| What does the term 'bronzing' describe in plant tissues? | development of bronze or copper colour on the tissue | Some common terms are, bronzing (development of bronze or copper colour on the tissue), chlorosis (loss of chlorophyll resulting in loss of green colour leading to pale yellow tissues), decline (onset of general weakness as indicated by loss of vigour, poor growth and low productivity), die-back (collapse of the growing tip affecting the younger leaves), firing (burning of tissue accompanied with dark brown or reddish brown colour), lesion (a localised wound of the leaf/stem tissue accompanied with loss of normal colour), necrosis (death of tissue), scorching (burning of the tissue accompanied with light brown colour resulting from faulty spray, salt injury etc.) Some crops are more sensitive than others to the deficiency of a micronutrient and it can be inferred that the critical concentration of a nutrient is not same for all the crops. | 33 | definition | 1.000 | Some common terms are, bronzing (development of bronze or copper colour on the tissue), chlorosis (loss of chlorophyll resulting in loss of green colour leading to pale yellow tissues), decline (onset of general weakness as indicated by loss of vigour, poor growth and low productivity), die-back (collapse of the growing tip affecting the younger leaves), firing (burning of tissue accompanied with dark brown or reddish brown colour), lesion (a localised wound of the leaf/stem tissue accompanied with loss of normal colour), necrosis (death of tissue), scorching (burning of the tissue | 1 | page=1,block=2 | 0.700 | valid |

| Why should terms like low, moderate, or high be used with caution in describing crop tolerance to nutrient deficiencies? | terms such as low, moderate or high are very relative | The susceptibility or tolerance rating of crops to nutrient deficiencies shows considerable variation due to wider hereditary variability within a crop species. Further, terms such as low, moderate or high are very relative and should be used with caution. Diagnostic plant symptoms of nutrient element insufficiencies When a nutrient element insufficiency (deficiency and/or toxicity) occurs, visual symptoms may or may not appear, although normal plant development will be slowed. When visual symptoms do occur, such symptoms can frequently be used to identify the source of the insufficiency. | 170 | relationship | 0.970 | Further, terms such as low, moderate or high are very relative and should be used with caution. | 1 | page=1,block=2 | 0.700 | valid |

| What can an excessive amount of potassium in a plant lead to? | either a magnesium (Mg) and/or calcium (Ca) deficiency | Toxicity symptoms Visual symptoms of toxicity may not always be the direct effect of the element in excess on the plant, but the effect of the excess element on one or more other elements. an excessive level of potassium (K) in the plant can result in either a magnesium (Mg) and/or calcium (Ca) deficiency, excess phosphorus (P) can result in a zinc (Zn) deficiency, and excess Zn in an iron (Fe) deficiency. These effects would compare to elements, such as boron (B), chlorine (Cl), copper (Cu), and manganese (Mn), which create visual symptoms that are the direct effect of an excess of that element present in the plant. Some elements, such as aluminum (Al) and copper (Cu) can affect plant growth and development due to their toxic effect on root development and function. | 252 | relationship | 0.970 | an excessive level of potassium (K) in the plant can result in either a magnesium (Mg) and/or calcium (Ca) deficiency, excess phosphorus (P) can result in a zinc (Zn) deficiency, and excess Zn in an iron (Fe) deficiency. | 2 | page=2,block=0 | 0.700 | valid |

| What does a high nitrogen level in plants increase sensitivity to? | moisture stress and easily susceptible to insect and disease infestations | particularly the use of plant analyses and / or tissue tests if the cause for visual disorders is to be correctly identified. Other effects A nutrient element insufficiency (deficiency or excess) can make the plant sensitive to climatic stress, and/or be easily subjected to insect and disease infestations. A high nitrogen (N) level in the plant can make the plant sensitive to moisture stress and easily susceptible to insect and disease infestations. If ammonium-nitrogen (NH4-N) is the primary source of nitrogen (N), symptoms of NH4 toxicity, fruit disorders, and the decay of conductive tissues may occur. Some fungus diseases are more likely to occur on plants that are marginally deficient in a particular element, an example being the occurrence of powdery mildew on leaves of greenhouse-grown cucumber when magnesium (Mg) is not fully sufficient. | 379 | relationship | 0.970 | A high nitrogen (N) level in the plant can make the plant sensitive to moisture stress and easily susceptible to insect and disease infestations. | 3 | page=3,block=0 | 0.700 | |
| What are the effects of excessive magnesium in plants? | Results in a cation imbalance showing signs of either a Ca or K deficiency. | Excess Plants may exhibit typical Mg deficiency symptoms, and when in high excess, K deficiency may also occur. Magnesium (Mg) Deficiency Older leaves will be yellow in colour with interveinal chlorosis (yellowing between the veins) symptoms. Plant growth will be slow and some plants may be easily infested by disease. Excess Results in a cation imbalance showing signs of either a Ca or K deficiency. Sulfur (S) Deficiency A general overall light green colour of the entire plant with the older leaves being light green to yellow in colour as the deficiency intensifies. Excess A premature senescence of leaves may occur. Boron (B) Deficiency Abnormal development of the growing points (meristematic tissue) with the apical growing points eventually becoming stunted and dying. Flowers and fruits will abort. For some grain and fruit crops, yield and quality is significantly reduced. | 327 | relationship | 0.970 | Excess Results in a cation imbalance showing signs of either a Ca or K deficiency. Sulfur (S) Deficiency A general overall light green colour of the entire plant with the older leaves being light green to yellow in colour as the deficiency intensifies. | 4 |
