Abstract : Floral malformation was examined in 7- to 10-year-old trees of the mango cultivars Dashehari, Amrapali, Mallika and Kensington growing at Lucknow, India. Physiological characteristics were measured in leaves of healthy and malformed twigs. The rate of flower malformation was highest in the American cultivar Kensington (19.2%), followed by Mallika (12.3%), and was lowest in Dashehari (4.6%). Leaves on twigs with malformed flowers generally had a lower rate of photosynthesis than leaves on twigs with healthy flowers (3.98 and 5.23 µmol?m-2?s-1, respectively), lower concentrations of sugars, starch and chlorophyll, and a higher rate of respiration (2.86 and 2.08 µmol?m-2?s-1, respectively).
