‘Patharnakh’ (PN) (Pyrus pyrifolia Burm. Nakai) and ‘Punjab Beauty’ (PB) [Pyrus communis L. × Pyrus pyrifolia Burm. (Nakai)] are leading low-chill pear cultivars of subtropics of India. Diurnal temperature and relative humidity during fruit harvest period is high which considerably affect the shelf life of fruits. Fruits of ‘PN’ and ‘PB’ pear harvested at physiological maturity were stored for 12 days at ambient temperature and effects of storage temperature on physical and qualitative parameters were studied. Both cultivars showed reduction in fruit weight and firmness, reducing sugars, sucrose, starch and pectin content. However, total soluble solids and juice acid content increased during storage. Sucrose synthase activity and sucrose content showed significant positive correlation in ‘PN’ cultivar. Activities of fruit softening enzymes such as polygalacturonase (PG) and cellulase was enhanced; whereas, pectinmethylesterase (PME) was reduced during storage. Fruit firmness was negatively correlated with PG in both the cultivars. In ‘PN’ cultivar, fruit firmness was positively correlated with cellulase and negatively with PME enzyme but reverse trend was observed in ‘PB’ cultivar. Fruit minerals content didn’t show any substantial disparities in both the cultivars during storage. ‘Patharnakh’ and ‘Punjab Beauty’ fruits maintain desirable quality parameters up to 6-9 days and 3-6 days, respectively, during storage at ambient conditions.

“…37 Se could increase the AI activity but had no obvious effect on the activities of NI and SS in berries, and AI activity showed a significant positive correlation with glucose and fructose. 27 However, Ren et al 39 reported that AI activity was not significantly correlated with sucrose content during fruit development. It can be seen that the roles of enzymes related to sugar metabolism were different in different crops.…”

Effects of exogenous sucrose and selenium on plant growth, quality, and sugar metabolism of pea sprouts

et al. 2021

BACKGROUND Pea sprouts are considered a healthy food. Sucrose is a key nutritional factor affecting taste and flavor. Meanwhile, selenium (Se) is an essential micronutrient that plays multiple roles in wide variety of physiological processes and improves crop quality and nutritional value. Nonetheless, the effects of the combination of sucrose and Se treatment on growth, quality, and sugar metabolism of pea sprouts have not been explored. RESULTS The results revealed that sucrose at 10 mg L−1 obviously increased fresh weight, vitamin C, soluble protein, soluble sugar, fructose, glucose, and sucrose contents. Se treatments also improved nutritional quality, but higher Se (2.5 mg L−1) significantly inhibited the growth of seedlings. Interestingly, the combined application of sucrose (10 mg L−1) and Se (1.25 mg L−1) could effectively promote vitamin C, sucrose, and fructose contents, especially the Se content, compared with Se application alone. Additionally, there were significant differences in the regulation of sugar metabolism between Se alone and combined application of sucrose and Se. Acid invertase and neutral invertase play a pivotal role in the accumulation of soluble sugar under Se treatments alone, and acid invertase might be the key enzyme to limit sugar accumulation under combined application of sucrose and Se. CONCLUSION The moderate combined application of sucrose (10 mg L−1) and Se (1.25 mg L−1) more effectively regulated sugar metabolism and improved nutritional quality than Se application alone did. © 2021 The Authors.

“…This is probably due to the differences in the soil maintenance system. Ren et al (2021) studied the effects of sodium selenite spray on Fuji dwarf apple production and quality. The authors had a high value at concentration 150 mg/L for fruit weight (309.8 g), at 200 mg/L for fruit diameter (89.17 mm), at 100 mg/L for fruit shape index (0.93) and fruit firmness (11.71 kg.cm −2 ), at 50 mg/L for soluble solids (16.50%), and at 0 mg/L for titratable acid (0.28%).…”

Apple (Malus domestica) is cultivated worldwide and is the most widely grown species in the genus Malus (Li et al., 2018). There are more than 7,500 known cultivars of apples, resulting in a range of desired characteristics; among the different varieties of apples, only 20 varieties are commercial of which only five types (Red Delicious, Golden Delicious, McIntosh, Rome Beauty, and Granny Smith) are evaluated to have major worldwide production. Annual Worldwide apple production is around 83.1 million tons, with China accounting for half of the total production (Ferree & Warrington, 2003;Kunihisa et al., 2016;Matsumoto, 2014). Apples are the fourth largest fruit crop in the world after orange, grape, and banana varieties (Forsline et al., 2003).The term quality defines the superiority of the product or its suitability for specific use, quality is a human structure that has many features or properties. However, apple quality depends on its physical and visual characteristics and chemical composition . The development of these attributes is probably initiated when the fruit is very young, and the final product depends on many factors, such as cultural practices, environmental conditions during fruit development, maturity at harvest, and storage treatments (Vanolia & Bucchiri, 2012;Xie et al., 2021).Fruit quality has been evolving throughout time, at present, fruit production and commercialization extend to delivery criteria to which the consumer imposes. Setting the proper harvest date is not only useful in obtaining a better product but also increases productivity, however, the common attributes associated with quality are fruit size, fruit weight, fruit firmness, fruit total soluble solids content, fruit acid content, fruit pectin, and fruit polyphenol content (Mupambi et al., 2018). Apple quality rapidly changes during storage and, therefore, substantially influences the acceptableness of the consumers. At the first step, it is judged by manifestation containing color and size and secondly by the content of total soluble solids (TSS), texture, and/or titratable acidity, these parameters would supply substantial information to the consumers in identifying the most nutritional fruit. The influence of diverse treatments on apple quality has extensively been considered during storage by
