Morphological and molecular study on some species of Phoma and related taxa in Iran
The genus Phoma Sacc. consists of important fungal plant pathogenic species occurring on economically important cultivated crops in spite of many other saprobic species. Thus, the aim of this study was to identify 35 isolates of Phoma species and related taxa collected from different hosts by means of morphological and molecular characters. Multi-locus phylogenetic analyses based on ITS1-5.8S-I...
متن کاملAnatomical structure of cladodes of Ruscus L. taxa (Liliaceae) in Turkey
Microscopical properties of transverse sections from the cladodes of each taxa were illustrated and photographed. In the cross section, it was not possible to differentiated upper and lower epiderma of cladodes. In the mesophyll of cladodes palisade and spongy parenchyma are not seen. There are a few layers of parenchyma cells beneath the upper epidermis and above the lower epidermis. Cross sec...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولEffect of hydropriming on morphological and physiological performance of aged groundnut (Arachis hypogaea L.) seeds
Low viability and poor vigour due to seed deterioration are major problems for successful agricultural production. In this experiment, the ability of hydropriming to ameliorate seed deterioration damage was studied in groundnut. Groundnut seeds were subjected to accelerated ageing for 96 hours at 40 °C and then hydroprimed at 25 °C for 6, 12 and 18 hours. Regardless of duration, hydropriming si...
متن کاملAssessment of the antioxidant potential and fatty acid composition of four Centaurea L. taxa from Turkey.
This paper focused on the assessment of antioxidant property and fatty acid composition of four Centaurea species. The antioxidant activity of its methanol extract was evaluated by several in vitro experiments including phosphomolybedum assay, DPPH assay, β-carotene/linoleic acid, ferric and cupric reducing power. Total phenolic and flavonoid contents were also evaluated. The methanol extract o...
