An experiment was conducted to steady the effect of L-Tryptophan and salicylic acid on callus induced on leaf explants of Catharanthus roseus. Callus induction was achieved by culturing true leaves of the plant on Murashige and Skoog (MS) medium supplemented with 0.5 mg /L 2,4-D and 1mg / L Kin. The best medium to maintain callus was MS medium supplemented with 0.5 mg /L 2,4-D and 1.5 mg / L Kin. Different levels added to MS medium for each L-Tryptophan 0,200,300or400 mg /L and salicylic acid 0, 0.5,1or1.5mg /L. The medium supplemented with 30 g/ L sucrose was used as a control. Results showed the medium supplemented with 200 mgL of L-Tryptophan gave the highest quantity of Vincristine reached 48.66 µg/100 fresh weight of callus. MS medium content at the concentration 1 mg L of salicylic acid gave the highest level of Vinblastine recording 50.98 µg/100 fresh weight of callus. While MS medium supplemented with 0.5 mg /L of salicylic acid gave the highest level of Serpentine 24.76 µg/100 fresh weight of callus. The concentrations of active compound derived from plant leaves were much less than the concentrations produced by the callus grown in vitro. The concentration of Serpentine was 0.059 while Vinblastine was 0.183 and the concentration of Vincristine was 0.064.

AbstractMelia azedarach L. is a valuable source of antioxidants and secondary metabolites. This study is a first extensive report about the effect of different serialization protocols and plant growth regulators (PGRs) on explant disinfection efficiency, callus induction and secondary metabolites production and accumulation in callus cultures of M. azedarach L. In this regard, the effect of plant growth regulators on callus induction and secondary metabolites production were examined. In addition, different sterilization agents were evaluated for disinfection of chinaberry leaf explants. The results showed that the lowest percentage of explant contamination and browning with the highest percentage of callus induction and callus growth obtained with explants pretreated with benomyl (2 g/L) for 2 h and sterilized with 7% H2O2 for 10 min and NaOCl 2% (without pH adjustment) for 12 min. Although adjusting the pH of NaOCl to pH  = 7 and 10 significantly reduced the microbial contamination and increased the percentage of contamination-free cultures of M. azedarach L., adversely influenced the explant viability and callus induction and growth. The highest percentage of callus induction obtained on the MS medium containing 3 mg/L NAA/2,4-D and 1 or 3 mg/L Kin/BAP, and the highest callus yield (1804.833 mg/explant) belonged to the MS medium supplemented with 5 mg/L 2,4-D and 5 mg/L Kin. The callus cultures grown on the MS medium supplemented with 3 mg/L NAA and 1 mg/L Kin produced the highest amount of Quercetin (2.06 mg/g fresh weight), Rutin (5.56 mg/g fresh weight) and Kaempferol (1.84 mg/g fresh weight).

Catharanthus roseus is containing anticancer alkaloids vincristine and vinblastine as is an important medicinal plant. Several studies have conducted on in-vitro culture of this plant. To optimize the somatic embryogenesis, a factorial based on CRD experiment with 10 replications was conducted. Root, hypocotyl and leaf explants grown in-vitro were transferred and cultured on MS media containing different combinations of 2,4-D, NAA and 2,4-D×BAP. The results revealed that in callogenesis, the interaction effects of root and hypocotyl explants×2,4-D and NAA as well as hypocotyl×(1 mg l-1 NAA+1 mg l-1 BAP) was superior than other treatments (p≤0.01). For calli fresh weight, hypocotyl×NAA and hypocotyl×(1 mg l-1 NAA+1 mg l-1 BAP) was the treatment of choice (p≤0.01). The calli produced were sub-cultured to attain the pre-embryos and somatic embryos. For the number of pre-embryos and somatic embryos; the interaction of hypocotyl×2,4-D was the best and most efficient treatment. Seemingly, the production of somatic embryos is accessible in this plant by the logical management of growth regulator combinations. Furthermore, the production and genetic engineering of the somatic embryos could be a promising trend in the subsequent production of high-valued metabolites from this plant.

