“…The anatomical observations in this research have confirmed that Vitis species do not have pre-formed root primordia in their canes, as also stated by Smart et al (2003). They have what is called an induced primordium, which is formed upon a stimulatory effect as wounding by cutting or application of growth regulators (Tailor et al 2022). Initiation of the primordium is usually accounted for the dense cell groups with large nuclei and small vacuoles (Cameron and Thomson, 1969) and in this study vinifera had considerably had more compared to the Vitis hybrid.…”

Understanding the anatomical aspects of adventitious root primordium formation can provide valuable insights into the improvement of propagation techniques, rootstock selection, and overall vineyard management practices in Vitis spp. This work was carried out to investigate anatomical root primordium formation in the rooted cuttings of Cabernet Sauvignon (CS, Vitis vinifera L.) and the rootstock Kober 5BB (Vitis berlandieri x V. riparia) with their relationship to stem anatomy. One-node cuttings were grown under temperature-controlled conditions for 8 weeks. After removal of the roots and calli, the stem parts were fixed in a fixative solution. A revised method of safranin staining was applied to the 90 µm thick cross-sections made with a hand microtome. It was observed that root primordia were derived from the two different regions of the cane tissues: from the groups of cells close to the outside of the conductive tissue system and from the cell groups in the deeper site, close to the pith. Cultivars showed significant differences in terms of the regions where they had their root primordial initials. Number of potential root primordia was statistically higher in CS. Both CS and 5BB had root angles in the range of 83° to 86°. It was concluded that grapevine cuttings had only induced root primordia and the capacity to produce them was dependent on the genotype. Formation and development of root primordia and the anatomical differentiation of the cell groups were similar in Cabernet Sauvignon and 5BB.

“…The actual list of environmental and endogenous factors that affect ARF includes nearly every factor that can affect plant growth and development. Among these, the following have been recognized as potent ARF regulators: Traditional plant growth regulators (auxins, cytokinins, gibberellins, abscisic acid, and ethylene); Light intensity, quality, and photoperiod; Oxygen and carbon dioxide levels; Free radicals; Relative air and soil humidity; The pH and physical properties of the substrate; Antioxidants; Polyamines; Nutrients; Specific growth regulators such as strigolactones, jasmonates, brassinosteroids, melatonin, and generally indoleamines and catecholamines; Hydrogen; Hydrogen sulfide; Methane; Calmodulin; Salicylic acid; Amino acids; Mitogen-activated protein kinase (MAPK); Ca 2+ -dependent protein kinase (CDPK); Cyclic guanosine monophosphate (cGMP) and others [ 1 , 32 , 36 , 43 , 44 ]. …”

“…At the same time, the wounding induced at the base of the cutting due to its severance from the mother plant enhances the activity of NR, resulting in increased NO production [ 43 ]. There is increasing evidence in recent years strengthening the role of NO in adventitious root formation, as it has been shown to promote rooting in Arabidopsis, cucumber, mung bean, marigold, Eucalyptus grandis , chrysanthemum and other plant species [ 33 , 58 , 69 , 73 , 74 , 75 ].…”

“…Cytokinins, on the other hand, are known to inhibit ARF [ 12 , 22 , 43 ]. According to Tailor et al [ 43 ], cytokinins may downregulate the action of NO, thus suppressing its positive impact on ARF and in the end the cutting’s rhizogenesis.…”

“…Another possible plant growth-regulating compound, melatonin, which is an indolamine sharing a common precursor with the natural auxin IAA, i.e., the amino acid tryptophan, has been found to promote ARF in several plants [ 65 , 80 , 81 ]. Melatonin seems to be implicated in auxin and NO signaling pathways, resulting in elevated concentration of both while at the same time enhancing the rooting potential and even more strengthening the role of NO in ARF [ 43 ].…”

Adventitious root formation is defined as the formation of new roots on above-ground plant parts and is considered crucial for the survival of a plant under harsh environmental conditions (i.e., flooding, salt stress, and other abiotic stresses) as well as in the nursery industry. Clonal propagation is based on the ability of a plant part to grow and generate a completely new plant, genetically identical to the mother plant, where the plant part came from. Nurseries exploit this potential by multiplying millions of new plants. Most nurseries use cuttings to achieve that, through the induction of adventitious root formation. Many factors have been implicated in the capacity of a cutting to root, with the major role being played by auxins. During the last few decades, intense interest has emerged in the role of other potential rooting co-factors, such as carbohydrates, phenolics, polyamines, and other plant growth regulators, as well as signal molecules, such as reactive oxygen and nitrogen species. Among the latter, hydrogen peroxide and nitric oxide have been found to play significant roles in adventitious root formation. Their production, action, and general implication in rhizogenesis are discussed in this review, in terms of interaction with other molecules and signaling.

Identifying characteristics of invasive species or growth forms that facilitate their range expansion is critical for management. Clematis vitalba L. (old man's beard) is an invasive temperate liana in many areas of its introduction, yet its seedlings do not thrive in circumstances where resources are limited. Although some lianas in both tropical and temperate climates have been shown to spread by clonal stems along the ground, the bulk of previous research on C. vitalba reproduction has focused largely on aspects of seed ecology. The vegetative growth of the species is poorly understood. The first objective of our study was to evaluate the use of vegetative spread by C. vitalba as a means of local dispersal and population growth. We excavated ten 1‐m2 plots in infested riparian zones and found an extensive, branching network of creeping stems, both above and below ground. Our second objective was to test the ability of C. vitalba stem fragments to act as vegetative propagules. After 4 months, ~50% of two‐node fragments had regenerated, from both creeping and climbing stems. These studies help explain how a temperate liana forms populations and dominate ecological communities. The findings provide good evidence that C. vitalba may rely quite heavily on asexual reproduction. In addition, the results document liana stem phenotypic plasticity; fragmented climbing stems are just as likely as fragmented creeping stems to reprogram shoot tissue systems, generate roots and regrow as independent plants.
