The water stress treatments including 100, 75, 50 and 25 Percent of field capacity (FC) were applied. The results showed that water deficit stress significantly (p<0.01) decreased plant height, canopy cover volume, canopy cover surface, shoot dry weight and root dry weigh, root thickness as well as soluble sugars content. Also, proline, chlorophyll content and root length significantly increased under drought stress. The maximum amount of proline, a, b and total chlorophyll and root length was observed in 25% of field capacity. Maximum plant height, crown volume and leaf area was obtained at 75% of field capacity. The shoots and roots dry weight of and crown area was observed in plant treated at 100% of field capacity.

Accordingly, three-year old Persian maple seedlings were submitted based on completely randomized design to four different acid rain regimes: pH 3, 4, 5 and near neutral (pH 6) as control, in tree replications, during 10 days. At the end of experiment, some visible changes such as necrotic spots and leaf marginal wrinkle were observed in the plant leaves sprayed only with AR of pH 3.

However, reducing of AR had no effect on leaf chlorophyll content by pH 4.0, whereas AR of pH 3.0 dramatically degraded it. In addition, AR did not significantly affect superoxide dismutase (SOD) activity. On the contrary, it enhanced peroxidase (POD) and ascorbate peroxidase (APX) activities by pH 4.0, but AR of pH 3.0 markedly decreased them, thereby, the antioxidative system was weakened and injury appeared.

Experimental treatments included three planting dates (April 9, May 9 and June 8 2013) and three planting density (7, 10 and 16 plant/m2). Measurements were performed in full bloom stage. Results of experiment showed a significant increment of penetration depth of root in 9 may with a density of 16 plant/m2. The highest root volume and dry matter were related to 8 June and 7 plant/m2.

Plants grown on 8 June with a density of 7 plant/m2 resulted to the highest ratio of dry matter root to total and root to shoot.

Growth parameters, the contents of carbohydrates, pigments and the activity of some antioxidant enzymes were compared between wild type and ntrc mutant lines during dark induced senescence. Darkness led to decreased fresh and dry weights, chlorophylls and carotenoides, starch and protein contents in both wild type and mutant plants and there were no significant differences in the interactions of genotypes and treatments regarding to theses parameters. Darkness also induced the accumulation of anthocyanins, total and non-reducing sugars however, the accumulation of the carbohydrates in mutant lines was more pronounciated than wild type plants and again there were no significant differences in response of wild type and mutants to dark treatment. The activities of catalase, peroxidase and polyphenol oxidase of mutant lines were significantly greater than wild type plants. While darkness decreased the activities of ascorbate peroxidase and catalase it led to increased activities of peroxidase and polyphenol oxidase especially in the mutant lines.

Dry matter partitioning of leaf: stem in broiler litter treatments (60.3:39.7) was more balanced than cattle manure treatments (63.6:36.4). Nitrate amount of BL and CM treatments was significant lower than the chemical fertilizer treatments. In general, it can be concluded that purslane photosynthesis and production is more affected by broiler litter application than the chemical fertilizer and cattle manure, which that it causes a considerable increase in crop production and health.}, Keywords = {Chlorophyll, carotenoids, nitrogen, phosphorus}, volume = {5}, Number = {15}, pages = {181-194}, publisher = {Iranian Society of Plant Physiology}, url = {http://jispp.iut.ac.ir/article-1-379-en.html}, eprint = {http://jispp.iut.ac.ir/article-1-379-en.pdf}, journal = {Journal of Plant Process and Function}, issn = {2322-2727}, eissn = {2383-3688}, year = {2016} } @article{ author = {Shahbazi, Taiebe and Saiedi, Mohsen and Nosratti, Iraj and alaliHonarmand, Saied J}, title = {Evaluation the Effect of airborne dust on physiological characteristics and yield of different wheat varieties (Triticum sp.)}, abstract ={To evaluate the effect of airborne dust on some physiological characteristics and yield of different wheat varieties, a field experiment was conducted at Research Farm of Razi University, Kermanshah, Iran in 2013. The evaluated treatments were washing and un-washing shoots of various wheat varieties including Pishgam, Zarin and Behrang. Measured traits were as relative water content (RWC), SPAD, chlorophyll content (Chl), soluble protein of flag leaf (SP), stomatal conductance (SC), leaf temperature (LT) and chlorophyll fluorescence (Fv/Fn). Results of this study showed that washing wheat shots aimed at removing dust particles had significant effect on grain yield and grain number per spike, leaf area index, leaf soluble protein, SPAD, stomatal conductance and leaf temperature. The results of the counting of number of seed position per spikelet and grain weight per spikelet showed that washing enhance the quality of both traits. In general, under dusty conditions, Phishgam cultivar had the highest grain yield.}, Keywords = {Chlorophyll fluorescence, photosynthesis, spikelet, washing shoot}, volume = {5}, Number = {15}, pages = {195-204}, publisher = {Iranian Society of Plant Physiology}, url = {http://jispp.iut.ac.ir/article-1-294-en.html}, eprint = {http://jispp.iut.ac.ir/article-1-294-en.pdf}, journal = {Journal of Plant Process and Function}, issn = {2322-2727}, eissn = {2383-3688}, year = {2016} }
