Virus Indexing

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.

The intensification of viniculture involves the organization of the virus-tested planting material production, establishment of the basic parent plantings, certification of the virus-tested planting material with the control of genetic stability of the grape plants propagated in tissue culture. The modified nutritional medium was developed for microclonal propagation of vine in vitro with the content of the free amino acids: glycine and glutamine, increasing propagation factor up to 15% and the number of nodes on microplant up to 27%.

Vanilla has a potential to be developed through tissue culture techniques to anticipate the limitations of the parent plant as a source of planting material. The in vitro propagation ability of vanilla shoots needs to be controlled with the regulation of Kinetin and Benzyl Amino Purines. The interests of this study are 1) analysis of the response of vanilla explants at several Kinetin concentrations; 2) analysis of the response of vanilla explants at several concentrations of BAP and 3) analysis of the interaction of Kinetin and BAP on the response of vanilla explants to form shoot multiplication. The research was conducted at the Tissue Culture Laboratory Politeknik Negeri Jember from June to December 2020 using a factorial Completely Randomized Design (CRD). Factor 1 was the Kinetin concentration of 0.0, 1.0, 2.0 mg.L-1 and the second factor was the concentration of BAP 0.5, 1.5, 2.5 mg.L-1. The results proved that the fastest shoot multiplication occurred on MS medium + Kinetin 2 mg.L-1 with a mean of 8.7 days after inoculation. The mean number of shoots was 7.6 shoots/explant with the highest average wet weight of 0.9 grams/explant at the addition of BAP 1.5 mg. L-1 at measurement 70 days after inoculation.

Ginger is most important cash crop of the hilly region of Nepal. However, availability of disease free planting material (rhizome) is the major problem faced by Nepalese farmers. Tissue culture is the only option to produce disease free rhizome of ginger. Suitable culture media combination is most important for the production of planting material in ginger through tissue culture. Therefore, effect of different level of sucrose and growth regulators on micro-propagation of ginger was studied using local collection ‘Kaski Local’. Early stage bud was used as explant. MS basal media with different level of sucrose and growth regulators was used as tissue culture media. 30 g/L sucrose, 30 g/L sucrose+5mg/L BA, 30 g/L sucrose+5 mg/L BA+0.5 mg/L NAA, 60 g/L sucrose+5mg/L BA, 60 g/L sucrose+5 mg/L BA+0.5mg/L NAA, 90 g/L sucrose+5 mg/L BA was used in this study. The explants were surface sterilized, cultured and incubated at 25±2°C, 90-95% relative humidity and 14:10 hours light:dark photoperiod for 8 weeks. Increased level of the sucrose increased the rhizome weight, however, addition of NAA produced more positive effect for this. MS basal media with 60 g/L sucrose+5 mg/L BA+0.5 mg/L NAA produced higher rhizome weight.Journal of Nepal Agricultural Research Council Vol.3 2017: 45-48

Background: Lilium (Lilium longiflorum Thunb.) belongs to the family Liliaceae and is a native of Northern Hemisphere (up to South Canada and Siberia). Conventionally Lilium can easily be propagated by sexual and asexual methods of propagation but these prevalent methods are not capable of meeting the increasing demand in domestic and global market. Generally, Lilium is propagated through bulbs but, limited number of bulbs per plant, long dormancy period of bulbs which again results into non-availability of planting material throughout the year. Keeping in view the above facts, the present study was undertaken with the following objective: “To standardize the cost effective protocol for micro propagation of lilium to produce disease free and true to type plants at a faster rate”. Methods: The present investigation was carried out in the Tissue Culture Laboratory of the Centre for Research and Application in Plant Tissue Culture. The experiment was laid out in a C.R.D. (Factorial) with three replications. In vitro raised bulblets were separated out and were transferred on to the root regeneration media. Different levels of NAA were used in MS media for the rooting of in vitro raised bulblets and percent rooting of plantlet is recorded. Result: It was interesting to note that the media LR-3 (MS + NAA 1.0 mg/l) is most efficient for rooting in all type of cultivars. All the three cultivars used responded very poor on media LR-1 (MS basal).
