Abstract
Avenues to increase the degree of certainty that the cut flower will last a minimum length of time (concept of vase life guarantee) are highly needed.
Limited stomatal control of transpiration leads to early vase life termination associated with lethal wilting symptoms.
In this survey, the role of cultivation environment on determining leaf stomatal functioning is reviewed together with recent evidence on the effect of supply chain conditions.
On a complementary view, the importance of non-leaf tissues for whole-cut flower water loss is discussed as an additional trait to improve cut flower water relations.
Excessive ozone uptake, high relative air humidity (RH ≥85%), low air velocity, and continuous light during cultivation disturb stomatal functioning.
Notably, the high RH-induced adverse effect can be mitigated by several cultivation techniques.
Increased light intensity, monochromatic red light and low RH (40%) during cultivation stimulate stomatal functioning.
Mid-term exposure to elevated ozone concentration (2 d) or high RH (4-7 d), and long-term exposure (28 d) to low temperature (0.5°C) during the supply chain attenuate stomatal functioning depending on the species.
Robust non-invasive techniques to evaluate overall stomatal responses are available.
Alternatively, when relevant preharvest and postharvest climatic data are accessible, an indication of stomatal functioning may be deduced.
Based on this, batches with low potential vase life may be isolated, assisting handling protocols as well as pricing and customer suitability decisions.
