba bean, Ahmed et al,…”

“…Orgafol has the highest root length when compared with the other treatments. These findings are coinciding with the findings of Husen (2003) [10] , Intorrathed et al, (2018) [11] , Singh et al, (2014) [23] , Hawramee et al, (2019) [9] in Morus alba, Shah et al, (2006) [22] , Erturk et al, (2010) [7] , Singh (2018) [25] , Murthy et al, (2012) [18] in Matigara black and similar results were observed in the findings of Kumari et al, (2018) [15] in Morus alba, Rongting et al, (2017) [21] and Fatema et al, (2005) [8] in groundnut. The effect of the treatments on shoot length on different days after planting is shown in Table 3.…”

“…Orgafol has more number of leaves when compared with other treatments. These findings are coinciding with the findings of Intorrathed et al, (2018) [11] , Singh (2018) [25] , Khan et al, (2007) [14] , Singh et al, (2014) [25] , Hawramee et al, (2019) [9] and similar results were observed in the findings of Shah et al, (2006) [22] in Ficus binnendijkii, Mady (2009) [16] in faba bean, El-Tohamy et al, (2007) [6] in snap beans, Ahmed et al, (2011) [1] in potato, El-Tohamy et al, (2008) [5] in eggplant and Kumari et al, (2018) [15] in Morus alba. The effect of the treatments on leaf area on different days after planting is shown in Table 5.…”

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

“…It has been proved that the natural auxin (IAA) affect most aspects of plant physiology comprising root initiation and cell division. It is generally accepted that auxins have a certain role in the rooting initiation and therefore leads to control growth and development in plants, including lateral root initiation, root gravity response and other vegetative growth parameters (Aref Hawramee et al, 2019). IAA are synthesized in buds and leaves and moved to the bottom of cuttings and grafting unions (Hartman et al 2002;Izadi et al, 2013).…”

“…White mulberry is a shade tolerant tree and black mulberry can tolerate atmospheric pollution which is suitable for air polluted areas (Mohiuddin et al, 2011;Kobus-Cisowska et al, 2020). Mulberry trees are commonly propagated by cutting, grafting and tissue culture (Hussain et al, 2017;Aref Hawramee et al, 2019;Zenginbal and Demir, 2018).…”
