Abstract
The Mediterranean basin area is characterised by photosynthetic photon flux density, which is often well above the saturation level point of the leaf. This phenomenon has been exacerbated by global warming, giving rise to reactive oxygen species in chloroplasts, which can damage tissues (photodamage) and reduce photosynthetic potential.
Citrus bergamia Risso et Poiteau (bergamot) was successfully cultivated in Southern Italy for the high-quality essential oil extracted from the flavedo fruit and freshly consumed for its numerous health properties.
This study aimed to use two reflective materials, caolin and calcium carbonate, to improve tree productivity. The experiment was conducted over two years in southern Italy. A randomised block design was used in this study. At harvest, fruit samples were randomly detached.
The results showed that bergamot trees treated with reflective materials significantly increased the average yield per plant compared to that of the control plants, but the effect was stronger with caolin and calcium carbonate. The number of fruits at harvest was similar between the treatment and control trees; therefore, there was no effect of the two reflective materials on decreased fruit pre-harvest, but the change in yield was attributable to an increase in fruit size. This can be attributed to the higher performance of the leaves covered by reflective materials. Regarding maturation, the indices were not influenced by the treatment, whereas ascorbic acid was higher in the fruit of the treated trees. Essential oil production was improved by this treatment. This improves both the essential oil yield, used as a base for the worldwide perfume industry, and the nutraceutical parameters for fresh consumption, justifying the increased costs of applying reflective material on the tree.
期刊介绍：
Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
