Among the most common abiotic stresses that retard development and growth of plants is salt stress. This study examined impact various levels (NaCl Na2SO4) on germination behaviour sesame cultivars. Under simulated concentrations (0.05M, 0.01M, 0.15M, 0.2M, 0.25M, 0.3M, 0.35M, 0.4M, 0.5M), degree salinity tolerance two cultivars, viz., GT-10 JTS-8 were assessed. The radicle, hypocotyl length, f...

Common purslane (Portulaca oleracea L.) seeds show light-controlled dormancy. Ribosome profiles from dark-incubated seeds consist of 22 to 26% polysomes. Light induces germination and stimulates polysome formation during the 12-hour lag period preceding radicle protrusion. Polysome levels increase to 29, 35, and 41% with exposure to 3, 6, and 9 hours of light, respectively. Although polysomes f...

In the present work, we analyzed the histochemical aspects of Passiflora edulis seeds reserve mobilization during the first ten days of germination. Our results showed that mainly lipids present in the endosperm are used as a reserve source, and their levels reduce at the same time the radicle protrudes, between the fourth and sixth day of sowing. Furthermore, protein bodies are present in the ...

Abstract An insect-pathogen fungus called Beauveria bassiana (Balsamo) Vuill. is employed as a biological control for variety of insect pests. B. not only acts an entomopathogen, directly infecting and killing pests, but it also has the ability to live endophyte on plants, colonize plant tissues, consequently boost growth. This research was undertaken find out whether can cabbage what impact se...

This study was carried out to determine the response of birdsfoot trefoil salt stress during germination and seedling growth. The seeds (Sarıyıldız variety) used as material. In study; 6 different doses NaCl (pure water (control), 250 ppm, 750 2500 5000 10000 ppm) applied emergence. Germination experiment in darkness (20±2 °C) petri dishes according completely randomized design with 4 replicati...

This study was conducted to assess the correlation between growth response, phytoaccumulation factor of different tissues, and elemental composition in tomato seedlings exposed acid mine water (AMW). In pairwise determinations values plant height, stem diameter, seed germination indices (radicle length, final percentage (FGP), emergency rate index (ERI), vigour (VI), (G%) (GRI)) compositions (C...

an experiment was conducted to study the effect of sulfuric acid, temperature scales and the source of seed on to break hardness alfalfa seed (medicagoscutellatacvrobinson). this study was carried out as a factorial experiment based on randomized complete design with four replications at the agricultural collage of lorestan university in 2005. acid treatment as the first factor (to rinse with a...
