in order to investigate the effects of mycorrhiza symbiosis and different nitrogen levels on yield, yield components and essential oil content and yield of fennel (foeniculum vulgare mill.) and ajowan (carum copticum l.), a field experiment was arranged in a factoriel based on a randomized complete block design with three replications at the agricultural research station, ferdowsi university of...
in order to possibility of improving physiological traits, yield and yield components of safflower (carthamus tinctorius cv. sina) by anti-transpiration application in rainfed condition, a research was carried out in factorial based on randomized complete block design (rcdb) with three replications in miyaneh region (east azarbaijan province - iran) in 2011. the treatments antitranspirant rate ...
We have examined the effects of mild, chronic water stress and acute water stress on two water stress sensitive plants, Xanthium strumarium and Helianthus annuus. Using a combination of the leaf disc O(2) electrode to measure the light responses of photosynthesis and 77 K fluorescence to monitor damage to the primary photochemistry, we have found the following: (a) The CO(2) saturated rate of p...
interrelationships between chlorophyll content and seed yield in bread wheat under saline conditions
the measurement of chlorophyll content of leaf is as an appropriate criterion in breeding programs to increase the rate of leaf photosynthesis. in order to study the relationship between chlorophyll content and seed yield under saline conditions, 41 wheat genotypes were evaluated in two conditions (normal and salinity stress) at the research field of the national salinity research center (nsrc)...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...
One of the major problems in recent years is the more dust storms occurrence in west regions of Iran in order to rising of the temperature and drought in the neighbored country (Iraq). In present investigation, effect of simulated dust storm on chlorophyll a fluorescence, chlorophyll content and phenol compounds surveyed in vitro in medicinal plan Thymus vulgaris. T. vulgaris is the aromatic me...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...
