the effects of sodium chloride (nacl) salinity (control; canal water with 0.4 ds m-1), 2.5 dsm-1, 5.0 ds m-1, 7.5 ds m-1 and 10.0 ds m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (rosa hybrida l.) cultivars viz. ‘kardinal’, ‘angelique’ and ‘gold medal’ were studied to achieve better management, quality product...

background & aim: kelussia odoratissima mozaff. (apiaceae) is one of the medicinal plants and endemic in zagros mountains, iran, which unfortunately due to illegal harvest is endangered. in order to break dormancy and to evaluation of effect of different treatments on traits a factorial experiment base on completely randomized design was created on the seed zone sar-aghaseyed functions in c...

To evaluate the population variation, individual plasticity, and local adaptability of Solidago canadensis in response to shade treatment, we conducted a common pots experiment with a total of 150 ramets (5 genets, 15 populations, and 2 treatments) subjected to both control (natural light) and shady treatment (10% of natural light). Shade treatment significantly reduced growth and content of de...

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...

the use of heavy machinery in forestry operations such as logging has increased worldwide during the last decades. however, these machines may seriously influence the soil ecosystem as they induce rutting, disturbing the upper soil layers, and soil compaction. severe compaction of soil adversely affects the growth of plants.this study was done by using a penetration resistance experiment in a g...

The effects of sodium chloride (NaCl) salinity (control; canal water with 0.4 dS m-1), 2.5 dSm-1, 5.0 dS m-1, 7.5 dS m-1 and 10.0 dS m-1, respectively) developed after 6 weeks of pruning (beginning of study) on plant growth, flowering and quality of three cut rose (Rosa hybrida L.) cultivars viz. ‘Kardinal’, ‘Angelique’ and ‘Gold Medal’ were studied to achieve better management, quality product...

Many agriculturally important traits are complex, affected by many genes and the environment. Quantitative trait loci (QTL) mapping is a key tool for studying the genetic structure of complex traits in plants. In the present study QTLs associated with yield and agronomical traits such as leaf number, leaf length, leaf width, plant height, stem and head diameter were identified by using 70 recom...

considering importance of baby corn as a new food, this study was conducted to evaluate effect of different sowing date; planting density and harvest methods on growth and yield of baby corn ksc403su varieties in agricultural research center and natural resources of khorasan razavi province during on 2007-2008. was considered at three levels of sowing date (14th  june, 3th  july, 24th july) as ...
