In this work we develop a novel approach for the automatic recognition of red Fuji apples within a tree canopy using three distinguishable color models in order to achieve automated harvesting. How to select the recognition model is important for the certain intelligent harvester employed to perform in real orchards. The L*a*b color model, HSI (Hue, Saturation and Intensity) color model and LCD...

In this study, the aim is to develop a population model based approach to optimize fruit harvesting strategies with regard to fruit quality and its derived economic value. This approach was applied to the case of tomato fruit harvesting under Vietnamese conditions. Fruit growth and development of tomato (cv. "Savior") was monitored in terms of fruit size and color during both the Vietnamese win...

Color defines one aspect of quality for tomato and tomato products. Carotenoid pigments are responsible for the red and orange colors of tomato fruit, and thus color is also of dietary interest. The aims of this study were (1) to determine the relative importance of field sampling and analytical replication when measuring lycopene and beta-carotene in tomato fruit and (2) to determine the effec...

Anthocyanin concentrations increased in both external and internal tissues of ‘Selva’ strawberries (Fragaria ×ananassa Duch.) stored in air at 5 °C for 10 days, but the increase was lower in fruit stored in air enriched with 10 or 20 kPa CO2. Flesh red color was less intense in CO2 storage than in air storage. Activities of phenylalanine ammonia lyase (PAL) and UDP glucose : flavonoid glucosylt...

Fruit of 85 varieties of Pakistani dates were collected throughout the harvest season. Appropriate Performa was designed to write the scientific and commonly used properties. These properties included fruit color at Khalal stage, shape, size (length & diameter), color & height of perianth, fruit group (soft, semi-dry, dry), edible stage and the micropyle position and split (wide, narrow, deep)....

This study represents the first paper of the effects of growth regulators on the physiochemical and phytochemical properties of the wax apple fruit, a widely cultivated fruit tree in southeast Asia. Net photosynthesis, sucrose phosphate synthase (SPS) activity, peel color, fruit firmness, juice content, pH value, total soluble solids (TSSs), and the sugar acid ratio were all significantly incre...

Morphological studies showed that tree shape in Bitter sweet orange and Yuma citrange was spheroid with spreading growth habit and wide branch angle. Leaves were simple with dark green color, medium size and brevipetiolate in Sour orange while Yuma citrange had trifoliate leaves with medium and green color. Bitter sweet orange had the highest leaf lamina length (10.4 mm) than other rootstocks. ...

The major architectural differences between most Arthropod classes and orders involve variations in the number, type and pattern of body appendages. We have utilized the emerging knowledge of appendage formation in fruit flies to begin to address the developmental and genetic basis of morphological diversity among insects. Butterflies, for example, differ from fruit flies in possessing larval a...

In an effort to develop an inexpensive alternative to vapor-heat insect disinfestation of ‘Kensington’ mango (Mangifera indica Linn.), the effect of postharvest hot water treatments (HWT) on fruit quality was determined. Fruit were given 46C HWT for 30 minutes at a fruit core temperature of 45C either 24 hours after harvest or after various conditioning treatments of 4 to 24 hours at 39 ± 1C in...

Abstract Garifta-merah is one of the mango varieties released by Ministry Agriculture in 2009 with advantage having red-yellow peel when it reaches full maturity. The distinctive taste fruit flesh makes types mangoes favored consumers local and foreign countries. As a new variety, there not much data regarding mango, especially optimal maturity stage to harvest. This study aims determine physic...
