-
(1998)Stress, pathogens or insects induce profound changes in the expression of the chemical constituents of plants. Some of these changes could be adaptations to the new conditions or the expression of new defensive characteristics. ...
-
(1989)The concentration of proline was found to be similar in the epidermis, the vascular bundles and mesophyll parenchyma protoplasts of barley seedlings. In stressed leaves, proline was accumulated mainly in the vascular bundles ...
-
(1995)To compare the effects of aphid infestation with some effects of wounding and drought-stress, several physiological parameters and metabolite concentrations were measured in infested, mechanically wounded or water-stressed ...
-
(Kluwer Academic/Plenum Publishers, 1999)Common Solanum glycosides were tested against a non-Solanum pest, the greenbug, Schizaphis graminum, fed by artificial diet supplemented with the tested compounds. In contrast with the potato aphid Macrosiphum euphorbiae, ...
-
(2001)The purpose of this work was to investigate whether ethylene is involved in the oxidative and defensive responses of barley to the aphids Schizaphis graminum (biotype C) and Rhopalophum padi. The effect of aphid infestation ...
-
(Pergamon-Elsevier, 1987)Water deficit increased susceptibility of barley to the aphid Schizaphis graminum. Proline and glycine-betaine accumulated in the stressed plants. These compounds were incorporated into artificial diets to test their effects ...
-
(1987)The gramine content in different barley cultivars was not changed under water stress. Proline and glycine-betaine increased as plant water potential decreased. The population growth rate of the aphids Schizaphis graminum ...
-
(2001)Peroxidase enzymes have been found in soluble, ionically bound, and covalently bound forms and have been implicated in several physiological processes in plants. This paper investigates the effect of aphid infestation ...
-
(2003)It has been suggested that salicylic acid (SA) is a signal in acquired resistance to pathogens in several plants. Also, it has been suggested that infestation of plants causes an increase in the activity of phenylalanine ...
-
(1983)2,4‐Dihydroxy‐7‐methoxy‐1,4‐benzoxazin‐3‐one (DIMBOA), the main hydroxamic acid isolated from maize extracts, increased the mortality of Schizaphis graminum when fed in artificial diets. Electrically‐monitored feeding ...
