“…Another group, which included the cultivated varieties K3, cv. 17, Malti 28, Malti 29, and Malti 30, clustered, instead, with the Spanish and Lebanese varieties, including the very popular polyclonal Baladi variety [41]. This cluster also appeared to be related to the medium/large size of the drupes, including varieties of different origins (Spain, Greece, Italy, etc.)…”

The genetic diversity of the ancient autochthonous olive trees on the Maltese islands and the relationship with the wild forms growing in marginal areas of the island (57 samples), as well as with the most widespread cultivars in the Mediterranean region (150 references), were investigated by genetic analysis with 10 SSR markers. The analysis revealed a high genetic diversity of Maltese germplasm, totaling 84 alleles and a Shannon information index (I) of 1.08. All samples from the upper and the lower part of the crown of the Bidni trees belonged to the same genotype, suggesting that there was no secondary top-grafting of the branches. The Bidni trees showed close relationships with the local wild germplasm, suggesting that the oleaster population played a role in the selection of the Bidni variety. Genetic similarities were also found between Maltese cultivars and several Italian varieties including accessions putatively resistant to the bacterium Xylella fastidiosa, which has recently emerged in the Apulia region (Italy) and has caused severe epidemics on olive trees over the last decade.

“…With the expansion of the agricultural scale, production and management are gradually standardized (Jin and Zhou, 2011). Fortunately, the planting of yellow peach (Miaoxi), loquat (Lanxi), sweet spring tangelo (Qingyuan) and pear (Haining) has gradually shifted from local small-scale farmers to commercial planting, mainly due to the obvious price advantage, and high-quality fruits have high sales potential in the market (Chalak et al, 2014).…”

Miaoxi yellow peach, lanxi loquat, qingyuan sweet spring tangelo and haining pear are characteristic fruits in Zhejiang Province, China. This study investigated the levels of pesticides in these fruits in Zhengjiang Province, China, along with the associated risk of dietary exposure for consumer. In total, 25 pesticides were detected in the 68 samples. The pesticide detection rate of the samples was 95.59%, and the level of prochloraz in a pear sample was found to be higher than the maximum residue limit (MRL) in China. Overall, the pesticide residues were very low, and residue levels ranged from 0.001 to 1.06 mg/kg, of which 80.88% simultaneously occurred with 2–8 mixed residues. Acetamiprid (54.55%), carbendazim (64.71%), prochloraz (94.74%) and pyraclostrobin (85.71%) had the highest detection rate in the four fruits, respectively. A risk assessment of human exposure to pesticides via the intake of the four fruit types was performed, and the chronic intake risk (HQc) and acute intake risk (HQa) of a single pesticide and the hazard index (HI) of the mixture of pesticides for adults and children from the four fruit types were found to be less than 1, the exposure assessment showed that the levels of pesticides in the four fruit types were safe for human consumption. In addition, the quality of the four fruit types was analyzed and found to be not stable enough. We suggest strengthening standardized planting and management technology to improve product quality and safety, in particular, cultivators should use pesticides reasonably and control the pre-harvest interval (PHI) in order to better protect consumer health.

“…It is an important fruit tree in horticulture and in green space in the urban environment and is adapted to the Mediterranean region, especially hot and humid climates. This tree is commercially cultivated for fruit production and grown as an ornamental plant in Asia (India, Japan and Pakistan), Australia, Mediterranean countries (Greece, Italy, Israel, Spain and Turkey), South America (Brazil, Venezuela) and the United States (Badenes et al, 2000; Chalak et al, 2014). In Iran, the northern provinces, such as Gilan, and Fars Province in the south are the central regions of loquat production (Gharaghani et al, 2015).…”

Loquat (Eriobotrya japonica) is a subtropical evergreen plant, important in terms of both horticulture and green space in the urban environment. In recent years, symptoms of branch and trunk canker, dieback and decline have been observed in the main cultivation areas of this tree in Iran. To study the aetiology of loquat canker in Fars Province, branches and trunks of loquat trees with disease symptoms were sampled from 2018 to 2019. Several isolates of an unknown Paramicrosphaeropsis species (Didymellaceae, Pleosporales, Dothideomycetes) were recovered from the trunks and branches of infected loquat trees. Phylogenetic analysis of the isolates based on a multigene phylogeny of the ribosomal internal transcribed spacer (ITS), partial β‐tubulin gene (tub2) and the second‐largest subunit of RNA polymerase II (rpb2) loci revealed that the isolates belonged to a new taxon, Paramicrosphaeropsis eriobotryae sp. nov. Pathogenicity tests revealed that this species was able to cause canker, trunk flaking, dieback, decline, leaf yellowing, defoliation and growth reduction in loquat trees. A host range evaluation on detached branches of some important horticultural trees occurring adjacent to loquat tree orchards of Fars Province showed that P. eriobotryae might have a broader host range, as it was also able to infect almond and olive trees.
