Slow growth rate of plantlets, few micro-shoots per explant, and slow root growth rate are restrictions of in vitro propagation of poinsettia (Euphorbia pulcherrima Willd. ex Koltz). The purpose of this research was to develop an efficient in vitro proliferation technique for poinsettia ‘Prestige™ Red’. Explants (apical buds and axillary buds) placed on Murashige and Skoog (MS) basal medium containing only 6-benzylaminopurine (BA) and combinations of BA and indole-3-acetic acid (IAA) mostly produced red callus, which is productive and some white and gray–green calluses at the base of plantlets after 1 month, whereas explants in a medium without plant growth regulators (PGRs) produced no callus. Addition of IAA into the rooting medium increased rooting efficiency; plantlets grown in half-strength MS salts and vitamins with 28.5 μM IAA initiated rooting 11 days earlier than the plantlets grown with no PGRs. Optimization of PGR concentrations during poinsettia micropropagation helped resolve previous restrictions of in vitro poinsettia proliferation. Chemical names used: 6-benzylaminopurine (BA); indole-3-acetic acid (IAA)

Simple Sequence

In recent years, the awareness of pomegranate health benefits has grown exponentially; nonetheless the existing propagation methods remain a challenge to supply adequate suitable planting materials needed for commercial production. Micropropagation can lead to mass production of plantlets and callus-mediated in vitro regeneration can open avenues for the use of genetic engineering to improve this crop. The aim of this study was to evaluate appropriate conditions for pomegranate micropropagation, callogenesis and use Simple Sequence Repeat markers to screen for somaclonal variation. Cytokinins (Benzylaminopurine, Kinetin and Thiadiazol-5ylurea) were tested for shoot induction from nodal explants while auxins (1-Naphthaleneacetic acid, Indole-3-butyric acid and Indole-3-acetic acid) were tested for root induction of in vitro regenerated shoots. 1-Naphthaleneacetic acid combined with Benzylaminopurine was assessed for their ability to induce callus from cotyledon and leaf explants. Genetic integrity between mother plant, callus and in vitro regenerated shoots were assessed using eight Simple Sequence Repeat markers. Maximum number of shoots and leaves were obtained on full strength Murashige and Skoog media with 6.9 &micro;M kinetin. The highest number of roots was achieved on half strength Murashige and Skoog media with 4.9 &micro;M Indole-3-butyric acid and the longest root was got on half strength Murashige and Skoog media with 5.3 &micro;M Indole-3-acetic acid. Leaves and cotyledons demonstrated to be potential explants for callus formation at all hormonal combination levels tested. Eight out of 13 amplified alleles were polymorphic. A wider genetic variation was found with similarity coefficient range of 0.46-0.92. More somaclonal variation was in regenerated shoots compared to callus.

Shoot multiplication of a putative variant of Catharanthus roseus (L.) G. Don, was achieved in vitro using shoot tips and nodal segments as explants. The addition of growth regulators to establishment medium stimulated bud breaking and shoot elongation. The maximum shoot multiplication (15.1 shoots/microshoot) and the longest shoots (7.0 cm) occurred on Murashige and Skoog medium (MS) containing 1.0 mg L-1 of N6-Benzyladenine (BA) and a- Naphthalene acetic acid (NAA). All microshoots formed roots and normal root morphology occurred on half strength MS salt supplied with 0.5 mg L-1 NAA or Indole-B-Butyric acid (IBA). Rooted microshoots (95 %) were successfully transferred to soil.

 The immature seeds of Dendrobiumchryseum, asympodial epiphytic orchid with yellow flowers, were cultured in vitro, and the resultant protocorms were used as explants for seedling development. Protocorms were cultured on½ M.S. medium fortified with Kinetin (Kn), 6-Benzylaminopurine (BAP), and Gibberellic Acid (GA3) in three concentrations (0.5mg/l, 1.0mg/land 2.0 mg/l) both alone and supplemented with 5% and 10% coconut water (C.W.). The highest number of shootsofD. chryseum developed on ½ - M.S. medium fortified with 2.0mg/lofKn and10% C.W. and the longest shootsdeveloped on ½ M.S. media fortified with 1.0mg/lGA3, and 10% C.W. The shoot derived from protocorms were placed in ½ M.S. medium fortified with three different rooting hormones, Indole -3- acetic acid (IAA), Indole -3-butyric acid (IBA) and α-Naphthalene acetic acid (NAA) in different concentrations alone as well as with each 1.0mg/l hormone combined with 10% C.W. The most effective of these media was ½ M.S. medium fortified with 1.5 mg/l IAA for rooting as well as for the production of longest roots. The present study could be useful for standardizing the protocol for mass propagation of the endangered orchid Dendrobiumchryseum.

