the total nitrogen content of three barley cultivars: cehada capa (resistant at 25ac), cl 1243 (resistant at 5°c) and rika 1 (susceptible at all temperatures) to puccinia hordei was determined and compared in healthy and infected plants at 5° and 26°c. the results indicate that the total nitrogen content of cv. cehada capa leaves was greater than that of cl 1243 and rika 1 and that of cl 12...
until now many studies have been done over recent decades throughout the world to show the right age to start english. in iran, research is still at an early stage in terms of evaluating teachers’ beliefs about teaching children english. the problem of at what age to start teaching english and how to teach english to elementary school children has not been solved neither in this country nor els...
Silicon (Si) is a beneficial element for on plant growth and development that plays an important role in plant resistance to environmental stresses such as salinity and drought. The present research was conducted to study the effect of Si and water deficit on biochemical, physio-morphological and qualitative traits of cut rose cv. Club-Nika under greenhouse conditions. The factorial experimen...
Guar (Cyamopsis tetragonoloba L.) is a tropical drought tolerant crop, potentially proper for arid areas. The objective of present survey was to evaluate the effect of different irrigation regimes and salicylic acid levels on morphological, physiological and seed yield of Guar. The present experiment was conducted as split plots based on randomized complete blocks design with four replications....
in this study, eleven cultivars of apricot including two early ripening (noori pishras and pishras tabasi) varieties, four mid ripening cultivars namely (shahroudi, lasjrdy, ghazi gahani and bagheri) and five late ripening cultivars i.e. (shahroudi51, shahroudi48, shahroudi29, shahroudi21 and ketabi) that had a better yield and horticultural characteristics were screened to wilsonomyces carpoph...
Objective: A field experiment was conducted to assess the optimum inter- and intra-row spacing on growth, yield and yield component of roselle (Hibiscus sabdariffa L.) in 2014/15 cropping season at Wondo Genet Agricultural Research Center experimental site (at Wondo Genet station). Methods: Two inter-row spacings (60 and 90 cm) and three intra-row spacings (30,...
The present study was designed to explore the flavonoid contents and the radical scavenging activities of 50% ethanol extracts of leaves, stems, rachis and roots of Dryopteris erythrosora. The total flavonoid contents in various parts were determined as: stems > roots > rachis > leaves. All extracts from different parts of D. erythrosora showed strong bioactivities. The DPPH free radical scaven...
the effects of drought and salinity stress on the growth and chemical compositions pennyroyal(mentha pulegium l.) plant were investigated. this experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (fc)) and five salt treatments with 0, 25, 50, 75 ...
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
