“…The physiological age of a seed tuber plays an important role in determining subsequent crop performance, influencing tuber yield and quality through its effects on emergence, canopy cover development and duration, number of stems, tuber initiation, bulking rate and duration, the number of tubers per stem, and tuber size distribution, as summarised by Struik and Wiersema (1999). Extensive research into the effects of physiological age on crop growth has predominantly compared the planting of physiologically younger and older seed tubers (Kawakami 1963;Iritani 1968;Perennec and Madec 1980;Reust 1982;Moll 1985;Allen and O'Brien 1986;Vakis 1986;Bodlaender and Marinus 1987;Van Loon 1987;Benz and Fahem 1988;Hay and Hampson 1991;Botar 1991, 1992;Struik et al 2006;Oliveira et al 2017;Mediouni et al 2020). Commonly observed patterns indicate that plants developing from physiologically older tubers exhibit earlier emergence, faster initial growth rate, earlier tuber initiation, more stems, reduced foliage, and earlier senescence, making physiologically older seed tubers suitable for shorter crop cycles than physiologically younger seed tubers.…”

The physiological age of potato seed tubers influences the subsequent field performance of the crop, conditioning its growth and development. This study investigates the effects of the physiological age of seed tubers on the field performance of four contrasting, currently widely grown cultivars (Agria, Festien, Innovator, Lady Claire) across three sites in the Netherlands over 3 years (Cycles 1—3). Seed tubers were produced annually at a single site under uniform conditions, with variations in physiological age induced by applying different storage temperatures (4, 7, 10, and/or 17 °C). Our previous study revealed varying effects of storage temperature on sprouting behaviour among cultivars, suggesting different rates of ageing. After completing the storage season, in the current study these seed tubers were planted in the field and subsequent crop performance was thoroughly phenotyped. Cultivar-specific effects of storage temperature were evident during early growth stages and when seed tubers were stored at 17 °C in Cycle 3. However, within the storage temperature range of 4 to 10 °C, the influence of storage temperatures was small or inconsistent. Overall, effects on canopy cover, stem and tuber number, yield and quality, and tuber yield explanatory variables were limited. The outcomes suggest that while very high storage temperatures should be avoided in regions with long crop cycles, stringent cold storage regimes are unnecessary to achieve optimal growth vigour in potato seed tubers of the studied cultivars in a temperate climate.

This study was carried out in two seasons (2010–2011 and 2012–2013) in Jos, Plateau State, Nigeria to investigate the growth and yield of potato (Solanum tuberosum L.) seed tubers as affected by storage conditions and storage duration. Five potato varieties (“Nicola,” “Bertita,” “Diamant,” “BR63-18,” and “Roslin-Ruaka”) were stored for three durations (12, 24, and 32 weeks) in three kinds of stores (room temperature store [RTS], diffused light store [DLS], and air-conditioned store [ACS]). The experimental design was a split–split plot in a randomized complete block design with the potato varieties, storage conditions, and storage durations as the main, sub, and sub–sub plots, respectively. All the parameters assessed varied with variety except the plant height. Germination and establishment were significantly higher in ACS than in RTS and DLS. RTS and DLS resulted in more aboveground stems than ACS. Storage in ACS resulted in a significantly higher plant height, leaf number, total number and yield of tubers, and yield of saleable tubers in both seasons. Seed tubers stored for 24 weeks resulted in the highest establishment count and the mean number of aboveground stems in both seasons. Aboveground stems increased from 12 to 24 weeks of storage and declined at 32 weeks. Seed storage for 12 weeks resulted in the highest total number of tubers, whereas 32 weeks had the lowest number of tubers in both seasons. Seed storage for 12 and 32 weeks resulted in the highest yield of tubers in seasons 1 and 2, respectively. In conclusion, potato varieties varied greatly in the rate of physiological aging; hence, every variety required specific storage conditions and duration for optimal growth and yield.
