“…Treatments with exogenous hormones (e.g., 6-BA, NAA, and IBA) are a common method employed to address this problem [31,32], and here we identified 50 mg•L −1 NAA + 50 mg•L −1 IBA + 20 min immersion time as the optimal hormone treatment for boosting rooting rates. In comparison, 1 h in an IBA solution effectively stimulated rooting in cuttings from four olive cultivars [33]. Additionally, the best overall rooting for Gardenia augusta 'Radicans' cuttings was obtained using a foliar spray or basal quick-dip of 123.0 µM IBA + 67.1 µM NAA [16].…”

To guide the cultivation of superior Chinese fir plantlets, we designed an L16(4)4 orthogonal experiment to determine how leaf age and exogenous hormones influence key growth processes in leaf cuttings. Hormone concentration and treatment duration significantly affected leaf cuttings in all three age categories; 6-benzylaminopurine (6-BA), 1-naphthaleneacetic acid (NAA), and treatment time exerted the strongest effects on callus initiation rates. Additionally, NAA had the largest effect on the rooting rate across all cuttings, and all three hormones significantly influenced the bud germination rate. Based on our experimental results, expected optimal treatments for callus initiation were 10 mg∙L−1 indole-3-butyric acid (IBA) for 10 min, 30 mg∙L−1 NAA for 15 min, and 10 mg∙L−1 NAA plus 30 mg∙L−1 IBA for 10 min. For the rooting rate, the expected optimal treatment was 50 mg∙L−1 NAA and 40 mg∙L−1 IBA for 5–20 min. Finally, for bud germination, optimal treatments were 20 min of immersion in water, 30 mg∙L−1 6-BA plus 50 mg∙L−1 NAA for 15 min, and 30 mg∙L−1 6-BA for 5 min. Plantlet formation only occurred in the <one-year-old leaves, and at very low rates (maximum 5.8%); this outcome is likely attributable to the mother plant’s relatively old age (five years). Plantlet formation from cuttings is dependent on ensuring the rooting rate after callus initiation. Therefore, to promote rooting rates and bud germination, we recommend leaving more xylem at the base of leaf cuttings.

“…A pesar de haber presentado un alto porcentaje de germinación superior e inferior, necesarios fisiológica y anatómicamente para el proceso, la formación de raíces fue mínima y, además, no se observó un efecto positivo de la aplicación hormonal en el enraizamiento. La formación de raíces adventicias es una característica genética regulada por la interacción de factores ambientales y endógenos, entre los cuales la fitohormona auxina juega un rol esencial (Pacurar et al, 2014), y la cantidad a aplicar depende de la especie y de la concentración de auxina en el tejido (Inocente et al, 2018).…”

Resumen La investigación se propuso determinar las diferentes respuestas a la propagación vegetativa de tres especies de bambú (Guadua weberbaueri, Guadua lynnclarkiae y Guadua angustifolia) a partir de secciones de ramas. Los factores de evaluación aplicados fueron el número de nudos en la estaca, el efecto de una sustancia hormonal y, como cofactor, el diámetro de la estaca. El experimento se realizó en un propagador instalado en el Instituto

“…The greatest effect on rooting achieved by Auxins (Eid et al, 2018). IBA (indole butyric acid) is the most auxin used for rooting of olive cuttings (Hussein at al., 2017 andShiri et al, 2019), therefore, the results found vary a lot according to the dosage, the cultivar, the period of rooting, the substrate and the type of cutting among other factors.…”

C OLD temperature during winter season consider an environmental constrains for root and shoot development of olive cuttings. This experiment was carried out during two seasons (2018/19 and 2019/20) to study the rooting ability of 'Coratina', 'Picual' and 'Manzanillo' olive cultivars in addition to study the effect of supplementary intermittent application of IBA and antioxidant (1:1 ascorbic and citric acid) at 100, 200, 300ppm three times after cuttings planting on their rooting behavior during cold winter. The results showed that, 'Coratina' olive cultivar recorded the highest significant rooting percent success (75.86 &74.73%) and root number compared to 'Picual' and 'Manzanillo' cultivar. While, 'Manzanillo' cultivar recorded the lowest rooting percent, root number and root length. Antioxidant at 300ppm recorded the highest rooting percent 74.44 & 73.78%, root number and root length. Concerning the interaction effect, the highest significant rooting percent 94.67 & 96.00% and root number was achieved by 'Coratina' olive cultivar treated with 300 ppm antioxidant. While, the highest root length recorded by 'Coratina' cultivar with100ppm IBA and the highest leaves number recorded by 'Manzanillo' cultivar under 100 ppm antioxidant. It can be concluded that, 'Coratina' olive cultivar was more suitable for winter season propagation. Also, supplementary application of 300ppm antioxidant was more effective in olive cuttings propagating, while 300ppm IBA had negative effects.
