Studies on postharvest physiology of some important pear cultivars recommended for commercial production. III. Santa Maria.

Regional harvest maturity standards, storage properties and ripening characteristics of pear cv. Santa Maria fruits were investigated during 1985-86 and 1986-87. Fruit growth, flesh firmness, soluble solids, colour change, chlorophylls, pH, titratable acidity, starch content and quality were evaluated at weekly harvests during the 3-week harvest period. Compared with the first pick, increase in diameter and in length during successive harvests reached 17.8 and 13.3%, respectively, in the first season and 47.0 and 31.7%, respectively, in the second season, with an increase in volume of almost 400%. Optimum harvest time coincided with fruit firmness of 5.0-5.4 kg and the skin having a typical green ground colour. Fruits harvested at this optimum time could be stored successfully for 5 months at 0 deg C.
