“…Martinsson et al, (2006) also observed that application of calcium nitrate in Elsanta Strawberry contributed to more firmness of the fruits. These findings are in line with those reported by Gupta et al, 1980in grapes, Sudha et al, 2006 in sapota fruit, Goutam et al, (2010) in guava, Barwal et al, (2015) in apple, Raja et al, (2015) in peach, Mahajan and Sharma (2000) in pear, Gamal (2012) in apricot, Saran et al, (2004)…”

An experiment entitled "Effect pre harvest spray of different forms of calcium (CaCl 2 , Ca(NO 3 ) 2 , CaSO 4 each at 1 and 2%) on post-harvest quality of guava cv. Allahabad Safeda was conducted under randomized block design during the period of July, 2018 to January, 2019 at Fruit research station, Sangareddy, SKLTSHU, Telangana. The different levels of calcium had significant influence on the quality parameters. Various physical parameters like fruit length(cm), fruit diameter (cm), fruit weight (g), fruit firmness (kg/cm 2 ), shelf life (days), PLW(%), spoilage(%) and bio-chemical parameters like TSS (ͦ Brix), ascorbic acid (mg/100g), titrable acidity (%), total sugars (%), reducing sugars (%), non-reducing sugars (%) and Brix: Acid ratio were recorded. Among different forms of pre-harvest sprays of calcium, Ca(NO 3 ) 2 @ 2% has recorded significantly the highest total soluble solids (11.39 ͦ B ), ascorbic acid (159.49mg/100g), total sugars (9.00%), reducing sugars (5.23%), non-reducing sugars (3.78%), TSS: Acid ratio (31.08), fruit firmness (10.03kg/cm 2 ), shelf life (8.51days) when compared to control. The same treatment recorded minimum acidity (0.37%), PLW (11.63%) and spoilage percentage (62.86%). Ca(NO 3 ) 2 @ 2% emerged as best treatment to improve the quality attributes of guava cv. Allahabad Safeda.

“…Preharvest treatment with moringa leaf extract, boric acid, and chelated calcium recorded the lowest values of weight loss especially 5% MLE + 1% B + 2% Ca EDTA. These results agreed with (Tsomu and Patel 2014;Raja et al 2015, andKaur et al 2019) the report that weight loss in calcium and boric acid treated fruit was lower than untreated during storage. It may be due to the role of calcium and boron applications that have shown to be effective in terms of membrane functionality and integrity maintenance (Pilbeam and Kirkby 1983), with lower losses of phospholipids and proteins and reduced ion leakage (Lester and Grusak 1999), which could be responsible for the lower weight loss.…”

“…The results indicated that there was a reduction in fruit firmness with prolonging storage period in all treatments as well as control fruit (Table 2), but the highest firmness value was obtained in treatment 10% MLE + 1% B + 2% Ca EDTA in the two seasons. This increase in fruit firmness might be due to the high calcium content in moringa leaf extract (Mishra et al 2013), which goes in parallel with those previously mentioned by Thanaa et al (2017) who reported that foliar application of moringa leaf extract increased firmness of Hollywood plum, beside treatment with chelated calcium led to an increase of the concentration of calcium in treated fruit through active absorption and deposition of calcium in epicarp and mesocarp of fruits (Raja et al 2015). In this respect, Crisosto and Michailides (1991) and Plich and Wojcik (2002) found that foliar preharvest calcium sprays effective in held on retain fruit firmness at harvest and consequently a slower softening during long-term storage at low temperature.…”

Background Plum fruit has a short shelf life with a rapid deterioration in quality after harvest. The main aim of this study was to evaluate the effect of preharvest treatments by moringa leaf extract (MLE), boric acid (B), and chelated calcium (Ca EDTA) on Hollywood plum fruit quality attributes bioactive compounds and antioxidant activity during cold storage. Plum trees were sprayed twice: at full bloom stage and 1 month later with T1, 5% MLE + 1% B + 2% Ca EDTA; T2, 5% MLE + 2% B + 3% Ca EDTA; T3, 10% MLE + 1% B + 2% Ca EDTA; T4, 10% MLE + 2% B + 3% Ca EDTA; and T5, water only as control. At maturity stage, fruits were harvested and stored at 0 ± 1 °C and RH 85–90% for 8 weeks. Results At the end of storage, all studied treatments exhibited significantly higher sensory quality: firmness, color, soluble solid content:titratable acidity ratio, total anthocyanin content, total flavonoids content, total phenolic content, and antioxidant activity than control. Conclusions It could be concluded that preharvest treatment with moringa leaf extract, boric acid, and chelated calcium could be a safe and eco-friendly to improve and maintain plum quality attributes and especially their content of antioxidant compounds during cold storage periods.

“…From the day of harvesting to 35 days of storage, Ca(NO ) @ 2.0% fruits treated with two sprays of 3 2 recorded minimum decline (13.75%) in pulp-stone ratio as compared to control fruits (20.31%), followed by fruits received one spray of Ca(NO ) @ 1.0%. Similar view was 3 2 shared by Raja et al (2015) in peachfruits. Total soluble solids: During storage, TSS contents varied significantly with different calcium treatments.…”

: An experiment was conducted to study the influence of pre-harvest applications of different concentrations of calcium nitrate on various physico-chemical parameters of plum ( L.) Satluj Purple under cold storage conditions. Uniform and healthy plants Prunus salicina cv. of plum Satluj Purple were sprayed with calcium nitrate (1.0, 1.5 and 2.0 %) in 2 and 3 week of April and control plants were water sprayed cv. nd rd only. Fruits from both treated and control plants were harvested at colour break stage, and then stored at low temperature conditions (0–1 °C and 90–95 % RH) for 35 days. Evaluation of different physico-chemical parameters were made on 0 day and after 7, 14, 21, 28 and 35 days of storage. The results revealed that two sprays of Ca(NO ) @ 2.0 % retained maximum pulp: stone (15.37), total soluble solids (12.93 %), 3 2 titratable acidity (0.69 %), reducing (6.52 %) & non-reducing sugars (2.64 %) and total phenolics content (101.19 mg 100g ) at the end of -1storage. The fruits treated with two sprays of Ca(NO ) @ 2.0 % were effective in maintaining the quality of fruits without any spoilage up to 35 3 2 days under low temperature storage conditions.
