pomegranate is native to subtropical regions of iran. losses of horticultural products are a major problem in the postharvest chain. in this experiment, six different wrapping (polyethylene and paper covering), chemical (calcium chloride and wax) and thermal (4 °c and outdoor) treatments were applied on the fruits of pomegranate cv shirin kolbad and some physicochemical properties were measured...

irrigation. The idea was to build 100 m of catchment area, and two concrete water storage tanks and irrigate one mu (1/15 hectare) of courtyard land devoted to cash crop production. In practice, the 1-2-1 program focused on building water tanks for household use, with roofs and courtyards serving as the principal catchment surfaces that channel water into the tank. County and township governmen...

Abstract The appearance of fruit color and texture avocado is a quality parameter commonly used by consumers when choosing the fruit, they buy. Intention to repurchases could be determined fruit’s internal properties, such as taste associated with volatile organic compound (VOC). will decrease after harvesting. It also susceptible mechanical damage during harvest post-harvest handling. This res...

Apples should be quickly and correctly detected from their surroundings for the apple harvesting robot. The basic color feature was extracted from FuJi apple tree images and analyzed by the statistical analysis method. Accordingly, a new apple detection method was proposed to position the centroid of picking apples. The color difference was used to segment apples from their surroundings. Then t...

At present, Camellia oleifera fruit harvesting relies on manual labor with low efficiency, while mechanized could result in bud damage because flowering and fruiting are synchronized. As a prerequisite, rapid detection identification urgently needed for high accuracy efficiency simple models to realize selective intelligent harvesting. In this paper, lightweight algorithm YOLOv5s-Camellia based...

The orientation of this research was to evaluate the classic parameters regarding the external and internal quality of tomato fruits cv. 'Brilliant' at different stages of maturity and to define the dynamics of their changes during the ripening in storage at 18 C. Principal component analysis (PCA) and multivariate canonical discriminant analysis (DA) were used to classify tomato samples accor...

Fruits of angiosperms evolved intricate regulatory machinery for sensorial attributes and storage quality after harvesting. Organic acid composition of storage organs forms the molecular and biochemical basis of organoleptic and nutritional qualities with metabolic specialization. Of these, oxalic acid (OA), determines the post-harvest quality in fruits. Tomato (Solanum lycopersicum) fruit has ...

    Different dates for apples fruit harvest (Malus domestica Borkh. Cv. Fuji) were studied to determine physiochemical changes during the storage. Fuji apples were harvested from 9 September till 23 October, at five different times and stored at 0±0.5 °C and 95% relative humidity for 120 days. To determine the best harvest date for maximum quality and storability, physical and chemical paramet...

Harvest-aid platforms are used in modern orchards to improve manual harvesting efficiency, safety, and ergonomics. Typically, workers stand at pre-set heights on a platform’s multi-level deck, each worker harvests fruits inside canopy zone that is defined by the lowest highest reach of worker’s arms. However, fruit distributions non-uniform, picking speeds vary, thus generating mismatch between...
