The chloroform extract of the stem bark of Amburana cearensis was chemically characterized and tested for antibacterial activity.The extract was analyzed by gas chromatography and mass spectrometry. The main compounds identified were 4-methoxy-3-methylphenol (76.7%), triciclene (3.9%), α -pinene (1.0%), β -pinene (2.2%), and 4-hydroxybenzoic acid (3.1%). Preliminary antibacterial tests were car...
In order to evaluate the foliar application of sodium nitroprusside on some morphological and biochemical properties of Alstroemeria cultivar Orange Queen, a research was conducted in a completely randomized design with 3 replications under hydroponic cultivation in the research greenhouse of Urmia University. Sodium nitroprusside was sprayed at concentrations of 0, 50, 100 and 200 μM. At the e...
ABSTRACT: This study aimed to morphologically characterize the isolates of Ceratocystis fimbriata from yerba mate and evaluate effect culture medium temperature on mycelial growth sporulation C. fimbriata. For morphological characterization 11 monosporic fungus, slides were prepared determine dimensions sexual asexual structures fungus. Four experiments conducted in different mediums temperatur...
The article discusses the dynamics of changes in area assimilation surface organs different genotypes durum and soft wheat as a result drought, differing ripening period. As you know, under drought conditions, water potential soil first decreases, then plants; at later stages, turgor pressure stomata close there is sharp decrease photosynthetic activity. This situation creates stress organisms ...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
BACKGROUND A Chenopodium album L. biotype surviving in atrazine-treated Serbian corn fields (VC) was compared against atrazine-susceptible (S) and atrazine-resistant (R) standards. RESULTS Atrazine (2 kg ha(-1)) killed S and VC shoot biomass 15 days after treatment (DAT), but R was only suppressed by 42% and survived 8 kg ha(-1). Atrazine at 2 kg ha(-1) only inhibited VC height by 60% as agai...
