In order to determine the impact of thermo priming on germination of soybean seeds, an experiment was conducted as a completely randomized design with three replications. The factors of studied included different time thermo priming (control, 5 and 10 minutes) through the placing seeds were exposed to oven. The results showed that the effect of thermo priming was significant on germination perc...

ABSTRACT The aim of this study was to verify the influence previous crops and fungicide seed treatment in incidence control damping-off caused by Rhizoctonia solani cotton seedlings under greenhouse conditions. This experiment carried out during two years at Embrapa Western Agriculture, Dourados, Mato Grosso do Sul State, Brazil. In addition (treated untreated seeds) fallow, following cover wer...

local site conditions have a strong effect on ground response during earthquakes. two important soil parameters that control the amplification effects of seismic motions by a soil column are the soil hysteretic damping ratio and shear wave velocity. this paper presents the results of in situ damping ratio measurements performed using continuous surface wave attenuation data at a site in semnan ...

damping of a full-scale cable with a pair of passive–on magnetorheological (mr) dampers was tested. a cable of 215.58m long with the first mode frequency of 0.658hz was tensioned horizontally in cable prefabrication factory. two mr dampers were attached to the cable in an angle in the plane perpendicularly to the cable axis in 5m length from the cable anchorage. the applied voltage level was 0v...

The success of seedling establishment of desert plants is determined by seedling emergence response to an unpredictable precipitation regime. Sand burial is a crucial and frequent environmental stress that impacts seedling establishment on sand dunes. However, little is known about the ecological role of seed mucilage in seedling emergence in arid sandy environments. We hypothesized that seed m...

Seed and seedling predation may differentially affect competitively superior tree species to increase the relative recruitment success of poor competitors and contribute to the coexistence of tree species. We examined the effect of seed and seedling predation on the seedling recruitment of three tree species, Acer rubrum (red maple), Liriodendron tulipifera (yellow poplar), and Quercus rubra (n...

This study was carried out to determine the resistance levels of some onion genotypes in Yalova gene pool by Fusarium testing during seedling stage. The isolate used oxysporum f. sp. cepae, which causes damping off stage and later basal rot bulbs. variance analysis for test mean differences against control were analyzed using General Linear Model Tukey test. germination rate seeds varied betwee...
