Plant Growth-promoting Rhizobacteria: Potential Green Alternative for Plant Productivity
Use of plant growth promoting rhizobacteria (PGPR) for the benefits of agriculture is gaining worldwide importance and acceptance and appears to be the trend for the future. PGPR are bioresources which may be viewed as a novel and potential tool for providing substantial benefits to the agriculture. These beneficial, free-living bacteria enhance emergence, colonize roots, stimulate growth and e...
متن کاملNitrate: nutrient and signal for plant growth.
The mineral nutrient needed in greatest abundance by plants is nitrogen. Plants, however, must compete for nitrogen in the soil with abiotic and biotic processes such as erosion, leaching, and microbial consumption. Soil nitrogen is also lost when crops are harvested and plant material is removed from the soil. To be competitive, plants have evolved several mechanisms to acquire nitrogen at low...
متن کاملUsing SNPs for transplanting of cotton seedlings to increase plant growth and yield
Straw nursery pots (SNPs), which utilize agricultural residues such as wheatstraw and corn stalks as raw materials, can be widely used in the transplantingof seedlings of crops, vegetables, flowers and trees. Plastic nursery pots (PNPs)and direct sowing (DS) were used as controls in evaluating the effects of SNPson plant growth, dry matter partitioning, yields and economic benefits oftransplant...
متن کاملPlant growth and cultivation.
There is a variety of methods used for growing plants indoor for laboratory research. In most cases plant research requires germination and growth of plants. Often, people have adapted plant cultivation protocols to the conditions and materials at hand in their own laboratory and growth facilities. Here I will provide a guide for growing some of the most frequently used plant species for resear...
متن کاملPlant Phototropic Growth
Plants are photoautotrophic sessile organisms that use environmental cues to optimize multiple facets of growth and development. A classic example is phototropism - in shoots this is typically positive, leading to growth towards the light, while roots frequently show negative phototropism triggering growth away from the light. Shoot phototropism optimizes light capture of leaves in low light en...
