The present study was aimed to investigate the response of the growth and physiological parameters of stevia (Stevia rebaudiana Bertoni) medicinal plant to salinity stress using a pot experiment in 2014. Ten levels of salt stress (0, 30, 60, 90, 120, 150, 180, 210, 240 and 270 mM of NaCl) were arranged in randomized complete block design with three replicates. Regression analysis of data indica...
Seed pretreated with plant growth regulators can improve germination parameters, growth, and yield of crops. Thus, in two greenhouse and field experiments, effects of seed treatment with 0.1 mM salicylic acid (SA), 1µM methyl jasmonate (MJ), 1.5% humic acid (HA), and water (as Control) on germination parameters, seedling growth, and also growth and fruit yield were studied. In the first experim...
Abstract: Sulphur dioxide (SO2) is one of the main air pollutants that can cause imbalance in growth and physiological function of plant in high concentrations. Rhizobium-plant symbiosis can cause increasing in plant resistance to abiotic and biotic stresses in addition to increase growth of plant. In this study, effects of Rhizobium (native and standard strains) on leaf anatomical parameter...
effects of arbuscular mycorrhizal fungus (glomus mossea ca) and plant growth promoting rhizobacteria (pgpr) of bacillus pantea and psedomonas putida were evaluated on growth parameters of osteospermum (osteospermum hybrida ‘passion mix’) under different watering conditions (field capacity, two and one third of field capacity). arbuscular mycorrhizal fungus (amf) and pgpr were applied as single ...
The aim of this study was to examine the effects of replacing fish meal with plant sources on growth performance, immune responses, hematological parameters and disease resistance in rainbow trout. In this study, mean of initial body weight of fish was 15±2 g and the experiment was carried out for a period of 60 days. Four experimental diets were formulated to replace 0, 40, 70 and 100% fish me...
a field experiment was conducted during 2009-2011 at the aligarh muslim university agricultural research farm, india, to evaluate the efficacious nature of some oil-seed cakes such as neem cake and castor cake, a botanical calotropis procera and phosphate solubilizing bacteria (psb) pseudomonas fluorescens singly and in various combinations, on the growth and productivity of trigonella plant. g...
To study the influence of rhizobium inoculation on growth and yield of groundnut (Arachis hypogaea) cultivars, an experiment was conducted at Kurram Agency, Pakistan during 2007. The rhizobium inoculation significantly enhanced the growth and yield parameters of groundnut cultivars. However, the maximum plant height (88.43 cm), number of shoots (19.9 plant), number of leaves (173.27 plant), num...

This paper proposes a non-contact plant growth measurement system using infrared sensors based on the ubiquitous sensor network (USN) technology. The proposed system measures plant growth parameters such as the stem radius of plants using real-time non-contact methods, and generates diameter, cross-sectional area and thickening form of plant stems using this measured data. Non-contact sensors h...
