Drought resistance of crops is one of the great challenges for the world's agricultural systems. Although the concept of 'drought hardening' has been known for many years, very little has been done on pre-harvest treatment that can help leafy vegetable crops resist drought stress on a retailer's shelf. Our hypothesis was that for pot-grown vegetables a saline treatment could be found that would reduce transpiration pre- and post-harvest, but not harvestable yield. Coriander (Coriandrum sativum L.) was used as a model plant; several accessions (k-4, k-43, k-52, k-60 and k-62) from N.I. Vavilov Research Institute of Plant Industry, Russia and two commercial cultivars-Kashmir and Americanum-were studied. Plant growth, weight, transpiration, net CO2 assimilation, respiration, wilting, apparent petioles rigidity, leaf sodium content, elemental analysis and osmotic potential were assessed. We found that minor salinity (12.5 mM Na2SO4) triggered both drought and salt resistance mechanisms, which regulate appearance and shelf-life of pot-grown coriander. We found that the drought avoidance mechanisms (i.e. decreased transpiration and increased water use efficiency) and salt tolerance mechanisms induced by pre-harvest treatment could significantly postpone wilting and improve post-harvest habit of a leafy vegetable crop.
