Stunted growth not caused by infection may be due to a wide variety of environmental factors. Environmental factors that affect plant growth include light, temperature, water, humidity and nutrition. There may be water imbalance, poor planting practices, poor nutrition, or physical injury to the plant.
Peach leaf curl is a plant disease characterized by distortion and coloration of leaves and is caused by the fungus Taphrina deformans, [1] which infects peach, nectarine, and almond trees. T. deformans is found in the United States , Europe , Asia , Africa , Australia , and New Zealand . [ 2 ]
Poor plant uptake of a nutrient from the soil (or other growing medium) may be due to an absolute shortage of that element in the growing medium, or because that element is present in a form that is not available to the plant. [6] The latter can be caused by incorrect pH, shortage of water, poor root growth or an excess of another nutrient. [6]
Experiments on arabidopsis show that the plant detects the change in temperature, rather than the absolute temperature. [2] The rate of temperature drop is directly connected to the magnitude of calcium influx, from the space between cells, into the cell. Calcium channels in the cell membrane detect the temperature drop, and promotes expression ...
Plant perception is the ability of plants to sense and respond to the environment by adjusting their morphology and physiology. [1] Botanical research has revealed that plants are capable of reacting to a broad range of stimuli, including chemicals, gravity, light, moisture, infections, temperature, oxygen and carbon dioxide concentrations, parasite infestation, disease, physical disruption ...
Plant stress research looks at the response of plants to limitations and excesses of the main abiotic factors (light, temperature, water and nutrients), and of other stress factors that are important in particular situations (e.g. pests, pathogens, or pollutants). Plant stress measurement usually focuses on taking measurements from living plants.
Wheat is another major crop that is affected by drought: lack of water affects the plant development, and can wither the leaves. [21] [22] Maize crops can be affected by high temperature and drought, leading to the loss of maize crops due to poor plant development. [21] Soybean is a major source of protein, and its production is also affected ...
Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Although there are many kinds of biotic stress, the majority of plant diseases are caused by fungi. [ 4 ]
