“…The calcium salts are known to be involved in a number of physiological processes concerning membrane structure, function and enzymatic activity. The exact role of calcium, like that of all minerals, is still obscure, but it is important for cell wall development (Katiyar et al 2008;Holb et al, 2012). Zinc (Zn) is an essential micro element for plants, being involved in many enzymatic reactions and is necessary for their good growth and development (Razzaq et al (2013).…”

An investigation was conducted on uniform, healthy, eight year old trees of Nagpur mandarin (citrus reticulata Blanco) at Fruit Research Farm, Department of Fruit Science at College of Horticulture and Forestry, Jhalawar during 16 September, 2014 to 1 March, 2015. Various doses of calcium nitrate (1.0%, 2.0% and 3.0 %), boric acid (0.2 %, 0.4 % and 0.6 %) and zinc sulphate (0.2 %, 0.4 % and 0.6 %) were sprayed before harvesting and compared with untreated ones. The results obtained indicated that the trees sprayed with T27 i.e. (calcium nitrate 3.0 % + boric acid 0.6 % + zinc sulphate 0.6 %) showed maximum increase diameter of fruit, fruit weight, fruit volume, number of fruits per plant, fruit yield per plant, estimated yield per hectare, reducing sugar, non reducing sugar, total sugar, juice per cent, sensory score and reduced peel thickness over control. Further, T24 treatment combination (calcium nitrate 3.0 % + boric acid 0.4 % + zinc sulphate 0.6 %) has also significantly increased number of segments per fruit, TSS, TSS: Acid ratio, ascorbic acid content, and reduced number of seeds per fruit and acidity percent of fruits.

“…Calcium applications can reduce the respiratory intensity and ethylene release rate of post-harvest apples, and can delay senescence (6). Moreover, post-harvest treatment of apples with calcium chloride (CaCl 2 ) may delay softening and reduce the incidence of physiological disorders, such as bitter pit and flesh browning (6,7) and both pre-harvest spraying with CaCl 2 and post-harvest infiltration of CaCl 2 solution can reduce the symptoms of brown rot (8). Salicylic acid (SA) is a simple phenolic hormone commonly present in plants that has a unique function for regulation of the processes of growth, development, and aging (9).…”

The effects of calcium chloride (CaCl 2 ) and salicylic acid (SA) alone and in combination against postharvest anthracnose rot on apples caused by Colletotrichum gloeosporioides were investigated, and influences on several quality and disease resistance related parameters were evaluated. Dipping in a solution of 5% CaCl 2 +5 mM SA for 10 min was the most effective approach to inhibit C. gloeosporioides both in vitro and in vivo. A combined CaCl 2 and SA treatment had the best efficacy for mitigation of the decline of total soluble solid content, titratable acidity, and firmness. Quality preservation plays an important role in apple post-harvest freshness. CaCl 2 in combination with SA demonstrated the strongest effect for induction of disease resistance and maintenance of postharvest freshness of apples.

“…Calcium alters intracellular and extracellular processes, resulting in retarded ripening as exemplified by lower rates of color change, softening, and CO 2 and ethylene production, increase in sugar, and reduction in total acid content (Conway, 1987;Manganaris et al, 2005;Raese and Drake, 1993). The pre-and postharvest application of calcium salts has been used successfully in many fresh fruits to reduce loss of firmness and slow down the ripening process (Floros et al, 1992;Holb et al, 2012;Mohammed et al, 1991;Saftner et al, 1998;Souty et al, 1995). CaCl 2 has been primarily used for preharvest treatment.…”

We reported previously that the preharvest treatment of broccoli microgreens with 10 mmol·L−1 calcium chloride (CaCl2) increased the yield and postharvest quality. The objective of this study was to investigate whether other calcium forms have the similar effect, in particular, after postharvest dip in calcium solution. Our results are as follows: 1) Preharvest spray without postharvest dip: Both 20 mmol·L−1 calcium lactate (Ca lactate) and calcium amino acid (Ca AA) chelate significantly improved broccoli microgreens quality and inhibited microbial populations as compared with the water-only control during storage at 5 °C for 21 days. However, they were less effective than 10 mmol·L−1 CaCl2. 2) Postharvest dip without preharvest spray: The microgreens sprayed with water-only control were dipped in 0, 25, 50, or 100 mmol·L−1 Ca lactate solution containing 100 μL·L−1 chlorine immediately after harvest. During storage at 5 °C for 14 days, 50 mmol·L−1 Ca lactate dip showed the highest overall quality and lowest tissue electrolyte leakage. 3) Preharvest spray and postharvest dip: Combined preharvest 10 mmol·L−1 CaCl2 spray and postharvest 50 mmol·L−1 Ca lactate dip resulted in better postharvest quality than individual pre- or postharvest calcium treatments. However, the preharvest 10 mmol·L−1 CaCl2 spray without postharvest dip displayed a best overall visual quality and longest storage life. Our data indicate that pre- and postharvest calcium treatments have positive effect on maintaining the microgreens quality and extending shelf life. However, current postharvest dip/spinning/drying method profoundly reduces the shelf life due to mechanical damages. Technologies to optimize microgreens wash are needed to provide ready-to-eat product. Alternatively, the wash step can be avoided when the microgreens are grown under controlled settings.
