Drought is one of the major stress factors affecting growth and development plants, responsible for considerable crop yield losses worldwide. An experiment was conducted to compare three rice (Oryza sativa L.) varieties (BRRI dhan49, BRRI dhan71 dhan75) drought tolerance based on some parameters physiological status in germination stage. imposed by five levels polyethylene glycol (PEG) (0%, 10%...

Objective: To evaluate ten triticale genotypes to assess the quality of seeds under two production systems, with cut and without cut, in municipalities Matamoros (L1) Francisco I. Madero (L2), Coahuila,Mexico.Design/Methodology/Approach: The agronomic variables evaluated were: Grain yield (GY), number per spike (NSS), length (SL), spikelets (SS) plant height (PH). Variables laboratory normal se...

soil and water salinity in arid and semi-arid regions, is one of the most important stresses, can severely limit crop production. black cumin (nigella sativa l.) is annual important herbal plant in rununculaceae family that sense to salinity. this study was conducted to evaluate the effects of the priming on seed germination of black cumin under saline stress. the experiment was carried out as ...

chamomile (matricaria recutita) is a highly valuable medicinal and aromatic plant of asteraceae family and its anthodia used frequently in pharmaceutical and cosmetic industries. the aim of this study was the evaluation the effect of drought stress induced by polyethylene glycol 6000 (peg) on germination percentage, germination rate, plumule and radicle length of four improved cultivars of germ...

Present study was conducted to investigate whether plant growth regulators viz. salicylic acid and ascorbic acid can alleviate the adverse effects of drought stress on germination and seedling growth of two sunflower hybrids (Hysun-33 and Hysun-38). Two (-0.06 MPa and -0.12 MPa) levels of drought stress were created by adding different concentrations of (PEG8000) polyethylene glycol in growth m...

Sunflower is a potent allelopathic plant which possesses important allelochemicals with known allelopathic activity on other plants. In this study, allelopathic effects of fresh aqueous extracts (FAE) and air dried aqueous extracts (DAE) of root, shoot and leaves of sunflower (Halianthus annuus L.) were investigated on germination and seedling growth of wheat (Triticum aestivum L.) and maize (Z...

A cDNA encoding a nucleolar protein was selected from a pea (Pisum sativum) plumule library, cloned, and sequenced. The translated sequence of the cDNA has significant percent identity to Xenopus laevis nucleolin (31%), the alfalfa (Medicago sativa) nucleolin homolog (66%), and the yeast (Saccharomyces cerevisiae) nucleolin homolog (NSR1) (28%). It also has sequence patterns in its primary stru...

in order to study the effects of different levels of drought stress and plant growth promoting rhizobacteria on the germination indices of seeds harvested from wheat (tritium aestivum l.) cv. sayonz in the field treated with different levels of nitrogen, in controlled conditions, a factorial layout based on completely randomized design with three replications, was conducted. treatments included...

Abstract The goal of this study was to look into growth changes and a number metabolic events in Fe 2+ treated Lupinus albus, Triticum aestivum , Vicia faba, Zea mays plants assess the role biosorption by Rhodotorula mucilaginosa YMM19 alleviate these changes. effect concentrations (untreated with biosorbent) on seed germination studied. T. plumule stimulated low dose . However, application red...

REMATURE germinating seeds have been observed in various plants, including P lemons, oranges, melons, wheat and rye. However, in none of these is there any good indication that the premature germination is the result of changes in the germ plasm. Only in maize has the genetic control of this phenomenon been clearly demonstrated. Such mutants have been described by MANGELSDORF (1923,1926, and 19...
