“…In most studies, older seed potatoes produce more main stems (Iritani, 1968;Iritani & Weller, 1987;Knowles & Knowles, 2006), whereas in the studies by Ezekiel (2004), seed potato age had no influence on stem number. The timing of the temperature sum accumulation increases the number of stems in seed potato (Bodlaender & Marinus, 1987;Jenkins et al, 1993), whereas the growing season temperature and daylength do not influence the numbers of seed potato stems or bulk stems (Johansen, Lund, & Nilsen, 2002;Johansen & Nilsen, 2004). In the present study, naturally maturated seed potatoes produced the most bulk stems and roots and showed physiological behaviour similar to old seed potato.…”

“…Studies show that physiologically older seed potatoes emerge more quickly than the younger ones (O'Brien et al, 1983;Bodlaender & Marinus, 1987;Van der Zaag & Van Loon, 1987;Knowles & Botar, 1991;Jenkins, Gillison, & Alsaidi, 1993;Essah & Honeycutt, 2004;Eremeev et al, 2008). Particularly in short growing season production areas, the quick emergence of seed potatoes accelerates early development of potato growth.…”

In the present study effects of production history on tuber sprout, root, stem development and crop yield of seed potato cultivars Fambo and Van Gogh were investigated in the High Grade Area of Finland (64.9 N, 25.4 E). The haulms of seed potatoes were destroyed at the time of flowering (50 days after planting, DAP), three weeks after flowering (75 DAP) and as a control the haulm was left to natural death until harvest (95 DAP). The temperature sum accumulation of the seed potatoes was recorded for the growing season and storage period. In addition, the use of plant hormone gibberellic acid (GA) in sprout control was also investigated.The results indicated that cultivar properties had a greater effect on the sprouting and crop yield of seed potatoes than production-phased haulm killing or temperature sum accumulation. Haulm killing carried out at three weeks after flowering (75 DAP) accelerated the emergence of both cultivars significantly compared to killing at 50 DAP or 95 DAP. Gibberellic acid (GA) treatments significantly increased the number of sprouts and at lower concentration (100 mM) GA increased the number of tubers in the cultivar Fambo. Thus, the timing of haulm killing and in the case of Fambo, GA treatment influenced the characteristics of seed potatoes produced in the present study, revealing methods to improve seed potato production in the northern latitudes.

“…The physiological age of tubers increases with increasing storage duration (Krijthe, 1962: Bodlaender & Marinus, 1987) and is affected by conditions and treatments during tuber growth (Krijthe, 1962;van Ittersum & Struik, 1992) and during storage and presprouting (O'Brien et al, 1983: van Ittersum et ai., 1993). …”

SummaryThe production of large volumes of vitroplantlets and greenhouse tubers for increasing the rate of multiplication at the start of seed programmes provides the opportunity of reducing the total number of field generations grown before the seed moves into commerce. This implementation is especially useful for countries where high quality potato seed tubers cannot be produced because there are no vector-free production areas.This review covers the lollowing steps: a) laboratory production of microplantlets and microtubers: b) minituber production in the glasshouse: c) storage and dormancy of micro-and minitubers: d) field performance of micro-and minitubers compared with conventiomd seed tubers: e) incorporation of the mentioned propagules in seed production systems.Many optimized protocols are already available for propagating plantlets, inducing microtubers and obtaining minitubers in the glasshouse at all periods of the year. Advanced molecular approaches techniques (RFLP and RAPD) to detect genetic variation in the progeny of these propagules have been described. Investigations carried out in this field have shown genetic stability, with the propagulcs usually reproducing plants true-to-type and tubers without deviants. By contrast, variations were demonstrated in DNA extracted from old suspension cell cultures. Field trials assessed a lower yield potential crops from in vitro propagules compared with conventional seed tubers, mainly due to slow early crop development and the failure of plants caused by early stress after emergence. This may cause problems when the growing season is short because of the necessity for planting late to avoid night frosts and the mandatory haulm killing dates, common in many seed producing areas. Strategies for improving the lield performance of micro-and minitubers are discussed. The most promising crop husbandry techniques appear to be: a) using tubers of a suitable physiological age. properly presprouted and encapsulated: b) optimizing the time application of fertilizer and irrigation, and c) using floating films.Outside the classical seed tuber areas of Northern Europe where the length of the growing period for prc-basic seed is usually not more than 80 days. the growing season is long enough to obtain reasonable yields even from micro-and minitubers.

“…Seed-tuber physiological age, a somewhat subjective measure ofthe developmental status of a tuber, is a major factor in determining the number and vigor of shoots produced upon sprouting. Indeed, seedtuber age influences all stages of daughter plant growth, from sprouting to final yield (2,3,6,7 (10,11). The length of the incubation phase is temperature dependent, with low temperatures prolonging it and higher temperatures accelerating it (5).…”

Studies were conducted to characterize the effect of advanced potato (Solanum tuberosum L.) seed-tuber age on plant growth potential and whole-plant morphology. Plant growth from singleeye seedcores from 5-to 18-month old 'Russet Burbank' seedtubers was compared. Loss in apical dominance was apparent with advanced age. On a per-core basis, the amount of plant dry weight was equal for the two ages at 30 days from planting. However, individual plants from older cores displayed reduced shoot, root and leaf dry weights, leaf area, and leaf number. These effects reflected altered dry-matter partitioning and contributed to an overall change in plant morphology with advanced age. On a total seedcore basis, relative growth rate of plants from older seedcores was greater than that from younger seedcores over the 30 day growth interval. Leaf area ratio was also greater for plants from the older seedcores; however, unit leaf rate was not affected by tuber age and plants from both young and old seedcores assimilated dry matter at the same rate. Age-induced differences in growth indices reflected differences in the degree of plant differentiation over the interval of study. Treating younger seedcores with 1-naphthaleneacetic acid (NAA) prior to planting inhibited overall plant growth. In older cores, NAA stimulated root growth, restored apical dominance, decreased leaf number per plant, and increased average leaf area per leaf. In short, NAA altered the morphology of plants growing from older seedcores to more closely resemble that of plants growing from younger seedcores. While auxin significantly altered plant form, vigor of plants from older seedcores was not fully restored by auxin treatment, indicating that age-reduced vigor of potato seed-tubers is not solely mediated by auxin.Early sprout vigor significantly influences yielding ability of potato (Solanum tuberosum L.) (17). Seed-tuber physiological age, a somewhat subjective measure ofthe developmental status of a tuber, is a major factor in determining the number and vigor of shoots produced upon sprouting. Indeed, seedtuber age influences all stages of daughter plant growth, from sprouting to final yield (2,3,6,7 (10,11). The length of the incubation phase is temperature dependent, with low temperatures prolonging it and higher temperatures accelerating it (5). Hence, a given physiological age can be produced by manipulating storage temperature and/or length of the storage period.Many of the age-induced alterations in potato plant growth appear to be auxin related. For example, treatment of 20-month-old potato seed-tubers with auxin decreased the number of stems produced per seedpiece and increased the average tuber size and total yield (9). With advancing age, the loss in apical dominance is first evident between eyes on the tuber, and eventually multiple sprouts are produced within each eye. Auxin may play a key role in the regulation of apical dominance in many plants (18). Thus, sprouts developing from aged seed-tubers may have a reduced ability to synth...
