This study was conducted to determine the effect of foliar salicylic acid (SA) and citric acid (CA) applications on growth, biochemical characteristics and essential oil content of thyme (Thymus vulgaris L.) grown under field conditions. Salicylic acid (0.5 and 1 mM) and citric acid (5 and 10 mM) were applied three times during the vegetation at 15 day intervals. Results revealed that foliar ap...

gerbera is one of the ten important cut flowers in terms of production and consumption in the world and iran. in this research effects of foliar application of salicylic acid and thiamine on biochemical characteristics of gerbera flower were investigated. this experiment was conducted in a completely randomized design with four replications in the greenhouse commercial of the golazin maghsoud c...

Quality of measurements is an important factor affecting the reliability of analyses in environmental sciences. In this paper we combine foliar measurement data from Finland and results of multiple measurement quality tests from different sources in order to study the effect of measurement quality on the reliability of foliar nutrient analysis. In particular, we study the use of weighted linear...

Continuing to fertilize bareroot and container seedlings during the hardening process (from cessation of height growth until lifting) can improve seedling viability. The process of fertilizing during hardening has many names, but in the last decade a new term, nutrient loading, has come into use. The process of nutrient loading seedlings leads to luxury consumption indicated by foliar nitrogen ...

ABSTRACT Low vigor of longleaf pine has been reported at Fort Benning in Georgia, and Eglin Air Force Base in Florida. In an effort to determine the cause of this problem, foliar nutrition was assessed. Results indicated that macroand micronutrients were generally sufficient regardless of vigor status. Foliar Mn, however, was elevated at both locations. Excess Mn has the potential to interfere ...

Plants depend upon both genetic differences and phenotypic plasticity to cope with environmental variation over different timescales. The spatial variation in foliar δ(13)C levels along a moisture gradient represents an overlay of genetic and plastic responses. We hypothesized that such a spatial variation would be more obvious than the variation arising purely from a plastic response to moistu...
