For optimum growth of the plant, the existence of approximately equal amount of macro and micro-pores which influence aeration, permeability, drainage and water retention favorably. Plant growth regulators are usually produced in the growing tissue. The light and the temperature changes that come in the spring will stimulate plants to break dormancy and start to grow new leaves. ADVERTISEMENTS: Growth in plants depends on various internal and external factors. From season to season light varies in intensity. But, this is a simplistic view, and in reality there are more direct and indirect factors to … Read more. Like humans, different plants need a specific set of nutrients to stay healthy. Some seasonal plants won’t grow unless they have the right lighting conditions to stimulate their dormancy. Heredity is the transmission of physical characteristics from parents to children through their genes. Plant growth is faster during warmer periods and will slow down or become dormant in a cooler period. Other plants will require a particular lighting spectrum to ensure that they receive just the right amount of nutrients. Different species of plants will require a unique mixture of the four factors mentioned above. All in all, plants need 17 nutrients to survive, with the first three coming from air and water. Sunlight that is available during the summer months will encourage fruiting and flowering. Diseases and conditions such as heart disease, diabetes, obesity, etc., can also be passed through genes, thereby affecting the growth and development of the chil… Although we learn from school that plants need water, sunlight and soil, the more accurate set of growth factors are light, water, nutrients and temperature. Plants will slow down or speed up their growth rate based on the temperature. During the fall months when the light starts to change again, many plants will begin shedding their leaves. The genetic factor is also called internal factor because the basis of plant expression (the gene) is located within the cell. Radiant Energy: Radiant energy is a significant factor in plant growth and development. For this reason, plants have adapted to different types of light. This resource pack enables teachers to highlight and explain the main reasons why plants grow. Growing your plant will require you to have a better understanding of its four growth factors. As mentioned above, different species of plants will have to require varying watering conditions. The other nutrients that the plant needs are found in the soil. For example, blossom end rot occurs on tomatoes that don’t receive enough calcium. A warmer temperature will actually trigger a chemical reaction inside the cells of a plant and this will speed up respiration, transpiration, and the photosynthesis process. Make sure that you rotate your crops regularly and that you add compost and manure to your soil at least once or twice a year to provide your plants with the nutrients they need in order to survive. However, the environment’s climate plays an essential role in a plant’s survival, regardless of its age. 4 DIY Fertiliser Ideas You Can Do at Home – Our Guide, Our Guide to Plant Biostimulants & Their Benefits to Agricultural Farming. ...
