This study investigates the applicability of empirical and radiative transfer models to estimate water content at leaf and landscape level. Themain goal is to evaluate and compare the accuracy of these two approaches for estimating leaf water content by means of laboratory reflectance/transmittance measurements and for mapping leaf and canopy water content by using airborne Multispectral Infrar...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
Selenium has a protective and positive effect on the quantitative and qualitative characteristics of the plants. In order to investigate the effect of selenium foliar application on leaf proline content and some quantitative and qualitative characteristics of rapeseed cultivars under end-season thermal stress, a factorial split plot experiment was conducted in a randomized complete block d...
To determine the effects of salinity and boron excess in irrigation water on relative growth rate (RGR), net assimilation rate on a leaf weight basis (NAR), and leaf weight ratio (LWR) of pistachio, three pistachio rootstocks (Badami -Zarand, Sarakhs and Ghazvini) were used. Rootstocks were grown in soil in eight-liter polyethylene pots. Sodium chloride treatments were 0, 75,150 and 225 mM NaCl...
The pollution caused by the presence of heavy metals in the air, water and soil is one of the world's ecological problems. In this study, the effect of different concentrations of calcium on the absorption and accumulation of Cd and Zn in M. flavida from Brassicacea was studied. For this purpose, concentrations of 100, 400 and 1600 µM calcium and 1, 5 and 10 µM Cd and 10, 20 and 40 ...
To evaluate the effect of ascorbate and gibberellin on some morphological traits and relative water content of medicinal plant fenugreek in different levels of salinity, an experiment was carried out in Shahr- e - Rey branch of Islamic Azad University in October 2012. The experiment was arranged as factorial experiment in the basis of completely randomized design with four replications. The exp...

Low quality of irrigation water along with increasing salinity level has reduced the olive yield over recent years in Iran. Screening of salinity tolerance in olive cultivars using gas-exchange parameters, water use efficiency, and relative leaf chlorophyll content are important in olive development programs. This study was carried out to assess the salinity tolerance of four olive cultivars (A...
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...
Water resources are limited. Thus, one of the ways to prevent the decline of maize yield under water shortage conditions is the use of growth regulators. In this study, the effects of proline (150 mg/L) and salicylic acid (0.5 mmol) on the yield and water use efficiency of maize were investigated under three irrigation regimes, including complete irrigation (control), 75% of complete irrigatio...
