rose flower (rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. to study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of alandasht, astane ghods garden, mashhad, iran, during 2009-2010. the first factor was six cultivars of rose flower ...

Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was eva...

the aim of this reaserch was evaluathng the aluminum-sulphate concentration levels in preserved solution with stem recutting on longevity of rosa hybrida cv. varlon cut flowers. the investigation was conducted in horticultural lab,agriculturalcollege,zanjanuniversity. rose cut stems were produced in greenhouse from biennial mother stocks and were placed under the treatment of aluminum-sulphate ...

erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...

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...
