Activity of endogenous auxins and growth inhibitors, gibberellins and cytokinins was observed in the extracts of seedlings of Pisum sativum under NaCl stress. After 6 days of germination, when Pisum sativum seedlings were subjected to low concentration of NaCl (50 mM) or boron (10 ppm) increased the endogenous growth regulating substances. Higher concentration of NaCl (150 mM) decreased endogen...

Paclobutrazol (PBZ) is one of the most important triazole compounds. This compound increases plant tolerance to environmental stresses. A study aimed to investigate the effects of PBZ on morphological and biochemical traits of euonymus (Euonymus japonicas) exposed to NaCl stress. Plants were treated with three levels of PBZ (0, 500 and 1000 mg L-1) and four levels of NaCl (0...

The turf grass Pennisetum clandestinum Hochst. (kikuyu grass) is one of the candidate plants for utilization and reclamation of salinized areas. The capability of kikuyu grass to grow under saline conditions was tested during 6 months, under various irrigation treatments (tap water control, 80-mM, 150-mM, 200-mM, 240mM NaCl). Plant biomass production was visibly affected only at NaCl concentrat...

UNLABELLED Previously we demonstrated that arginine vasopressin (AVP) directly inhibits bicarbonate absorption (JHCO3, pmol/min per mm) in the medullary thick ascending limb (MTAL) of the rat. To determine whether changes in osmolality also may affect bicarbonate absorption, MTAL were studied in vitro with 25 mM HCO3- solutions. Control osmolality was 290 mosmol/kg H2O. In the absence of AVP, i...

Five-week-old tomato plants (Lycopersicon esculentum) cv. Perkoz grown in pots containing garden soil in a growth chamber were submitted to 50 or 150 mM NaCl for 1 h, 2 and 5 days. Tomato leaf anatomy generally did not change after short time salinity, except 5-day-treatment with 150 mM NaCl, where changed cell shape (shrunk and deformed) simultaneously with increased volume of intercellular sp...

The influence of exogenous ascorbic acid (0.5 mM) in counteracting NaCl-induced cellular alteration of onion bulb inner epidermis was investigated. Plasma membrane permeability, protoplasm swelling and cell viability were measured under the effect of 150 mM NaCl in presence and absence of ascorbic acid. Ascorbic acid was added simultaneously with salt or before salt treatment. Salt stress at 15...

Hydroxyapatite column chromatography can be used to purify filamentous bacteriophage--the phage most commonly used for phage display. Virions that have been partially purified from culture supernatant by two cycles of precipitation in 2% polyethylene glycol are adsorbed onto the matrix at a density of at least 7.6 x 10(13) virions (about 3 mg) per milliliter of packed bed volume in phosphate-bu...

Jiang, Y., J. Tang, X. Yu and J. Camberato. 2013. Growth and Physiological Responses of Diverse Perennial Ryegrass Accessions to Increasing Salinity. 2012 Annu. Rep. Purdue Univ. Turfgrass Sci. Progr. p. 7-11. Summary: Ten diverse accessions of perennial ryegrass (Lolium perenne L.) were grown in sand culture and exposed to a half-Hoagland solution amended with 0 (control), 50-, 100-, 150-, 200...

In order to evaluate the effects of seed priming with salicylic acid (SA) (0, 2, 10, and 20 mM) to increase salt tolerance (0, 50, 100, 150, and 200 mM NaCl) in medicinal plant Dracocephalum moldavica at seed germination, an experiment was conducted as factorial in a completely randomized design with four replicates. The assessed parameters included germination percentage and rate, len...
