30 milled rice samples were collected from retailers in four states of malaysia. these samples were evaluated for eurotium spp. contaminations by direct plating on malt extract salt agar (mesa). all eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (its1) and its2 of the rdna. four eurotium species (e. rubrum, e. amstelodami, e. ...
In medicinal plants, secondary metabolites are very important and factors influencing their quantity and quality are considered. Iranian borage (Echium amoenum Fisch. & C. A. Mey.) belonging to Boraginaceae family is a long-day, biennial, herbaceous plant, with a lot of rough trichomes, is found in northern Iran. In the present work, effects of silicon on some morphological, anatomical and ph...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
The purpose of this experiment, evaluating hetrotoxicity potential of aqueous extract of various organs of medicinal plant of Malva sylvestrisa L. on morphological, physiological characteristics and biochemical of total phenols of Cichorium intybus L. and Echinochloa crus-galli L. under hydroponic culture as two separated experiments in completely randomized design in botanical laboratory of Go...
We conducted this study during the Summer, 2013 to evaluate morphological features of the species of the genus Paracobitis in Sistan basin. For this purpose, 60 specimens randomly were caught by a gill-net from different parts of Lake Chah Nime (Zabol, Sistan and Baluchistan), fixed in formalin solution and transferred to a laboratory for further examination. We measured 37 absolute morphologic...
Chromium-VI would impose detrimental effects morphological, physiological, and metabolic in plants. This study aimed to research the impact of citric acid (0, 2.5 and 5 mM), on different the morphological and physiological characteristics of garden cress exposed to chromium-VI stress (0, 1, and 10 mM). Results showed that some growth parameters, chlorophyll, carotenoids, and DPPH activity decre...
pot experiment was carried out to investigate the effects of ethylenediaminetetraacetic acid (edta) on some morphological characteristics of thlaspi caerulescens l., and also on the accumulation of lead (pb) and zinc (zn) in roots and shoots of t. caerulescens l.. experiments were then set up in three treated pots with doses of 3, 6 and 9 mmol kg-1 of edta and control pots (c: uncontaminated so...
in order to investigate the morphological reactions of cutting of damask rose to iba (indole butyric acid) in different times, an experiment was done in a factorial experiment based on rcd and three times with three replications and 10 observations per each replication. in this experiment, the simple effects of iba, time and their interaction effects were measured against morphological properti...
the purpose of this quantitative study was to investigate the relation between efl teachers’ self-efficacy beliefs and their success. moreover, the study was an analysis of the teacher age, gender and years of teaching experience, to examine the manner in which these factors relate to teacher self-efficacy as defined by bandura (1997) and teaching effectiveness as evaluated by their own student...
