Oppositional Allelism in Diploid and Autotetraploid Trifolium Hybridum L.
HE selfand cross-incompatibilities of a number of obligately cross-polliT nated species of flowering plants are genetically determined by series of multiple oppositional alleles. The oppositional or personate incompatibility system was first described, with substantiating data, by EAST and MANGELSDORF (1925) for Nicotiana species. The existence of oppositional alleles has been subsequently demo...
متن کاملPlant regeneration of natural tetraploid Trifolium pratense L
The regeneration of natural tetraploid T. pratense, originated from Erzurum-Turkey, is reported in this study. This plant has low seed setting and hard seed problems due to polyploidy. Hypocotyl, cotyledon, apical meristems, epicotyl and young primary leaves were inoculated on MS and PC-L2 media containing different concentrations of BAP and NAA as growth regulators. The best shoot formation ha...
متن کاملA study of genetic diversity in Trifolium hybridum varieties using morphological characters and ISSR markers
The nutritive value of alsike clover (Trifolium hybridum L.) is slightly lower than that of red and white clovers; however, it exhibits some advantages – persists longer in a sward, performs well on acid and wet soils, suits for forage and silage production, can be used as green manure, and is a melliferous plant. With declining liming volumes, the soils are rapidly acidifying, which may result...
متن کاملEffects of Extracts from Trifolium medium L. and Trifolium pratense L. on Development of Estrogen Deficiency-Induced Osteoporosis in Rats
Some plant species belonging to Trifolium L. genus are a source of isoflavones considered to exert phytoestrogenic activities. The aim of the present study was to examine the effects of standardized extract obtained from aerial parts of Trifolium medium L., in comparison with the extract of Trifolium pratense L., on the development of estrogen deficiency-induced osteoporosis in rats. Both Trifo...
متن کاملAntioxidant profile of Trifolium pratense L.
In order to examine the antioxidant properties of five different extracts of Trifolium pratense L. (Leguminosae) leaves, various assays which measure free radical scavenging ability were carried out: 1,1-diphenyl-2-picrylhydrazyl, hydroxyl, superoxide anion and nitric oxide radical scavenger capacity tests and lipid peroxidation assay. In all of the tests, only the H2O and (to some extent) the ...
