effect of seed priming by salicylic acid and application of controlled water stress in flowering stage on some physiological characters such as relative water content, chlorophyll index, photosynthetic rates, transpiration rates, stomatal conductance, and leaf internal co2 concentration was investigated on cowpea (vigna unguiculata l. cv. parastoo) plants. experiment was done as a split block d...

A combined model to simulate CO₂ and H₂O gas exchange at the leaf scale was parameterized using data obtained from in situ leaf-scale observations of diurnal and seasonal changes in CO₂ and H₂O gas exchange. The Farquhar et al.-type model of photosynthesis was parameterized by using the Bayesian approach and the Ball et al.-type stomatal conductance model was optimized using the linear least-sq...

Stable carbon isotope discrimination (delta13C), photosynthetic performance (A), dry matter accumulation (DW), and sucrose yield (Y(s)) of sugar beet were evaluated in a glasshouse experiment under transient (TS) and permanent (PS) water stress. A was significantly reduced under drought, to an extent depending on stress duration. The reduced A was strictly associated with a low DW and Y(s), the...

this experiment was conducted to evaluate the effects of different levels of costmary(tanacetum balsamita)medicinal plant on performance, egg traits, and blood biochemical parameters of laying hens. hundred-eighty of hi-line laying hens (w 36) from 46 until 58 weeks of age were used in a completely randomized design in five treatments and three replicates (12 birds per replicate). the treatment...

This study aims at determining the personality traits and investment patterns in the stock market and presenting the pattern with a behavioral finance approach. This is an applied, descriptive- survey, and cross-sectional study. The statistical population includes real investors in the Tehran Stock Exchange. The required information was collected using questionnaire and was analyzed using SPSS ...

Improving photosynthesis to raise wheat yield potential has emerged as a major target for wheat physiologists. Photosynthesis-related traits, such as nitrogen per unit leaf area (Narea) and leaf dry mass per area (LMA), require laborious, destructive, laboratory-based methods, while physiological traits underpinning photosynthetic capacity, such as maximum Rubisco activity normalized to 25 °C (...
