environmental stresses, such as salinity can play an important role in disturbing different stages of plant growth, development, and especially seed germination in arid and semiarid regions in iran. turf grasses are highly dissipation in areas associated with saline soils and/or saline irrigation water. in order to study the effects of salinity on turf grasses germination, an experiment was con...

We discuss two precision experiments which will measure fundamental weak interaction parameters: MuLAN’s goal is the measurement of the positive muon lifetime to 1 ppm, which will in turn determine the Fermi coupling constant GF to 0.5 ppm precision. MuCAP is the first experiment which will unambiguously determine the induced pseudoscalar form factor of the proton, gP . While contradictory expe...

objective: to evaluate the effect of chemical stimuli on germination and seedling growth of caper (capparis spinosa) under drought stress. methods: factorial experiment in a completely randomized design with four replicates per treatment were performed. first factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/l), gibberellic acid levels (500, 250 and 125 ppm), a...

Carex divisa is a patrimonial rhizomatous species and acts as an important component of grazed wet permanent grassland on the French Atlantic coast. This study treated three storage regimes (wet-cold, dry-cold and dry-warm), burial in soil, fluctuating temperature and salinity on seed germination of C. divisa. The seeds were dormant at maturity. No seed germinated after 2 and 6 weeks of dry sto...

The aim of this study was to determine the effects of different plant growth regulators, NAA (0 mg/l, 50 mg/l and 100 mg/l) and GA3 (0 mg/l, 50 mg/l and 100 mg/l), with various boron concentrations (0 mg/l, 50 mg/l and 100 mg/l) on pollen germination of ‘Şaba’, ‘Rabie’ and ‘Padre’ almond cultivars in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different tr...

ABSTRACT: Couroupita guianensis Aubl. is an Amazonian forest species with important medicinal and ornamental value. This study evaluated the effect of different culture media light spectra on in vitro germination development zygotic embryos C. guianensis. The media, MS WPM, were without addition plant growth regulators associated four LED spectra: white (CW), 70% red + 30% blue (R2B), 100% (R),...

Sixty-nine Angus-sired steer calves (332.3 kg initial BW) were used to determine the effects of single or double implant strategies on steers of high or low genetic potential (GP) determined by the GeneMax (Zoetis, Florham Park, NJ) genetic profiling test. Steers were assigned to treatments in a 2 × 2 factorial design with factors of 1) composite GP score (high, mean GP score of 86.5 [HI]; low,...

a growth chamber study was carried out to evaluate the allelopahtic effects of shoot and root water extract of hoary cress (cardaria draba) on seed germination and seedling characteristic of sorghum (sorghum bicolor). the study was conducted based on completely randomized design with four replications in research laboratory of faculty of agriculture, university of birjand in 2008. treatments we...
