Some of the heaviest losses of thin skinned avocado fruit are due to endspots, a name applied by COIT (1) to the type of spoilage that affects mature fruits on the tree. In end-spotted fruit the larger end gradually withers and dries and in some cases the cracking may proceed until the seed is exposed. In another type of end-spot called "speckles," small, dark spots occur as dry, depressed area...

Residents of the Red River Delta region of northern Vietnam have a long tradition of eating raw fish. Fish-borne zoonotic trematodes (FZTs) are estimated to infect ≈1 million persons in Vietnam. It remains uncertain at what stages in the aquaculture production cycle fish become infected with FZTs. Newly hatched fish (fry) from 8 hatcheries and juveniles from 27 nurseries were therefore examined...

This paper presents a novel multi-sensor framework to efficiently identify, track, localise and map every piece of fruit in a commercial mango orchard. A multiple viewpoint approach is used to solve the problem of occlusion, thus avoiding the need for labour-intensive field calibration to estimate actual yield. Fruit are detected in images using a state-of-the-art faster R-CNN detector, and pai...

Input requirements in an orchard vary in space and time due to the variability of climate, soil and plant growth. Measurements were carried out in Prunus domestica (plum) orchard in the Werder fruit production area in Brandenburg, Germany. Soil zones in the orchard were identified by means of electrical conductivity. Plant data were captured on the tree and organ level: laser-scanner hits show ...

Mango, a tropical fruit of great economic importance, is generally harvested green and then commercialised after a period of storage. Unfortunately, the final quality of mango batches is highly heterogeneous, in fruit size as well as in gustatory quality and postharvest behaviour. A large amount of knowledge has been gathered on the effects of the maturity stage at harvest and postharvest condi...

Trees have always been important as natural entities carrying a strong symbolic and metaphorical weight, not to mention their practical uses. Therefore, words and their gender, used to name natural entities as important as trees and particularly fruit-trees and their fruits, are also important. Starting from the finding that Portuguese and Mirandese, the second official spoken language of Portu...

BACKGROUND Care procedures for preventing neonatal diseases are carried out according to nurseries' traditions and may be not consistent with the evidence based medicine issues. METHODS A multi-centric survey was conducted in 2 Regions located in NW Italy (Piedmont and Aosta Valley) in order to collect information on some healthy newborn care procedures. During 2001, a questionnaire was sent ...

The rate and duration of apple fruit growth, cell division, and cell expansion, were considered in relation to within-tree factors affecting them. Fruit size at harvest was found to be related to the position of fruit on the spur, seed number, spur size, number of fruits set on the spur, and the date of flowering. The position of fruit on the spur, and spur size, were related to blossom size, b...

This work proposes the development of an embedded real-time fruit detection system for future automatic fruit harvesting. The proposed embedded system is based on an ARM Cortex-M4 (STM32F407VGT6) processor and an Omnivision OV7670 color camera. The future goal of this embedded vision system will be to control a robotized arm to automatically select and pick some fruit directly from the tree. Th...

To better understand the fine-scale spatial dynamics of brown rot disease and corresponding fungal genotypes, we analyzed three-dimensional spatial patterns of pre-harvest fruit rot caused by Monilinia fructicola in individual peach tree canopies and developed microsatellite markers for canopy-level population genetics analyses. Using a magnetic digitizer, high-resolution maps of fruit rot deve...
