Increasing the altitude causes extensive changes in the environmental conditions. Three species of Quercus brantii Lindl., Pistacia atlantica Desf. and Crataegus pontica C. Koch. are the dominant species in the forests of Ilam province. The sampling was done from Qalajeh Mountain at the altitude from 1300-2000 m a.s.l. The effect of altitude on photosynthesis, photosynthetic pigments and some b...
The soybean vegetative storage protein genes vspA and vspB are highly expressed in developing leaves, stems, flowers, and pods as compared with roots, seeds, and mature leaves and stems. In this paper, we report that physiological levels of methyl jasmonate (MeJA) and soluble sugars synergistically stimulate accumulation of vsp mRNAs. Treatment of excised mature soybean (Glycine max Merr. cv Wi...
(14)C-Sugar uptake and incorporation into starch by slices of developing maize (Zea mays L.) endosperm were examined and compared with sugar uptake by maize endosperm-derived suspension cultures. Rates of sucrose, fructose, and d- and l-glucose uptake by slices were similar, whereas uptake rates for these sugars differed greatly in suspension cultures. Concentration dependence of sucrose, fruct...
Water deficit can be considered as one of the most important abiotic factors limiting plant function, which has also adverse affects on growth and production of medicinal plants. In this research, in order to evaluate the effects of water deficit stress on of Artemisia dracunculus plant, a completely randomized design with three replications was performed in greenhouse conditions. The ex...
Changes of the main sugars and organic acids content in Asian pear (Pyrus serotina Rehd.) Cultivars ‘KS’9 and ‘KS’13 grown in Tehran were studied from fruit set to maturity. The main sugars and organic acids content in fruits were determined 1 and 2 months before harvest, at the time of harvest and 1, 2 months after harvest time using High Performance Liquid Chromatography (HPLC). Fruits were s...
Caesalpinia echinata seeds stored in laboratory environmental conditions lose their viability in one month whilst under low temperatures germination is maintained for 18 months of storage. These seeds are tolerant to desiccation, keeping their viability up to 0.08 gH2O.gDW-1. Since soluble carbohydrates are believed to be involved with desiccation tolerance and seed storability, the aim of this...
The relationships between rooting potential with endogenous phenolic compounds, nitrogen and soluble carbohydrates of cuttings for five olive cultivars (‘Rowghani’, ‘Dusti’, ‘Tokhmekabki’, ‘Konservalia’ and ‘Amigdalolia’) were investigated. Extracts of the leaves and the base of the cuttings were used for analysis of biochemical compounds. Results showed that there were significant differences ...
Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicate...
