A method was developed for the simultaneous determination of residues of pirimicarb (I) and its desmethylformamido (II) and desmethyl (III) metabolites in plums, peas, green beans, broad beans, carrots, and swedes. The compounds were extracted with ethyl acetate and determined, without cleanup, by reversed-phase liquid chromatography and electrospray mass spectrometry (MS). MS and MS/MS were us...

In-depth characterization of the genetic diversity and population structure wild relatives is paramount importance for improvement biodiversity conservation, particularly crucial when crops are endangered. In this study, we sampled Alpine plum (Briançon apricot) Prunus brigantina Vill. across its natural distribution in French Alps, where populations severely fragmented size strongly impacted b...

Bacterial spot and canker of stone fruits is a multifaceted disease caused by Xanthomonas arboricola pv. pruni. The disease has a more significant economic impact on Japanese plums, peach and nectarines. Estimated crop losses can reach over 10,000 €/ha in epidemic years in modern commercial plum orchards. Disease establishment and pattern of the epidemics are strongly influenced by prevailing c...

Abstract The aim of this study was to determine the effect temperature and time convective drying on content fructooligosaccharides (FOS) in apples, plums strawberries which FOS had been introduced by osmoconcentration. share oligosaccharides total sugars analyzed. In apple tissue, were stable range 40–80 °C during for up 8 h. Convective osmotically dehydrated caused losses; retention after h a...

Green plums have produced significant economic benefits because of their nutritional and medicinal value. However, green are affected by factors such as plant diseases insect pests during growth, picking, transportation, storage, which seriously affect the quality products, reducing At present, in detection plum defects, some researchers applied deep learning to identify surface defects. recogn...

Rain spots on green plum are superficial micro-defects. Defect detection based a two-dimensional image is easily influenced by factors such as placement position and light prone to misjudgment omission, which the main problems affecting accuracy of defect screening plum. In this paper, using computer vision technology, an improved structure from motion (SFM) patch-based multi-view stereo (PMVS)...

Green plums are a characteristic fruit resource in China, with long history of cultivation. Many surface defects will appear the growth, transportation and preservation green which seriously affect processing quality by-products. The existing manual sorting method is limited by experience workers. It difficult to ensure speed detection. Therefore, formation automatic detection great significanc...
