Environmental Factors Affecting Plant Growth. Plant Growth, development, and distribution are highly influenced by the environment. Any limitation over the availability of ideal environmental factors will put a hindrance upon the growth of the plant and its distribution.
It is seen that plant problem are mainly caused by environmental stress. The absence of an adequate amount of water could impact the growth of a plant. Such a situation can make a complete ruin of a tree. It weakens a plant and makes it more susceptible to attack from insects.
Environmental factors affecting plant growth and development
Environmental factors affecting plant growth and development include light, temperature, water, humidity, and nutrition. At the time of nurturing a tree, it is important to know how these factors could affect the growth and development of a plant. Knowledge about environmental factors helps the owner promotes proper growth.
The various factors affecting plant growth and development can also be classified into external and internal aspects. Of the External factors, light is most important. It regulates the process of photosynthesis. Changes in day length help in regulating the phonological development of rangeland plants. It is important as a physiological process within a plant and the process is carried during daytime only. With the smooth conducting of physiological processes, flowering and other live-related functioning are initiated properly within a plant.
Light intensity has a direct influence on the manufacture of plant food, stem lengthening, and leaf color. Plants like geranium, if grown in the low light condition it will tend to be spindly. The leaves will appear light green.
If the growth takes place in brighter light, the branch distribution would be better and possess larger, dark green leaves.
Plants grown domestically can also be classified according to their light needs, viz., high, medium and low light requirements. The strength of light a plant receives at the indoors depends upon the nearness of the light source to the plant. The direction in which the windows are placed affects the intensity of natural sunlight that plants receive. Lights coming from the direction of the south have the highest intensity, those having eastern and western exposures receive about 60 percent of the intensity of southern exposures, and exposures arrive from the north will receive 20 percent of southern exposure. It implies that the southern exposure is the warmest, eastern and western are less warm and a northern exposure is the coolest.
The intensity of light for plants within a premise is also influenced by factors like the presence of curtains, trees outside the window, weather, the season of the year, shade from other buildings and the cleanliness of the window.
The presence of reflective surfaces inside the home or office will help increase the intensity of light available to plants. Dark surfaces will decrease light intensity.
Role of Temperature in Plant Growth
Plants grown in the houses tolerate normal temperature fluctuations. As is commonly experienced, foliage house
Plants grown in the houses tolerate normal temperature fluctuations. As is commonly experienced, foliage house plants make their best growth when treated within a range of 70 and 80 degrees Fahrenheit during the day. The night temperature ranges between 60 and 68 degrees.
Therefore, such house plants prefer the same daytime range even though they grow best at nighttime temperatures, i.e. ranging between 55 and 60 degrees Fahrenheit. The lower night temperature induces physiological recovery from moisture loss, intensifies flower color, and helps the plants survive for a longer period.
Marked fluctuation in temperatures may cause plant failures, and the growth process may come to a standstill. It may also cause spindly appearance and foliage damage or drop. A cooler temperature at night is more desirable for plant growth than higher temperatures. Therefore, the experts recommend keeping the night temperature 10 to 15 degrees lower than the day temperature.
How does humidity affect plant growth
Humidity has an integral role in the growth of plants. It is a measurement of the percentage of the moisture in the air that has made it saturated. Considering its impetus as one of the top environmental factors affecting tree growth, arrangements are made to offer certain humidity in the area where seedling is planted.
Humidity can increase by various processes. Attaching a humidifier to the heating or ventilating system is one of these.
You can also place gravel trays under the flower pots or containers. In such trays, an even moisture level is maintained. It increases relative humidity within the vicinity of the containers.
Another way to raise humidity is to group plants close together. Spray a fine mist on the foliage though there is a question about its effectiveness in changing the humidity in the environment completely. It is better to carry out this process in the early part of the day; it helps the plants become dry by night, which is recommended.
Why water is essential to plants growth
Of all the external factors affecting plant growth, water has more important roles to play in the proper distribution of plants. However, it is important to understand how to water your plants. Not all plants need the same amounts of water in the same interval.
The most relevant confusion in this regard is the frequency at which the watering process should be conducted. Finding a proper answer to such a query is difficult as different types of plants consume various amounts of water.
The cause of watering in plants is influenced by the nature of the soil and other environmental conditions. Experts opine against the application of water at the time of drying soil crust.
Roots of house, plants rest in the bottom two-thirds of the pot. Experts recommend not to water until the soil starts to dry out. It is best done by feeling the place with soil. Place index finger in about 2 inches into the soil serves the best. Do not start watering if the soil feels damp. Plants don’t like too much stagnant water. Water only when the soil is dry.
If the pot is a smaller one, a measurement can be carried at the depth of 1 inch. You can water the pot until water runs out of the bottom.
The process will serve two purposes. In the first instance, it washes out all the excess salts Again, it ensures that the best parts at the bottom of the pot, where most of the roots have, will get enough water for survival.
You will have to wait till the water dries at the 2-inch depth before pouring more water at the base of trees.
While considering the effect of the environment on plant growth, one must consider the soil acidity. The extent of acidity in the soil influences the availability of nutrients by a plant. While putting an eye on the availability of other environmental factors, the planter must know about the beneficial and toxic minerals for plants. While beneficial elements like Calcium, Magnesium, Phosphorus, and Potassium promote the growth of a plant, toxic elements like Alumina, Molybdenum or Zinc cause damage to the plants.
