This study tests the hypothesis that a more salt-excluder rootstock can attenuate salt stress in grapevine plants by enhancing photosynthesis and providing ionic oxidative protection. Plants of 'BRS Vitória' variety, grafted with rootstocks IAC 313 (salt-excluder) SO4, were subjected to salinity adding NaCl (0, 50, 100 mM) for 30 days. SO4 showed severe toxicity symptoms leaves lower chlorophyll content under salinity. Conversely, improved stomatal conductance, along higher carboxylation...
Understanding the leaf area is essential in plant physiology and ecological studies, as it directly influences photosynthesis, transpiration productivity.
