Abstract The woody shrub, Itea virginica L., Virginia sweetspire, has recently increased in popularity due to its multiple seasons of interest in the landscape. In this study, we investigated micropropagation as a means to produce this plant. Combinations of BA (1, 4, and 10 μM) and NAA (0.01, 0.1, and 1.0 μM) were evaluated for in vitro shoot induction in Itea virginica L. ‘Henry's Garnet’ on a Murashige and Skoog medium. The best combination of BA and NAA (4 μM and 0.1 μM) yielded an average of 7.9 microshoots per explant for ‘Henry's Garnet’. When dipped in a common auxin-containing, commercial rooting formulation, microshoots rooted ex vitro within four weeks. Tissue-culture produced plantlets of I. virginica ‘Henry's Garnet’ flowered one year after removal from culture.

Pandoreas, Australian natives of horticultural significance, were successfully propagated using tissue culture. A protocol for rapid in vitro multiplication of commercial cultivars was developed using nodal segments cultured on Murashige and Skoog medium containing either BA or kinetin. Maximum shoot induction and number of shoots per explant for P. pandorana (Andrews) Steenis and P. jasminoides (Lindley) Schumann were on 8.8 μm BA and 4.6 μm kinetin. Higher levels of cytokinin in the medium inhibited shoot formation. Tissue-cultured shoots were rooted with IBA. This study demonstrates that Pandoreas can be successfully micropropagated. Chemical names used: 6-benzylaminopurine (BA); 3-indole butyric acid (IBA).

Background: Humic substances plays a vital role in the plant tissue culture as a growth hormone for in vitro propagation of many plant seedlings. The aim of this study was to investigate the effect of added humic-fulvate complex (HFC) at the various concentrations on the growth and development of grape seedlings in in vitro at the different nutrient levels. Methods: The cutting of khasansky grape were cultivated on ¼ Murashige and Skoog medium or ½ Murashige and Skoog medium either alone or supplemented with the humic-fulvate complex at the different concentrations at (0.1, 1 and 10 ml/l). Then, they were cultured for 4 weeks under a controlled environment. Result: The data observed that the low concentration of Murashige and Skoog medium (¼ MS) for in vitro rooting of grape cv. ‘Khasansky’ either alone or combined with HFC at the various concentrations significantly increased the rooting percentages and the total length of roots and stimulating the rate of vegetative growth compared with cultivated in ½ MS medium either alone or with supplemented with HFC. ¼ MS+ 10 ml/l HFC was the best treatment for improving the growth of khasansky grape seedlings.

Tissue culture of plants has many applications, from producing genetically identical horticultural varieties, to production of secondary metabolites, to virus indexing, and most relevantly, developing novel traits by genetic transformation. Using Agrobacterium-mediated transformation on somatic embryos, blight-resistant American chestnuts [Castanea dentata (Marsh.) Borkh.] have been developed as shoot cultures in plant tissue culture. Rooting tissue-cultured shoots and acclimatizing the rooted plantlets are key steps in tree production. In this study, in vitro and ex vitro rooting methods were compared. The ex vitro method resulted in a lower initial rooting percentage but an overall higher survival percentage, resulting in higher potted plant production. The higher survival was likely due to partial acclimatization taking place before the plantlets were transplanted into potting mix. After 8 weeks, plantlets rooted via the ex vitro method were taller, and had more, and larger, leaves than the in vitro-rooted plantlets. These trees are currently in high demand for inoculation studies for federal regulatory review and eventually for restoration of this keystone species to its native habitat.

Leaf discs from 15 mutant clones of tomato were tested for their morphogenetic response in Murashige and Skoog medium supplemented with 12 combinations of the growth regulators napthaleneacetic acid (NAA) and benzylaminopurine (BA) and 4 combinations of NAA and zeatin. The results show that either callus, shoots, roots, or shoots and roots can be produced depending upon the hormone concentrations and ratios. Plants were regenerated from 12 of the 15 varieties tested.

Mass Propagation

An efficient mass propagation method for Feronia limonia was developed from excised shoot tips and nodal explants of in vitro grown seedlings. Explants were cultured on MS medium with different conc. of NAA, Kn, IAA and BAP singly or in combinations. Highest number of micro shoots and better plant growth were obtained from these two explants on MS medium supplemented with 0.2 mg/l BAP alone. The regenerated shoots were successfully rooted on MS medium supplemented with 0.5 mg/l NAA. The in vitro raised plantlets were successfully established in soil following the formation of roots with 100% survivability under ex vitro condition.

Summary. A number of commercially available cultivars of Scaevola aemula, S. albida, S. phlebopetala, S. striata and material collected from the wild of S. glandulifera, S. hookeri and S. ramonissima were successfully propagated by tissue culture. Shoot segments 3–4 cm in length were multiplied in Murashige and Skoog medium without hormones. Addition of 25–150 µmol kinetin/L in the micropropagation medium of S. aemula and S. phlebopetala resulted in the formation of deformed shoots. Tissue cultured shoots rooted in hormone-free medium in 4–6 weeks. Indole-3-butyric acid (10–20 µmol/L) had an effect on rate of root initiation of S. phlebopetala but not on percentage of rooting. A high survival percentage (>95%) was obtained when plants were transferred to soil under glasshouse conditions indicating that micropropagation of Scaevola is feasible.

Mature seeds of Bauhinia variegata L were cultured on half strength Murashige and Skoog medium. For experimentation, nodal cuttings were used as explants from in vitro growing plants. Cytokinin, N-benzyl-9-(2-tetrahydropyranyl) (BPA), kinetin(6-furfurylaminopurine), zeatin, 6-(4-hydroxy-3-methyl-trans -2-butenyl amino purine), 2- isopentenyl amino purine (2-ip), and benzylaminopurine (BAP) were tested for best propagation. Well grown plants were achieved in medium supplemented with 5 µM BPA and 0.5 µM BAP. The propagated plants were acclimatized very well after transferred to the field.

This study aimed for knowing and obtaining the best concentration of kinetin and NAA interaction effects in influencing the shoot induction, knowing how the plant growth regulators in induction mediastill affect the shoot additionin the MS0media and also knowing the largest number of roots in rooting media for shallot by in vitro. The experiment was conducted at Laboratory of Tissue Culture Seed Technology, Faculty of Agriculture, Padjadjaran University, during January 2011 until May 2011. This experiment divided in 3 stages, namely shoot induction stage, shoot subculture to MS0 media stage and shoot subculture to rooting media stage. Experimental method used in the shoot induction stage was factorial Completely Randomized Design with three replications. The first factor was the kinetin with four levels,0, 1, 2, and 3 mg L-1. The second factor was the NAA with three levels, as 0, 0.01, and 0.1 mg L-1. Basic media used for each treatment was MS. The experiment result showed there was an interaction between kinetin and NAA on shoot induction stagewith the plantlet height, leaf number, and shoot addition. The best result for leaf number was gained from interaction with 2 mg L-1 kinetin without NAA,while the treatment of 2 mg L-1 kinetin with 0.01 mg L-1 NAA gave a better interaction for theshoot addition variable.
