AbstractAn effective in vitro protocol for rapid clonal propagation of Echinacea purpurea (L.) Moench through tissue culture was described. The in vitro propagation procedure consisted of four stages: 1) an initial stage - obtaining seedlings on Murashige and Skoog (MS) basal medium with 0.1 mg L−1 6-benzylaminopurine, 0.1 mg L−1 α-naphthalene acetic acid and 0.2 mg L−1 gibberellic acid; 2) a propagation stage — shoot formation on MS medium supplemented with 1 mg L−1 6-benzylaminopurine alone resulted in 9.8 shoots per explant and in combination with 0.1 mg L−1 α-naphthalene acetic acid resulted in 16.2 shoots per explant; 3) rooting stage — shoot rooting on half strength MS medium with 0.1 mg L−1 indole-3-butyric acid resulted in 90% rooted microplants; 4) ex vitro acclimatization of plants. The mix of peat and perlite was the most suitable planting substrate for hardening and ensured high survival frequency of propagated plants. Significant higher levels were observed regarding water-soluble and lipid-soluble antioxidant capacities (expressed as equivalents of ascorbate and α-tocopherol) and total pnenols content in extracts of Echinaceae flowers derived from in vitro propagated plants and adapted to field conditions in comparison with traditionally cultivated plants.

Achyrocline satureioides is a shrub native from South America. In popular medicine it is used in infusions such as digestive, carminative, antispasmodic, eupeptic and emmenagogue. However, its main use is as an ingredient in the liquor industry. Commercial exploitation is carried out through the collection of natural populations in an unsustainable way. The micropropagation of A. satureioides will allow its massive propagation and it will settle a base for its domestication. For this, a clone denominated as M1-5 was first propagated by cuttings. Subsequently, nodal segments obtained from young stems were disinfected by a standard method and cultured on MS medium. These shoots were used as a source of explants for subsequent assays. For its in vitro establishment MS medium and WPM were tested. Once the culture was established, the responses of the explants to increasing concentrations of 6-benzylaminopurine (BAP) (0.0; 0.5; 2.5 and 5.0 μM) with and without 0.05 μM α-naphthalene acetic acid (NAA) on WPM as basal medium were studied during 35 days. The proliferation of buds, the presence of callus and the number and length of the roots were evaluated. All of the “macela” cuttings in vivo propagated rooted and developed satisfactorily under the conditions tested. The application of 5.0 μM BAP alone generated the best multiplication rate, so it was selected as the multiplication medium. De novo shoots rooted spontaneously and finally, transferred to the greenhouse. Here in it was possible to establish a micropropagation protocol not only for the production of plantlets of selected clones but also for the application of biotechnological tools in the development of A. satureioides germplasm.

The influence of growth regulators, explants and their interactions on in vitro shoot bud formation from callus was studied in <I>Dianthus caryophyllus</I> L. The leaf and internode explants were cultured on Murashige and Skoog (MS) medium containing different concentrations of growth regulators. The highest callus induction was observed with 2 mg/l 2,4-dichlorophenoxy acetic acid (2,4-D) and 1 mg/l benzyl adenine (BA). Out of twenty seven shoot regeneration media tested, only 2 mg/l thidiazuron (TDZ) and zeatin alone or in combination with naphthalene acetic acid (NAA) and/or indole acetic acid (IAA) could differentiate calli. The highest average number of shoots was observed with 2 mg/l TDZ and 1 mg/l IAA. Significant differences were observed in calli producing shoots and number of shoots per callus in the explants of leaf and internode. The shoots were elongated and multiplied on MS medium supplemented with 1 mg/l BA and solidified with 1% agar. The shoots were rooted and hardened with 76% survival success in pots after six weeks of transfer to the pots.

Digitalis trojana Ivanina is a member of the Plantaginaceae family and known by its common name, Helen of Troy foxglove. It is perennial endemic to Çanakkale and Balıkesir, northwestern Turkey. In order to develop an efficient shoot regeneration protocol, the leaf explants of D. trojana were cultured on Murashige and Skoog (MS) medium containing 6-benzyl adenine (0.1, 0.5, 1.0, 3.0, 5.0 mg/L) and α-naphthalene acetic acid (0.1, 0.5, 1.0 mg/L), 3% (w/v) sucrose and 0.8% (w/v) agar. The highest number of regenerated shoots was obtained from leaf explants that were cultured on MS medium with 3.0 mg/L BA+0.1 mg/L NAA. Regenerated shoots were rooted on MS medium without plant growth regulators. Rooted plants (2–3 cm) were separately transferred to pots containing a mixture of peat and perlite (2:1 v/v) and acclimatized successfully in a growth chamber.

The experiment was designed to evaluate the effect of growth regulators on leaf explant of Gerbera for callus induction. Various kinds of plant growth regulators such as 6-Benzylaminopurine (BAP), α-Naphthalene acetic acid (NAA), 2, 4-Dichlorophenoxyacetic acid (2, 4-D), Indole-3-acetic acid (IAA) were used to initiate cultures. These were added to Murashige and Skoog medium in different combinations and concentrations. Leaf explants cultured on MS medium supplemented with BAP+ 2, 4-D+ IAA in T4 treatment & BAP+ 2,4-D in T5 treatment showed the best results for callus induction. On the other hand callus was induced early in the combination of BA+ 2,4-D + IAA hormone in T5, T9 & T8 treatment respectively. The rate of callus induction was very low in BA + NAA combinations but it was much earlier.

