RESPIRATORY COST OF PLANT-GROWTH UNDER CONDITIONS OF SALINITY

The present review examines means and methods of estimating energy exp editures in plants under salinity stress. Possible items of additional energy expenditures in plants under conditions of salinity are discus sed in the paper. Data of ours are cited indicating differences of res piratory cost in growth of haloglycophytes and hyperhalophytes. On the basis of published data and our own determinations, it is concluded t hat a large role in the high tolerance of halophytes to salinity is pl ayed not only by cellular mechanisms, but also by strict synchronizati on of these processes with transition of the cells of all organs from growth to maturity. It is stressed that salt tolerance is a property o f the whole plant organism.
