Plant 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 کاملUltrastructural changes of the egg apparatus associated with fertilisation of natural tetraploid Trifolium pratense L. (Fabaceae).
The aim of this study is to describe the ultrastructural changes of the egg apparatus associated with fertilisation of the natural tetraploid Trifolium pratense. The pollen tube enters one of the synergids through the filliform apparatus from the micropyle. Before the entry of the pollen tube into the embryo sac, one of the synergids begins to degenerate, as indicated by increased electron dens...
متن کاملTrifolium pratense L. as a potential natural antioxidant.
The essential oils of three different growth stages of Trifolium pratense L. (TP1, TP2 and TP3) were investigated by gas chromatography-mass spectrometry and tested for their antioxidant and antimicrobial activities. The highest content of volatile compounds was found in the essential oil sample TP1, where terpenes such as β-myrcene (4.55%), p-cymene (3.59%), limonene (0.86%), tetrahydroionone ...
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 ...
متن کاملRed Clover (Trifolium pratense)
Brief Background: Red clover is a legume, which like soy contains "phytoestrogens" (plant-based compounds structurally similar to estradiol, capable of binding to estrogen receptors as an agonist or antagonist). Red clover was traditionally used to treat asthma, pertussis, cancer, and gout. In modern times, isoflavone extracts of red clover are most often used to treat menopausal symptoms, as a...
