FRUIT GROWTH AND DEVELOPMENT IN THREE CULTIVARS OF CITRUS: ORANGE, KINNOW AND FEUTRALL’S EARLY

Abstract

Sweet Orange (Citrus sinensis) and two varieties of Mandarin; Kinnow and Feutrall’s early were studied for their fruit growth. For this purpose an experiment was conducted at National Agriculture Research centre (NARC), Islamabad during the year 2008. Gravity method was used to determine the cell division and cell enlargement. Feutrall`s early, Kinnow and Sweet orange cultivar “Salustiana” exhibited a sigmoidal growth pattern. A significant variation in fruit size was observed among the three fruits. Feutrall`s early had the smallest fruit size (48.23mm), Kinnow and Sweet orange cultivar “Salustiana” had fruit size of 59.43 and 68.45 mm, respectively.
