The new coronavirus origin is one of the important controversial subjects in the study of this virus. There are many contradictions about the epidemiological data and bat origin of the virus. In this regard heterodox view by cosmic biology concepts, exceptionally bright fireball event a few months before the outbreak in China, and extraordinary weak solar cycle with many sunspot free days could...
Different explants of Crocus sativus L. such as corm, style, ovary, petal, anther and leaf were cultured on LS and MS media supplemented with NAA and BAP or 2,4-D plus BAP at different combinations. Shoot and corm induction occurred in addition to the formation of other organs. Efficient plantlet regeneration with strong roots occurred at 1 mg 1-I of both NAA and BAP. An increase in 2,4-D l...
Field experiment was conducted at Akwa Ibom State University teaching and research farm during the 2020 2021 cropping seasons to evaluate growth yield of cocoyam on varying rates organic manure in a based-intercropping system Obio Akpa, Nigeria. Experiment laid out randomized complete block design with three replications. Treatments were four – PM 0 t/ha, 2.5 5.0 7.5 t/ha) crop mixtures - Sole ...
introduction saffron is one of the most economically important plants across iran and all over the world. the most important cultivated areas of saffron are in khorasan-e razavi and southern khorasan provinces (jihad keshavarzi khorasan razavi, 2013). the corm is the reservoir of photosynthetic materials and plays an important role in the saffron life cycle. corm size and physicochemical charac...
guaiacol peroxidases (gp) are haem-containing enzymes participating in many physiological processes in plants. the expression pattern of these enzymes is organ-specific and developmentally regulated. methods: the presence of gp activity in extract samples, prepared from crocus sativus l. corms that were either dormant or rooting for 3, 6 and 10 days, was investigated. results: kinetic studies r...
Iran with a cultivation area of 45000 ha and production of 150 ton/year is the number one saffron producer in the world. Planting of large size corms will increase flowering, but production of corms (number and size) may be affected by irrigation method or frequency. In this research which is performed in the farm of College of Agriculture, Shiraz University, the effects of method and frequency...
