“…Air humidity has been shown to affect stomatal morphology and responsiveness in various angiosperm species. High relative air humidity during growth has been associated with longer and more open stomata (Torre et al, 2003;Nejad and van Meeteren, 2005;Fanourakis et al, 2011;Aliniaeifard et al, 2014), lower levels of ABA (Zeevaart, 1974;Nejad and van Meeteren, 2007;Okamoto et al, 2009;Aliniaeifard et al, 2014), and decreased stomatal responsiveness to ABA (Pospíšilová, 1996;Fanourakis et al, 2013;Pantin et al, 2013b;Arve et al, 2014). Exposure to low RH can enhance stomatal ABA responsiveness in young leaves that are constantly in a microenvironment with high RH (Pantin et al, 2013b).…”

, climate, and air humidity affect plant gas exchange that is controlled by stomata, small pores on plant leaves and stems formed by guard cells. Evolution has shaped the morphology and regulatory mechanisms governing stomatal movements to correspond to the needs of various land plant groups over the past 400 million years. Stomata close in response to the plant hormone abscisic acid (ABA), elevated CO 2 concentration, and reduced air humidity. Whether the active regulatory mechanisms that control stomatal closure in response to these stimuli are present already in mosses, the oldest plant group with stomata, or were acquired more recently in angiosperms remains controversial. It has been suggested that the stomata of the basal vascular plants, such as ferns and lycophytes, close solely hydropassively. On the other hand, active stomatal closure in response to ABA and CO 2 was found in several moss, lycophyte, and fern species. Here, we show that the stomata of two temperate fern species respond to ABA and CO 2 and that an active mechanism of stomatal regulation in response to reduced air humidity is present in some ferns. Importantly, fern stomatal responses depend on growth conditions. The data indicate that the stomatal behavior of ferns is more complex than anticipated before, and active stomatal regulation is present in some ferns and has possibly been lost in others. Further analysis that takes into account fern species, life history, evolutionary age, and growth conditions is required to gain insight into the evolution of land plant stomatal responses.

“…A review article of Fanourakis et al (2013) provides a quite complete overview on factors influencing vase life. They describe pre-harvest factors (environmental factors and genetics) and post-harvest factors (harvest factors, cutting and conditioning methods, test room conditions and vase life terminating symptoms) influencing vase life.…”
