in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...

Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...

A pot experiment was conducted to evaluate the effect of synthetic wastewater containing various concentrations of cadmium and chromium on Eucalyptus camaldulensis. Six month-old seedlings of E. camaldulensis were treated with Cd (II) and Cr (VI) for 18 months. Treatments were; T0: (Tap water, control), T1: 0.05 +1.0 mg L, T2: 0.10+2.0 mg L, T3: 0.20+4.0 mg L and T4: 0.40+8.0 mg L of Cd and Cr ...

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...

dodder is an obligate parasite of many plant families and among dodder species cuscuta campestris has the most diverse around the world. extensive infestation to dodder recently has been reported in some sugerbeet production regions of khorasan provinces. so, in this study greenhouse and field experiments were conducted to test and charachterize the tolerance of commercial sugarbeet varieties t...

The root : shoot ratio for Ilex cassine L. grown 7 months in copper-treated containers was less than in nontreated containers. There was less dry weight for roots <5 mm in diameter in copper-treated containers than in nontreated containers in the outer 1 cm of the rootball. Dry weight of roots >5 mm in diameter within the rootball were not affected by copper hydroxide treatment. Coating the int...
