dc.description.abstractThe present studies were conducted at Fruit Research Farm, Department of Fruit Science, Punjab Agricultural University, Ludhiana during the year 2021-22 on four lime and lemon varieties viz. Baramasi Lemon, Tahiti Lime, Galgal and Sweet Lime. The fruit and leaf samples of Lime and Lemon cultivars were collected from 30 days after fruit set till commercial harvesting at 30 days intervals starting from the month of April. The physicochemical parameters like fruit size, weight, juice content, seed size, moisture content, TSS, TSS/acid ratio, carotenoids and sugars were recorded maximum at final stage of harvesting. Titratable acidity, vitamin C and peel thickness exhibited a declining trend from first to final stage of fruit harvesting. In all four varieties of lime and lemon peel contained greater antioxidant activity, total phenolic content, hydroxyl ion free radical scavenging activity and total flavonoid content as compared to pulp of fruits. In peel and pulp, antioxidant activity declined during fruit development. Limonin was recorded highest in seeds followed by peel and pulp irrespective of stages of development. Sweet Lime was found the most suitable cultivar for table as well as medicinal purposes due to higher level of TSS, sugars, antioxidants, flavonoids and vitamin C content. However, fruits of Baramasi lemon, Galgal and Tahiti Lime are also good sources of different types of antioxidants at initial stages of development. In terms of mineral nutrition leaves contained higher concentrations of nutrients followed by peel and pulp exhibiting a distinct pattern during fruit growth and development.
