23 strains of rhizobia, from 14 leguminous species, were evaluated on a Thai cultivar of Voandzeia* in Leonard jar trials. The symbiosis ranged from completely ineffective through moderate effectiveness to fully effective. Bradyrhizobium sp. TAL 169, isolated from Vigna unguiculata, ranked most-effective; the widespectrum Bradyrhizobium strain CB 756 was ineffective. In a cultivar x Bradyrhizob...

in order to study the effect of soil compaction on root and shoot growth of wheat plants (shahriar variety), a greenhouse pot experiment was conducted in guilan university. the study design was factorial with completely randomized in three replications. treatments included three compaction levels; (normal compaction, compaction of ten percent and twenty percent) and two type of soil texture (cl...

dodder is an obligate parasite of many plant families and among dodder species cuscuta campestris has the most diverse around the world. extensive infestation to dodder recently has been reported in some sugerbeet production regions of khorasan provinces. so, in this study greenhouse and field experiments were conducted to test and charachterize the tolerance of commercial sugarbeet varieties t...

Research pertaining to genetic variability parameters, heritability, and genotypic, phenotypic, simple, and environmental correlations for various seedling traits in five elite advanced cotton (Gossypium hirsutum L.) lines (FH-113, FH-114, FH-941, FH-942, and FH-2015) and one check (CIM-496) was carried out during October and November 2010 under greenhouse conditions at the Cotton Research Inst...

abstract this research was conducted to evaluate the effect of gibberellic acid (ga3) (0.250, 500 and750 mg l-1) on vegetative growth of olive sapling (olea europaea l) in 2004-05 at shahid chamran university of ahvaz. the experiment was a completely randomize design with 4 replications. parameters measured were: shoot height, inter-node length, leaf and root area, fresh and dry weight of shoot...

BACKGROUND AND AIMS The distribution of canopy growth among different shoot types such as epicormic, long and short shoots is not well understood in the peach tree. In this experiment, the effects of crop load and early epicormic sprout removal on current and subsequent-year distribution of vegetative growth among epicormic, long and short shoots was investigated in Prunus persica. METHODS Fi...

The watermelon [Citrullus lanatus (Thunb.) Matsum. and Nakai] cultivar Crimson Tide and 7 different gourd genotypes [Cucurbita maxima, C. moschata, Luffa cylindrica, Benincasa hispida, Lagenaria siceraria landraces (Skp and Birecik), and L. siceraria hybrid (FRGold)] with rootstock potential for watermelon were grown under saline conditions (0, 4, 8, 12, and 16 dS m) to investigate the response...
