The main issue of vison-based automatic harvesting manipulators is the difficulty in the correct fruit identification in the images under natural lighting conditions. Mostly, the solution has been based on a linear combination of color components in the multispectral images. However, the results have not reached a satisfactory level. To overcome this issue, this paper proposes a robust nonlinea...

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...

The word “pumpkin” is derived from the Latin word pepo, which is a botanical term for fruit with a hard rind and fleshy interior. The commonly used scientific name for pumpkins is Cucurbita pepo. But some other cucurbits, such as Cucurbita moschata (e.g., ‘Dickenson’ and ‘Libby Select’, known as processing pumpkin) (Figure 1, B) and Cucurbita maxima, which are winter squash, are also known as p...

‘Perfection’ apricot fruit (Prunus armeniaca L.) were treated with 1 ml l 1-methylcyclopropene (MCP) for 4 h at 20°C then stored at 0 or 20°C. The onset of ethylene production was delayed and respiration rate was reduced following MCP treatment. MCP treatment resulted in less firmness and titratable acidity loss during storage at both temperatures and delayed production of volatile alcohols and...

harvesting of sour cherries is very difficult task which is done either by machine or hand. in order to facilitate fruits harvesting ethephone with different densities is used. in this research work iranian produced ethephone with density of 1.18 g/cm3 and england produced ethephone with density of 1.45 g/cm3 was utilized with different concentration (0, 150, 225 and 300) in a 2×4 factorial exp...

in this research, kiwifruits (hayward) were selected in two mass ranges (large and small). they were placed in one-liter glass bottles in the vicinity of the polyethylene sachets containing potassium permanganate nano-zeolite (0, 0.2, 0.4 and 0.8 g) and were stored in a germinator (5°c temperature and 30% relative humidity). then, the physicochemical properties of the fruits (soluble solid cont...

The fruit ripening developmental program is specific to plants bearing fleshy fruits and dramatically changes fruit characteristics, including color, aroma, and texture. The tomato (Solanum lycopersicum) MADS box transcription factor RIPENING INHIBITOR (RIN), one of the earliest acting ripening regulators, is required for both ethylene-dependent and -independent ripening regulatory pathways. Re...

Wild Mediterranean fruit fly females, Ceratitis capitata (Wiedemann), from an essentially monophagous population on the island of Hawaii were exposed to natural mock orange (Murraya panieulata) or sweet orange (Citrus sinensis) host fruit hung from branches of potted trees for 3-day periods in field enclosures. Subsequently, when flies were released individually onto potted trees harboring one ...

A cDNA clone from tomato fruit encodes a protein with strong homology with the rab11/YPT3 class of small GTPases that is thought to be involved in the control of protein trafficking within cells. The gene, LeRab11a, showed a pattern consistent with a single copy in DNA gel blots. The corresponding mRNA was developmentally regulated during fruit ripening, and its expression was inhibited in seve...
