ماسه در مطالعة فرسایش آبی و بادی، جایگاه انکارناپذیری دارد و بررسی کیفی و کمّی آن در شناخت فرآیندهای غالب فرسایشی و کنترل آن نقش بسزایی دارد. در این تحقیق به بررسی کمّی و کیفی ذرّات ماسه به روش مقایسة تحلیلی بین دو منطقة ساحلی و مناطق داخلی پرداخته شده است. جهت دستیابی به این هدف، دو محدودة مطالعاتی در جاسک و جنوب غرب ریگ مرنجاب، برگزیده و پژوهش در آنها آغاز شد. در این پژوهش، نخست از تصاویر ماهو...
34 Characterizing traits critical for adaptation to a given environment is an 35 important first step in understanding how phenotypes evolve. How animals adapt 36 to the extreme heat and aridity commonplace to deserts represents is an 37 exceptionally interesting example of these processes, and has been the focus 38 of study for decades. In contrast to those studies, where experiments are 39 co...
Micrococcus luteus strain K39 is an endophyte bacterium isolated from roots of the desert plant Cyperus conglomeratus collected from the Red Sea shore, Thuwal, Saudi Arabia. The draft genome sequence of strain K39 revealed a number of enzymes involved in salinity and oxidative stress tolerance or having herbicide-resistance activity.
Antibacterial properties of hexane, chloroform and aqueous extracts of roots of Acorus calamus, Aristolochia indica, Cyperus rotundus, Desmodium gangeticum, Holostemma ada- kodien and Kaempferia galanga, used in the traditional medicine were studied on Bacillus pumilis and Eschericia coli by disc diffusion method.
Halomonas elongata strain K4 is an endophytic bacterial strain that was isolated from roots of Cyperus conglomeratus collected at the Red Sea coast in Thuwal, Saudi Arabia. Here, we present a draft genome sequence of this strain, highlighting a number of pathways involved in plant growth promotion under salt stress.
Cyperus articulatus is an insect repellant plant commonly found in Northern Nigeria and used traditionally in pest control. The light petroleum and methanol extracts of the plant's rhizome were evaluated against Tribolium casteneum Hbst (the red flour beetle) using standard techniques. The methanol extract showed more antifeedant property than the light petroleum extract, while both the extract...
Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...
