seed protein usually is not sensitive to environmental fluctuations; its banding pattern is very stable which advocated for cultivars identification purpose in crop. this study was planned to study effect of water deficit on protein content and protein banding pattern of wheat genotypes. in this study five wheat genotypes were planted in early november, growing season of 2008-2009. the experime...

Sampling of the Fourier transforms of fingerprints is studied with neural networks to detect regions useful for their classification. Ring-wedge detector (RWD) is modified and simulated to sample such regions. The output of the detector is propagated through a three-layer feedforward-backpropagation neural network for checking the classification performance. Modified detector's performance is a...

canopy temperature (ct) is used as a selection tool to improve crop adaptation to drought. the aim of this work was to investigate association of some photosynthetic characters with ct during grain filling in three cereal species. for this objective, a two-year study (2009-2011) was carried out in kurdistan province in western iran. four genotypes of triticale, three cultivars of bread wheat, 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...

the objective of deficit irrigation is to increase water use efficiency by reducing of water quantity or wave off further irrigations that have not necessary. cotton plant is sensitive to irrigation timing and quantity through different growth stages. the field trail was conducted at hashemabad cotton research station (gorgan) to determine water consumption and cotton sensitivity to deficit irr...

one of the soil and water management practices in order to delay drought stress under water deficit condition; is superabsorbent application. in order to study the effect of  superabsorbent application on yield and yield components, two antioxidant enzymes activity and water relation of two canola hybrids under terminal drought stress condition, a research was carried out in ahvaz climate condi...

We tested, compared and modified three models of stomatal conductance at the leaf level in a forest ecosystem where drought stress is a major factor controlling forest productivity. The models were tested against 2 years (1999 and 2000) of leaf-level measurements on ponderosa pine (Pinus ponderosa Dougl. ex Laws.) growing in the Mediterranean climate of California, USA. The Ball, Woodrow and Be...
