Potato (Solanum tuberosum L. ssp. tuberosum) microtubers were produced in vitro with Liquid Lab TM Rocker system. A thin-layer liquid culture was applied together with a regular pitch in autoclavable simple plastic vessels. All cultures were carried out at room temperature without contamination problems. Each cultivar tested (Asterix, Timo, Van Gogh, Velox) formed microtubers in the Liquid Lab system. The mean number of microtubers per vessel (50 explants) varied between 30 (cv. Asterix in 8 weeks tuber induction) and 75 microtubers (cv. Velox in 11 weeks tuber induction). Majority (63%) of the microtubers was sufficient by size and weight (above 200 mg) for further storage at dormancy (4°C). The cv. Velox yielded the highest number of microtubers with cultivation capacity. As a result of prolonged microtuber induction of 2-3 weeks, more microtubers with competence for cultivation were obtained per cultivar, except for cv. Van Gogh. Still, the mean weight of Van Gogh microtubers was significantly higher after prolonged microtuber induction (0.67 g) than after short induction (0.51 g). In conclusion, Liquid Lab TM Rocker system is a novel, efficient and rapid system for mass propagation of potato.

“…0.12 g) tended to desiccate under field condition, and were more susceptible to disease. Park et al (2009) noted microtubers less than 0.5 g lost moisture content more rapidly than larger ones. Wiersema et al (1987), using microtubers with an average weight of 0.63 g, found total tuber yield increased with increased size.…”

Tuber yield of plants from three sizes of in vitro produced microtubers were compared to yields of plants from three sizes of greenhouse produced minitubers of Nicola and Russet Burbank. Microtubers were: small-size, 0.2-1.5 g; mid-size, 1.5-3.0 g; and large-size, >3.0 g. , and small-size minitubers gave the lowest tuber number, 409,375 tubers/ha −1. Regarding tuber yield, the type of tuber did not influence either cultivar. Nicola was influenced neither by type nor by size of tubers. Russet Burbank, however, was sensitive to size of tubers, especially, within minitubers. Large-size mini and microtubers were the most productive, 49 and 40 t ha −1

“…However, potato crops are susceptible to viral and fungal infections, resulting in yield loss and crop quality deterioration (Chen et al, 2018). The production of virus-free microtubers in sterile environments may reduce the risk of viral infection (Park et al, 2009). The morphogenesis of potato plantlets and the subsequent growth of microtubers are influenced by light (Halterman et al, 2016).…”

Monochromatic light and wide-band white light both affect plant growth and development. However, the different effects between monochromatic light and addition white light to monochromatic light on the formation, growth, and dormancy of microtubers have not been fully explored. Therefore, we evaluated these effects using in vitro potatoes grown under pure blue and red lights and a combination of blue light and red light supplemented with white light, respectively. Current results suggested that light spectra influenced microtuber formation, growth, and dormancy by regulating potato plantlet morphogenesis, affecting the synthesis and transportation of photosynthetic metabolites, and altering the accumulation and distribution of biomass in various plant tissues. Monochromatic lights and the combined spectra had differing effects. For instance, monochromatic red light induced the growth of more microtubers, whereas addition white light to red light decreased number but increased weight of microtubers. Meanwhile, monochromatic blue light facilitated tuber growth, whereas addition white light to blue light decreased microtubers weight but increased microtuber number. In addition, composite lights of addition white light to monochromatic red and blue lights both extended the dormancy period, and monochromatic blue light shortened the dormancy period of microtubers >300 mg. Therefore, in microtuber agricultural production, specific light conditions may be applied at different growth stages of in vitro potatoes to increase the number of effective microtubers (>50 mg) and to satisfy storing requirement of seed microtubers.
