Shading Net and Partial Covering Plastic Film Do Not Affect Phenology, Photosynthetic Activity or Fruit Quality Traits of Kensington Pride Mango

Abstract

Mango cultivation in a protected environment is becoming widespread in the Mediterranean basin where the species has to face unfavorable weather conditions which do not occur in its native cultivation areas. Besides open-air cultivation, greenhouses-and other protection systems such as shading nets and partial covering of plastic films-have been tested recently. In this study, we focused on assessing the effect of a shading net, and a partially covering plastic film, on the development of "Kensington Pride" mango fruit skin-color, its final quality, and the plants' photosynthetic activity. A new method of measuring mango skin-color on different sides of the fruit is proposed. No difference was observed with regard to the observed parameters between the plants cultivated under the two different protection systems and those growing in the open air. It can, therefore, be stated that such cultivation techniques do not alter the development of the mango fruit and its appearance, nor the plant's photosynthetic activity.
