Experiment Background
Mango is one of the main fruits of our country and it is known as King of fruits. The cultivar Kesar is most delicious, juicy, pulpy, tasty and most favourite fruits of south Gujarat region. But their perishablity and lack of preservation in common refrigerator compel us to finish within 2-3 days after full ripening. Calcium has two major role in plant system first it support firmness of cell wall as calcium pectate and secondly it acts as secondary messenger in signal transduction pathway. The other roles are also accountable such as regulation of stomatal behaviour, calcium calmodulin complex etc. Calcium ions passively can diffuse within the cell wall structure because plant cell wall porosity is approximately 3.5 to 9.2 nm, while calcium ions are about 0.1 nm. In fruit preservation practices, when fruit parenchyma cells are dipped in a calcium salt solution, calcium ions are transported primarily through the apoplast, or intercellular spaces, where they are attracted by negatively charged carboxyl groups in the homogalacturonan that constitutes pectin in the middle lamella and cell wall. The negatively charged chloride or lactate ions remain unbound in solution. CaCl2 treatments have been given on many fruits by different laboratory and they were shown positive results in extending the shelf life by keeping the quality trait. Hence, in this research, efforts will be done for extending the shelf life of mango with intact or elevated quality and aroma in our popular cultivar Kesar.