Abstract The present study reports an efficient in vitro propagation system for Turnera ulmifolia using nodal segments as explants. Turnera ulmifolia (Passifloraceae) is an important garden plant with multipotent medicinal values. Effective shoot proliferation was achieved on agar gelled MS medium (Murashige and Skoog, 1962). The maximum number of shoots (8.3 ± 0.57) per initial explant was obtained on MS medium supplemented with 8.88 mM of 6-benzylaminopurine (BAP) and 0.54 mM of α-naphthalene acetic acid (NAA). The highest number of shoots (59.5 ± 2.10) proliferated on semi-solid MS medium (with agar) augmented with 2.22 mM of BAP and 2.32 mM of kinetin (Kin) along with 0.54 mM of NAA. Longer (4-5 cm) and healthy shoots were rooted (12.0 ± 0.10 roots per shoot) on half-strength MS medium fortified with 9.84 mM of indole-3 butyric acid (IBA). The in vitro regenerated plantlets were hardened in the greenhouse and transferred to the field. Significant developmental changes were observed in the foliar micromorphology of in vitro raised plantlets when these were transferred to the field. The stomatal index was gradually reduced (26.72 to 21.25) in the leaves from in vitro to field environments. But, vein-islets and veinlet terminations (13.4 and 7.6) were increased (39.7 and 18.4) respectively from in vitro to in vivo grown plants. Simple, unicellular, less frequent and underdeveloped trichomes were observed with the leaves of in vitro plants but fully developed trichomes recorded in the field transferred plants. The study could help in understanding the response and adaptation of tissue culture raised plantlets towards changed environmental conditions.

In vitro seed germination and seedling development of Phaius tancarvilleae (L’Her.) Blume. was carried out on 0.8%(w/v) agar solidified MS Medium (Murashige and Skoog, 1962) without hormones or supplemented with different concentration and combination of Naphthalene acetic acid (NAA) and 6-benzylaminopurine (BAP). MS medium supplemented with 0.5 mg/l of BAP was the most ideal condition for early seed germination, protocorm formation and development of seedlings. Germination started after 7 weeks of culture and complete seedlings were obtained after 24 weeks of culture. This protocol might be helpful for mass propagation of orchids by asymbiotic seed germination.

AbstractThymus persicus (Ronniger ex Rech. f.) Jalas is a valuable and endangered natural source of antitumor pentacyclic triterpenoids, i.e., betulinic acid, oleanolic acid and ursolic acid, which grows in northwest Iran. As the plant has a low propagation rate in nature, a suitable method for in vitro-propagation is needed. With the aim of identifying a suitable system for regenerating T. persicus via direct organogenesis, Murashige & Skoog (MS) medium supplemented with different plant growth regulators (PGRs) was tested. In vitro-grown shoot tips were exposed to the cytokinins 6-benzylaminopurine (BAP), kinetin (KN), and thidiazuron (TDZ), alone or in combination with the auxins 1-naphthalene-acetic acid (NAA), 2,4-dichlorophenoxyacetic (2,4-D), indole-3-butyric acid (IBA) and indole-3-acetic acid (IAA). The highest shoot formation (7.1 ± 0.9) was obtained with a medium fortified with 8.9 μM BAP plus 2.7 μM NAA. Regenerated shoots were easily rooted on the different tested media, with the most abundant (16.6 ± 1.4) and strongest roots obtained on half-strength MS medium containing 2.5 μM IBA. The rooted plantlets were successfully acclimatized (76.6%) in a greenhouse before transference to natural conditions. Homogeneity and phytochemical productivity of the in vitro regenerated plantlets were confirmed by random amplified polymorphic DNA (RAPD) profiles and high performance liquid chromatography (HPLC), respectively.

This study aimed to establish a simple and efficient in vivo multiplication protocol by leaf cutting to satisfy the supply of young succulent ornamentals Pachyveria pachytoides and Sedum morganianum. The regenerability of leaves injected with 6-benzylaminopurine (BAP) and α-naphthalene acetic acid (NAA) in vivo were tested with common leaf cutting as control. Results showed a 100% shoot induction frequency using hormone-injeceted methods for the two species. The number of shoots per leaf of 4.0 or 6.0 mg l −1 BAP and 0.1 mg l −1 NAA injected in vivo (5.08-5.14 in P. pachytoides, and 6.22-6.74 for S. morganianum) were significantly greater than that of the other treatments. Since the h ormone-injected leaf cutting needs no aseptic operation which is necessary for in vitro multiplication, it is simple for the commercial production of the two species. The new in vivo propagation method would be of great interest for growers and breeders of succulent plants.

An efficient protocol is outlined for rapid and mass micropropagation of Ficus carica L. (fig). Shoot tips (5 mm) were obtained from mother plants stock grown on half strength Murashige and Skoog (½ MS) medium with the addition of 30 g/L sucrose. For shoot multiplication Benzyl amino purine (BAP) and kinetin produced differences number of new shoot per plant and shoot height. BAP at 0.4 mg/L in combination with 0.2 mg/L indole-3-butyric-acid (IBA) produce maximum in vitro propagation rate, with 4.2 shoots per ex-plant. Root initiation was experimented on MS medium containing different concentrations of mg/L, IBA, IAA (Indole-3-acetic-acid) (IAA) or Naphthalene acetic acid (NAA). Highest number of root (4.3) was resulted when 1.5 mg/L IBA was used. After acclimatization in a mixture of (1 soil: 1 perlite: 1 peat) survival rate of 80% was achieved. For in vitro conservation of F. carica was experimented as microshoots were stored for 40 weeks on MS medium containing different sucrose concentration. Medium supplemented with 3% sucrose gave the highest regrowth (89%) at 24 ± 2 °C. Culture grew slowly when transferred to new fresh medium after the storage periods.
