Question: Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may result from: drought conditions, where the soil moisture drops below conditions most favorable for plant functioning; the temperature falls to the point where the plants vascular system can not function. high salinity, which causes water to diffuse from the plant cells and induce shrinkage; saturated soil conditions, where roots are unable to obtain sufficient oxygen for cellular respiration, and so are unable to transport water into the plant; or bacteria or fungi that clog the plant's vascular system. Wilting diminishes the plant's ability to transpire and grow. Permanent wilting leads to plant death. Symptoms of wilting and blights resemble one another. Jim had a small veggie garden that he planted every year. His brother Rob had a similar patch, and he was also a gardener. The plants in Jim's garden started wilting at some point and he found out that his soil had high salinity and some harmful bacteria that wiled the plants indirectly. Rob's plant were ok, because he adjusted the soil's ph with sweet lime. Which garden soil had more bacteria and fungi problems?
Answer:
Jim's
