Some of the factors affecting plant growth include availability of nutrients, water, temperature, light, air pollution, gases and plant genetics. It is important to understand how these factors affect plant growth and development. Keywords: soil temperature, heat, organic matter decomposition, plant growth, radiant energy

Consequently, lower root growth at high soil temperature leads to impaired water and nutrient uptake in plants (Li et al., 2016). All crops practically slow down their growth below the temperature of about 9 0 C and above the temperature of about 50 0 C. The biological processes for nutrient transformation and nutrient availability are controlled by soil temperature and soil moisture. Soil temperature alters the rate of organic matter decomposition and mineralization of different organic materials. Author information: (1)Soil Science Unit, FAO/IAEA Agriculture and Biotechnology Laboratory, Seibersdorf, Austria. Temperature is one of four main functions controlling plant growth. The effects of temperature on the rate and extent of root colonization are complex, the responses varying with both fungus and plant (Smith and Read, 2008). Provides a medium for plant growth 1; Our focus will be on the fifth function. How does cold storage affect the germination of seeds? If the temperature reaches a certain temperature such as -7 degrees grass will freeze, but not die. r.hood@iaea.org The effect of soil temperature and moisture on plant growth and mineralisation of organic residues was investigated using 15N-labelled soybean residues and temperature-controlled tanks in the glasshouse. In this role, soil provides structural stability for plants and retains and relinquishes water and the nutrients necessary for plant growth. The very common feature observed when a plant is exposed to high soil temperature is a reduction in root/shoot ratio (Arai-Sanoh et al., 2010). Factors you can control include the type of seeds, the length of storage, the temperature of storage, and other variables, such as light and humidity. Yes, temperature does have an affect on the growth of a plant. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. Soil temperature and plant growth Soil micro-organisms show maximum growth and activity at optimum soil temperature range. Factors which can affect Soil temperature. What effects does an allelochemical have on a plant? Temperature is a primary factor affecting the rate of plant development. The ability to form mycorrhizas at low temperatures may be related to adaptation of some fungi … A change of temperature alters metabolic activity and even affects aquatic ecosystems. Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. There are many factors which affect soil temperature and determine how quickly it rises and falls. If the temperature reaches a certain temperature such as -7 degrees grass will freeze, but not die. What conditions affect the ripening of fruit? Yes, temperature does have an affect on the growth of a plant. What Factors Affect Plant Growth? Water temperature affects plants in many ways. In addition to temperature; water, nutrients, and light control commencement of growth, rate of growth, and cessation of growth. It also affects soil water content, its conductivity and the processes that takes place in the soil which are necessary for plant growth. Further, high temperature influences the nutrient cycle (Pilbeam, 2015). From houseplants to aquatic plants, water temperature plays a part in growth and development. These issues can either enable a plant to develop rapidly or much slower.
