Different Responses to Adventitious Rhizogenesis under Indole-3-Butyric Acid and Seaweed Extracts in Ornamental’s Cuttings: First Results in Photinia x fraseri ‘Red Robin’

Agriculture, Journal Year: 2023, Volume and Issue: 13(3), P. 513 - 513

Fraser’s photinia ‘Red Robin’ (Photinia x fraseri Dress, Rosaceae family) is an important primary ornamental landscaping species with optimal hedge or screen effects and low maintenance, but it difficult to root when propagated by cuttings, although high concentrations of phytohormones are used optimize rhizogenesis. To our knowledge, there currently no feasible enhanced method for vegetative propagation through stem using seaweed extract-based biostimulants as promoters. Given the economic importance species, this research aims assess indole-3-butyric acid (IBA) stimulators on quality in terms rooting indicators ground aboveground agronomic features. The treatments applied were different commercial compared untreated control: C0: distilled water; Rhizopon AA: 1% IBA (R1); Kelpak®: 2 mL L−1 (K2); 3 (K3); Goteo®: (G2); (G3). first results showed responses adventitious rhizogenesis under both extract treatments. At 70 DAC (days after cutting), stimulated production over 80% cuttings callus; at 240 DAC, percentage rooted treated R1 was highest = 34.3%; worst obtained biostimulant doses: K3 21.3% G3 20.7%. Furthermore, produced 3.07 roots per cutting, which 50% higher than average all other applications Kelpak® Goteo® biostimulants, concentrations, resulted inhibition length values below control.

Seaweed Extracts as Substitutes of Synthetic Hormones for Rooting Promotion in Rose Cuttings

Horticulturae, Journal Year: 2022, Volume and Issue: 8(7), P. 561 - 561

Published: June 21, 2022

In the horticultural sector, achievement of an efficient and eco-friendly sustainable production plants is nowadays challenging. Indeed, in plant vegetative propagation woody ornamentals, substitution chemical products used to promote rooting cuttings with natural extracts would be a desirable goal. Thus, aim this work was test replacement synthetic phytoregulators, such as auxins brassinosteroids, biostimulants, seaweed extracts, for promotion rose cuttings. The rate biometric parameters control treated distilled water were compared those hormones, i.e., or 22(S),23(S)-homobrassinolide, two commercial based on low temperature Kelpak® Phylgreen. Two scented hybrid tea cultivars assess possible genotype-dependent effects, ‘Michelangelo®’ ‘Cosmos®’. Auxins confirmed their role root growth enhancement ornamental Like these improved survival both cuttings, highlighting its suitability propagation. Brassinosteroids showed species-dependent effect, increasing biomass ‘Cosmos®’ while it resulted ‘Michelangelo®’. Phylgreen did not improve necessity evaluating applicability methodology product before use. conclusions, our results highlighted possibility replace cutting production.

The potential of biostimulants on soil microbial community: a review

Frontiers in Industrial Microbiology, Journal Year: 2023, Volume and Issue: 1

Published: Dec. 13, 2023

To improve agricultural sustainability, an agriculturally productive system is required to maintain soil fertility and reduce the loss of biodiversity. One modern technologies employs microbial biostimulants that create abundant yield with high nutritional values, controlling disadvantages obtained from environmental changes. This review aimed provide knowledge on effects communities’ potential promote production. Plant are novel materials applied in farming sector nowadays crop commonly occur plant seeds as alternative chemical derivative application plants. Microbial function biological inputs increase production decomposition soil. In conclusion, necessitates accomplishment absolute choice beneficial microbes well combat problems will be encountered later sector.

Revealing the Complex Interplay of Biostimulant Applications

Plants, Journal Year: 2024, Volume and Issue: 13(16), P. 2188 - 2188

Some biostimulant products provide proven benefits to plant production, potentially offering more environmentally friendly, sustainable, and natural inputs into production systems. However, the transference predictability of known between different growth environments, application protocols, management systems are fraught with difficulty. In this study, we carried out carefully controlled glasshouse in vitro assays applications humic acids, protein hydrolysates, seaweed extract compare variability effects dosage-dependent variations across diverse conditions, encompassing a sufficient range comprehensively assess their full spectrum impacts. The results demonstrated clear trend each exhibiting significant growth-promoting effect within critical concentration range, but detrimental when fell outside range. While substantial were observed under tended be sensitive generally led negative impacts sterilised conditions. combined use biostimulants mostly resulted toxicological responses only two treatments showing marginal synergistic effects. findings complex interplay conditions plants.

Improving Aerial and Root Quality Traits of Two Landscaping Shrubs Stem Cuttings by Applying a Commercial Brown Seaweed Extract

Horticulturae, Journal Year: 2022, Volume and Issue: 8(9), P. 806 - 806

Published: Sept. 2, 2022

The availability of quality planting material is one the most important requirements for increasing productivity any ornamental crop. Horticulturists make use auxins and apply them exogenously to cuttings generate adventitious roots balanced shoots. Many studies have illustrated influence seaweed extracts on growth crops; their in vegetative cutting propagation, our knowledge, has been little investigated. Moreover, there a lack information IBA extract concentration carbohydrate content. This research aimed compare effects commercial extract, called Goteo®, with that phytohormone IBA, aerial root traits stem two Mediterranean landscaping shrubs: Lantana camara (S1) Abelia × grandiflora (S2). treatments applied semi-hardwood were as follows: C0: untreated control; concentration: 1250 mg L−1; Goteo® concentrations at 1, 2, 3 mL L−1. In L. camara, greatest values rooting percentage obtained under when compared A. grandiflora, no among treatments. presented study shows stimulated provided better shoot development Abelia. S1, treated dose L−1, greater number roots, traits, morphology content, than those IBA. S2, 1 L−1 could be recommended obtain high-quality rooted cuttings.
