To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...

drought and salinity are the most important limiting factors of plant growth and development in many regions of the world. in this regard, using of species that are able to have higher production in this condition is a suitable strategy. in order to study the effect of drought and salinity stresses on morphophysiological properties of kallar grass (leptochloa fusca l. kunth), a factorial experi...

trr14 is a novel protein important in trehalose (α-d-glucosyl-[1,1]-α-d-glucopyranoside) signaling in arabidopsis. in this research, we provided evidences to demonstrate that trr14 plays role in arabidopsis responses to salt and drought stress. the transgenic arabidopsis plants over-expressing trr14 under the control of camv 35s promoter were generated. transformed lines showed higher transcrip...

Drought stress is a serious adverse factor limiting growth and productivity of sunflower. Evaluation of defense systems is important for producing resistant cultivars. In this study, some agro-morphological and molecular characteristics of six sunflower lines were evaluated under normal and irrigation at 40 and 60% of field capacity in randomized complete block design (RCBD). The results showed...

water deficit is one of the most common constraints to crop productivity in the world and iran. in order to study effect of drought stress on morphologic traits, yield and yield components of 34 hybrids of corn, an experiment was carried out based of complete randomized block design with three replication under f.c. irrigation and drought stress in khorasan razavi agricultural research and natu...
