This is a limiting factor for growing plants from warmer areas in different climatic area where the temperature is less suitable for cultivation The plants response to cold varies from species to species and even within the same plant family. Temperature effects on the hydrolysis rates at pH 3 of pectin samples from different sources, as indicated by values for the entropy and enthalpy of activation for this reaction, were very different from the effect of temperature on cucumber tissue softening at the same pH. Changes in the global climate, notably in regional spatial and temporal temperature patterns (Houghton, Jenkins & Ephraums 1990), are predicted to have important consequences for crop production . 1975 Jan 15;31(1):75-7. In conclusion, changes in temperature have a substantial influence on the uptake and metabolism of cyanide by plants, but cyanide accumulation does not increase with temperature. Heat stress increased accumulation of foliar sucrose and decreased starch accumulation in mature leaves but did not affect glucose. A … The metabolic theory of ecology (MTE) is an extension of Metabolic Scaling Theory and Kleiber's law.It posits that the metabolic rate of organisms is the fundamental biological rate that governs most observed patterns in ecology. Effect of temperature (1000/degrees K) on mass-normalized resting metabolic rate (B 0, in W/g 3/4) for unicells (A), plants (B), multicellular invertebrates (C), fish (D), amphibians (E), reptiles (F), and birds and mammals (G).