Symbiotic Seed Germination

Pholidota articulata is an epiphytic orchid mostly used in ornamental cut/pot flower and in traditional medicine. As it has high ornamental and medicinal values, its population from natural habitats is decreasing, therefore, it is listed in the Appendix-II of Convention on International Trade in Endangered Species (CITES). The objective of the present study is to obtain the in vitro plants of P. articulata from seed culture to conserve its germplasm. The in vitro seed germination was carried out in different strengths of Murashige and Skoog (MS) and Knudson C (KnC) medium supplemented with various plant hormones. On the half-strength of MS medium, seeds were started to germinate after 4 weeks of primary culture and they were developed into protocorms with first leaf primordium earlier than on the other medium. Therefore, in vitro developed protocorms were sub-cultured on the half-strength of MS medium supplemented with different concentrations of 6-benzylaminopurine (BAP), gibberellic acid (GA3) and α-naphtalene acetic acid (NAA). They were successfully developed into shoots on the 1.5 mg/l BAP supplemented half-strength of MS medium. Later, they were inoculated on the half-strength of MS medium supplemented with different concentration of α-napthalene acetic acid (NAA), indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) for the root formation, where IBA supplemented medium was found effective for the development of roots. Thus, this study provides a reliable protocol for non-symbiotic seed germination and plant production, and reveals that seed-derived protocorms are good explants for the in vitro mass propagation for conservation and sustainable utilization in horticulture.

Disinfected midrib sections of Mussaenda `Queen Sirikit' ≈3 to 4 mm in size were cultured on a basal medium of Murashige and Skoog salts and vitamins, 87.7 mm sucrose, and 5 g Sigma agar/liter supplemented with several concentrations of indole-3-acetic acid (IAA) (0, 5.0, 10.0, 20.0 μm) and 6-benzylaminopurine (BAP) (0, 0.5, 1.0, 2.5, 5.0, 10.0, 25.0, 50.0 μm). Cultures were subculture onto the same treatment after 5 weeks and observed weekly for 15 weeks for the presence of somatic embryos. As somatic embryos were produced, they were subculture onto basal medium supplemented with 0.5, 1.0, 2.5, or 25.0 μm BAP. Callus was first observed at 2 weeks in cultures grown on basal medium supplemented with 5.0–20.0 μm IAA and 0–50.0 μm BAP. Somatic embryos were observed at 8 weeks on basal medium supplemented with 5.0–10.0 μm IAA and 2.5–5.0 μm BAP. Callus cultured on 0–10 μm IAA and 5.0–10.0 μm BAP produced the greatest number of somatic embryos by 15 weeks. Somatic embryos subculture to basal medium supplemented with 25.0 μm BAP proliferated shoots, while eliminating BAP from the medium resulted in root and callus production. Shoots and entire plants were removed from in vitro conditions and successful] y acclimated to greenhouse conditions. Somatic embryo-derived plants flowered sporadically 25 to 35 weeks after removal from in vitro conditions. Variations in sepal number and leaf number per node were observed at 1% to 5%.

Somatic embryos were induced on the roots of Camellia japonica L. plantlets regenerated from an in vitro clone of juvenile origin. The embryos appeared to differentiate from epidermic cells and to be connected with the root via a few parenchymatous cells. Somatic embryogenesis occurred on basal medium and with or without various combinations of zeatin, BA, and IBA. Secondary embryos were induced on cotyledons and/or hypocotyl regions of somatic embryos. Two morphological types of somatic embryos were developed, seed-like and bud-like types, and their formation was influenced by the presence of BA in the medium. Embryogenic capacity has been maintained for more than 24 months by subculturing secondary embryos at 7- to 8-week intervals. The best gibberellin/auxin combination for inducing the germination of isolated somatic embryos was GA at 5 mg·liter-1 G A3 and IAA at 1 mg·liter-1. P1antlets were successfully established in planting medium and have continued to grow in a greenhouse.
