Light conditions during plant growth influence postharvest shelf life of Coriaria myrtifolia, a new plant for cut foliage.  Coriaria myttifolia is a native plant of the South-eastern Spain suitable for cut foliage.The objective of this work was to study the influence of the light intensity during cultivation and of different preservatives o­n postharvest shelf-life.

Plants of C. myrtifolia were cultivated in three shelters.The first shelter had 85% of natural light reduction, the second shelter had 65% of natural light reduction and the third shelter had 45% of natural light reduction.Plant density was 1 m-2.Plants were harvested three times (in spring, in summer and in autumn).After harvesting, all collected stems were classified in two groups, suckers and lateral stems, and placed in water to avoid dehydration.Then all stems were put in vases at room temperature with the following treatments: control (water), 2.5 g L-1 sucrose + 1 ml L-1 sodium hypochlorite, 2.5 g L-1 sucrose + 2 ml L-1 sodium hypochlorite and 2.5 g L-1 sucrose + 3 ml L-1 sodium hypochlorite.

Best production results were obtained with the least reduced light intensity in terms of number of suckers and stems, implying that Coriaria myrtifolia prefers higher light conditions.2.5 g L-1 sucrose + 2 ml L-1 sodium hypochlorite induced longer shelf life, regardless of the shelters used.In addition, the suckers had longer shelf life than the lateral stems.Larger diameter of both suckers and lateral stems enhanced postharvest shelf life.
