This experiment was conducted to evaluate drought tolerance of different safflower genotypes as a split- plot experiment based on a complete block design with three replications. The main plot was irrigation at three levels on the basis of 70, 120 and 170 mm cumulative evaporation from Class A pan and ten different genotypes of the safflower were considered as subplots. Results of analysis of v...
به منظوربررسی صفات مورفولوژیک، فیزیولوژیک و شناساییqtlهای مرتبط با تحمل به خشکی، 75 لاین اینبرد نوترکیب حاصل از تلاقی روشن و سوپرهد استفاد گردید.آزمایش مزرعه ای در شرایط نرمال و کمبود آب در سال زراعی 1391-1390 در قالب طرح بلوک های کامل تصادفی با دو تکرار در مزرعه تحقیقاتی دانشگاه شهید باهنر کرمان اجراگردید. تجزیه واریانس در شرایط تنش نشان داد که اختلاف معنی داری برای همه صفات بجز تعداد گره بین ...
Drought as one of the most important environmental stresses causes serious threats in amount and efficiency of crop productions. To evaluate drought resistance by using drought tolerance indices in safflower varieties, a research was conducted at the Research Farm of Bu-Ali Sina University. Experiment was planed as split-plot on the basis of randomized complete block design with three replicati...
drought stress, especially drought at terminal stages, plays an important role in reduction of yield in field crops such as common beans. 50 genotypes of common bean including 3 control genotypes (dehghan, bahman and naz) were used to evaluate and identify the tolerant genotypes. this experiment were performed in a randomized complete block design (rcbd) with three replications under two condit...
using medicinal plants as drug or spice in food have significantly increased in recent decades. also, production of this plants restricted by drought stress. therefor the aim of this was investigation of drought stress effect on fruit and essential oil yield of different endemic coriander genotypes. in this regard, 14 coriander genotypes subjected to two levels of water treatments in two separa...
The aim of this research was to determine the effective drought indices such as NDVI, VCI, EVI, TVX, VTCI, VHI, TCI and NVSWI based on some criteria. The satellite-based drought indices have different data from vegetation and temperature conditions. Linear and trend analysis showed that satellite-based drought indices based on vegetation condition were not more efficient indices such as NDVI an...
Basically, the most important limiting factor in plant growth is the lack of water. More lands in Iran are located in arid and semi-arid region and so identifying of ghenotype that can produce acceptable yield under drought conditions is essential. In order to identification of drought stress tolerant varieties, 20 wheat cultivars were evaluated at three stress levels (control, -0.6 and -1.2 MP...
In this study, different genotypes of faba bean were evaluated for Tolerance index and biochemical compounds under drought stress. 21 Genotypes of faba bean were studied based on RCBD design with three replications in two irrigation treatments (including normal irrigation and drought stress) during two cropping years (2018-2019) at Gorgan Agricultural Research Station. Based on the potential (Y...
Physiological basis of genetic variability in drought response and its association with yieldand related indices is not clear in Brassica. In this study 36 accessions belonged to sevenspecies of Brassica were evaluated under normal, moderate and severe stress environments.Physiological traits along with seed yield, seed yield components, oil content and two selectionindices (stress tolerance in...
