Effect of Indole-3-Butyric Acid on Clonal Propagation of Swietenia macrophylla through Branch Cutting

Abstract

The study discloses the scopes of clonal propagation Swietenia macrophylla through branch cutting treated with IBA. A total of four hundred cuttings were used with four replications to assess the rooting ability. The study exposed significant (p<0.5) difference of rooted cuttings among the treatments. The highest (62.51%) rooting percent was observed in cutting with 0.4% IBA treatment. In addition, root number and its length per cutting were increased with increasing IBA concentration (p<0.5). The experiment showed significant (p<0.5) difference of sprouting among the treatments. The highest (67.27%) percent of sprouting was observed in cuttings with 0.4% solution, which showed a similar fashion of percent of rooting. The study also showed significant (p<0.5) difference of shoot number per cutting, the length of the longest shoot, and number of leaves per cutting among the treatments. The overall survival of rooted cuttings after transfer to polybag significantly (p<0.5) differed among the cuttings treated with different IBA solution. The highest survival percentage (69.67%) was observed in the cuttings rooted with 0.4% IBA treatment and the lowest (55.6%) survival was found in cuttings treated with control. The use of 0.4% IBA treatment is suggested for rooting of juvenile leafy branch cutting of S. macrophylla.

Shoot position, cutting types and auxin treatments influence rooting response on Tecoma stans

“…Applications of auxin enhanced rooting and root quality in many tree species (Hartmann et al, 2018). IBA at 4000 ppm induced maximum rooting and produce high quality planting stock in Swietenia macrophylla (Azad and Matin, 2015). While for Duranta erecta 5000 ppm was the best for rooting and furthers than that the inhibitory effects on the rooting was apparent (Shiri et al, 2019).…”

“…The use of cuttings from stems, leaves, roots or terminal buds is considered as the most commonly applied technique due to its practicability and simplicity. It is well known that the success of rooting of woody stem cuttings, in the majority of ornamental plants, depends mainly on the physiological stage of the mother plant, the time of planting of the cutting (Hartmann et al, 2018) and the type of growth regulators used (Azad and Matin, 2015;Azad et al, 2016, Singh andRawat, 2017). The prevailing environmental conditions in the nursery i.e., light, temperature and humidity play an important role in rooting and succeeding growth and development of cuttings (Hartmann et al, 2018).…”

“…Little information is available on how the physiological age of the tissue influences the rooting in T. stans cuttings (Cerveny et al, 2006). The seeds of T. stans are small in size, membranous wings and long viability (Reno et al, 2007), which spread them easily by wind and the stem and roots cuttings has ability to precede roots (Biondi et al, 2008). The vegetative propagation in ornamental plant like T. stans is very important due to two reasons.…”

Effect of Naphthalene Acetic Acid on the Adventitious Rooting in Shoot Cuttings ofAndrographis paniculata(Burm.f.) Wall. ex Nees: An Important Therapeutical Herb

“…In 2011, Raji and Osman [13] showed that hormonal factors greatly influence the adventitious rooting in Stevia rebaudiana, a commercially important sweetening medicinal herb and higher concentration (2.3 mM) of IBA induces maximum number of roots within short time. In another study, Azad and Matin [14] concluded that the use of 0.4% IBA for rooting in juvenile leafy branch cutting of Swietenia macrophylla would be effective for mass propagation. Yan et al [12] investigated significant role of NAA in the adventitious rooting in Hemarthria compressa.…”

Responses of IBA on rooting, biomass production and survival of branch cuttings of Santalum album L., a wild threatened tropical medicinal tree species

“…The cuttings of S. album rooted well in the present study ( Figure 01). Rooting percent was varied 1.32fold (70.1 -92.6%); average root number per cutting, 3.8-fold (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19); and average root length, 3.1-fold (3.1-9.6 cm) among the various IBA treatments. The highest rooting percent was observed in 0.8% IBA concentration (T3) and lowest rooting percent was observed in control (T0).…”
