today, hormones and nutrients are used in order to improve vegetative and reproductive growth of many agricultural products in the world. the purpose of this study, was to increase fruit set, fruit weight, and finally, increase of yield along with improvement of vegetative growth with putrescine treatments (0, 0.01, 0.001m) and potassium nitrate (0, 2 and 4%) of quince (cydonia oblonga cv. esfa...

several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...

Marigold has special importance and application in landscape designing. Nowadays, various species and cultivars of this plant are grown in many climates, where different environmental stresses such as freezing, salinity and drought can lead to vegetative disorders. This study was carried out to investigate the interactions between salinity and ammonium nitrate on seed germination, vegetative gr...

A study was conducted to determine if nitrate sources in ground water (fertilizer on crops, fertilizer on golf courses, irrigation spray from hog (Sus scrofa) wastes, and leachate from poultry litter and septic systems) could be classified with 80% or greater success. Two statistical classification-tree models were devised from 48 water samples containing nitrate from five source categories. Mo...

γ-Cyclodextrin-metal-organic frameworks (γ-CD-MOFs) are developed as a new promising and biocompatible material, which shows great potential for drug delivery system (DDS) applications. γ-CD-MOFs were successfully synthesized using microwave-assisted technique from different potassium sources (KOH, KCl KNO3). The encapsulation of olivetol (OLV) into these materials was investigated an innovativ...

Objective: Tooth hypersensitivity often starts in early adulthood because of gum recession and loss of the cementum covering dentin. The purpose of this study was to compare the effect of toothpaste,1 containing triclosan, potassium nitrate, zinc citrate,2 triclosan, potassium nitrate,3 calcium sodium phosphosilicate (novamin) on gingival health, plaque formation and dentin hypersensitivity in ...
