Water stress caused by drought affects the productivity of sugarcane crop. A breeding alternative is selection drought-tolerant cultivars. The objective this study was in vitro screening cultivars tolerant to water using polyethylene glycol (PEG) as a stressing agent. Cultivars (cv) Mex 69-290, CP 72-2086, 79-431 and MOTZMex 92-207 were subjected different concentrations PEG 6000 (0, 3, 6 9% w/...

This young man presented initially and repeatedly over a period of twenty years with symptoms of irritability, depressed and withdrawn mood, impulsivity, out-of-control behavior, and suicidal ideation and behavior. These symptoms occurred with disabling intensity at ages 3 year, 6 1/2 years, and 8 1/2 years, when he had not yet been adequately diagnosed and treated with appropriate psychopharma...

in this study, postharvest characteristics of eight cut rose cultivars (valentine, king pride, prima donna, black baccara, victory, papagayo, royal baccara and yellow island) were investigated in a growth room with temperature of 20 ºc, relative humidity of 50% and light intensity of 10 µmol m-2 s-1 in autumn 2008. among cultivars significant differences were found for all of the attributes eva...

the kashan erg is one of the most important sand dune complexes in iran. being affected by wind erosion, theerg's borderlands face numerous problems as a result of sand movement. to evaluate the risk of sands moving intoresidential areas near the kashan erg, anemometry data from synoptic stations located in kashan, ardestan, meimeh,naeen, and qom were collected and analyzed to calculate the san...

This work comprises the theoretical determination and validation of diagnostic standards for the analysis of saturated soil extracts for cut rose flower crops (Rosa spp.) growing in the Bogota Plateau, Colombia. The data included 684 plant tissue analyses and 684 corresponding analyses of saturated soil extracts, all collected between January 2009 and June 2013. The tissue and soil samples were...

Chrysanthemums represent the second most important cut flower after rose on global commercial market. The phenomenal importance and popularity of chrysanthemums have attracted breeders’ attention, resulting in release vast numbers cultivars. Identifying these cultivars is crucial to protecting intellectual property rights improving efficiency breeding. Distinguishing chrysanthemum genotypes bas...

The effects of various growing substrates, combinations of soil, silt, sand, press mud (PM) and rice hulls (RH) on plant growth, yield and quality of rose (Rosa hybrida L.) cvs. Kardinal, Anjlique and Gold Medal, were studied to standardize substrates for cut rose production and develop better management and quality production protocol. Plant height, number of leaves branch, leaf area, number o...