This study examined the efficiency of callus induction on optimum concentrations of NAA (a-naphthaleneacetic acid) and BAP (6-benzyladenine) from culturing stem and leaf explants of finger eggplant (Solanum sp.) and investigated the phytochemical constituents of callus tissue. Seeds were sterilized by using 3 and 5 % Clorox solution, which gave the highest number of survival seeds (100 %) and were grown in vitro plantlets. The highest frequency of callus induction (100.00 ± 0.00 %) was obtained from stems and leaf explants that were excised from in vitro plantlets. The stem explants cultured on MS medium consisted of 1.0 mg/L NAA + 1.0 mg/L BAP, giving the maximum mean callus fresh weight (0.14 ± 0.05 g). Meanwhile, the leaf explants cultured on MS medium consisted of  0.5 mg/L NAA + 2.0 mg/L BAP, generating the maximum mean callus fresh weight (0.48 ± 0.10 g). The highest frequency of callus induction (88.00 ± 1.60 %) was obtained in solidified MS medium supplemented with 0.5 mg/L NAA + 2.0 mg/L BAP, producing the maximum mean fresh weight of callus (1.54 ± 0.27 g) and dry weight (0.90 ± 0.01 g). The results of the Phytochemical screenings of callus and dried leaf extracts indicated the presence of alkaloids, flavonoids, terpenoids, and saponins.

Baru (Dipteryx alata Vog.) is a species with great economic and environmental potential; it has popular acceptance, besides being a very productive species. Alternative propagation methods are important for species maintenance and exploration. Thus, micropropagation emerged as an alternative technique, providing genetic stability and the production of a large number of seedlings. The aim of the present investigation was to develop a callus induction protocol for in vitro baru explants. The tested explants were nodal, internodal and foliar segments. The explants were disinfected for 30 seconds in 70% alcohol (v/v) and 2 minutes in sodium hypochlorite (1.25% active chlorine). This was followed by triple washing. The inoculation was carried out in test tubes containing 15 mL MS medium (30 g L-1 sucrose, 6 g L-1 agar and 100 mg L-1 ascorbic acid) supplemented with 2.0 mg L-1 naphthalene acetic acid (NAA). The solution also contained 0.0, 2.5 or 5.0 mg L-1 of 6-benzylaminopurine (BAP) with the pH adjusted to 5.8. In the incubation phase, the explants were cultured for seven days in the dark and then subjected to a photoperiod of 16 hours (43 µmol m-2 s-1) at 25 ± 2 °C. The treatments were studied with 2.5, 5.0, 7.5 or 10.0 mg L-1 BAP additions to the MS. Callus formation, contamination and oxidation evaluations were undertaken. The results obtained when using 2.0 mg L-1 NAA concluded that such a treatment should be used to induce callogenesis from nodal explants, while for the tested baru leaf explants, the best results for callus formation were given by the combination of 2.0 mg L-1 NAA with 2.5 mg L-1 of BAP to.

The experiment was conducted to investigate the combined effect of different plant growth regulators and charcoal supplementation in MS medium on growth and development of plantlets regenerated from protocorm like bodies (PLBs) of hybrid orchid. The combination of BAP + NAA, BAP + IAA, BAP + IBA, and IAA + IBA at different concentrations with charcoal supplementation was studied. The result revealed that the use of different growth regulators had significant effect on different parameters studied. The maximum weight of PLBs (5.123 g) was obtained from the combination of BAP + IBA at 1.0 mg/l each. The highest shoot height (3.239 cm) and maximum number of rooted plantlets (4.473) was obtained from 1.0 mg/l each of BAP + NAA combination. The maximum number of leaves (3.490) and the maximum length of leaves (1.946 cm) were obtained from 1.0 mg/l each of BAP + IBA and the highest leaf width (1.166 cm) was obtained from 0.5 mg/l BAP +1.0 mg/l IBA combination. The highest root length was obtained from 0.5 mg/l each of BAP + IAA and the maximum number of regenerated plantlets (20) was obtained from 0.5 mg/l IAA + 1.0 mg/l IBA combination. However, the maximum fresh weight of single shoot (0.219 g) and the maximum number of roots per plantlet (6.300) was obtained from 1.0 mg/I each of IAA + IBA combination.
