A laboratory research carried out to evaluate the effect of drought stress on germination characteristics in two 'Indian' and 'Isfahanian' populations of Fenugreek. This experiment performed in a factorial experiment based on a completely randomized design with three replicates. Four levels of drought stress applied by using polyethylene glycol 6000. Percentage of germination, germination rate,...

Response of six sunflower hybrids/ breeding lines viz., G-101, SF-187, Hysun-33, Hysun-38, 64A-93 and S-278 to drought stress imposed at germination and seedling growth stages was investigated in a laboratory experiment (25±3C). Five water stress levels of zero (control), -0.35, -0.6, -1.33, and 1.62 MPa were developed using polyethyleneglycol-6000 (PEG-6000). Complete randomized design with th...

  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 ...

In order to study of agronomic, physiological characteristics, drought tolerance and to identify  Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...

Use of physiological parameters as fast tools to screen for drought tolerance in sugarcane: Drought is one of the major limitations to plant productivity worldwide. Identifying suitable screening tools and quantifiable traits would facilitate the crop improvement process for drought tolerance. In the present study, we evaluated the ability of four relatively physiological parameters (variable-t...

In order to study the drought stress in soybean (Glycin max L.), experiments with two stages and 25 soybean genotypes based on Simple Lattice Design 5×5 with two replications in two locations (normal and drought condition) were carried out in Bojnourd. Also evaluation of germination traits with three replications based on Completely Randomized Design has performed. Drought stress was applied in...

drought stress is a major factor limiting crop production. investigation of physiological characteristics related to drought tolerance and crop production may be useful in selecting drought tolerant cultivars as well as in improving crop yield. two drought tolerant (azar2 & back cross roshan) and two drought susceptible (marvdast & shiraz) cultivars were investigated in both greenhouse and fiel...

Drought is a threaded factor in the world production and application of breeding methods could improve the tolerant and adapted cultivators under drought stress condition. In order to evaluate and determine the stress tolerance indices and identifion of tolerant genotypes to drought stress, 15 safflower genotypes were evaluated in a randomized complete block design with three replications in tw...

Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...
