Image/video processing for fruit detection in the tree using hard-coded feature extraction algorithms has shown high accuracy on during recent years. While accurate, these approaches even with high-end hardware are still computationally intensive and too slow real-time systems. This paper details use of deep convolution neural networks architecture based single-stage detectors. Using deep-learning techniques eliminates need hard-code specific features shapes, color and/or other attributes....
Abstract Fruit size is crucial for growers as it influences consumer willingness to buy and the price of fruit. growth along seasons are two parameters that can lead more precise orchard management favoring production sustainability. In this study, a Python-based computer vision system (CVS) sizing apples directly on tree was developed ease fruit tasks. The made consumer-grade depth camera tested at distances among 17 timings throughout season, in Fuji apple orchard. CVS exploited...
The effect of shading (i.e.reduction sunlight availability) on fruit growth physiology has been widely studied in apple (Malus domestica Borkh.), but little knowledge exist about responses to changes the light spectrum.The aim present research was study use colored nets with differential transmission blue (B, 400-500 nm), red (R, 600-700 nm) and far-red (FR, 700-800 spectra physiological associated responses.Three year old 'Fuji' trees were covered 40% photo-selective shade nets, neutral...
The kiwifruit berry is characterized by an early stage of rapid growth, followed a relatively long slow increase in size. Vascular and transpiration flows are the main processes through which water carbon enter/exit fruit, determining daily seasonal changes fruit This work investigates biophysical mechanisms underpinning change growth rate during season.The patterns phloem, xylem in/outflows have been determined at several stages development, two seasons. different were quantified comparing...
This work describes a fruit gauge based on low-cost linear potentiometer interfaced to data-logger, which allows continuous measurement of diameter. The sensor is supported by custom-built stainless steel frame designed be easily applied different size fruits. Highly significant relationships between tension (mV) and displacement (mm) have been found during calibration. average slope this relationship, 5.4 × 10 −3 with standard deviation 5 −5 , was used as conversion coefficient. Temperature...
Solar radiation entering a high-wire tomato greenhouse is mostly intercepted by the top of crop canopy, while role lower leaves diminishes with age, turning them into sink organs rather than sources. Accordingly, defoliation basal widely applied agronomic practice in cultivation management. However, recent increase application supplemental light emitting diode (LED) lighting for high-density production may affect leaves, promoting their source fruit development and growth. The present...
Abstract BACKGROUND Texture is important in the preferences of apple consumers. Of pre‐harvest factors affecting fruit quality and especially texture, altitude subsequent climatic conditions are crucial, determining differences physiological mechanisms growth, ripening stage chemical composition, as demonstrated by several studies. This work applies a detailed sensory‐instrumental protocol developed previous paper to investigate impact altitude, time harvest their cross‐effect on sensory...
SummaryThe effects of innovative techniques for orchard light management on the sensory properties and quality apple (Malus _ domestica Borkh.) fruit were measured using instrumental techniques. In first experiment, 'Rosy Glow' fruit, thinned chemically or by shading, compared. second 'Fuji' grown under five different coloured photo-selective hail nets For efficacy both thinning methods was comparable in terms crop load, no differences perceived between treatments a trained panel, based...
The sustainability of reducing light in apple orchards under well-watered (ww) and water stress (ws) conditions was evaluated for relations, plant gas exchanges, fruit growth, yield determinants, quality over three years. A black (B) 28% shading net compared with two different 50% nets: red (R) white (W). Each combined irrigation regimes (ww ws) based on status. Under ww ws conditions, increasing shade from to not detrimental yield, or Higher improved status regardless regime. could be...
The detection of leaf functionality is pivotal importance for plant scientists from both theoretical and practical point view. Leaves are the sources dry matter food, they sequester CO 2 as well. Under perspective climate change primary resource scarcity (i.e. water, fertilizers soil), assessing photo‐assimilation in a rapid but comprehensive way can be helpful understanding behavior under different environmental conditions managing agricultural practices properly. Several approaches have...
Water scarcity is a major concern in agriculture worldwide. Fruit trees are severely affected by water deprivation terms of growth, fruit yield, and quality. Plant monitoring combined with efficient irrigation pivotal to achieve good quality standards improve agricultural sustainability. This study reports the use vivo sensing technology monitor tree species continuously, real time vivo, through an Organic Electrochemical Transistor (OECT)-based biosensor called Bioristor. The sensor was...
