What are the factors of plant growth?
The primary factors that affect plant growth include: water, temperature, light, and nutrients. These four elements affect growth hormones in the plant, causing it to grow more quickly or more slowly.
What are the physical and chemical requirements for plant growth?
Plants obtain the three most abundant nutrients, carbon (C), hydrogen (H) and oxygen (O), from water and the air. The other elements, including nitrogen, need to be supplied into the soil by soil amendments, such as fertilizers and lime.
What are the physiographic factors of plant growth?
The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on vegetation and direction of slopes (3) Biotic factors which include …
What is the growth of a plant?
Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth, and is the result of cell division in the shoot apical meristem.
What are the edaphic factors affecting plant growth?
Edaphic factors include excessive soil moisture, drought, soil acidity, P deficiency, excess mineral N and deficiency of Ca, MO, CO and B.
What are some variables that affect plant growth?
The soil pH can also influence plant growth by its effect on activity of beneficial microorganisms Bacteria that decompose soil organic matter are hindered in strong acid soils. This prevents organic matter from breaking down, resulting in an accumulation of organic matter and the tie up of nutrients,…
What are the factors that influence growth of plants?
Climate. Climate usually involves average rainfall,temperature,and wind patterns.
What are biotic and abiotic factors which affect plant growth?
growth, development and productivity. The abiotic factors that affect plant growth and development include topography, soil, and climatic factors . They are the nonliving components of the environment which, along with the biotic or living factors, determine the extent in which the genetically-dictated characters are expressed in the plant.
What factors determine how a plant grows?
Plants Growth Process: What Makes them Grow? Air. Air is a basic necessity for plants’ growth and survival. Water. Water is also a raw material for photosynthesis process, with the help of which glucose is produced in the presence of sunlight. Light. When we say photosynthesis, it means synthesis of chemical compounds in the presence of light. Nutrients. Soil.
