“…In all the sample sets, the sprouting capacity of the tubers was well-predicted with no difference between the years or cultivars. It is well-known that the physiological age of potato tubers influences the sprouting capacity, and the aging of tubers is accompanied by changes in various chemical components, such as sugar and organic acids (Reust and Aerny 1985). Therefore, a reliable calibration model to estimate the sprouting capacity is considered as a result that NIRS can recognize changes in these components.…”

The potential of near infra-red spectroscopy (NIRS) for predicting the sprouting capacity of potato (Solanum tuberosum L.) tubers was investigated. The experiment was conducted for 2 years using 'Superior' and 'Atlantic' potatoes. A total of 380 potato tubers (200, Superior; 180, Atlantic) weighing 100-200 g were scanned by NIRS, and the sample sets were divided into four groups; three groups were classified based on the cultivars or years as follows: 'Superior', 2004; 'Superior', 2005; 'Atlantic', 2005; the fourth group contained the total number of samples. The reference value for the sprouting capacities was measured by determining the sprout weight after 30 days of incubation at 20°C. The first derivative transformation equation for raw optical data was standardized by applying standard normal variate (SNV) and detrending (DT) algorithms, and calibration equations between them were developed by modified partial least square (MPLS) regression. The coefficient of determination (r 2 ) ranged from 0.868 to 0.965 with a standard error of calibration (SEC) from 0.31 to 0.40 for the calibration sets; r 2 ranged from 0.724 to 0.904 with a standard error of prediction (SEP) from 0.532 to 0.602 for the four validation sets. These results indicate that the calibration model obtained from this experiment is applicable to all the different cultivars for different years, and the NIRS method is a powerful tool for the predictive assessment of the sprouting capacity of potato tubers.

“…Biochemical indicators based on tuber or sprout contents of sugars (Van Es and 4 A Google™ search on "physiological age of seed potatoes and growth vigour" offered 369,000 accessions. Hartmans 1984), enzyme activity (Sacher and Iritani 1982;Van Es and Hartmans 1987), organic acid content (Reust and Aerny 1985), polyamine content (Apelbaum 1984), ATP, ADP, and bound phosphate levels (Biotto and Siegenthaler 1991), and electrolyte leakage (De Weerd et al 1995) have also been used to assess the physiological age of seed tubers. Biophysical indicators include, among other ones, accumulated day-degrees from dormancy break (O'Brien et al 1983) and storage temperature sum (Scholte 1987).…”

As in other crops, yield and quality in the potato is determined by the genotype×environment interaction; limited by seed, crop, and storage management; and reduced by weeds, pests, and diseases. Within the limiting factors, seed tuber quality is crucial, both in low-and high-input crops. If poor seed tubers are used in low-input crops, only low yields can be expected. If poor seed tubers are used in high-input crops, the crops will not take proper advantage of other inputs, such as water, fertilizers, and pesticides applied. At present, physical aspects, such as shape and presence of wounds, seed tuber size, health, and physiological age, are the main components of seed quality, impacting seed vigour. Physiological age is defined as the physiological status of a seed tuber at any time, determined by genotype, chronological age, and environmental conditions from tuber initiation until new plant emergence. This minireview summarizes the physiological age assessment methods and the effects of crop and storage environment and management on physiological age and future crop performance. Possible tactics to reverse physiological age effects are also discussed. More research is still needed to develop a reliable and predictable indicator or index which can relate physiological age to yielding potential.

“…Indicators of the physiological age of potato tubers can also be biochemical. These include the content of sucrose, citric acid, malic acid (Reust and Aerny, 1985), the tetrazolinum test (Sacher and Iritani, 1982), and the electrolyte leakage test (De Weerd et al, 1995). These tests generally show some correlation only with the sprouting of tubers, not with the yield.…”
