“…Carra et al [23], from unfertilized ovules of two C. spinosa selected genotypes, obtained the best results (100% of rooted explants) when explants were dipped for 10 min in 50 µM IBA solution, whereas, in a successive work [24], with a mature plant of a Sicilian caper genotype, they found that IBA, NAA, and IAA stimulated the formation of roots from nodal explants but reported the best result in terms of a high percentage of rooted shoots (93.7%) with the synthetic phenylurea 2,3-MDPU (1 µM). Attia and coworkers [30], using axillary buds of wild C. spinosa plants, observed that the highest percentage of the average number of rooted shoots (56.7%) was obtained with 1.5 mg L −1 NAA. In another Capparis species, such as C. decidua, best rooting was achieved on a medium supplemented with IBA (1 mg L −1 ) [16], but in a subsequent work of the same authors [31] 1.0 mg L −1 IBA combined with 0.5 mg L −1 IAA was considered better, whereas Deora and Shekhawat [15] found that 60-70% of the shoots rooted when pulse treated with 100 mg L −1 IBA.…”

The in vitro rooting of three caper (Capparis spinosa L.) selected biotypes, grown in a commercial orchard on the Sicilian island of Salina (38°33′49” N), was performed using—as base material for rooting experiments—shoot explants proceeding from two different in vitro culture systems: solid medium and liquid culture in a PlantForm bioreactor (TIS). The regenerated shoots of each accession were submitted to different auxin treatments (NAA, IBA, IAA - 1 or 2 mg L−1; NAA+IBA 0.75 and 0.25 mg L−1, respectively), supplemented with sucrose or fructose (mg L−1). The highest rooting rate in terms of root percentage (67%) was reached with the explants of the selected accession ‘Sal 39’ proceeding from liquid culture in PlantForm and induced in the MS medium with sucrose, as a carbon source, supplemented with NAA 0.75 mg L−1 + IBA 0.25 mg L−1, after six days in a climatic growth chamber at 25 ± 1 °C in the dark and then placed under a cool white fluorescent lamp, with a PPFD of 35 μmol m−1 s−1 and a photoperiod of 16 h. On the other hand, poor rooting rate was generally achieved under all the tested experimental conditions with the other biotypes, ‘Sal 37’ and ‘Sal 35’, demonstrating the strong role exerted by the previously adopted proliferation method and by the genotype for successful caper in vitro rooting.

“…One of the ways to conserve plant matter is by slow growth in culture media, a method of ex situ conservation that reduces the plants' metabolism, by chemical and/or physical modifications in the medium or culture conditions (AL-ABDALLAT et al, 2017;ATTIA et al, 2018;MUÑoZ et al, 2019).…”

ABSTRACT: Slow-growth tissue culture allows in vitro conservation of plant genetic resources and is a complementary technique to conventional preservation methods. The objective of this study was to evaluate the effect of the culture medium supplemented with sucrose, mannitol and sorbitol osmotic agents on the induction of in vitro slow growth of A. cearensis, seeking to establish alternative techniques for ex situ conservation of the species. Plants with age of 10 days were inoculated in woody plant medium (WPM) supplemented with different concentrations of sucrose (87.64, 131.46, 175.28 or 262.92 mM) combined with mannitol or sorbitol at varying concentrations (0.0, 43.8, 65.73, 87.64 or 131.46 mM), solidified with 0.7% agar. The following parameters were evaluated: survival percentage, number of senescent leaves, aerial part length, root length, aerial part dry mass, root dry mass; and number of shoots. The conservation of A. cearensis was viable for up to 300 days in WPM supplemented with 262.92 mM of sucrose or the combination of 87.64 mM of sucrose with 43.80 mM of mannitol, because besides achieving a survival percentage greater than 55.0%, the plants conserved in these media presented normal development and the best appearances, with predominance of uniform green leaves during the storage process.

Can the Caper (Capparis spinosa L.) Still Be Considered a Difficult-to-Propagate Crop?

et al. 2021

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.
