plant growth promoting bacteria with various mechanisms such as an increase in uptake and availability of nutrients can improve plant growth. in order to evaluate the effects of biofertilizers and vermicompost on quantitative characteristics and essential oil content of vegetative parts of summer savory, a field experiment was conducted during growing season of 2008- 2009 at agriculture researc...

Most arid and semiarid areas are bare greatly infested with intrusive wild species. Buffel grass (Cenchrus ciliaris L.) Sudan (Sorghum sudanense Piper.) the supreme drought-tolerant grasses that commonly grown in dry regions. Besides water, nitrogen (N) is a vital element limiting growth, yield, herbage quality of such since it has key roles physiological biochemical functions plants. Hence, th...

Purpose : Fruit peels waste is one of the accumulate in huge quantity every day. It a serious problem and need to be managed make environment free from pollution. are very rich macro micro nutrients that beneficial for plant growth. By using fruit peel as fertilizer we can reduce load wastes get more benefits than inorganic fertilizer. Research Method The experiment was carried out Completely R...

BF2P4-5 was isolated from the rhizosphere soil of tomato plants, and its potential to promote plant growth investigated in plants. An vitro test revealed that strain could fix nitrogen, solubilize phosphate potassium, synthesize indole acetic acid. The bacterial identified characterized as a kind Pseudarthrobacter chlorophenolicus based on analysis culture characteristics, physiological biochem...

the effect of shoot pruning (2, 3 and 4 branches per plant) and fruit position selection (on main branch vs on main and lateral branches) on yield and qualitative characteristics of two greenhouse grown pepper (capsicum annuum l.) cultivars (torkal and paramo) was studied through a factorial experiment arranged in a completely randomized block design, of three replications. results indicated th...

pistacia atlantica is the most important tree species for the economy of many rural areas in west of iran, but no effort has been made for the genetic improvement of this species. the aim of this investigation was to study the genetic variation and inheritance of early growth traits in p. atlantica. for this purpose, three wild pistachio populations comprising 60 randomly selected adult trees f...

In order to study the effect of nitrogen rate and plant density on morphological traits and essential oil and fruit yield of coriander, a split-plot experiment was carried out in research field of Islamic Azad University, Birjand Branch, Birjand, Iran in 2010 based on a randomized complete block design with three replications. The main plots were nitrogen rates at four levels (0, 40, 80 and 120...

Plant height is a major trait affecting yield potential in rice. Using a large-scale hybrid transcription factor approach, we identified the novel MYB-like transcription factor OsMPH1 (MYB-like gene of Plant Height 1), which is involved in the regulation of plant height in rice. Overexpression of OsMPH1 leads to increases of plant height and grain yield in rice, while knockdown of OsMPH1 leads ...

Crop height not only determines plant resistance to lodging and crowding, but also affects crop architecture, apical dominance, biomass, mechanical harvesting. Plant is determined by the internode elongation, regulated genes involved in gibberellin (GA) brassinosteroid (BR) biosynthesis or related signaling networks. Plants’ genetic inability synthesize respond GAs BRs induce dwarfness. However...
