Qualitative traits and shelf life of fig fruit (cv Melanzana) treated with Aloe vera gel coating
The fig (Ficus carica L.) cv Melanzana is typical of Southern Italy. This cultivar produces breba fruit in June and fig fruit in August. Some previous studies on the use of coatings extracted from stems of Aloe vera showed positive effects to maintain fruit quality during shelf life. However, there are no studies on breba fig fruit treated with Aloe vera coating. In this study breba fig fruit, cv Melanzana, was treated with an application of Aloe vera gel, sealed in macro-perforated bag and stored at 5°C for 10 days. The effect of application of the Aloe vera gel on the shelf-life of this fruit, and its quality attributes after application were evaluated measuring fresh weight, total solubl…
The effect of two growth bio regulators on the physiological, phenological and qualitative parameters of peach tree production
The risk that plants have not accumulated sufficient chilling units (CU) and the economic interest in anticipating flowering have led to growing scientific interest in the use of bio plant regulators to stop dormant peach trees in farms that use agronomic particulates in precision farming protocols. The trials were conducted in 2016 and 2017, on peach trees of the cultivar Maycrest, grown in a commercial orchard located in Metaponto, Basilicata (Southern Italy). A complete randomization experimental scheme was adopted; three theses (control, Fast and Regular® and Asy 23) and two different intervention periods have been provided for, the doses used have been 500g/hl for Fast & Regular® a…
Non-destructive determination of ‘Big Bang’ nectarine quality and harvest maturity
In nectarines, potential shelf life and quality at consumption are closely related to the ripeness stage of fruit at harvest. Usually, the harvest is based on color, firmness, sugar and acids content of fruit, although these determinations are carried out through destructive methods and in a limited number of samples. The technique of Vis/Nir spectroscopy is used for the development of a non-destructive index based on the difference of absorbance (IDA) between two wavelengths near the absorption peak of chlorophyll-a, and it allows monitoring of changes in ripeness processes directly in the field. The objective of this paper is to track changes in quality that occur during nectarine ripenes…
