MORPHOLOGICAL DESCRIPTION OF THREE POTENTIAL CITRUS ROOTSTOCKS MUHAMMAD JAFAR JASKANI*, HAIDER ABBAS*, M.M. KHAN, UMBREEN SHAHZAD AND ZAHOOR HUSSAIN
Abstract: Morphological studies showed that tree shape in Bitter sweet orange
and Yuma citrange was spheroid with spreading growth habit and wide
branch angle. Leaves were simple with dark green color, medium size
and brevipetiolate in Sour orange while Yuma citrange had trifoliate
leaves with medium and green color. Bitter sweet orange had the highest
leaf lamina length (10.4 mm) than other rootstocks. These rootstock
leaves had lanceolate shape with sinuate margins. Bitter sweet orange
yielded the maximum fruit weight (195.9 g) while Yuma citrange and Sour
orange had small and medium sized fruits, respectively. Fruit skin was
rough and yellow in all rootstocks but bitter sweet orange and Sour
orange showed white albedo with medium-strong adherence. Bitter sweet
orange and Sour orange fruit had strong attachment to stalk. Number
of segments/fruit was low in Bitter sweet orange as compared to the
other rootstocks. Seeds represented clavate shape in Bitter sweet orange
and Sour orange. The highest number of seeds was found in Bitter sweet
orange (27.9) followed by Sour orange (14.8). Seed of Bitter sweet orange
and Sour orange was polyembryonic while monoembryonic in Yuma citrange.
