Differential responses of two Iranian rice cultivars to arsenite toxicity
Arsenic (As) is a toxic metalloid which is usually found in rice fields as a contamination and has negative effects on the plant growth and reduces the crop yield. Similar to heavy metals, the deleterious effects of As may be due to, at least in part, the amount of absorbed As and disturbance of the plant water status. I...
متن کاملPolyamines as modulators of salt tolerance in rice cultivars.
The effect of NaCl on the endogenous levels of diamine, putrescine and polyamines, spermidine and spermine, was studied in the shoot system of salt-tolerant and salt-sensitive lines of rice (Oryza sativa L.) cultivars during three growth stages. Salt stress increased the levels of diamine and polyamine in varying degrees among nine rice cultivars investigated. Salt tolerant AU1, Co43, and CSC1 ...
متن کاملHigh Serum Ferritin Concentrations in Polycystic Ovary Syndrome Is Not Related to Insulin Resistance
OBJECTIVE: Some data are available on the association between components of the insulin resistance syndrome and serum ferritin. Insulin resistance is observed in patients with polycystic ovary syndrome (PCOS) We hypothesize that body iron stores might be increased in these women. MATERIALS AND METHODS: Two hundred and six people (103 PCOS patients and 103 healthy women who were matched for a...
متن کاملMetabolic variation in rice cultivars of contrasting salt tolerance and its improvement by zinc in sodic soil.
The severity of Zn deficiency increased with increase in soil exchangeable sodium percentage (ESP) with salt sensitive variety M1-48 scoring 6 at ESP 62 as against only score 3 by salt tolerant variety Pokkali under similar soil conditions. Strikingly, zinc contents were much higher in salt tolerant variety than in salt sensitive one. Zinc application increased zinc concentration in the roots b...
متن کاملSalt Tolerance in Rice Cultivars and Changes in Sodium and Potassium Ions
Salinity is an environmental stress that limits growth and development in plants. Due to high salinity in Khuzestan soils it is necessary to identify cultivars with appropriate yield that are compatible with Khuzestan conditions. This experiment was done to evaluate three rice cultivars for salinity tolerance at seedling stage by measuring the absorption of sodium and potassium ions and the rat...
