Carotenoids in the peel of harvested citrus in creased following treatment with ethylene. Im proved color resulted primarily from an increase in the amount of an orange-red pigment, cryptoxanthin, and a red pigment, jg-citraurin. Tempera ture influenced pigment accumulation. At 65 °F and 75 °F, rapid accumulation of both cryptoxanthin and jg-citraurin resulted in highly colored fruit. At 85 °F,...

fruit productivity and quality of eight years peach and nectarine cultivars (rich lady, ryan sun, ruby diamond and venus) grafted onto cadaman-avimag, viking, atlas, gxn 15, gf 677, mrs 2/5 and nemaguard (control) rootstocks were evaluated. a split plot experimental design was used, with each rootstock/scion combination as an experimental unit. total yield, fruit size distribution, number of fr...

This project deals with the ripeness of oil palm fruit. The current procedure in the palm oil mills is grading the oil palm fruit manually using human graders. This method is subjective and inconsistence because each graders has its own techniques and may vary from each other’s. Hence, it affects the quality and quantity of the oil that can be extracted. In this project, a new model of automate...

Cucumber fruits (Cucumis sativus L., cv. Trópico F1) grown on perlite substrate and NFT (Nutrient Film Technique) were harvested during two seasons (winter and spring) to monitor the effects of climatic conditions and hydroponic growth systems on fruit quality at harvest. The best fruit quality at harvest, as measured by lightness and hue angle parameters, was obtained during the 3 weeks follow...

abstract this study was carried out in japan for evaluation of the relationship between phenolic compounds and skin color indices of 3 apples cultivars including ‘fuji’, ‘jonathan’ and ‘jonagold’, in 2006. in ‘jonathan’, l* (lightness) increased with decreasing red color of skin. in ‘jonagold’, chroma increased with increasing red color. but in ‘fuji’, there was no detectable difference between...

Light is an important environmental factor for fruit development and ripening in pepper plant. Fruit bagging is a significant agrotechnology practiced for the illumination regulation of fruits; some previous researches have shown that fruit bagging could improve the appearance and external quality of fruits and cause them to mature early. However, it would decrease the intrinsic qualities of fr...

A Split Plot experimental design was used, with each rootstock/scion combination as an experimental unit. Total yield, fruit size distribution, number of fr...

Highly colored cranberries are desired for both fresh and juice markets. Berries accumulate more color when allowed to stay on the vines longer. However, early fall frosts often force growers to harvest before the fruit has reached its optimal color. This is especially true for the berries under the canopy. No product is currently available for grower to accelerate the color development in cran...
