Temperature plays a vital role in life processes
and crop production. Physical and chemical processes
within plants are temperature dependent; these
processes in turn control biological reactions in crop
plants. Temperature also plays a significant role in
some aspects of crop physiological cycles: the diffusion
rate of gases and liquids changes with temperature;
the solubility of substances is temperature dependent;
rapid progress occurs as a result of temperature
increases; and the equilibrium and stability of
various systems and compounds (including enzymes)
is a function of temperature.
Air temperature at the screen level is one of the
most important variables affecting crop production in
temperate Kashmir. Most crop plants are injured or
killed by low night temperatures, especially those
plants that are growing rapidly or flowering. Low
temperature in combination with wet soil may result
in the accumulation of harmful products in plant cells
while low temperature coupled with water shortage
results in cold drought.
