Relationships among cold hardiness, water-soluble protein, anthocyanins, & free sugars in Hedera helix L.
It has been much disputed whether seasonal variations in proteins or in sugars are better related to cold hardiness changes in certain over-wintering plants (for example, 1, 2, 3, 8, 12, 14). But proteins have been difficult to study, since they are not easily extracted from such plants as our native winter-hardy trees. This is because such proteins are often precipitated by vacuolar substances...
متن کاملCold Acclimation of Hedera helix
The light-enhanced production and accumulation of sugars is only one step in the process of cold acclimation in Hedera helix L. var. Thorndale (English ivy). Applications of 2,4-dinitrophenol to plants with different portions exposed to light and dark indicated that the mere presence or accunmulation of the light-generated promoters did not invoke an increase in hardiness. Kinetics of cold accl...
متن کاملSeasonal Variations in Carnosic Acid Content of Rosemary Correlates with Anthocyanins and Soluble Sugars
Seasonal variations may influence the quality and quantity of biologically active ingredients in medicinal plants. Rosemary (Rosmarinus officinalis L.) a member of the Lamiaceae family, contains valuable antioxidant, anticancer and antibacterial substances, including Carnosic acid (CA). Here, the fluctuations of important active compounds present in rosemary leaf extracts collected in Golestan,...
متن کاملThe Role of Light in Cold Acclimation of Hedera helix L. var. Thorndale.
The role of light in cold acclimation of Hedera helix L. var. Thorndale appears to differ from that reported for winter annuals. Although light greatly enhances the degree of hardiness attained, cold acclimation is not obligatorily linked to a light requirement. Photoperiods, varying from 8 to 24 hours, received during the cold acclimation period were equally effective in promoting maximum hard...
