Mature avocado fruit (Persea americana Mill. cvs ‘Ettinger’, ‘Hass’, ‘Reed’ and ‘Fuerte’), harvested during the commercial harvesting season, were treated with various concentrations of 1-methylcyclopropene (1-MCP) for 24 h at 22°C and after ventilation, were exposed to 300 ml l ethylene for 24 h at 22°C. The fruit were then stored at 22°C in ethylene-free air for ripening assessment. Ethylene ...

Ethephon (2-chloroethylphosphonic acid) was applied to single cluster greenhouse tomato crops (1000 ppm) at the green mature stage of fruit development or when 35% of the plants had fruits at the breaker stage. Fruits were harvested at the pink stage. Untreated fruit were harvested from 95 to 116 days after sowing whereas fruit from the green mature ethephon treatment were harvested from 92 to ...

Cultivated pepper (Capsicum annuum) is a phenotypically diverse species grown throughout the world. Wild and landrace peppers are typically small-fruited and pungent, but contain many important traits such as insect and disease resistance. Cultivated peppers vary dramatically in size, shape, pungency, and color, and often lack resistance traits. Fruit characteristics (e.g. shape and pericarp th...

Skin color is a key quality attribute of fruits and how to improve fruit coloration has long been a major concern. 5-Aminolevulinic acid (ALA), a natural plant growth regulator, can significantly increase anthocyanin accumulation in fruit skin and therefore effectively improve coloration of many fruits, including apple. However, the molecular mechanism how ALA stimulates anthocyanin accumulatio...

In this paper an appearance-based statistical approach for localization and classification of 3-D objects in 2-D color images with real heterogeneous backgrounds is presented. The object feature extraction is done separately for the red, green, and blue channel. We compute six dimensional local feature vectors directly from pixel values in the images using wavelet multiresolution analysis. The ...

The nature of papaya fruits is intently connected with their physical characteristics. Changes during aging are critical, yet uncontrolled ripening procedure can prompt fast degradation quality. Despite the myriads problems storage and transportation or distribution, it imperative to control so as reduce losses maximize profit. A 4x2 factorial experiment in a completely randomized design was ca...

In this study, the effects of bagging treatment on fruit appearance and internal quality, including shape index, single weight, vitamin C, soluble solids, titratable acid, chlorophyll carotenoid content, were studied by using ‘Donghong’ kiwifruit as experimental material. Meanwhile, pesticide residues bagged non-bagged (NB) compared analyzed. Results showed that pericarp color is lighter in gre...

the physical and physiological characteristics of sarawak pineapple were studied at five different stages of growth from one to five months after anthesis. changes in fruit length, diameter, pulp color, pulp firmness, ph, total soluble solids, titratable acidity, ascorbic acid content and antioxidant activity were monitored. the sarawak pineapple exhibited a sigmoid growth pattern during fruit ...
