Selenium has a protective and positive effect on the quantitative and qualitative characteristics of the plants. In order to investigate the effect of selenium foliar application on leaf proline content and some quantitative and qualitative characteristics of rapeseed cultivars under end-season thermal stress, a factorial split plot experiment was conducted in a randomized complete block d...
in order to evaluate effects of iron, zinc and manganese, and the methods of applying them on yield and yield components of sweet corn (zea mays saccharata), an experiment was performed as factorial based on randomized complete block design with four replications at the research farm of urmia university. experimental factors were micronutrient fertilizers with four levels (control, iron, zinc a...
Alternative splicing plays a crucial role in plant development as well as stress responses. Although alternative splicing has been studied during development and in response to stress, the interplay between these two factors remains an open question. To assess the effects of drought stress on developmentally regulated splicing in maize (Zea mays), 94 RNA-seq libraries from ear, tassel, and leaf...
The structure and leaf development of the shoot apical meristem in embryos and seedlings of Thuja orientalis L.were observed by using SEM,and the area of the shoot apical meristem was studied by an image analyzer.The shoot apex of embryos was of a round tip cone shape with flat sides;it was transformed into an inverted boat shape.In seedlings,the shoot apical meristem was of a convex-rectangula...
In this research, effect of drought stress on leaf characteristics was investigated in the experimental field of Miandoab Azad University, Iran using four facultative barley cultivars. Two separate experiments were conducted in pot and field conditions. In both experiments a factorial arrangement was used and the treatments were completely randomized in four replications. In each experiment ha...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...

Oil seed rape (Brasica napus) is an important crop, which is cultivated in Iran for oil production. As a management practice deficit irrigation strategy is applied to cope with water shortages, especially during drought periods. This research was conducted to study the effect of water stress on physiological parameter of oil seed rape in the experimental research field of Collage of Agriculture...
Class 1 KNOTTED1-LIKE HOMEOBOX (KNOXI) genes encode transcription factors that are expressed in the shoot apical meristem (SAM) and are essential for SAM maintenance. In some species with compound leaves, including tomato (Solanum lycopersicum), KNOXI genes are also expressed during leaf development and affect leaf morphology. To dissect the role of KNOXI proteins in leaf patterning, we express...
Environ.Entomol.21(2):264-268(1992) ABSTRACT Soybean, Glycine max (L.) Merr., resistance to insects has been shown to vary with planting date and leaf age. This study determined effects soybean genotype, planting date, and leaf age had on feeding behavior of com earworm, Helicoverpa zea (Boddie). Soybean genotypes 'Cobb' (susceptible) and 'GatIR81-296' (resistant) were planted early (29May) and...
