in order to investigate the effects of plant growth promoting bacteria on growth characteristic of wheat, an experiment was conducted at the research greenhouse, faculty of agriculture, ferdowsi university of mashhad, iran, in year 2009. a completely randomized design based on factorial arrangement (3×6) with three replications was used. the first factor consisted of three cultivars of wheat (c...

The present study was conducted to investigate the effect of growth regulator NAA on in vitro shoot proliferation, rooting, and plantlet establishment. Among the different concentrations of NAA, the best increase in shoot weight (0.25 g) and shoot number (8.83) were observed from 0.1 mg/I NAA. The highest shoot length (2.60 cm), number of leaves (4.83), number of roots (5.15), and root length (...

In the present study, small segments of cotyledon, apical bud, hypocotyl, and root of 10-day-old seedlings were isolated and transferred to Murashige and Skoog (MS) base medium with different treatments of phytohormones. Two media were used for apical bud culture: MS with indole-3-acetic acid (IAA) and kinetin (Kin) (1 mg/l) and the other medium, MS with double vitamin of MS and 6-benzylaminopu...

In order to investigating the effect of different tobacco cultivars residue on germination and seeding growth of soybean an experiment was conducted at laboratory and glasshouse in college of Sari Agricultural Sciences and Natural Resources University during 2007 as a factorial based on completely randomized design with four replications. Extracts of root and shoot from two different types of t...

in other to evaluation of morphological and phenological traits of 24 populations, from four species chamomile of the genus of anthemis, an experiment were carried out using randomized completely blocks design (rcbd) in three replications in alborz research station in karaj, iran during 2011-12. 13 traits including: length and width of canopy diameter, plant height, number of flower, shoot fres...

The study was made in order to evaluate the response of fifteen wheat genotypes (grown in Pakistan) to sodium chloride salinity at seedling stage keeping two levels of salinity (150 and 200 mM NaCl) along with a control (no application of salt). The effect of varieties on shoot length of wheat was non significant. Maximum shoot length was recorded in MH-97 (15.55cm) while minimum shoot length w...

Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...
