Abstract Background Photosynthetic pigments participating in the absorption, transformation and transfer of light energy play a very important role plant growth. While, spatial distribution foliar is an indicator environmental stress, such as pests, diseases heavy metal stress. Results In this paper, situ quantitative visualization chlorophyll carotenoid was realized by combining Raman spectros...
Uncontrolled use of fossil fuels in industries and the transport sector has led to an increase in concentrations of gaseous pollutants such as sulphur dioxide (SO2), nitrogen dioxide (NO2) and their derivatives and ozone (O3). In addition to dry and wet deposition of these gases has been the major route of influx in ionic form into the ecosystem. This investigation was evaluated the effects of ...
In order to evaluate the foliar application of sodium nitroprusside on some morphological and biochemical properties of Alstroemeria cultivar Orange Queen, a research was conducted in a completely randomized design with 3 replications under hydroponic cultivation in the research greenhouse of Urmia University. Sodium nitroprusside was sprayed at concentrations of 0, 50, 100 and 200 μM. At the e...
effect of gibberellic acid on marigold (calendula officinalis l.) was evaluated in a pot culture experiment. a factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. main factor was foliar application stages (first, second and third) and sub factor included different concentrations of ga3 (0, 50, 150 and 250 mg l-1). results sho...
