Defense response of pumpkin rootstock to cadmium
نویسندگان
چکیده
Cadmium (Cd) is a heavy metal, which will pollute the soil and affect growth development of plants. Grafting can alleviate toxicity metals. Pumpkin (Cucurbita moschata Duch.) commonly-used grafting rootstock for melon plants, breeding with cadmium tolerance plays vital role in safe production In this study, pumpkin MB3, FB1 their hybrid F1 ZF1 were used as experimental materials. The substrate culture was applied under conditions (8, 16, 24 mg/L), defense response to studied, free stress control. results indicated that stress, seedlings inhibited, but compared control, Cd promoted plant height ZF1. determination content each part showed accumulation ability roots higher than parents, transfer coefficient shoot low, reduced concentration leaves, improved photosynthetic assimilation leaves seedlings, enhanced activities antioxidant enzymes (SOD, POD, CAT). Root activity root scanner had least damage MB3 parents. distribution systems subcellular initiated membrane protective enzyme, relieved membrane, through cell wall blocked its entrance cytoplasm. This study provides theoretical foundation breed cadmium-tolerant rootstocks

Response of Badami-Zarand Pistachio Rootstock to Salinity Stress
Salinity is one of the most important problems that restrict cultivation of crops in arid and semi-arid regions. Pistachio (Pistacia vera L.) is one of the most important trees that grow in these restricts. In this greenhouse study, the effects of salinity on growth of pistachio rootstock Badami evaluated. Seedlings were grown in plastic bags containing perlite. Salinity was imposed, by adding ...
متن کاملGrowth and Chemical Composition of Pistachio Seedling Rootstock in Response to Exogenous Polyamines under Salinity Stress
In order to evaluate responses of a pistachio seedling rootstock (Pistacia vera L. cv. Ghazvini) to NaCl induced salinity stress and potential protective role of exogenous spermine and spermidine on NaCl induced salinity stress, a greenhouse experiment was conducted during growing season of 2009. The NaCl treatments, involving 800, 1600, and 3200 mg NaCl per Kg of soil for 90 days, suppressed g...
متن کاملEvaluation of Biochemical Response and Defense Mechanism of Wheat Antioxidant Enzymes to Salinity Stress
Understanding the reaction form and biochemical response of wheat cultivars about the salinity stress can help to better understand the defense mechanisms and identify the indicators and biomarkers of tolerance screening for salinity stress in this strategic plant and other field crop. For this purpose, biochemical traits related to salinity tolerance of wheat cultivars were evaluated as a f...
متن کاملEnzymatic antioxidant defense in isolated rat hepatocytes exposed to cadmium.
The aim of the study was the evaluation of cadmium effects on the activity of antioxidant enzymes in rat hepatocytes. The studies were conducted with isolated rat hepatocytes incubated for 1 or 2 hours in a modified (deprived of carbonates with phosphates) Williams' E medium (MWE) in the presence of cadmium chloride (25, 50 and 200 microM). Hepatocytes incubated in the MWE medium without cadmiu...
