Evaluation of analgesic, anti-inflammatory, anti-depressant and anti-coagulant properties of Lactuca sativa (CV. Grand Rapids) plant tissues and cell suspension in rats
BACKGROUND Lactuca sativa (lettuce) has been traditionally used for relieving pain, inflammation, stomach problems including indigestion and lack of appetite. Moreover, the therapeutic significance of L. sativa includes its anticonvulsant, sedative-hypnotic and antioxidant properties. METHODS In the present study, the MC (methanol and chloroform; 1:1) and aqueous extracts of seed and leaf alo...
متن کاملInheritance of Seed Color in Lactuca Sativa^
The mature fruit of lettuce is an achene or naked seed, the color of which is determined by the color of its pericarp. The pigments that give the seed its particular color seem to be localized in the pericarp tissues.^ The mode of inheritance of seed color is of immediate practical importance to those breeding lettuce for disease resistance, climatic adaptation, and desirable commercial charact...
متن کاملStimulation of lettuce seed germination by ethylene.
Ethylene increased the germination of freshly imbibed lettuce (Lactuca sativa L. var. Grand Rapids) seeds. Seeds receiving either red or far-red light or darkness all showed a positive response to the gas. However, ethylene was apparently without effect on dormant seeds, those which failed to germinate after an initial red or far-red treatment. Carbon dioxide, which often acts as a competitive ...
متن کاملEffects of Germination-promoting Substances Given in Conjunction with Red Light on the Phytochrome-mediated Germination of Dormant Lettuce Seeds (Lactuca sativa L.).
Ethylene or thiourea can substitute for gibberellic acid but not for red light in breaking the secondary dormancy induced by extended dark storage of fully hydrated lettuce seeds (Lactuca sativa cv. Grand Rapids). After 10 days of storage, ethylene, thiourea, or gibberellic acid applied either separately or in any combination in conjunction with red light induced near maximal germination. When ...
متن کاملInhibition of lettuce seed germination by cycloheximide and chloramphenicol is alleviated by kinetin and oxygen.
Kinetin alleviates cycloheximide inhibition and oxygen alleviates chloramphenicol inibition of germination of lettuce seeds (Lactuca sativa L. cv Grand Rapids). The effect is not due to increased but rather a substitution for protein synthesis. A cytokinin and energy supply appear prime requirements for germination.
