“…The significance of phenological stage of shoot on rhizogenesis Rosa ×alba 'Maiden's Blush' was proved in this work (Figures 3-11). The results of this study confirmed that the phenological stage of shoots harvested from stock plants for cuttings was decisive for the successful propagation of the once-blooming roses [1,4,5,7,8,28]. The plant preparations, Bio Rhizotonic, Root Juice™, and Bio Roots, did not show unequivocal impact on the rooting percentage of 'Maiden's Blush' (Figure 3).…”

“…One of the most economic and easy methods of propagation with cuttings is rooting of the single-node leaf cuttings from semi-wood shoots harvested during flowering time [3]. However, the flowering period of the once-blooming roses lasts only three to four weeks, during which the phenological phases transition rapidly [1,2], and research has shown the significance of that factor considering the harvest of the shoots for cuttings [3][4][5].…”

Once-blooming roses belong to difficult-to-root. One-bud leafy cuttings have limited storage capacity, due to the small size of the stem, and are exposed to prolonged stress conditions. The objective of this study was to examine if the treatment of the cuttings of Rosa × alba ‘Maiden’s Blush’ with plant origin preparations as rooting enhancers may increase their rooting percentage, chlorophyll a/b, and proteins concentration in leaves. The cuttings were prepared from shoots in four phenological stages: flower buds closed, flowers open, immediately after petal shedding, and 7–14 days after petal fall. The following were used: 0.4% indole butyric acid (Ukorzeniacz Aaqua), 0.2% naphthalene acetic acid (Ukorzeniacz Baqua), Bio Rhizotonic; Root Juice™, and Bio Roots. Controls included untreated cuttings. The highest rooting percentage was obtained after two treatments with 0.6% Bio Rhizotonic (81.5%), compared to the control (55.0%), using cuttings from shoots with flower buds closed, but the rooting enhancers did not show any unequivocal impact on rooting percentage in cuttings of all phenological stages or affected improvement this feature in cuttings harvested 7–14 after shedding petals with low root ability. However, the action of plant preparations affected positively higher soluble proteins and chlorophyll content. The plant-origin preparations can be used as alternatives to chemicals in nursery production.

“…Monder, Niedzielski, and Woliński () and Monder and Pacholczak () evaluated the potential of biostimulants with hormone‐like activity for improving the viability of shrub rose cuttings. Shrub roses of older origin have a wide range of applications and are valuable for the preservation of biodiversity and historical heritage (Monder & Pacholczak, ). Monder et al.…”

“…() tested three environment‐friendly biostimulants based on seaweed extract (Bio Rhizotonic, Root Juice, and Bio Roots; Table ) and concluded that their use in optimal concentrations increased rooting ability and chlorophyll and protein contents in rose shoots. Monder and Pacholczak () studied whether the phenological phases of rose stock plants and the above‐mentioned biostimulants influenced the rhizogenesis of cuttings and changes in the content of polyphenolic acids. The content of polyphenolic acids correlated with rooting percentage.…”

Different substances from the natural origin which have beneficial effects on plant growth and development, stress resistance, and crop yield and quality can be called biostimulants or biostimulators. Their physiological effects depend on their composition as they contain various organic and mineral compounds which plants can use as metabolites, growth regulators, and nutrients; however, biostimulants cannot be considered biofertilizers. Biostimulants applied in plant production have been widely considered as an environment‐friendly agricultural practice—and so are now among tools used in sustainable agriculture. Here, we discuss the results of the biostimulants’ effect investigations performed in Croatia, focused on horticultural crops, with edible plant species, such as tomato, garlic, bell pepper, lettuce, strawberry, garden cress, and basil, as well as ornamentals, such as wild rose, wax begonia, Mexican and French marigold, moss rose, everlasting flower, common zinnia, English primrose, and scarlet sage. The investigated biostimulants were applied at all plant growth stages, from germination to full plant and fruit or flower commercial maturity, using the seed treatment, foliar application, or irrigation. To evaluate biostimulant effectiveness, various morphological, physiological, and quality traits were analyzed. In this wide array of studies, the evaluated biostimulants mostly enhanced seed and transplant vigor, stimulated vegetative growth, improved nutrient acquisition and distribution within the plant, increased antioxidative capacity of plant tissues, contributing to higher stress tolerance, and improved plant yield and fruit/flower quality. In general, the research reviewed here implies possible benefits of biostimulant application in horticultural production, especially in stressful growth conditions, such as the transplant stage, reduced fertilization, or incidence of other abiotic stress. Considering possible interactions among the contained physiologically active compounds, the effects on plants may depend on dose, time of treatment, growth conditions, and plant species. Therefore, further research of biostimulant applications in horticultural production is suggested.

Some biostimulants, including plant origin preparations, act similarly to plant hormones. Moreover, the supplementation of known and unknown rooting cofactors can stimulate rhizogenesis in cuttings. The aim of this research was to assess the response of difficult-to-root and long-rooting stem cuttings of the once-blooming old variety Rosa ‘Hurdal’ to preparations of plant origin. The hypothesis was that plant origin preparations could enhance rooting processes by inhibiting chlorophyll a/b degradation in leaves and postponing leaf senescence, simultaneously increasing the quality of cuttings. The one-bud stem cuttings were made in four phenological stages: (H1) flower buds closed, (H2) open flowers, (H3) just after petal fall, (H4) 7-14 days after petal shedding. They were treated with either standard commercial powder preparations containing 0.4% indolebutyric acid (IBA) or 0.2% naphthalene acetic acid (NAA) as well as with commercial plant origin preparations that this work will henceforth refer to as: Algae Extract, Organic Preparation, and Plant Extract. The cuttings were evaluated after 12 weeks of rooting them in two substrates: peat-perlite and peat-sand (v:v; 1:1). Mean root percentages for both substrates were noted after preparation from stage H1 (74.5 %), H2 (59.5 %), H3 (50.8 %) shoots. The H4 cuttings didn’t root at all and were not considered further. The means for all phenology stages together were the highest by the use of 0.6 % Algae Extract, 0.012 % and 0.02 % Organic Preparation, 0.2 % and 0.4 % Plant Extract. The lowest means were reported for the control cuttings as well as NAA and IBA treatment. Plant origin preparations encouraged growth parameters but did not unequivocally inhibit the decrease of chlorophyll content in the cuttings’ leaves. Rooting percentage depended on the quality of cuttings as well as chlorophyll a/b and soluble protein content in leaves in both rooting substrates.
