Development of physiological and biochemical indices of maturity of dessert plums.

Patterns of fruit growth and ripening were investigated in 4 plum cultivars (Gulfruby, Beauty, Shiro and Rubyred) grown in New South Wales. Fruit size was measured at weekly intervals from pit hardening until tree-ripeness. Samples of fruit were harvested at weekly intervals from pit hardening and stored at 20 deg C at high RH. Changes in skin colour, firmness, soluble solids and titratable acidity were recorded. Respiration and ethylene production rates were measured for 6 days after harvest. Ripening in Gulfruby was associated with a climacteric pattern of respiration and ethylene production. Changes in skin colour in Beauty, Shiro and Rubyred were not associated with an increase in ethylene production. An increase in ripe plum aroma was associated with increased ethylene production in Beauty and Shiro. Fruits of all cultivars softened gradually during growth and ripening. One- and 2-dimensional gel electrophoresis were used to detect changes in protein profiles during maturation and ripening.

 Differences in protein profiles were found in cultivars Gulfruby and Shiro plums between the pre- and post-climacteric stages.
