Effects Of Humidity On Plants. Most palm types Ficus Bamboo and Schefflera and others thrive in higher humidity. In order to estimate the effects of global warming on plants the effects of carbon dioxide concentration 500 ppm or 1000 ppm CO2 andor relative humidity 37 or 79 RH on the growth and the transpiration of several C3 plants and a C4 plant corn were investigated by using artificially-lighted growth cabinets. Water use efficiency increased as humidity increased. Plants use stomata to transpire or breathe.
The dry weight growths of all species especially C3 plants were accelerated by an. When the humidity level is too high the plants will have a difficult time producing or transporting the food. For example because humidity reduces ambient oxygen concentrations dry air is typically 209 oxygen but at 100 relative humidity the air is 204 oxygen flue gas fans must intake air at a. In this video I explain the transpiration pro. Most other non-succulent plants benefit from higher humidity because it reduces transpiration leaf tipping and can discourage mite pests. The excess of humidity also reduces perspiration and the absorption of nutrients.
High humidity can often have a negative effect on the capacity of chemical plants and refineries that use furnaces as part of a certain processes eg steam reforming wet sulfuric acid processes.
This is especially true if soil moisture is inadequate and wilting occurs. The human body depends on perspiration to get rid of excessive heat. The excess of humidity also reduces perspiration and the absorption of nutrients. Increasing the relative humidity from 70 to 90 per cent at 20 C increased dry weight by 2030 per cent and sometimes by considerably more. The dry weight increased significantly by increasing RH from the lowest to the highest level in Begonia hiemalis 47 Saintpaulia ionantha 1736 Euphorbia pulcherrima 31 Chrysanthemum. The fresh weight of all parts of the plant increased with increasing humidity.
