The effect of the nutrient solution concentration on potato plant growth and minituber yield were determined in a sand closed hydroponic system. Minitubers and micropropagated plantlets of the cv. 'Macaca' were used. Treatments were five nutrient solution concentrations at electrical conductivities (EC) of 1.0 (T1), 2.2 (T2), 3.4 (T3), 4.7 (T4) and 5.8dS m-1 (T5). The split plot randomised experimental design was used with three replications. Plants from minitubers produced higher fresh and mean weight of minitubers, shoot dry mass and leaf area index than the micropropagated ones. However, hi

The on-farm performance of more than 150 000 pre-basic potato (Solanum tuberosum) minitubers of 1–10 g was monitored over two years in contrasting environments in Nepal. Average minituber productivity (grams of basic seed produced per minituber planted) was 171 g in the southern plains and 116 g in the hills. Although the performance of minitubers varied between environments, minituber sizes and potato varieties, the overall results clearly indicated that minitubers can be successfully multiplied by small-scale farmers. This technology therefore allows for the highly decentralized production o

Aeroponics is a modern and soilless technology that is used for the efficient production of pre-basic seed potatoes, namely minitubers. This study aimed to evaluate the effects of the cultivar and type of planting material on the production of minitubers in the aeroponic facility in Guča, Serbia, at short, 7-day harvest intervals. Although aeroponic cultivation prolonged the vegetative cycle in all five investigated cultivars, the dynamics of minituber formation varied between genotypes. Two early maturing cultivars, Cleopatra and Sinora, quickly completed the vegetative cycle and formed a sma

Two field trials were conducted in the Dominican Republic to determine the influence of in-row distances on ‘Granola’ potato (Solanum tuberosum) minituber yield and economic returns. Seedlings generated from in vitro microtubers were transplanted in open-field raised beds at in-row distances of 0.20, 0.25, 0.30, 0.35, and 0.40 m to compare their minituber yield. In-row distances affected potato minituber weight and number per hectare and per plant. Increasing in-row distances from 0.20 to 0.40 m produced a significant decline on minituber weight per hectare (from 12.6 to 8.7 t·ha−1, respective

Potato seed production by conventional methods represents a sizeable investment that, when passed on to farmers, can decrease their profit margins. Potato minitubers produced by aeroponic systems are space- and cost-efficient, and they also provide healthy propagules to be used by farmers. We evaluated the effects of different misting nozzle types, with and without an antidrip feature, and spray direction on potato minituber yield using the Federal University of Viçosa (UFV) Aeroponic System.

Potato (Solanum tuberosum L.) is one of the most valuable crops in the world, ranked as the 4th most important food crops after rice, wheat and maize.

The production of minitubers using the hydroponic method has become an important component in the production of seed potatoes in developed countries. The objective of the study is obtaining minitubers (Prebase), free from diseases, from the transplantation of vitroplants on industrial substrate and different hydroponic systems. The hydroponic culture involves growing plants on artificial substrates, or in a sterile, porous substrate with a high-water permeability.

Aeroponics is a modern farming technology for soilless potato cultivation that enables the efficient production of high-quality pre-basic seed potatoes (minitubers). In this system, the roots and underground stems (stolons) of the potato plants grow within closed modules, suspended in a fine mist of a nutrient-rich solution that continuously recirculates. This setup enables the formation of numerous minitubers with a length greater than 10 mm during the growing period.

Unlike most flowers and fruit, some potato (Solanum tuberosum L.) cultivars can produce anthocyanin-pigmented tubers without direct exposure to light. This study used minitubers developing on in vitro cultured potato plants to study the effect of light on the regulation of anthocyanin and flavonoid biosynthesis in tubers. Although some potato cultivars produced anthocyanin in the dark, light enhanced the production of anthocyanins, other flavonoids and phenolic acids in all cultivars studied.

A total of 46 cultivars were evaluated for quantitative and qualitative carotenoid composition in different growing seasons, locations, storage conditions and disease symptoms. Factors controlling carotenoid accumulation were also tested by developing an in vitro minituber system as a new high-throughput model system for carotenogenesis in potato tubers. Tuber flesh colo

Abstract Seed potato is the starting point in the potato (Solanum tuberosum L.) production chain. In order to secure potato production in a variety of production conditions, plant diseases must be controlled and the yield characteristics of the used cultivars ensured. In addition, production must be cost-effective. Characteristics particular to northern production conditions include long periods of daylight and a short growing season as well as a several months long seed potato storage period.
