Establishment of tissue culture and acclimatization method for in vitro mass propagation of Echeveria laui and Echeveria elegans

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.

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)

Clonal Multiplication

Vacinium fruits are genetically heterozygous species characterized as “not coming true from seed”. Conventional methods for vegetative propagation of these species, although successful, are slow and labour-intensive, and few propagules can be produced from one plant of a selected clone or hybrid. Micropropagation techniques are important for clonal multiplication, germplasm im provement and gene conservation of Vaccinium fruits cultivated in Canada including blueberries, cranberries and lingonberries. In vitro propagation of these species using axillary bud proliferation and adventitious shoot regeneration has been investigated in a number of studies. Morphogenesis seems to be highly dependent on plant growth regulators and media used for culture, and this dependence is genotype specific. The paper presents the progress in-depth of various aspects of the in vitro culture of Canadian Vaccinium species for their commercial production. Also discussed are techniques for clone rejuvenation and plant tissue culture for mass propagation of Canadian Vaccinium nuclear stocks.

One of the most important applications of plant tissue culture is mass propagation of ornamental plants. This experiment evaluated the effect of different concentrations of NH4NO3 and KNO3 and BAP on the in vitro growth of orchid hybrid Brassocattleya 'Pastoral'. Seedlings of this orchid hybrid were used as explants and cultivated in medium with mineral salts and vitamins from the MS medium (Murashige & Skoog, 1962), with the macronutrients P, Ca and Mg reduced by half, and with an addition of 25 g L-1 of sucrose, 0.1 g L-1 of myo-inositol and 1.5 g L-1 of activated charcoal. Agar-agar was added (6.5 g L-1) and the pH was adjusted to 5.8. As treatments, four concentrations of the NH4NO3 and KNO3 (2x; 1x; ½ and ¼ MS medium) and three concentrations of BAP (0.0; 0.5 and 1.0 mg L-1) were assayed. The multiplication, growth in height, fresh and dry weight and sugar level in dry weight of sprouts were evaluated. There occurred a higher growth in height with 0.25x NH4NO3 and KNO3 salts concentrations of MS medium and higher rate of multiplication with combination of NH4NO3 and KNO3 reduced by half of the MS medium concentration and 1.0 mg L-1 BAP.

Abstract Wetland grasses and grass-like monocots are very important natural remediators of pollutants. Their genetic improvement is an important task because introduction of key transgenes can dramatically improve their remediation potential. Tissue culture is prerequisite for genetic manipulation, and methods are reported here for in vitro culture and micropropagation of a number of wetland plants of various ecological requirements such as salt marsh, brackish water, riverbanks, and various zones of lakes and ponds, and bogs. The monocots represent numerous genera in various families such as Poaceae, Cyperaceae, Juncaceae, and Typhaceae. The reported species are in various stages of micropropagation and Arundo donax is scaled for mass propagation for selecting elite lines for pytoremediation. Transfer of key genes for mercury phytoremediation into the salt marsh cordgrass (Spartina alterniflora) is also reported here. All but one transgenic lines contained both the organomercurial lyase (merB) and mercuric reductase (merA) sequences showing that co-introduction into Spartina of two genes from separate Agrobacterium strains is possible.

