Aluminium (Al) toxicity and drought are the two major abiotic stress factors limiting common bean production in the tropics. Using hydroponics, the short-term effects of combined Al toxicity and drought stress on root growth and Al uptake into the root apex were investigated. In the presence of Al stress, PEG 6000 (polyethylene glycol)-induced osmotic (drought) stress led to the amelioration of...

The adverse effects of salinity and PEG-induced water stress on growth of Matricaria chamomilla were assessed at the germination stage using osmotic solution of NaCl (0, -0.175, 0.358, -0.541, -0.716 MPa), and polyethylene glycol (PEG 6000) (0, -0.05, -0.1, -0.2, -0.3 MPa), respectively. Effect of NaCl salinity stress (0, 40, 80, 120 and 190 mM NaCl) at early growth stage of chamomile was also ...

The water relations of pepper plants (Capsicum frutescens L.) under conditions conducive to guttation were studied to evaluate the control of plant water stress with polyethylene glycols. The addition of polyethylene glycol 6000 to the nutrient solution resulted in water relations similar to those expected in soil at the same water potentials. Specifically, xylem pressure potential in the root ...

Chilli is an important vegetable and spice crop in India. It cultivated under both irrigated rainfed conditions. Most of the local genotypes are grown conditions they known to withstand drought some extent with lowered yield. Since chilli varieties or hybrids not developed for tolerance, experiment was conducted evaluate 34 collected from different regions tolerance using polyethylene glycol 60...

The Leuconostoc species require sucrose in the culture medium as an inducer for the elaboration of glucosyltransferase (GTF) and glucans. Among all the reported putification methods, polyethylene glycol (PEG) is a effective and single step purification method for GTF from Leuconostoc mesenteroides. The extracellular GTFs from Leuconostoc mesenteroides L.m.28 and mutant Leuconostoc mesenteroides...

nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...

drought is one of the most important abiotic stresses affecting plant growth and development. in the present study, the changes in lipid peroxidation rate and antioxidant enzyme activities were determined at different concentrations of polyethylene glycol (peg) 6000 (0, 5, 10, and 15% (w/v)) for two canola cultivars (slm046 and hyola 308). in order to produce water deficit, 12 days old canola s...

Objective- The aim of this study was to evaluate the efficacy and safety of senna as an alternative or adjunct to polyethylene glycol (PEG) solution in dogs using colonoscopy and radiography.Design - Experimental study.Animals - 20 adult mongrel healthy dogs.Procedures- Dogs were randomly allocated to receive 1 of 4 different bowel preparation regimens including PEG, senna or ...

Effect of salts (Na2SO4, Na2CO3, MgSO4, NaCl, MgCl2), soil extract and polyethylene glycol (PEG-6000) on the germination of Chenopodium glaucum L., seed was studied. Maximum germination was obtained in distilled water. Germination decreased with increase in salinity. The inhibition of germination by salt solutions was in the order of MgCl2 > Na2SO4 > Na2CO3 > NaCl > Soil extract > MgSO4. Germin...

silicon is known to ameliorate the deleterious effects of drought on plant growth. we evaluated growth of wheat (triticum aestivum l. cv. chamran) under water-deficit stress induced by polyethylene glycol as affected by si application. in this article, the effects of si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (rwc), electrol...
