Pigment Changes in Parsley Leaves during Storage in Controlled or Ethylene Containing Atmosphere
نویسندگان
چکیده
Pigments were monitored in parsley leaves stored in air, air + 10 ppm GH.,, or 10% O2 + 10% CO2 controlled atmosphere (CA). Chlorophylls a and b, as determined with HPLC, decreased sharply in leaves held in air or air + 10 ppm GH4. The decrease was less in leaves held in 10% O2 and 10% CO2 CA. The oxidized product of chlorophyll a, lo-hydroxychlorophyll a, did not accumulate and chlorophyllide accumulated minimally. Xanthophylls decreased but new pigments, suspected to be esterified xanthophylls, formed with yellowing of leaves. Neither the pathway of Chl degradation or xanthophyll products were altered by GH, or CA.

Background: It was found that, climatic conditions and fruit ripeness are important factor for the occurrence and intensity of superficial scald. 1-MCP is an inhibitor of ethylene action in plants and inhibits many ripening related processes along with the production of ethylene and volatiles. Objective: Apples are often held for several months at low temperature either in air (RA) or in con...

متن کاملThe effects of ethylene, depressed oxygen and elevated carbon dioxide on antioxidant profiles of senescing spinach leaves.
It has been suggested that antioxidants play a role in regulating or modulating senescence dynamics of plant tissues. Ethylene has been shown to promote early plant senescence while controlled atmospheres (CA; reduced O2 levels and elevated CO2 levels) can delay its onset and/or severity. In order to examine the possible importance of various antioxidants in the regulation of senescence, detach...
