“…Thereafter, scopoletin levels began to fall but in an oscillating fashion. The evolution of scopoletin through time behaves as previously reported (Buschmann et al, 2000;Sánchez et al, 2013;Mahmod & Beeching, 2018). SFW reached maximum levels at the second day of storage in every clone (Figure 3).…”

“…The residual sum of squares remains large. This is not surprising as it is well established that experimental errors associated with PPD studies are high (Mahmod & Beeching, 2018). Also, genetic variation could not be included in this model in spite of evidence of its relevance (Mahmod & Beeching, 2018;Morante et al, 2010).…”

“…This is not surprising as it is well established that experimental errors associated with PPD studies are high (Mahmod & Beeching, 2018). Also, genetic variation could not be included in this model in spite of evidence of its relevance (Mahmod & Beeching, 2018;Morante et al, 2010). The significance of the genetic source of variation (clones) and the different interactions detected by the ANOVA suggested individual regression analyses for each clone (Table 2).…”

“…The standard procedure based on the visual assessment of PPD is laborious and prone to large experimental error. Alternative approaches such as sugar/starch ratio or fluorescence screening have been evaluated, but so far offer little promise (Mahmod & Beeching, 2018).…”

“…A major factor affecting research on PPD is the large influence of environmental conditions (particularly near harvest time), age of the plant, handling of the roots during harvest and thereafter, and storage conditions (Zainuddin et al ., 2018). Experimental errors, therefore, are typically large and mask true genetic differences that may exist (Mahmod & Beeching, 2018). The accumulation of fluorescent compounds (mainly scopoletin) has been associated often with PPD (Saravanan et al ., 2016; Mahmod & Beeching, 2018; Zainuddin et al ., 2018).…”

Consumers, traders and processors consider post-harvest physiological deterioration (PPD) an important constraint. In Experiment 1, PPD was assessed three consecutive years in roots from five genotypes through seven storage days. PPD, scopoletin and dry matter content (DMC) was recorded during storage. Year, genotype, duration of storage and their interactions were significant. PPD was associated with duration of storage period, DMC and scopoletin contents. Ambient moisture and temperature during storage influenced PPD. In Experiment 2, roots from seven clones were harvested 10 months after planting from 30 consecutive biweekly plantings. PPD was assessed 0, 2 and 7 days after harvest. In 13 harvests, roots from plants pruned six days earlier were also evaluated. Results indicated large seasonal variation across genotypes. Pruning reduced PPD and DMC. Complex and contrasting relationships among the variables analysed were found. There is no uniform model explaining the relationship between PPD and the independent variables considered.
