WILTING.
Wilting is a term indicating a disease affecting tomato, aster, stock, zinnia and many other plants. TJie main function of the leaves is to absorb carbonic acid gas from the air, whilst that of the root hairs is to absorb water, together with nitrate, phosphoric acid and potash which it dissolves, out of the soil. These different gases and
solutions are assimilated or digested by the plant, and its structure thus built up. Surplus water is exuded by the leaves, and when this transpiration is checked the plant “ wilts,” thus indicating that the plant is losing more water than it is absorbing. If a “ wilted ” plant be examined at the ground line, it will be found to have developed rot at the stem and that the supply of root energy has been effectually cut off as a result of bacterial action for which there is no cure at present.
