Abstract
Response in growth of maize to temperature was studied under controlled conditions. The growth of plants was measured in terms of : I. Growth characters A. Stem, (1) surface area (πdh) (2) volume (πr2/h) B. Leaves, (1) area, (2) dry weight II. Growth attributes or physiological components of growth A. Net assimilation rate (NAR) B. Relative growth rate (RGR), (1) dry weight (R), (2) leaf area (RL) C. α coefficient (R/RL) III. Morphological components of growth A. Leaf area ratio (LAR) : leaf area/total dry weight B. Leaf weight ratio (LWR) : leaf weight/plant weight C. Specific leaf area (SLA) : leaf area/leaf weight = 1/leaf thickness. The response was measured in terms of these characters and critically analysed in relation to temperature and age of plants.
