Modern Post Harvest Pathological Aspect of Spongy Tissue in Different Varieties of Mango

Abstract

Indian mangoes, around 60% of the global mango trade, are well-known for their delicious flavor and aroma. Nevertheless, this fruit is prone to quotspongy tissue,quot an internal physiological disorder. Quality control is challenged because the diseased fruits do not exhibit any external symptoms and the defect is only discovered through cutting or non-destructive X-ray scanning. Several post-harvest pathological aspect of spongy tissue were studied in different varieties of mango like Badam, Dasheri, Kesar, Parbhani Hapus, Langra, Lalbagh, Alphonso, etc. along with some local mangoes collected from the Parbhani fruits market. The method used to detect the presence of spongy tissue in mango fruits was non-destructive X-ray scanning technology. In the present work, spongy tissue disease symptoms and incidence were studied. An attempt was also made to investigate the exact cause of the spongy tissue in the mango fruits. newlineInitially, the occurrence of spongy tissue was studied in several fruit samples of different mango varieties and we found that there are some varieties such as Badam, Parbhani Hapus, Kesar, Alphonso, and local variety-1 showed symptoms of spongy tissue when cut and internally evaluated. Thus it can be stated that these varieties are more susceptible to spongy tissue occurrence. However, spongy tissue was not found in the many varieties like Amrapali, Dasheri, Khutus, Lalbagh, Langra, Local variety-2, Malika, Neelum, Rajapuri, and Totapuri suggesting less susceptibility to spongy tissue disorder. newlineSpongy tissue symptoms were also studied in the affected mango fruits. The morphological study of spongy tissue affected fruits shows that healthy ripe and spongy ripe fruits are similar in their external appearance. Also, there is no difference in the peel color (yellow) of both healthy and affected fruits. The only variation seen is the pulp color and texture of healthy and affected fruits. The spongy pulp was rough, leathery, corky, and whitish or pale yellow whereas healthy pulp is soft, orange-yellow colored.
