Chitosan-based foliar application modulated the yield and biochemical attributes of peach (Prunus persica L.) cv. Early Grand

Abstract

Background Peach fruits are highly perishable leading to many pre- and post-harvest problems, which adds to the reduction in the potential yield and productivity. Chitosan is a natural polysaccharide, produced after alkaline chitin deacetylation. It is one of the most preferred biopolymers due to its biocompatibility, antioxidant, anticancer, biodegradability, antimicrobial, and non-toxic properties as well as being an economical material. A pre-harvesting experiment was carried out based on the problems of peach and the importance of chitosan. Results Peach trees were foliar sprayed with different concentrations of chitosan (0, 0.50, 0.75, and 1.0%) at different times (30, 50, and 70 days after full bloom) to elucidate the effect of chitosan to peach yield and fruit quality. The results showed that foliar application of chitosan (1%) caused significant increases in fruit weight, volume, tree yield−1, fruit firmness, titratable acidity, and ascorbic acid content but caused significant decreases in total soluble solid fruit juice pH and disease incidence of peach fruit. Similarly, foliar application of chitosan after 50 days of full bloom increased fruit weight, volume, yield tree−1, firmness, titratable acidity, and ascorbic acid content with the number of fruit kg−1, total soluble solids, juice pH, and disease incidence as compared to other application times. Conclusions It is concluded that chitosan at 1% applied after 50 days of full bloom improved most of the peach attributes studied compared to the other concentrations of chitosan at 0.50 and 0.75, and control for the production of quality peach fruit.

The promotion of plant growth and fruit features after the application of chitosan isolated from Parapenaeus longirostris shells

“…While, the decrease in the level of citric acid and amino acids after chitosan application might be due to the redirection of carbon skeletons resulting from glycolysis towards other metabolic pathways, especially those of vitamin C and inositol biosynthesis as well as anaerobic metabolism. This is in agreement with the results obtained by Sajid et al [9].…”

Biostimulants to Improved Tree Physiology and Fruit Quality: A Review with Special Focus on Sweet Cherry

“…For nectarines and peach, chitosan has also proven to be an interesting strategy to enhance the quality of fruits: nectarines treated with chitosan presented firmer pulp and higher soluble solids content [118], while, for peach, in addition to increased fruit dimensions and weight, higher yield, fruit firmness, acidity, and ascorbic acid were also found [119]. Yield, fruit dimension, and plant growth of mango were also improved by the application of chitosan [120].…”

Effects of different concentrations of Chitosan and application methods on growth and yield characteristics of chilli pepper (<i>Capsicum annum</i>)

“…In order to increase leaf greenness and sugar status, seedlings may need to be provided with critical nutrients (Wingler et al, 2006;Engels et al, 2012). Ncarboxymethyl Chitosan applied to maize increased the amount of N and N protein as well as the activity of vital N metabolic enzymes (Sajid et al, 2020;Boamah et al, 2023). The nutrient nitrogen is well-known for being necessary for the synthesis of numerous enzymes, cytokinin, and chlorophyll.…”
