A PROTECTORY ROLE OF SALICYLIC ACID TO ENVIRONMENTAL STRESS

The growth of plants is very

strongly restricted and even modified by the environments the plants experiences.

Indeed plants are product of two major determinants, i.e. first their

replication or genetic capabilities and second their environments. By breeding,

selection, and choice we can modify genetic capability, however, our ability to

modify environment is much less successful. Indeed naturally imposed

environmental stresses are experienced by crops in virtually all ecosystems. It

has been documented that environmental stresses such as extreme temperatures

(heat and cold) are major restrains worldwide against regularly obtaining

maximum plant production. In nearly all or Balkan countries plants commonly

experience the strong influence of extreme temperatures. The severity of those

stresses vary from short-terms, to the entire growing season, furthermore the

severity is not predictable.<o:p></o:p>
