“…Altogether these results clearly confirm, as has already been pointed out [85], that for an individual genotype, or even the same local population, the rate of rooting is strongly determined by the type and concentration of auxin, but, considered as a whole, they also seem to indicate that no one protocol, although optimal with a specific accession, may fit all genotypes [94,96].…”

As a perennial xerophytic shrub, characterized by plesiomorphic features, the caper (Capparis spinosa L.) is naturally spread throughout the Mediterranean basin and occupies an important ecological role, as well as an economic one, in traditional and specialized systems for commercial production. This species, in spite of its wide diffusion, is currently considered at risk of genetic erosion, mainly due to overgrazing and overharvesting for domestic uses and for trade. This situation is made more serious because of the lack of efficient propagation techniques, determining the caper as a “difficult-to-propagate species”. In this review, we report the main available sexual and vegetative propagation techniques with the aim of assessing whether, and to what extent, this criticality is still true for caper as a horticultural crop. In terms of seed propagation, germination rates have generally been considered quite low or unsatisfactory, and are also affected by hybridization phenomena that are likely to occur among both the wild and cultivated forms. The seeds show a physiological dormancy that can be lowered by adopting hormonal treatments, but in situ germination remains a critical phase. Vegetative propagation appears quite effective, mostly as related to in vitro techniques that allow caper cultivation that is no longer affected by propagation for an economic dissemination of the species in more intensive orchards. The research needs for Caper spinosa L. as a horticultural crop, especially in the field of genetic improvement and breeding, are also underlined.

“…However, the main problems associated with vegetative propagation by stem cuttings seem to depend on the type of propagation material, which is influenced by the environment. For these reasons, in recent years, there has been growing interest in micropropagation with the aim of obtaining a large number of genetically homogeneous and uniform plant materials in a limited time and space [ 17 , 18 , 19 ]. In addition, micropropagation techniques can also be employed to study the ecological factors that influence plant development [ 20 , 21 ].…”

The conservation of endangered, rare, and endemic plant species is based on in situ and ex situ conservation strategies. When in situ conservation alone is not sufficient to guarantee the survival of the species, ex situ techniques are adopted in support. This study aimed to develop an efficient micropropagation protocol for Adenostyles by evaluating the effect of different plant growth regulators on leaf explants. Adenostyles alpina subsp. macrocephala (Asterace) is a perennial herbaceous plant endemic to Calabria (Southern Italy). The genus Adenostyles includes three species confined to the mountains of the Mediterranean and southern Europe. For callus induction, media supplemented with different concentrations of Benzylaminopurine (BAP) (0.5, 1, 2, and 3 mg L−1), Naphthaleneacetic Acid (NAA) (1 mg L−1), and 2,4-Dichlorophenoxyacetic Acid (2,4-D) (1 mg L−1) were tested. Shoot regeneration and proliferation were obtained in media supplemented with BAP (1, 2, and 3 mg L−1) and NAA (1 mg L−1). Root induction was obtained in media supplemented with IBA (0.25, 0.50, and 1 mg L−1) and NAA (0.25, 0.50, and 1 mg L−1). Statistically significant differences in callus induction and shoot regeneration were observed between the various media tested. The medium containing Murashige and Skoog (MS) supplemented with 3 mg L−1 of BAP and 1 mg L−1 of NAA showed the highest percentage of callus induction and increased shoot regeneration. The regenerated shoots showed more effective root induction in the hormone-free MS medium and in the presence of Indole-3-Butyric Acid (IBA) at concentrations of 0.25, 0.50, and 1 mg L−1. These results can be used as a basis for the preparation of a micropropagation protocol for different taxa of Adenostyles, as well as other species of Asteraceae specialized to the Mediterranean mountain habitat.

“…Grafting guarantees adaptability to unfavorable pedoclimatic conditions and resistance to telluric pathogens and parasites, but it is costly and labor-intensive, and compatibility problems may arise between graft and rootstock [ 8 , 9 , 10 ]. In-vitro propagation allows the production of a large number of plants in a very short time [ 11 , 12 ]; however, this technique requires equipped laboratories and skilled labor [ 13 ]. Moreover, many woody species are recalcitrant to adventitious rooting from stem cuttings, even if they are micro-propagated [ 14 ].…”

Adventitious root (AR) formation is a key step in stem cutting propagation of economically important woody ornamentals. Inadequate environmental and hormonal conditions can lead to the production of an insufficient or modest number of ARs in stem cutting, with a consequent decrease in quality. The aim of this research was to optimize wild sage and glossy abelia autumn stem cutting propagation protocols, using image analysis to assess the effects of different IBA concentrations and cultivars on AR quality. For both taxa, the treatments were: four IBA concentrations: 0, 1250, 2500 and 5000 mg L−1 and two cultivars: ‘Little Lucky’ (cv1) and ‘Yellow’ (cv2) from Lantana, and ‘Canyon Creek’ (cv1) and ‘Eduard Goucher’ (cv2) from Abelia. Results show that IBA application is not needed to enhance rooting ability; however, IBA concentration is an important factor determining the best overall AR quality in both taxa. In wild sage applying 5000 mg L−1 IBA improved AR quality in ‘Little Lucky’, increasing the root number, total length, surface area and number of forks and crossings, but decreased quality in ‘Yellow’. In glossy abelia ‘Edouard Goucher’, 5000 mg L−1 IBA increased the root number, but 1250 mg L−1 IBA improved AR quality; ‘Canyon Creek’ did not perform as well as cv2 at these concentrations. This study confirms that sensitivity to IBA dosage varies among species and their cultivars. Findings may help the commercial nursery industry produce higher quality cuttings.
