Oxidative stress responses and root lignification induced by Fe deficiency conditions in pear and quince genotypes.
We analysed Pyrus communis cv. Conference and Cydonia oblonga BA29, differently tolerant to lime-induced chlorosis, to identify the key mechanisms involved in their different performance under Fe deficiency induced by the absence of Fe (-Fe) or by the presence of bicarbonate (+FeBic). Under our experimental conditions, a decrease in root elongation was observed in BA29 under bicarbonate supply....

Iron (Fe) chlorosis is an important nutritional problem in quince trees. But, quince rootstocks differ in their tolerance to Fe deficiency in calcareous soils. Tolerance to Fe deficiency of seedling rootstocks of quince, pear and crataegus and clonal rootstock of quince A was evaluated by exposure to two levels of Fe (3 and 50 µM) in the presence or absence of 10 mM bicarbonate in soilless cult...

15 صفحه اولResponses of Almond Genotypes to Osmotic Stress Induced In Vitro
Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...
متن کاملInteractive of arsenate and phosphate on arsenic-induced oxidative stress in root of Isatis cappadocica Desv.
In present study, growth, arsenic accumulation, and antioxidant responses in root of Isatis cappadocica were investigated in response to application of arsenate and phosphate. Reduction in root dry weights was significant with 1200 µM arsenate and 5 µM phosphate treatments. Phosphate had a steady effect on root dry weight improvement, especially in high arsenate treatments ≥ 200 μM. As concentr...
