“…There are many factors that aff ect rooting, such as accurate control of moisture, temperature, light, hormone formulation and concentration, media, and stock plant quality. For example, light intensity (Park et al 2011) and plug cell size (Park et al 2010) aff ect rooting of rose (Rosa hybrida L.) cuttings, and even the production of rose cut fl owers.…”

Many ornamentals are commercially propagated by cuttings, which is an easy and cost-effective propagation method. Silene L. is a promising genus for extensive use as a landscape ornamental due to its drought tolerance, profuse flowering, and perennial characteristic. Silene is readily cross pollinated, so to ensure genetic purity for breeding and cultivar release, an asexual cutting propagation protocol needs to be established. Adventitious rooting of cuttings of Silene chalcedonica (L.) E.H.L. Krause and Silene coronaria (L.) Clairv. were evaluated using two different propagation substrates and three different root-promoting hormone products. Rooting percentage of S. chalcedonica cuttings was improved by Dip ‘N’ Grow treatment (1,000 mg·L−1), which contains 1% indole-3-butyric acid and 0.5% 1-napthaleneacetic acid, and Hormex Rooting Powder No. 1 (1,000 mg·L−1), which contains 0.10% indole-3-butyric acid; however, 89% of S. coronaria cuttings rooted readily in vermiculite without an auxin treatment. Therefore, rooting success of stem cuttings was highly species related. Because of the relatively low rooting percentage seen in vermiculite (46%) and in perlite (63%) using Dip ’N Grow auxin treatment for S. chalcedonica, an effective stem cutting propagation method still needs to be explored for this species.

Rooting of Tineke and Natal Briar rose stem cuttings in different substrates

The commercial propagation of rose bushes is carried out asexually by the cutting method. The genetic material and the substrate are factors that interfere in the rhizogenic process of the cuttings. Thus, the aim of this work was to evaluate the effect of the substrate on the rooting of cuttings of two hybrid rose bushes. Floriferous branches of matrix plants were cut at the apex and at the base, approximately 8cm long and with two buds, and the basal leaf was removed. The experimental design was completely randomized, in a 2 × 3 factorial scheme (two cultivars, Tineke and Natal Briar × three substrates, carbonized rice husk, coconut fiber and TN Gold®) containing four replicates of 15 cuttings per replicate. The base of the cuttings was immersed for five seconds in IBA 2000mg L-1 solution (indole butyric acid). The cuttings were placed in trays with 24 cells previously filled with substrate and deposited on the floor in a transparent plastic tunnel, built inside a stove. After the 50-day experiment, rootstocks (%), sprouts (%) and dead (%), root length (cm), fresh and dry shoot biomass and roots (g) were evaluated. The rooting percentage of the Natal Briar cultivar was 75%, thus superior to the Tineke cultivar, which had a rooting percentage of 39%. The best substrates for the Tineke and Natal Briar rose cuttings are CAC and coconut fiber, which provided rooting percentages of 81% and 67% of the cuttings, respectively.
