environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...
to study the effect of sucrose and calcium chloride on the quality and longevity of cut flower of rose cv. varlon, this experiment was conducted at the faculty of agriculture, zanjan university, zanjan, iran, in 2007. cut flowers were received from mahallat ornamental plants and flowers research station. experimental factors included: sucrose at four levels (0, 40, 80 and 100 mg/l) and calcium ...
the production of reactive oxygen species (ros) in plants under low temperature stress cause damage to plants. in order to evaluate of antioxidant responses of page mandarin young trees (two years old) on different rootstocks under low temperatures, an experiment was conducted in a factorial plan based on completely randomized design. treatment of temperatures were at seven levels include 9, 6,...
in this study, the winter cold tolerance of seven strawberry cultivars was evaluated using a rcbd design with a split plot arrangement at bu-ali sina university in 2014. after exposure of plants to low temperatures (+4, -5, -10, -15, -20 and -25oc), the values of electrolyte leakage, index of freeze injury, rwc, total chlorophyll and chlorophyll fluorescence parameters (f0, fm, fv and fv/fm) we...
Water and nitrogen are two of the most important factors for plant growth and development. However, little is known about effects of N on water translocation between connected bamboo ramets. We performed experiment connected Indocalamus decorus ramets in adjacent pots with different soil water contents and three N levels. We determined antioxidase activities, concentration of osmotic adjustment...
the present study was conducted to evaluate the effect of ascorbic acid (asa) as an important antioxidant in alleviation of salt damage in oregano (origanum majorana l.). this research work was carried out at the research greenhouse of ferdowsi university of mashhad. foliar application of asa (0, 100, 200 mg/l) was carried out on the plants that were under salt stresses of 0, 50, 100 and 150 mm...
Replacing organic liquid electrolytes with solid electrolytes has led to a new perspective on batteries, enabling high-energy battery chemistry with intrinsically safe cell designs. However, most solid/gel electrolytes are easily deformed; under extreme deformation, leakage and/or short-circuiting can occur. Here, we report a novel magneto-rheological electrolyte (MR electrolyte) that responds ...
abstract this experiment was carried out to determine the effects of proline and ascorbic acid on chilling injury, electrolyte leakage, lipid peroxidation, peroxide hydrogen and antioxidant enzymes activity of thompson grape (vitis vinifera l.) fruit. grape fruits were treated by 0 (control), 250 and 500 µm proline and 0 (control), 2 and 4% ascorbic acid and their combinations, then stored at 1...
The aim of the present study was to investigate the effects of SA on UV-A, UV-B, and UV-C stressed plants. Data showed that SA counteracted the UV harmful effects on pepper. Pepper (Capsicum annuum L.) seedlings sprayed with salicylic acid (SA) and treated with UV-A (320-390 nm), UV-B (312 nm), and UV-C (254 nm) of 6.1, 5.8, and 5.7 W m-2, respectively. UV significantly increased contents of as...
This study was conducted to evaluate drought resistance of milk thistle (Silybum marianum L.) at seedling stage. The experiment was designed as a split plot in a randomized complete block design. Treatments were combination of drought stress levels as main plots and different milk thistle ecotypes as subplot layouts replicated 3 times and run in a hydroponic system. Root length, root volume, ch...
