In recent years, the cultivation of tropical fruit crops has increased in Mediterranean basin, especially southern Italy. surveys conducted from 2014 to 2019 woody canker and shoot blight were observed on mango plants (cvs. Kent, Keitt, Sensation, Osteen, Kensington Pride) litchi Way Chee Kwai Mai Pink) cultivated Sicily. Botryosphaeriaceae Diaporthaceae consistently isolated symptomatic sample...

A simple, rapid and efficient method for isolating genomic DNA from lychee (Litchi chinensis Sonn.) was developed. This modified CTAB protocol include the use of 2 M NaCl, PVP, 5% mercaptoethanol and 80% ethanol in the extraction as well as reducing the centrifugation times during the separation and precipitation of the DNA. Isolated genomic DNA showed high purity and high quantity following re...

Litchi chinensis is the “queen of fruits”, and pollination an essential requirement for fruit set production. The present study was conducted in litchi orchards to diversity/abundance insect visitors, impact on quantitative parameters, different modes pollination. results showed that 75 species during flowering were reported including Hymenoptera, Lepidoptera, Diptera, Coleoptera. In natural po...

Three new pavine N-oxide alkaloids, (-)-isocaryachine-N-oxide B, (+)-caryachine-N-oxide, (-)-caryachine-N-oxide, and a new isoquinoline alkaloid, 6,7-methylenedioxy-N-methylisoquinoline together with 11 known alkaloids were isolated and characterized from the stem bark of Cryptocarya chinensis. The structures of the isolated compounds were determined by spectral methods. The stereochemistry of ...

Instance segmentation of fruit tree canopies from images acquired by unmanned aerial vehicles (UAVs) is significance for the precise management orchards. Although deep learning methods have been widely used in fields feature extraction and classification, there are still phenomena complex data strong dependence on software performances. This paper proposes a learning-based instance method litch...

In the present study, the efficacy of litchi fruit pericarp (LFP) extract (0.5%, 1.0% and 1.5% concentration) in retarding lipid oxidation of cooked sheep meat nuggets was evaluated and compared to butylated hydroxyl toluene (BHT, 100 ppm). The total phenolic content and antioxidant potential of LFP extracts were determined. The thiobarbituric acid reactive substance (TBARS) values were evaluat...
