Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...
A greenhouse experiment, as hydroponic, was carried out in order to investigate the response of sunflower genotypes (Hison125, Iroflor and Bliezer) to different levels of salinity (0, 60 and 120 mM of NaCl) and Fe (0, 50 and 100 mM) in nutrient solution. The experiment was arranged as factorial, based on a completely randomized blocks design with four replications. Results showed that plant hei...
In Iran, Acacia victoriae is not native to tree in Iran but it is used for important goals such as stabilize hills and the beautify landscape in the southern regions of the Iran, especially in the Khuzestan and Ilam provinces. Researches that include the development of native and non-native trees, which are compatible with the conditions of dusting areas in the western provinces of Iran, are ve...
Greenhouse experiments in a completely randomized design were carried out to investigate the effects of nitroxin fertilizer (0, 1 and 2 li/ha) on morphological and physiological traits of Amaranthus retroflexus in 2013. The traits in the study included plant height, fresh and dry weight of shoots, roots, stem and leaf, Chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, anthocyanin, a...
23 strains of rhizobia, from 14 leguminous species, were evaluated on a Thai cultivar of Voandzeia* in Leonard jar trials. The symbiosis ranged from completely ineffective through moderate effectiveness to fully effective. Bradyrhizobium sp. TAL 169, isolated from Vigna unguiculata, ranked most-effective; the widespectrum Bradyrhizobium strain CB 756 was ineffective. In a cultivar x Bradyrhizob...
the effect of tricyclazole application on waterlogging damage alleviation in canola seedlings was evaluated in a pot experiment in complete randomized design layout with three replications. treatments included: control (no waterlogging), waterlogging, tricyclazole plus waterlogging and tricyclazole. tricyclazole (75%) applied at three-leaf stage on canola seedlings. seedlings were exposed to wa...
in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...
This pot experiment was conducted to investigate the effects of ordinary and nano forms of zinc oxide on growth and ion content of four wheat cultivars (Niknejad, Iniya, Rowshan and Moghan2) under three salinity levels (0, 75 and 150 mM NaCl). In this experiment, shoot and root dry weight, and concentration of potassium, sodium and zinc in shoots were measured. Results showed that with an incre...
Soil salinity is an increasing environmental stress on crops in most areas of Iran since farmers use underground saline water for irrigation. In order to investigate the effects of salt stress on germination and seedling growth of safflower (Carthamus tinctorius L.), an experiment was conducted at two stages (germination seedling growth), using four levels of NaCl salinity (0, 5, 10, 15 ds/m), ...
in order to study, the effects of drought stress on germination and seedling growth of chickpea genotypes, experiments were carried out on two susceptible genotypes (mcc68, mcc448) and two resistant genotypes (mcc392, mcc877). in the first experiment the seeds were sown under different levels of drought stress (0,-0.4,-0.8,-1.2mpa) in 25◦c at the growth chamber with 4 replication. the results s...
