Study of indole butyric acid (IBA) effects on cutting rooting improving some of wild genotypes of damask roses (Rosa damascena Mill.)

Abstract

Rosa damascena is very important for essential oil production, medicinal properties and it is also widely cultivated as a garden rose. The Rose species is mainly propagated by stem cutting. In the present study, the effect of different levels of 0, 500 and 1,000 mg l-1 (quick dip method for 20 s) of indole butyric acid (IBA) on the rooting of 12 wild genotypes (including: Kurdistan 1 to Kurdistan 12) of R. damascena was investigated. The results show that the rooting ability of R. damascena differs significantly between the twelve genotypes. The highest rooting (79.56%) and callus production (69.08%), number of roots (8.33), root fresh and dry weights (361.80 and 244.74 mg, respectively) were recorded in Kurdistan 5 genotype with 1,000 mg l-1 IBA. The maximum root length (5.84 cm) was observed in Kurdistan 5 genotype with 500 mg l-1 IBA that showed a significant difference compared to the control treatment (0.96 cm). The highest number of leaves per bud (7.33 at 500 mg l-1 IBA) and number of buds (5.00 at 1,000 mg l-1 IBA) were recorded in Kurdistan 1 genotype. The current study demonstrated that the different genotypes of R. damascena were in a difficult-toroot state, which suggests that cutting treatment with 1,000 mg l-1 IBA overcame the problem of the difficult-to-root state, and it can also enhance the rooting percentage in the studied genotypes.

Determining the Rooting Ability of Hardwood Cuttings of Blueberry (Vaccinium corymbosum L.) cv. ‘Bluecrop’ Stored in Refrigerating Conditions

“…The promotion effect of IBA in rooting is mainly a result of its conversion to IAA in plant tissues. However, IAA which is needed for the process of rooting, is easily oxidized from peroxidases, whilst IAA released from IBA does not oxidize from peroxidases and remains in the base of the cutting (Zahra et al, 2012). The highest values of rooting percentage are definitely related to the time when cuttings were collected, the type of growth bioregulators and the type of substrate.…”

“…Subsequent to a numerous special requirements that this plant has, the production increase is limited if there is no way to overcome some of these specific factors conditional for the production of blueberry in larger areas. The use of hardwood cuttings is easier and at the same time is the most common method of vegetative propagation (Anderson & Woods, 1999). There are several successful methods of blueberry production in a vegetative way that could potentially be used to propagate blueberry V. corymbosum L. This is achieved using well-lignified hardwood cuttings, semi-lignified cuttings and soft-wood cuttings.…”

“…Application of auxin, especially indol butyric acid (IBA) is one of the most common and effective means to increase the culture rooting. IBA is more effective in the promotion of adventitious roots in stem cuttings (Waisel et al, 1991). The initiation of adventitious roots and their growth is an intensive metabolic process promoted by auxins and other growth regulators, leading to the increase of enzymatic activities for the synthesis of ARN and proteins (Legue et al, 2014).…”

Rooting and growth of root cuttings of two old rose cultivars ‘Harison’s Yellow’ and ‘Poppius’ treated with IBA and biostimulants

“…Roses growing without the share of a rootstock are easier to cultivate, because there is no need to remove the so-called "wild" layers. Propagation methods currently used are cuttings, suckers, layers [5], and micropropagation [6], but in the case of the old roses (groups occurring before 1867 [5]) and cultivars of species the standard methods often fail [7,8]. These difficult-to-root roses of different origin can be propagated by rhizome/root cuttings, e.g., for R. nitida Willd.…”

The Impact of Seasonal Changes in Plant Tissue on Rhizogenesis of Stem Cuttings of Once Blooming Roses

“…The process of rhizogenesis of historical roses by cuttings is considered to be rather long (10-12 weeks) and rooted cuttings are often of poor quality (Moroz, 2006;Monder et al, 2014;Nasri et al, 2015), especially when compared with modern roses, in which rhizogenesis lasts 4-6 weeks on the average (Costa et al, 2007;Pietrakowski, 2006;Wiśniewska-Grzeszkiewicz and Podwyszyńska, 2001). The rhizogenesis process in rose cuttings is known to be affected by many exogenous and endogenous factors, including the location in canopy (Hwnag et al, 2015), a type of cutting and a propagation date (Wiśniewska-Grzeszkiewicz and Podwyszyńska, 2001;Pietrakowski, 2006).…”
