Nauclea Diderrichii

Nauclea diderrichii is a tree species of economic importance. However, its plantation establishment is limited by inadequate seedling production. Hence, there is ample scope of tissue culture for its mass propagation. Its in vitro plantlets development as affected by media strengths indicated that 100 % seed germination was obtained in full MS basal medium while the least (3.35 %) was from quarter-strength at 8 Weeks after inoculation (WAI). The effects of BAP and NAA assessed on the growth of its sub-cultured plantlets showed that highest number of leaves (17) and adventitious shoots (3) were obtained from MS basal medium supplemented with 0.1 mg/l BAP only. Whereas, highest shoot length (3.61 cm) and average number of roots (5/plantlet) were obtained from the same medium without hormone(s) at 8 WAI. Further sub-culturing into MS with 0.05 mg/l NAA resulted into plantlets having optimum shoot and massive root growth ready for acclimatization in 6 WAI. The plantlets were successfully acclimatized using coconuthusk/ topsoil mixture with 90 % survival. Plant Tissue Cult. & Biotech. 31(1): 51-60, 2021 (June)

The aim of this investigation was produced micro tubers of four potato cultivars Premiere, Bintje, Estima and Escort in vitro. Apical meristems (0.2-0.4 mm) of potato cultivars were excised and cultured on nutrient medium and incubated at 24±2 Cº and 1000 lux light intensity for 16 hrs per day. The developing plantlets were examined serological by using ELISA technique to eliminate the viral infected plantlets. The virus-free plantlets were chopped into pieces with single bud and re cultured on fresh medium for mass propagation. For micro tubers formation in test tubes, the cultures were transferred to another medium containing a high percent of sucrose (60g/L) with different concentrations of kinetin; the cultures were incubated under 16±2 Cº and 8 hrs photoperiod. The plantlets formed micro tubers after 8-10 weeks from culturing. The results showed significant differences among cultivar’s in their response to in vitro culture and micro tubers formation. The results also showed that the kinetin concentration had significant effect on micro tubers, and 1mg/l kinetin concentration was the best. The micro tubers were stored for 10 week at 4Cº to break down the dormancy period, and gave 100% germination under nursery condition. Numbers of tubers derived from micro tubers and normal tubers of these cultivars were compared at the end of season.

Tissue Culture Techniques

Pineapple propagation by lateral shoots, suckers or crowns is often confronted with limited number of regenerated seedlings and high diversity in flowering and fruit formation. In order to solve this problem, this study offer an alternative method by using tissue culture techniques. This study aimed to determine the effect of growth regulators on plantlet regeneration from bud slicing of pineapple cv. Tangkit. Four levels of 2.4-D (0.0, 0.001, 0.01 and 0.1 ppm) in combination with BA (0.0, 0.1, 1.0 and 10.0 ppm) were tested on solid MS medium. Cultures were incubated in total darkness for a week followed by transfer to 16-hour photoperiod. Results showed that explants treated with 2,4-D and/or BA succeeded in regenerating adventitious shoots. Average leaf number did not differ significantly among treatments (P = 0.60). Highest leaf number (2.99 ± 0.23) was obtained on medium with 0.01 ppm 2,4-D without BA, followed by 0.1 ppm 2,4-D without BA (2.85 ± 0.33). Meanwhile, roots were only formed on medium with 0.1 ppm 2.4-D without BA (4.2 ± 0.37 per shoot). Thus, complete plantlets were regenerated only on medium supplemented with 0.1 ppm 2,4-D without BA. The growth of plantlets was relatively uniform, and plantlet acclimatization succeeded 100% on Jiffy pots. The finding of optimum concentration of 2.4-D and BA in this study is important to develop standard protocol for in vitro propagation of pineapple cv. Tangkit. Thus, the benefit of producing seeds in large quantities and relatively uniform in growth is made possible through tissue culture technique.

Rauvolfia Serpentina

Rauvofia serpentina Benth. ex Kurz (Apocynaceae) is a highly important medicinal plant growing in the terai belts of Nepal. This plant is facing a high threat from various kinds of poachers in the wild due to improper ways of collection as well as almost no conservation strategy. In the present study, we have identified the way for rapid in vitro multiplication of this species using tissue culture technique as an effective tool for ex situ conservation. In this study, MS medium along with BAP and NAA alone or in combinations at different concentrations have given successful results in producing callus, multiple adventitious shoots both from callus and nodes and multiple roots from both callus as well as nodes. The in vitro as well as ex vitro rooting of the micro shoots have been achieved. The rooted seedlings have been successfully acclimatized. The best media for shoot multiplication from the node and callus cultures have been identified as MS + NAA 0.5 + BAP 0.5 ppm and MS + BAP 2.0 ppm, respectively. For rooting in and ex vitro, NAA has been found to be the best among auxins. For callus induction all the auxins specially NAA 1.0 ppm and 2,4-D 2.0 ppm have been found to be the best.  Keywords: Micropropagation; Rauvolfia serpentina; In vitro rooting; Pulse treatment and acclimatization.   DOI: 10.3126/sw.v6i6.2635 Scientific World, Vol. 6, No. 6, July 2008 58-62

A method for rapid micropropagation of sea kale (Crambe maritima L.) was developed. Petiole explants placed in vitro on a medium containing 0.5 mg/L indoleacetic acid (IAA), 6.0 mg/L kinetin, and 1.5 mg/L benzylaminopurine developed callus within 15 days and shoots within 28 days. Nearly four adventitious shoots could be developed within 3 weeks by placing the initial shoot on media without IAA. To develop roots, the shoots were then transferred to the basal medium containing 0.1 to 1.0 mg/L indolbutyric or α-naphthaleneacetic acid. Rooted plantlets were obtained within 2 or 3 weeks. After an acclimatization period of 6 weeks in a greenhouse in unsterilized medium, the plantlets could be set outdoors.

Factors Affecting

In the present study, an efficient system for the in vitro regeneration of adventitious shoots from the peach rootstock Hansen 536 leaves has been established. Twenty regeneration media containing McCown Woody Plant Medium (WPM) as a basal salt supplemented with different concentrations and combinations of plant growth regulators (PGRs) were tested. Expanded leaves along with their petiole from 3-week-old elongated in vitro shoot cultures were used as starting explants. The highest regeneration rate (up to 53%) was obtained on WPM basal medium enriched with 15.5 μM N6-benzylaminopurine (BAP). The influences on leaf regeneration of the ethylene inhibitor silver thiosulphate (STS) and of different combinations of antibiotics added to the optimized regeneration medium were also investigated. The use of 10 μM STS or carbenicillin (238 μM) combined with cefotaxime (210 μM) significantly increased the average number of regenerating shoots per leaf compared to the control. In vitro shoots were finally elongated, rooted and successfully acclimatized in the greenhouse. The results achieved in this study advances the knowledge on factors affecting leaf organogenesis in Prunus spp., and the regeneration protocol described looks promising for the optimization of new genetic transformation procedures in Hansen 536 and other peach rootstocks and cultivars.
