Transpiration rate factors
leaf temperatures; so that the transpiration rate of a leaf might be estimated by comparing its temperature with that of other leaves or with the air temperature. While investigating the relation of hairy leaf coverings to the resistance of leaves to water loss,* a number of experiments were performed which show the Many environmental factors influence the rate at >rhich transni ration nrocsede. Solar radiation, the temoerature of the air surrounding the leaf, relative humidity, Measuring rates of transpiration using a potometer. Using a potometer, one can directly measure the rate of uptake of water in plants under different atmospheric Mar 14, 2018 Plant transpiration rates are affected by biophysical factors, such as air temperature, vapour pressure deficits and net radiation, and by plant Opening and Closing of Stomata by Abscisic Acid. 9.2.9 Explain how the abiotic factors light, temperature, wind and humidity, affect the rate of transpiration in a light or dark? 2. Which condition would result in the higher rate of transpiration: humid environment or dry environment?
From the rates of transpiration of fruit (Ffruit) and pedicels (Fpedicel), the The effects of various factors on transpiration rate were accounted for by their effects
The light increased the rate of transpiration for 5/9 of the plants. Did any of the environmental factors (heat, light, or wind) increase the transpiration rate more May 24, 2019 Other factors influencing water needs need to be considered in addition to temperature, humidity, and transpiration rates. The water needs of Water is the most limiting abiotic (non-living) factor to plant growth and productivity, plants directly into the atmosphere, a process referred to as transpiration. However, when stomata open, water is lost to the atmosphere at a prolific rate Mar 15, 2019 Transpiration can occur at high rates and, therefore, water must effectively be replaced through root uptake and transported through vascular

Environmental factors that affect the rate of transpiration. 1. Light Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates Learners will need to understand the factors that affect the transpiration rate such as temperature, light intensity, wind and humidity. Simple experiments can be
Plant Factors Affecting the Rate of Transpiration 1. Root-shoot ratio . All other plant factors and the outside environment being equally favorable, 2. Leaf area and number of stomata . A plant with greater total leaf area will transpire more water 3. Leaf structure . Several structural

Temperature: Transpiration rates go up as the temperature goes up, especially during the growing season, when the air is warmer due to stronger sunlight and warmer air masses. Higher temperatures cause the plant cells which control the openings (stoma) where water is released to the atmosphere to open, whereas colder temperatures cause the openings to close. Factors Affecting the Rate of Transpiration. There is a close inter-relationship between transpiration and leaf structure. The rate at which transpiration occurs refers to the amount of water lost by plants over a given time period. Plants regulate the rate of transpiration by opening and closing of stomata (see figure below).
Factors Affecting the Rate of Transpiration Environmental factors such as intensity of light, temperature, atmospheric humidity, wind velocity, availability of soil water, etc., affect the rate of transpiration. Plant Factors Affecting the Rate of Transpiration 1. Root-shoot ratio . All other plant factors and the outside environment being equally favorable, 2. Leaf area and number of stomata . A plant with greater total leaf area will transpire more water 3. Leaf structure . Several structural Transpiration - Factors Affecting Rates of Transpiration PLANT PARAMETERS – These plant parameters help plants control rates of transpiration by serving as forms of resistance to water movement out of the plant. Environmental factors that affect the rate of transpiration. 1. Light. Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata 2. Temperature. Plants transpire more rapidly at higher temperatures because water evaporates
