Abstract

Sustainable agricultural techniques are essential strategies to cope with ever-increasing multiple stress factors that restrict the agriculture worldwide. KNO3 pulverization treatment, as one of common practices performed by farmers, has proven to support plant growth against environmental stressors. The present study was, thus, conducted to reveal the physiological and agronomic responses of grafted and own rooted ‘Italia’ grapevines to KNO3 pulverizations in soilless culture under protected cultivation on the face of climate change. Canopy pulverization with KNO3 (three times per vegetation) did not show adverse effect on stomatal conductance while it regulated the leaf temperature to recommended values at hot period of summer season. Grape berry and cluster features were improved by KNO3 pulverizations in especially grafted grapevines. KNO3 strengthened the berry adherence to rachis and affected the berry ripening by increasing the total soluble solid content of the must. The physiological mechanisms driving the accumulation of K+ though the canopy and into the grape berry compartments is worthy for much more detailed exploration on its mitigating effects of environmental stress factors.
