Salt water can have a harmful effect on plant growth by hindering the plant's ability to absorb water due to the unfavorable osmotic pressure induced in the root system. This is referred to as the water-deficit effect of salinity and results in the plant condition known as physiological drought. An excessive amount of salt entering the plant through the transpiration stream will also reduce growth by injuring leaf cells in a condition referred to as the ion-excess effect of salinity.Know More
Overall, plants can be injured when their foliage or roots are exposed to water containing salt. Water molecules are held tightly by salt ions. This makes it difficult for the plant to absorb water. When water containing salt enters the soil, the sodium ions also attach to soil particles, causing the ground to compact and become dense, reducing both drainage and aeration. The chloride component can mobilize heavy metals present in the soil and reduce plant vigor and growth.
Excessive amounts of sodium and chloride components in the root zone can cause the plant to suffer from phosphorous and potassium deficiency. Although plants require these mineral nutrients, the root system may bypass them in favor of absorbing the salt-derived ions. Chloride ions can also accumulate in toxic levels within plants and become concentrated in the plant's actively-growing tissues. This condition can cause twig die-back and leaf burn.
Because plants do not have the means to eliminate or excrete excessive salt from their tissues as animals can, their only defense is to remove the salt through dead leaves and needles. Plants that do not shed their leaves on a yearly basis, such as conifers, are particularly vulnerable to salt accumulations.Learn more about Botany
According to Gardening Know How, water can affect plant growth both positively and negatively. When plants receive the right type and correct amount of water, they flourish. However, too much water can result in root rot. If there is not enough water, the plant cannot get the nutrients it needs to sustain life. Too much or too little water often results in the death of the plant.Full Answer >
Plant growth is inhibited by very hot or cold water, but slightly improved by warmer water of room temperature in many varieties of plant. Low temperatures in general also inhibit plant growth, as does the amount of temperature differentiation between night and day.Full Answer >
Plant growth can be affected by different types of water and the main reason for this is the level of salt in the water. Most plants thrive better when watered with water that has low levels of salt.Full Answer >
Plants are generally unaffected by light winds, but high winds can stunt plant growth. This problem can be avoided by frequent watering, using good fertilizer to encourage healthy roots and creating wind breaks.Full Answer >
