Loquat fruit is especially susceptible to bruising since harvest is done after fruit matures in the tree. Fruit firmness decreases with ripening, handling during harvest, packaging and storage being critical in the final fruit quality. The higher the fruit firmness at harvest the lower the risk of fruit quality loss due to bruising. Calcium treatments have been shown to improve fruit firmness in apple, apricot, pear and peach, all of them belonging to the Rosaceae family like loquat. We tested in the field pre-harvest applications of foliar spray of different calcium chlorine and calcium chelate solutions in order to determine its effect on fruit firmness in a standard material test. We compared the effect of treatments in unprotected and in mesh-protected orchards. In both cases, calcium treatments increased fruit firmness up to 20 percent. The levels of firmness increase are comparable to those reported for other fruits of the Rosaceae family.
