to study the effects of biofertilizers on physiological and morphological characteristics, as well on essential oil content in dragonhead (dracocephalum moldavica), an experiment was conducted at tarbiat modares university in 2009. the studied factors were: vermicompost (0, 15, 30% v/pot), azotobacter (inoculated and non-inoculated), and phosphatic biofertilizer (inoculated and non-inoculated)....

abstract paclobutrazol is one of the most important triazolic compounds which are used as growth retardants in some crops. in this study, the effect of application methods and concentration of paclobutrazol on plant height of tuberose and possibility of pot production was investigated. in the first experiment, tuberose bulbs were soaked in 0, 25, 50, 75 and 100 mg.l-1 paclobutrazol for 10, 20 a...

the plant promoting bacteria as biological fertilizers play an important role in increasing productivity and improving plant growth in stress condition. in order to evaluate the ability of plant promoting bacteria rhizobacteria on germination and growth of corn under salinity conditions, a pot experiment was conducted in factorial based on randomized complete block design with three replication...

A pot experiment was conducted to evaluate the effect of salinity on growth and heavy metal uptake by maize (Zea mays) plant. The results study show that NaCl NaCl+CaCl2 treatments decreased plant (plant height, shoot weight root weight) significantly. proportion viable roots fresh declined with time. In contrast, enhanced length. increased accumulation Cd, Zn Cu in considerably both root.

Abstract Plant invasion is one of the most serious threats to ecosystems worldwide. When invasive plants with ability clonal growth invading or colonizing in new habitat, their interconnected ramets may suffer from heterogeneous light. Effects integration on allelopathy are poorly understood under light conditions. To investigate effects plant Wedelia trilobata conditions, a pot experiment was ...

plant growth promoting rhizobacteria and arbuscular mycorrhizal fungi can inhanced plant growth by increasing nutrient uptake. in order to investigate the effect of pgpr and amf on some morphological parameters, macro (nitrogen, phosphorus, potassium, calcium and magnesium) and micro (iron, zinc and copper) nutrients uptake, percentage of root colonization and some morphological factors of pepp...

Descriptions of nutritional deficiencies in literature are mostly based on agricultural crops. As every plant variety reacts very individually on deficiency or excess of nutrients, there is still a large lack of information on horticultural products. For this reason many vegetable and pot plant varieties have been tested on symptoms of nutritional deficiencies by selective fertilisation at the ...
