Ethylene Production by Satsuma Mandarin Fruit Harvested at the Various Stages of Development

Ethylene Production by Albedo Tissue of Satsuma Mandarin (Citrus unshiu Marc.) Fruit.

Isolated albedo tissue of Satsuma mandarin (Citrus unshiu Marcovitch, cv. Owari) fruit produced a large quantity of ethylene during incubation at 26 C in the dark. When sliced, albedo tissue began producing ethylene at an increasing rate until a maximum was reached after incubation for about 30 hours. Aged albedo discs which were capable of producing ethylene, actively converted l-[U-(14)C]meth...

The effect of rootstocks on sugars, acids, carotenoids, chlorophylls, and ethylene of Satsuma mandarin (Citrus unshiu)

This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Cloning and expression of ethylene receptor ERS1 at various developmental and ripening stages of mango fruit.

Ethylene induces characteristic ripening reactions in climacteric fruits through its binding to histidine-kinase (HK) receptors, activating the expression of ripening genes. Ethylene receptors have been found in Arabidopsis thaliana (Brassicaceae) and some fruits; number and expression patterns differ among species. In mango, only ethylene receptor ETR1 was known. We cloned ERS1 cDNA from mango...

Ethylene Production, Respiration, & Internal Gas Concentrations in Cantaloupe Fruits at Various Stages of Maturity.

In studying the relationship between ethylene production and the climacteric rise in respiration exhibited by ripening fruits, it was not possible to determine when ethylene production begins until the advent of gas chromatography. This technique makes available quantitative measurement of ethylene concentrations at or below the threshold of physiological activity. Burg and Thimann (3, 4) were ...
