The remote sensing ecological index (RSEI) has been widely used in the rapid monitoring and evaluation of regional environment; however, research on main factors that cause changes RSEI impact human activities mining area is not often explored. To this end, paper selected Landsat (TM/OLI) series images from 1986 to 2022; extracted four important indicators normalized difference vegetation (NDVI...

Drought stress is an important limiting factor for plant growth.  Using selection indices, it is possible to identify cultivars with high yield in normal and stressed conditions.  So, the genetic analysis of drought tolerance indices can play important role in plant breeding programs. In order to identify molecular markers linked with drought tolerance indices in sunflower, 72 recombinant inbre...

Drought is a complex phenomenon caused by the breaking of water balance and it has always an impact on agricultural, ecological and socio-economic spheres. Although the drought indices deriving from remote sensing data have been used to monitor meteorological or agricultural drought, there are no indices that can suitably reflect the comprehensive information of drought from meteorological to a...

  This study was conducted at Research Farm of Isfahan University of Technology to evaluate drought tolerance potential of 23 F2:4 wheat lines derived from the cross of Virmarin (susceptible line) and Sardari (tolerant line). A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3 and 120±3 mm evaporation from class A pan for ...
