nowadays, tobacco is considered as one of the important world industrial plants. in the present study, for a creation of somaclonal variation, calli were produced on ms medium supplemented by 2 mg/l of naphthalene acetic acid (naa) and then regenerated on ms medium supplemented with 1 mg/l benzyl amino purine (bap) and 0.1 mg/l of naa. to determine correlations among traits and to fit multiple ...

according to the contradictory reports of researchers, tillers may have positive or negative effect on wheat yield. thus, this study was conducted to investigate the role of tillers on wheat yield under two row spacing of 12.5 and 25 cm and four plant densities of 125, 250, 375 and 500 plants per m2, at gorgan university of agricultural sciences and natural resources farm in anbare-ololum reign...

In order to determine the responses of morphological characteristics, yield and yield components of rapeseed (Brassica napus L.) to plant density and weed interference duration, a factorial experiment was conducted using a randomized complete block design with 3 replications at the Rice Research Institute of Iran (RRII) in Rasht, in the 2008 growing season. The factors comprised plant density a...

to study the effects of plant density and nitrogen rates on the ability of canola (regent  cobra; an inbred variety) to compete with weeds, an experiment was conducted as a factorial complete block design with four replications. the treatments included four levels of plant density at 150, 190, 230, and 270 plants m-2, and four levels of nitrogen (n) fertil-izer at 0, 46, 92, and 138 kg ha–1. r...

Strigolactone (SL) mutants in diverse species show reduced stature in addition to their extensive branching. Here, we show that this dwarfism in pea (Pisum sativum) is not attributable to the strong branching of the mutants. The continuous supply of the synthetic SL GR24 via the root system using hydroponics can restore internode length of the SL-deficient rms1 mutant but not of the SL-response...

in order to understand the effect of plant density and different fertilizers on sesame (sesamum indicum l.) production, an experiment was conducted as a factorial arrangement based on completely randomized block design with three replications. the experimental treatments were fertilizers in four levels (cow manure (30 t.ha-1), municipal compost (30 t.ha-1), chemical fertilizer (250 kg ammonium ...

introduction growth analysis has been widely used in breeding programs to identify the important plant developmental phases and components related to higher yield under a particular set of environmental conditions. castor bean (ricinus communis l.) is an important commercial crop. castor oil based by products is used in manufacturing of several commercially important commodities like surfactant...

Maize is a globally important food, feed crop and raw material for the food and energy industry. Plant architecture optimization plays important roles in maize yield improvement. PIN-FORMED (PIN) proteins are important for regulating auxin spatiotemporal asymmetric distribution in multiple plant developmental processes. In this study, ZmPIN1a overexpression in maize increased the number of late...

in order to evaluate the genetic diversity and identify quantitative trait loci(qtl) controlling agro-morphological triats such as leaf length, leaf width, leaf number, internode distance, dried leaf yield per plot, plant height and stem girth, the genetic population including 225 f 2:3 families from the cross between two oriental-type tobacco genotypes ‘spt 406 (paternal) × basma seres 31 (mat...
