Abstract In this study ameliorative effects of ascorbic acid (0.5 mM) on onion (Allium cepa L. cv. Red Azarshahr) under copper stress (Cu: 6.5 μM) were studied. Fresh weights of leaves and roots were reduced in seven week old plants under excess copper condition. Cu stress also reduced membrane stability index in leaves. There was a considerable increase in H2O2 content and lipid peroxidation i...

considered to be the cleanest liquid fuel, bioethanol can be a reliable alternative to fossil fuels. it is produced by fermentation of sugar components of plant materials. the common onions are considered to be a favorable source of fermentation products as they have high sugar contents as well as contain various nutrients. this study focused on the effective production of ethanol from an endem...

Effects of L-ornithine (150 mg/l) on the germination, seedling growth, mitotic index, chromosome aberrations and micronucleus frequency Allium cepa L. bulbs germinated at 0.125 M salinity were studied. The radicle number group III in medium with ornithine alone as compared to ones I (control) which distilled water medium. But, their germination percentage, length fresh weight statistically same...
