Experiment Title Effect of pre-harvest bagging on fruit quality of guava
Research Type Departmental Research
Experiment Background The bagging technique, which was first utilized in Japan in the 20th century for pears and grapes, is now widely applied in Asian countries (Japan, China, Korea), Australia and the USA, protecting fruits from the surrounding environment (mainly from light and pathogens, then stresses related to temperature, water/humidity, and air movement) with a sort of shield—a physical barrier around the fruit. In fact, bagging consists essentially of enclosing a young fruit in a food bag by capping the bag with a ribbon or a clamp on the fruit stalk. Isolating the fruit from the external environment protects it during development from mechanical or biotic damage, especially in regions where fruits are prone to attacks by fungi, bacteria, insects and even birds. The purpose is to obtain fruits without external imperfections, and with desired shape and color depending on the regional or national consumer preferences for the specific fruit. The expected color changes in comparison to non-bagged fruits can therefore correspond either to a reduction or an increase in color or even a greater homogeneity of the color itself. This review aims to show an analysis of the effects of bagging on the quality of the fruit, particularly on the effects on the external color, which is one of the main quality attributes of the fruit, taking for granted the protection provided by the bag against pathogens, pests or mechanical damages.
