The application of exogenous proline and glycinebetaine (betaine) confers salt tolerance on plants under salt stress. The effects of exogenous proline and betaine on apoplastic flow in rice plants under saline conditions were investigated using trisodium-8-hydroxy-1,3,6-pyrenetrisulphonic acid (PTS), an apoplastic tracer. Rice plants took up more PTS under light conditions than under dark condi...

The tobacco alkaloid nicotine possesses a molecular structure by which it may be related empirically to the amino acid proline. Proline is a-pyrrolidinecarboxylic acid. Nicotine may be considered as an N-methylated proline containing a 3-pyridine rino attached to the alpha position in place of the carboxyl. These similarities have been pointed out by TOTTINGHAM (9) and have been employed by TRI...

Laser is one of the sources that induce a biological effect in higher plants. The positive effect of laser on some crops has been proved. This research was carried out to study the effect of laser radiation on the accumulation of proline in spring wheat (Triticum aestivum cv. Kavir) under different NaCl treatment levels. Semi-coherent red beam, infrared beam and one-second harmonics of Neodymiu...

Exposure to electromagnetic fields (EMF) has become an issue of concern for a great many people and is an active area of research. Phytoplasmas, also known as mycoplasma-like organisms, are wall-less prokaryotes that are pathogens of many plant species throughout the world. Effects of electromagnetic fields on the changes of lipid peroxidation, content of H(2)O(2), proline, protein, and carbohy...

to study the effect of humic acid and drought stress on some physiological characteristics of roselle (hibiscus sabdariffa) an experiment was conducted in the research field of agricultural education centre of jiroft in 2013. field experiment was carried out as split plot design with three replications. water deficit stress as main factor with three levels (a1 = irrigation after 50, a2 = 100 an...

Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...

The effect of various NaCl treatments (0, 50, 100, 200 and 300 mM) at different growth and development stages (tillering, boot swelling, flowering and polination) of two wheat cultivars (Ghods : salt-sensitive; Boolani : salt-resistant) on proline concentration and the kinetic activity of proline dehydrogenase was studied under greenhouse conditions. Generally, in response to salinity treatment...

basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment  investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...

to study some physiological and morphological traits of sugar beet varieties in response to salinity stress, three multi-germ sugar beets (13030, 22393 and ic) were grown in the greenhouse, faculty of agriculture, shahid chamran university, in 2009. the experiment was carried out under three levels of salinity in from of sodium chloride source, that included control (zero), 100 and 200 mm uses ...

application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. nanofertilizers application could be a suitable way to reduce these problems. accordingly, in order to assess the silicon nanopar...
