Background: The application of polyamines as a plant growth substance with effect on a wide range of plant growth and development processes include cell division, flowering, senescence delay, membrane stability, absorb active radicals and different stress tolerance and polyamines Function as a anti-senescence and anti-stress agents in the plant and on the other hand the competitiveness of their...

in this research, the effect of using vermicompost on growth rate, fertility and characteristics oftomatoes has been studied. four vermicompost: soil mixture were supplied with ratios of 1:1, 1:2, 1:3, and 1:4 and also four different beds were provided. total of 24 small globe tomato plants were tested and in each bed combination, six tomato plants were embedded. rate of growth and yielding of ...

Fruit wastes of apple (Malus pumila), banana (Musa paradisiaca), papaya (Carica papaya), pomegranate (Punica granatum) and sweet orange (Citrus sinesis) @ 20g/plant and the fungal biocontrol agent Paecilomyces lilacinus @ 2g (mycelium+spores)/plant, alone and in combination were evaluated for the management of reniform nematode, Rotylenchulus reniformis infecting chickpea under glasshouse condi...

BACKGROUND Enzymatic degradation of plant biomass requires a complex mixture of many different enzymes. Like most fungi, thermophilic Myceliophthora species therefore have a large set of enzymes targeting different linkages in plant polysaccharides. The majority of these enzymes have not been functionally characterized, and their role in plant biomass degradation is unknown. The biotechnologica...

The presence and composition of soil microbial communities has been shown to have a large impact on plant-plant interactions and consequently plant diversity and composition. The goal of the present study was to evaluate impact of arbuscular mycorrhizal fungi (AMF) and nitrogen-fixing bacteria, which constitutes an essential link between the soil and the plant's roots. A greenhouse pot experime...

abstract in order to study salt stress, calcium and potassium effects and type of application on sorghum plant, a field experiment was arranged in randomized complete block in split plot design at the research field of center of excellence for special crops, ferdowsi university of mashhad at 2008. experimental treatments were included two levels of salinity (5 and 10 ds.m-1) as main plots and f...

abstract plant- growth promoting rhizobacteria enhance plant growth and yield directly and or indirectly. a factorial experiment was conducted in greenhouse to determine the efficacy of four strains of fluorescent pseudomonas on wheat yield and yield component under saline conditions. the experiment was carried out with the following treatments (non –inoculation control and inoculation with p.f...
