Opis:: Various explants from 30-day-old seedlings of Centaurium erythraea Rafn were evaluated for their morphogenetic capacity under in vitro culture conditions. Shoot formation from shoot tip explants was achieved mainly through adventitious bud differentiation. The highest number of shoots (up to 43.3 ± 2.2 from a single shoot tip) was obtained on Murashige and Skoog medium (MS) supplemented with indole-3-acetic acid (IAA) (0.57 μM) and 6-benzylaminopurine (BAP) (4.4 μM). Adventitious shoot regeneration was also achieved through organogenesis from calluses obtained from hypocotyls, cotyledons, roots and leaves on MS medium containing IAA (2.85 μM) and BAP (0.88 μM). Significant differences were noted between explant types in their effects on shoot regeneration. In the primary culture, the best response was obtained either from calluses derived from roots or leaves (44.4 ± 4.5 and 40.2 ± 6.0 shoots per callus, respectively). The number of subcultures of inoculated calluses affected both the multiplication rate (the number of shoots/explant) and shoot morphology (the frequency of shoot hyperhydricity). Shoots rooted with the frequency of 94-100% after culture on MS medium without growth regulators. Plantlets were successfully acclimatized (97%) under high relative humidity and then moved to the greenhouse.

Opis:: Shoot tips excised from shoot culture of Salvia officinalis were encapsulated in 2% or 3% (w/v) sodium alginate and exposed to 50 mM calcium chloride for complexation. Immediately or after 6, 12 or 24 weeks of storage at 4°C, the synthetic seeds were cultured for 6 weeks on half-strength MS medium supplemented with indole-3- acetic acid (IAA) (0.1 mg/l) and solidified with 0.7% agar. The frequency of shoot and root emergence from encapsulated shoot tips was affected by the concentrations of sodium alginate and additives in the gel matrix (sucrose, gibberellic acid, MS nutrient medium) as well as duration of storage. The frequency of shoot and root induction of non-stored synthetic seeds was highest with shoot tips encapsulated with 2% sodium alginate containing 1.5% sucrose and 0.5 mg/l gibberellic acid (GA3). Shoot tips maintained their viability and ability to develop shoots even after 24 weeks of storage when they were encapsulated in 3% alginate with 1/3 MS medium, sucrose (1.5%) and GA3 (0.25 mg/l). Root formation tended to decrease with storage time. Overall, 90% of the plantlets derived from stored and non-stored synthetic seeds survived in the greenhouse and grew to phenotypically normal plants. This procedure can enable the use of synthetic seed technology for germplasm conservation of S. officinalis, a plant species of high medical and commercial value.

Opis:: The aim of this study was to evaluate the influence of sucrose concentration in the preculture medium, as well as the duration of osmotic dehydration on the efficiency of chrysanthemum ‘Richmond’, ‘Lady Orange’ and ‘Lady Salmon’ cryopreservation by encapsulation-dehydration technique. For all cultivars tested, the best regrowth of cryopreserved shot tips was recorded with 0.25 M sucrose concentration and 10 µM ABA during a two-week preculture, followed by a 4- or 7-day osmotic dehydration. The survival rate ranged from 56.8–58.0% (the Lady group) to 63.6% (‘Richmond’). However, the ability to grow was smaller and reached 18.2–50.7%. It was found that higher sucrose concentration during the preculture slowed the growth of chrysanthemum shoot tips and led to an increased formation of multiple shoots (by activating axillary buds) or deformed adventitious shoots (incapable of further growth). The frequency of tissue hyperhydricity also increased, while the rhizogenesis efficiency decreased when higher sucrose concentration in the preculture medium was applied. The influence of osmotic dehydration duration on the explants morphogenetic response was cultivar-dependent.
