The study was conducted to appraise the effect of saline stress on growth, gas exchange, chlorophyll fluorescence, mineral nutrients and non-enzymatic antioxidants in 2 mungbean [Vigna radiata (L.) Wilczek] lines (97001 and 97012). Seeds of each line were sown in sand-filled pots. When the plants were 30 day-old, 2 saline regimes [control (non-saline – full strength Hoagland’s nutrient solution...

this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...

The essential oils obtained by hydrodistillation from the stem, leaf and flower of Phlomis aucheri Boiss., which is endemic to Iran, stem, leaf and root of Teucrium polium L. and solvent free microwave extraction oil from leaf of Ajuga chamaecistus Ging. subsp. chamaecistus were analyzed by GC and GC/MS. Germacrene D (11.1%, 28.3% and 21.1%) was the main constituent in the stem, leaf and flower...

Knowledge of the location and magnitude of the resistance to water flow in a plant is fundamental for describing whole plant response to water stress. The reported magnitudes of these resistances vary widely, principally because of the difficulty of measuring water potential within the plant. A number of interrelated experiments are described in which the water potential of a covered, nontransp...

Global vegetation models use conceived relationships between functional traits to simulate ecosystem responses to environmental change. In this context, the concept of the leaf economics spectrum (LES) suggests coordinated leaf trait variation, and separates species which invest resources into short-lived leaves with a high expected energy return rate from species with longer-lived leaves and s...

in order to evaluate the inter-specific hybrid p. atlantica × p. vera cv. ‘badami- riz- zarand’ to drought stress, a factorial experiement was conducted as based on a completely randomized design of three irrigation intervals 3, 6 and 9 days on qazvini, badami-riz-zarand and the hybrid of p. atlantica × p. vera cv. badami- riz-zarand rootstocks of pistachio. results indicated that such physiolo...
