Gibberellic acid coating: A novel approach to expand the shelf-life in green chilli (Capsicum annuum L.)

Changes in antioxidant and biochemical activities in castor oil-coated Capsicum annuum L. during postharvest storage

“…The probable reason of such outcome might be attributed to lesser metabolic activities (Özden and Bayindirli 2002 ) and delay in consumption of citric acids (Yaman and Bayindirli 2001 ). Citric acid is the prime substrate for respiration, wherein a decrease in acidity level and a rise in pH level are coupled with highly respiring fruits (Panigrahi et al 2017 ). However, the decline in titratable acidity is a vital event during ripening, since it turns the fruits less acidic or sour (Valero and Serrano 2010 ).…”

“…Capsicum annuum L. (green chilli), an important member of Solanaceae family, is mainly grown as a cash crop owing to its distinctly pungent non-climacteric fruits, enriched with vitamins and minerals. Inspite of having such high nutritional values it has limited storage-life (Panigrahi et al 2017 ), which is a major problem for fruits and vegetable growers. Following its harvest, the fruits undergo gradual deterioration due to desiccation, oxidative reactions, microbial growth, and other biochemical changes.…”

“…Herein, external coating(s), acting as partial barrier to water vapour, gases and restricting rapid metabolism, might be helpful to preserve the texture, quality and external appearance of harversted fruits, and in due course may also improve their storage-life, significantly influencing the functions of storage-associated biochemicals and antioxidants (Baldwin 1994 ; Li et al 2017 ; Panigrahi et al 2017 ). External coatings comprise hydrophobics (lipids or waxes), hydrocolloids (polysaccharides or proteins) or a combination of both the compounds (composite coatings).…”

“…Owing to such property, the castor oil coating on seeds of edible pulse or oilseed crops is being used traditionally, to extend the storage life since long, in the southern districts of Gujarat State, India (Parmar and Jain 2016 ). There are several reports on postharvest storage-life of C. annuum published till date that include semperfresh edible coating (Özden and Bayindirli 2002 ), shellac-based surface coating (Chitravathi et al 2014 ), essential oil (cinnamon) coating (Ali et al 2014 ), and gibberellic acid coating (Panigrahi et al 2017 ).…”

Morphological and molecular datasets for Kaempferia species

“…Twenty-four qualitative and quantitative characteristics were categorized and transformed into scores to represent each category available (Appendix 3). Leaf characters were classified according to Hickey [10] and colour was identified using the Royal Horticultural Society (RHS) colour chart [11], [12] (Appendix 4). The accessions were clustered by the unweighted pair group method using arithmetic average (UPGMA) method which it was indicated as a good cophenetic correlation of the original distance matrices.…”
