A simple and rapid method using high performance liquid chromatography (HPLC) was developed to determine levels of adenosine triphosphate (ATP), adenosine diphosphate (ADP) and adenosine monophosphate (AMP) in litchi fruit pericarp tissue. This HPLC method used acetonitrile gradient elution and shortened the time required for determinations of adenosine phosphates. This analysis exhibited good ...

'Guiwei' litchi fruit were treated with 5 ga.i. L(-1) apple polyphenols (APP) and then stored at 25°C to investigate the effects on pericarp browning. APP treatment effectively reduced pericarp browning and retarded the loss of red colour. APP-treated fruit exhibited higher levels of anthocyanins and cyanidin-3-rutinoside, which correlated with suppressed anthocyanase activity. APP treatment al...

The purpose of the present study was to examine whether rejection of novel foods during infancy predicted child behavioral and parent-reported neophobia at 4.5 years of age. Data for the present study were drawn from a longitudinal study following individuals (n = 82) from infancy through early childhood. At 6 and 12 months of age, the infants tasted a novel food (green beans, hummus, or cottag...

In this study, we have developed a prototype of a portable electronic nose (E-Nose) comprising a sensor array of eight commercially available sensors, a data acquisition interface PCB, and a microprocessor. Verification software was developed to verify system functions. Experimental results indicate that the proposed system prototype is able to identify the fragrance of three fruits, namely lem...

Light is a key environmental factor that affects anthocyanin biosynthesis. To enhance our understanding of the mechanisms involved in light-regulated anthocyanin biosynthesis in the pericarp of litchi, we performed transcriptomic analyses on the basis of Illumina sequencing. Fruit clusters were bagged with double-layer Kraft paper bags at 42 days after anthesis. The bags were removed after 2 we...

Calcium (Ca) deficiency in fruit causes various physiological disorders leading to quality loss. However, disorders related to Ca deficiency are not simply caused by a shortage of calcium supply. Ca distribution is also an important relation. This study examined Ca distribution pattern in fruit and pedicel in litchi (Litchi chinensis Sonn.) and the influence of Ca channel inhibitor La3+ on frui...

The present study was carried out in 2021-2022, to estimate the socio-economic characteristics and Knowledge level of Litchi growers regarding Integrated Pest Management (IPM) practices. conducted Pathankot Gurdaspur districts Punjab India. From each district, two blocks were selected having maximum number litchi from selected, 25 respondents randomly procured list horticulture department make ...

Accurate and reliable fruit detection in the orchard environment is an important step for yield estimation robotic harvesting. However, existing methods often target large relatively sparse fruits, but they cannot provide a good solution small densely distributed fruits. This paper proposes YOLOv3-Litchi model based on YOLOv3 to detect litchi fruits visual scenes. We adjusted prediction scale r...
