The most obvious are the effects of heat on photosynthesis, in which plants use carbon dioxide to produce oxygen, and respiration, an opposite process in which plants use oxygen to … The purpose of this project is to determine how temperature affects plant growth. Also: The effect of soil temperature in seed germination : Introduction: For farmers and growers it is important to know the best conditions for the growth of their products. How does the temperature affect the plant growth?
Germination of Seeds: The germination of the different seeds is greatly influenced by the variation in soil temperature. Soil temperature affects the speed of plant growth and soil processes. Light, Temperature and Humidity. 45 Water uptake This is due to the increased viscosity and decreased absorption rate of water at low temperature Toselli et al.
How Soil Temperature Affects Germination and Growth Life is fragile, so seeds are fussy. The temperature in a soil will determine the speed of chemical and biological activity. 44 Decreased water uptake reduces the rate of photosynthesis.
Soil temperature is influenced by: climate, season, aspect, water levels, soil colour, plant cover and soil depth. If the temperature is too low, the seed fails to germinate or germinate at a slow rate. In the past, just by experience most farmers and growers learned what is the best season for planting certain plants. Light energy is used in photosynthesis, the plant’s most basic metabolic process. Light is an essential factor in maintaining plants. After reading this article you will learn about the influence of soil temperature on plant growth and nutrition. High temperatures affect plant growth in numerous ways. How Does Temperature Affect Plant Growth? They are happy to put forth the extraordinary effort needed to produce a plant, providing of course, that the conditions are just right. The results of such research can help a grower to identify the best temperature for optimizing the growth of any specific plant. 1. For Question 2: The purpose of this project is to see in which soil temperature (32°c, 18°c or 5°c) more seeds will sprout. The rate of growth and length of time a plant remains active is dependent on the amount of light it receives. Soil temperature has a great effect on plant growth by influencing water and nutrient uptake Toselli et al., 44 root and shoots growth Weih et al.