Sejauh ini, penelitian perbanyakan somatik embriogenesis baik untuk penyediaan semaian batang bawah maupun varietas komersial jeruk menghasilkan laju multiplikasi yang relatif lambat. Kombinasi antara perbanyakan melalui metode somatik embriogenesis dengan penggunaan bioreaktor, diharapkan mampu meningkatkan laju produksi kalus embrionik menjadi planlet. Kajian awal dilakukan menggunakan nuselus Kalamondin (Citrus mitis Blanco) sebagai sumber kalus. Kalus yang dihasilkan diinduksi dan diperbanyak menjadi kalus embrionik dan embrio dengan cara dikulturkan pada shaker (100 rpm) serta bulb bioreactor. Tujuan penelitian ini ialah membandingkan produksi embrio Kalamondin melalui teknologi somatik embriogenesis pada kultur cair menggunakan shaker dan bioreaktor. Penelitian dilakukan di Laboratorium Kultur Jaringan Balai Penelitian Tanaman Jeruk dan Buah Subtropika, dari September 2008 sampai dengan Desember 2009. Pada tahapan perbanyakan embrio dengan metode shaker, diperoleh bahwa rerata kemampuan kalus menghasilkan embrio dalam kultur selama 10 minggu ialah 18,12 embrio/g kalus. Dengan kisaran waktu yang sama, total embrio yang dihasilkan 3 g kalus/300 cc media cair di dalam bioreaktor menghasilkan 46 embrio/g kalus atau setara 2,53 kali dibandingkan metode shaker. Embrio yang tumbuh pada bioreaktor dapat berkembang hampir 100% menjadi planlet. Hasil penelitian ini membuktikan bahwa aplikasi bioreaktor untuk tujuan perbanyakan massal embrio Kalamondin memiliki pengaruh yang signifikan terhadap laju multiplikasinya.ABSTRAKSo far, research on somatic embryogenesis for rootstock and citrus commercial varieties has been faced by low multiplication rate of embryos. Combination of somatic embryogenesis method and bioreactor hypothezed can increase multiplication rate of embryos and improve regeneration of embryogenic calli to produce plantlets. Kalamondin explants were inducted and proliferated to be embryonic calli and embryos using both shaker (100 rpm) and bulb bioreactor. The aimed of this research was to compare the production of Kalamondin embryos through somatic embryogenesis method on liquid media using shaker and bulb bioreactor. Research was conducted at Tissue Culture Laboratory of Indonesian Citrus and Subtropical Fruit Research Institute from September 2008 to December 2009. Kalamondin nucelus as a callus source was used in this research. Results of the study indicated that the average of embryos production through shaker technique within 10 weeks of culture incubation was 18.12 embryos/g callus, while application of bioreactor imrpoved embryo productivity up to 46 embryos/g calli (3 g/300 cc media). The multiplication rate using the bioreactor increased up to 2.53 fold compare to shaker method. Results of the study give the real evidence that application of biorector for in vitro mass propagation of Kalamondin embryos had high significant effect on embryo multiplication rate.

Colocasia esculenta is commonly known as Taro, it is referred to as cocoyam in Nigeria. They are cherished for their rich taste, nutritional and medicinal properties. Every 100 g of taro corms possess 112 Kcal, 26.46 g carbohydrate, 1.50 g protein, 0.20 g total fat and 4.1g fiber (USDA National Nutrient Data Base). Besides its nutritional value, taro is used as a medical plant and provides bioactive compounds used as an anti-cancer drugs. Traditionally, cocoyams are vegetative propagated from tuber fragments, a practice that encourages pathogen distribution. Colocasia esculenta is a widely distributed food crop in the humid tropics and subtropics. Despite of its wide distribution, Taro plants are commonly infected with DsMV and other pathogens. This virus induces conspicuous mosaic, malformation, dwarfing or feathering on leaves in taro. As the results of infection, it reduces the quality and yield of taro production greatly. This virus is thus considered as a major limiting factor in the production of taro. Here plays the importance of tissue culture plays a major role in producing the disease resistant plants round the year with high quality. For rapid multiplication and production of quality planting materials, tissue culture technology offers promising alternative compared to the traditional production methods.

ABSTRACT An in vitro study has been made of experimentally produced rat ovarian tumours of different age, paying particular attention to tumour reaction to crystallized steroids. Tumours of two histological structures were found: granulosa cell – luteoma tumours and arrhenoblastoma tumours. Both types grew in vitro and pictures of their cell appearance are given. The former type gave the best growth, and the endocrine studies were restricted to this type. The steroids tested (androsterone, oestrone, progesterone) all had an arresting effect in certain cases. This effect is not an unspecific, toxic one. The different tumours react to different extents, some being completely unaffected.
