To determine the effect of salt stress on seed germination of Leymus species, seeds of Leymus racemosus (Lam.) Tzvel., Leymus angustus (Trin.) Pilger, Leymus multicaulis (Kar. et Kir.) Tzvel., Leymus duthiei (Stapf) Y. H. Zhou et H. Q. Zhang and Leymus secalinus (Georgi) Tzvel. were treated with NaCl solutions of different concentration: 0 mmol/L, 100 mmol/L, 200 mmol/L, 300 mmol/L, 400 mmol/L ...

to study the effects of sowing dates on seed germination and on seed vigor of 12 spring rapeseed cultivars, an experiment was performed in years 2005-2006. during the first year, 12 cultivars of spring rapeseed were planted in the research field of seed and plant improvement institute, karaj, iran. during the second year, standard germination test was conducted to study the performance of the s...

Hypoglycemic effect is an efficient means to modulate elevated blood glucose levels in patients with diabetes. We found that the extract of lotus plumule (the germ of Nelumbo nucifera Gaertn. seed) showed potent glucose uptake enhancement activity against L6 myotubes, which results in a hypoglycemic effect. This activity was further investigated, and an active constituent was identified as a si...

abstract in order to study the effects on salinity and silicon application on yield and yield components of purslane (portulaca oleracea l.), an experiment was conducted in a completely randomized desgin with three replications and two factors consisted of four different levels of salinity using nacl (0, 7, 14, 21ds/m) and two levels of silicon (application of one mmol sodium silicate and not a...

topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. in order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of rcb design with 3 replications was conducted in 2011 at the tobacco research farm of isfahan. treatments were including topping time (t1: topping at e...

salt stress is one of the most chalanging abiotic stresses affecting natural productivity and causing significant croplosses worldwide. a greenhouse experiment was conducted to evaluate the response of two alfalfa cultivars (bamiand hamedani) to 6 levels of salinity (0 as control, 25, 50, 75, 100, 125 mm nacl) at the college of agriculture,shiraz university, shiraz, iran in 2008. plant dry weig...

this research was carried on in order to investigate the response of wheat cultivars to salinity tension as factorial experiment and in complete randomized block design in four replications in islamic azad university shoushtar branch. in this experiment the response of nine wheat cultivars including chamran, karchia66, mahoti, roshan, alvand, kavir, ghods, atrak and tjan at vegetative growth st...

intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

OBJECTIVE Volume overload from an incorrect assessment of dry weight leads to cardiovascular diseases in chronic hemodialysis patients. Dry weight assessment in pediatric is difficult for a number of reasons including growth. Blood volume monitoring (BVM) has been proposed as an accurate method of estimating dry weight in adult. However, there is very scant data regarding B VM assessment in ped...
