Environmental stress, especially drought stress, can play an important role in the reduction of the plant growth stage, specifically duringgermination in arid and semi arid regions in Iran.. In order to study the effects of drought stress on germination indices in wheat cultivars, an experiment was conducted in factorial form, using a completely randomized design of four replications. In this e...

in recent years most activities of rice research institute, has been focused on introduction of high yielding as well as high quality rice cultivars. in 1994, 185 lines introduced from international rice research institute (irri) to rice research institute of iran (rrii), were evaluated in observational and statistical experiments in rrii for two years, and eight lines were selected. these line...

introduction of high yielding as well as high quality rice cultivars is one of the most important activities at rice research institute of iran (rrii). in 1991, 210 rice lines introduced from international rice research institute (irri) to rice research institute of iran were evaluated in observational and statistical experiments in mazandaran for two years, and seven lines were selected. these...

intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...

SDS-PAGE electrophoresis was used to study the effect of NaCl on protein expression in two cultivars of tomato (Solanum lycopersicum L.): Edkawi (salt-tolerant) and Castle rock (salt-sensitive). Five-day-old seedlings were grown on MS agar media supplemented with 0, 50, 100, 150, 200 and 300 mM NaCl. Two days after treatment the seedlings were examined to determine the effect of salt on their g...

Drought stress is the main abiotic factor affecting rice production. Rain-fed upland rice which is grown on unbounded fields and totally dependent on rainfall for moisture is more prone to drought stress compared to rice from other ecosystems. However, upland rice has adapted to this limited water condition, thus are more drought tolerant than rice from other ecosystems. We performed the first ...

line g11867 was first introduced in iran together with 206 other white, chitti and red beans lines through ciat, and was tested in different breeding experiments from 1992 to 1999. it was selected as a superior line in all experiments. in 2001 this line was evaluated with other six lines for drought tolerance, and it was found to be more tolerant than cv. daneshkadeh the check cultivar. line g1...
