摘要

The use of grated plants increases uniformity and anticipate the yield. Rootstocks regulate photosynthetic and water relations of the plant and any disruptions of their metabolism may affect the plant vigor. This work aimed to compare resistance levels of dwarf cashew tree rootstocks CCP06 and CCP09, and grafted plants CCP76/06 and CCP76/09 to water and saline stresses through biochemical and biophysics characteristics. The comparison among the grafted plants CCP76/06 and CCP76/09 showed different behaviors. The grafted CCP76/06 reproduced the behavior of stomatal opening of the rootstock CP06, which was more resistant to the effects of the water and saline stresses than the CCP9 and, therefore, it should have a better adaptation to CCP76/6 under those stresses. The preponderant participation of the rootstock in the regulation of the íons absorption and gas exchanges in dwarf cashew nut tree are also discussed.
