Both sugar and salt are needed for plant growth.
But first a distinction needs to be made between what is meant by "sugar" and "salt". In the home context salt refers to Sodium Chloride (NaCl) or normal table salt; refined and granulated sugar is normally sucrose (a Disaccharide) which is a carbohydrate.
In Biological context:
The results:
Salt
The elements in normal table salt (NaCl - Sodium Chloride) are both used by the plant in its metabolic process, but in very small amounts - normally measured in parts per million (ppm) of concentration. Adding table salt to the soil upsets the osmotic potential of the soil water (as well as the pH)- this prevents water from being drawn into the plant so most plants will wilt and die - even at relatively low levels.
Certain plants are adapted to living in saline soils and have specific mechanisms which enable them to extract water and process high levels of salt. These plants are normally termed halophytes.
Sugar
Sugar can in fact have short term benefits to plant growth, however the long term effects can prove fatal. Accumulation of sugar in the soil provides the ideal breeding environment for bacteria and fungi, some of which can invade and attack the plant.
It's best not to experiment with either on plants you want to keep. Salt added to the ground will render it useless to almost all plants.
If you want to experiment do it with plants in a pot so as not to contaminate your ground.
Sugar water...plain water is not enhanced...sugar and salt water have things in them that give plants a boost with growing.
Fresh water.

Plain Water. Sugar water causes a aciding effect on the plant and will form a white mold.
This is the plain water.
Sugar,sugar helps increase cellulose and help the plant grow faster. Plain water will maintain the status Que.

sugar water. plain water is sort of like nuetral, whereas sugar is FOOD for the mold so they thrive on it and it encourages their growth.:)
Saturated salt water freezes at a lower temp than saturated sugar water, which freezes at a lower temp than plain water. So plain water will freeze first then sugar water then salt water. Thank you QUIRKIE @ answerbag.com
I think that sugar water will freeze faster.
The dissolution of sugar into water doesn't take away the sugar content at all nor does it increase the amount of blood sugar in the body as opposed to plain sugar. Blood sugar is effected by sugar and the addition of water doesn't have anything to do with it.
it is sugar water
No, addition of table salt (NaCl) to water used for watering plants will normally kill the plant.
