Considering the increasing trend of saline land enhancement and lack of appropriate agricultural lands, identifying salt resistant plants such as fenugreek, which is an important medicinal plant, is important. To do so, a factorial experiment was conducted in the form of randomized complete blocks design with three replications on three fenugreek landraces (Yazd, Shiraz and Hendi) and five sali...

The physiological roles of PAs (putrescine, spermidine, and spermine) were investigated for their ability to confer salt tolerance (200 mM NaCl, 48 h) in mung bean seedlings (Vigna radiata L. cv. BARI Mung-2). Salt stress resulted in Na toxicity, decreased K, Ca, Mg, and Zn contents in roots and shoots, and disrupted antioxidant defense system which caused oxidative damage as indicated by incre...

a factorial experiment based on completely randomized design (crd) was performed with three replications to investigate the interaction between salinity and nh+4 / no-3 ratio on olive saplings. four levels of salinity (0, 50, 100,150 mm) and different ratios of nh+4/ no-3 (0:14, 2:12, 4:10, 6:8) were applied on one-year old olive saplings grown in perlite: sand media (1:1). results indicated th...

چکیده تنش شوری یکی از مهم ترین تنش های محیطی است که بسیاری از فرآیندهای زراعی، تغذیه ای، فیزیولوژیکی و بیوشیمیایی گیاهان را متاثر می سازد. در این آزمایش پاسخ 12 لاین آفتابگردان به تنش کلرید سدیم (0، 100 و 200 میلی مولار) در سیستم کشت هیدروپونیک مورد مطالعه قرار گرفت. در خلال اعمال تنش و پس از انجام آن (30 روز) شاخص های رشد، نفوذپذیری نسبی غشا (rmp)، وضعیت آبی گیاه، غلظت کلروفیل، فلورسانس کلروف...

Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...

Sugarcane grown under a wide range of agro-climatic conditions accounts for ~80% the sugar production worldwide. Since sugarcane productivity is severely affected by abiotic stresses and hence, an experiment was conducted two consecutive years during 2020 2021 on popular sub-tropical varieties. The laid out in two-factorial RBD consisting nine genotypes (Co 98014, Co 0118, 0238, 05011, 06034, 0...

Introduction: To assess the salivary composition of proteins and minerals in smokers compared with non-smokers.   Materials and Methods: In this study we compared the total protein and Ca, Na, K, Mg, Pb of whole saliva in two groups of men (28 smokers and 31nonsmokers) aged between 29-41years.   Results: Fifty-nine participants were evaluated. The mean age was 33.14±5.32 years among smo...

oeeuring in the Sangan arca was fonned within two different rock groups· graitoids and skarns. Based on the new amphibole classification and nomenclature, the general fonnula of amphibols IS (AB2C,T,O"OH),. Amphibole of granitoids is a ferroedenite in which Si = 6.87 - 7.75, CaR> 1.5, (Na+K)A > 0.5 and Ti < 0.5. Skarn amphiboles are mostly developed within amphibole skarns and gamet-pyr...

Despite considerable investigations of diurnal water use characteristics in different plant functional groups, the research on daily water use strategies of woody bamboo grasses remains lacking. We studied the daily water use and gas exchange of Sinarundinaria nitida (Mitford) Nakai, an abundant subtropical bamboo species in Southwest China. We found that the stem relative water content (RWC) a...

This research was conducted to evaluate effects of mycorrhiza fungi and nano zinc oxide on agro physiological traits of wheat under salinity stress based on factorial experiment according complete randomized block design with three replications under greenhouse condition at 2014. Treatments included salinity in three levels [no-salt (S0) or control, salinity 40 (S1) and 80 (S2) mM NaCl], two le...
