Abstract

An experiment was conducted with an aim to study biochemical changes of fifteen varieties of guava stored at ambient storage conditions at Department of Horticulture, Chaudhary Charan Singh Haryana Agriculture University, Hisar, Haryana during rainy and winter season of 2018-2019. All varieties exhibited considerable variation in their performance for most of the biochemical parameters. It was observed that there was significant increase in TSS, during both the seasons, regardless of varieties. On the other hand, acidity, pectin content and ascorbic acid of all the varieties was found to be decreased over the passage of storage time. However, all the varieties exhibit increasing trends in reducing sugar, non-reducing sugar and total sugar but during winter season sugar parameters was found to be first increased for six days then slightly decrease on 8th day. Among varieties, Hisar Safeda exhibited maximum reducing sugar and in winter season. Total sugar and reducing sugar in winter season and TSS in rainy season were recorded maximum in cv. Pant Parbhat. Pectin content during both the seasons and ascorbic acid, total sugar and non-reducing sugar in rainy season were recorded maximum in cv. L-49. Barf Khana had the maximum ascorbic acid in winter season and acidity found minimum in Arka Mridula and Allahabad Safeda in rainy and winter season respectively. Winter season fruits of all the varieties were much more superior to rainy season fruits.

Conclusion

The obtained results showed decline in ascorbic acid, acidity and pectin content, with the passage of storage period, during both the seasons, irrespective of cultivars. On the other hand, TSS was found to be following an increasing trend. Among varieties, Hisar Safeda exhibited maximum reducing sugar. Firmness, total sugar, specific gravity and reducing sugar in winter season and TSS in rainy season were recorded maximum in cv. Pant Parbhat. Pectin content during both the seasons and ascorbic acid, total sugar and non-reducing sugar in rainy season were recorded maximum in cv. L-49. Barf Khana had the maximum ascorbic acid in winter season and acidity found minimum in ArkaMridula and Allahabad Safeda in rainy and winter season respectively. Winter season fruits of all the varieties were much more superior to rainy season fruits.
