“…Nielsen et al [25] found that the SSC value of apple fruit was not affected by different spray programs (early, mid, and late season) of calcium chloride. Decreased SSC in treated fruits is probably due to the fact that calcium decreases respiration and metabolic activity, thus delay the process of fruits ripening [32,33].…”

Calcium (Ca) plays major roles on the storage life and quality apples. In this study, the influence of calcium chloride (CaCl2) and two organic calcium compounds including Calcicat and Folical at four different times of application on the quality and shelf life of ‘Granny Smith’ apples during two growing seasons. Quantitative and qualitative attributes were evaluated at harvest and after three- and six-months cold storage. In the first year, Folical all-season and mid-season sprays resulted in a significant increase in Ca concentration. In the second year, early-season spray resulted in significant Ca increase compared to control. In the first year, the early-season spray program of Folical had the highest yield and fruit weight. The use of calcium compounds in all timing programs reduced fruits soluble solids concentration (SSC) at harvest compared to control treatments. In both years, at harvest, no significant difference was observed among treatments regarding the ‘Granny smith’ apple firmness. In the first year, the chlorophyll content of ‘Granny Smith’ apple peels were affected by spray timing and the type of calcium compound. In both years, Fruits treated with Ca had lower ethylene concentration and brightness index (L*) than controls. In the second year, Folical spray decreased the percentage of superficial scald incidence for three months storage. During the first year, all-season Calcicat spray and in the second year early-season Folical spray showed the lowest percentage of scald disorder after six months storage. In the first year, the all-season spray program and in the second year Folical spray decreased the severity of scald after three months of storage.

“…Calcium stimulates the development of lignin and cellulose and the translocation and formation of carbohydrates ( Aguayo, Escalona & Artés, 2008 ; Wang et al, 2022 ; Yang et al, 2023 ), so it is a significant factor in inflorescence and flower formation ( White & Broadly, 2003 ). Calcium also increases the mechanical power of the cell wall because the main component of the cell wall in plants is calcium pectate, which plays a significant role in the establishment of the pedicel attachment to proximal fruit, thus reducing fruit drop ( Guardiola & Garcia, 2000 ; El-Shafey, Abd El-Rahman & El-Azaze, 2002 ; Liu et al, 2019 ; Zaman et al, 2020 ).…”

Many citrus species and cultivars are grown successfully in tropical and subtropical countries, as well as in arid and semi-arid regions with low levels of organic matter and low cation exchange, resulting in lower nutrient uptake by the plant. The essential nutrients needed for citrus flowering and fruit set are limited in winter due to a reduction in transpiration rate, negatively effecting vegetative growth, flowering, yield, and fruit quality. The present investigation was carried out to assess the nutritional status, fruit yield parameters, and fruit quality of Valencia orange trees after foliar spraying of seaweed extract (SW) combined with calcium chloride and boric acid and their combinations in the 2020/2021 and 2021/2022 seasons. The treatments were arranged in a split-plot design (three levels spraying seaweed extract × four levels spraying calcium chloride and boric acid and their combinations × four replicates × one tree/replicate). The results indicated that all of the characteristics measured, including leaf chlorophyll, leaf mineral contents, fruit yield parameters, fruit physical properties, and fruit chemical properties, were significantly affected by the foliar spraying of seaweed extract (SW) combined with calcium chloride and boric acid and their combinations. Although all treatments increased the productivity and the physical and chemical properties of Valencia orange fruits compared to the control, a treatment of 10 g/L SW combined with 0.5 g/L boric acid and 1 g/L calcium chloride produced superior results. This ratio of SW, boric acid, and calcium chloride is therefore recommended to enhance productivity and improve the physico-chemical properties of Valencia orange for greater fruit yield.

“…Cherry cultivation in Pakistan, mainly in temperate zones like Quetta, Kalat, Ziarat, and others, lacks comprehensive information. Pakistan produces over 2,000 tons of Cherries annually but doesn't export those (El-Shazly et al, 2013). Cherry cultivation covers about 897 hectares in Balochistan, producing approximately 1,507 tons annually.…”

ABSTRACT Cherry is an important fruit being grown throughout world and Pakistan. This research focused on investigating the occurrence of Cherry fruit rot in various locations within the Quetta district of Balochistan. Infected Cherry fruit samples were collected from Joint Road, Double Road New Adda, Azar Ghangi, and Kansi Road. The specimens underwent isolation and morphological identification procedures were carried out at the mycological laboratory of the Department of Plant Pathology, Balochistan Agriculture College, to determine the causal agent (Aspergillus niger). Additionally, the study explored the impact of diverse essential oils on the linear colony growth of Aspergillus niger under controlled in-vitro conditions. Essential oils, such as Rose oil, Neem oil, Coconut oil, and Cinnamon oil, displayed varying inhibitory effects on Aspergillus niger growth. These findings enhance our understanding of interactions between agents and the fungus, paving the way for further fungal growth control research. The study contributes practical insights for managing Aspergillus niger growth, potentially advancing strategies in the field of fungal growth control and management.
