Effects of Different Rootstocks on Storage Life and Quality of Loquat Fruit (cv. Gold Nugget)

Abstract

In this study, the effects of rootstocks on storage life and quality in Gold Nugget loquat grafted on quince, hawthorn and loquat rootstocks were investigated. After harvest, fruit were placed in plastic boxes (2 kg) covered with stretch film and stored for 45 days at 5 ± 0.5°C and 90 ± 5% RH. Weight loss, fruit firmness, total soluble solid, titratable acidity, maturity rate, respiration rate, ethylene production, CO2 and O2 concentrations in package, skin colour (L*,a*,b*,C*,h°), decay rate and sensory quality of fruit were determined at 15-day intervals during storage. The same analyzes were repeated for shelf life evaluation after keeping fruit 2 days in ambient condition (20°C and 70±5 RH%). Fruit grown on quince rootstock had the best results for maintaining external appearance, titratable acidity, maturation rate and vivid skin colour. The lowest decay rate and respiration rate during storage were also obtained from this combination. Quince and loquat seedling rootstocks had similar results for sensory quality and decay rate. Covering boxes by stretch film (20 µm) reduced the weight loss in the all the combination of scion/rootstock but, increased pathogens development. These findings revealed that fruit, obtained from the combinations of Gold Nugget variety with quince and loquat seedling rootstocks, can be stored with good quality for 30+2 days at 5°C and 90 ± 5 RH%.

Influence of Scion/Rootstock reciprocal effects on post-harvest and metabolomics regulation in stored peaches

“…After obtaining substantial yield, proper post-harvest storage of peach fruit is necessary to increase the storage life for extended/distant market availability. The findings of other researchers ( Tepe and Koyuncu, 2020 ) also support the contention regarding great influence of rootstocks on scion cultivar for storage and quality parameters. Reig et al (2020) also reported that appropriate rootstock selection is very important for establishment of an orchard.…”

Advances in loquat post‐harvest preservation and the application of nanotechnology for its active packaging

“…For the objective of preserving and maintaining the quality of the fruits, effective preservation methods must be established in order to increase the shelf life of loquat (Figure 3). fruit's quality and give buyers a superior quality product (Seyla & Koyuncu, 2020). Cold storage is a practical method for extending the shelf life of loquat fruit after harvest (Hou et al, 2021).…”

“…Temperature is one of the most significant factor which may affect the storage time. The cold storage method is utilized to preserve the fruit's quality and give buyers a superior quality product (Seyla & Koyuncu, 2020). Cold storage is a practical method for extending the shelf life of loquat fruit after harvest (Hou et al, 2021).…”

“…Cold storage is a practical method for extending the shelf life of loquat fruit after harvest (Hou et al, 2021). Low temperatures (5–7°C) were crucial in minimizing post‐harvest losses and increasing the storage time of loquats, according to Seyla and Koyuncu (2020). On one hand, the low storage temperature decreases the fruit's respiratory activity, causing a decline of ATP and enzyme activity, which lowers cellular respiration intensity and prevents the manufacture of C 2 H 4 .…”
