3. Growth adaptations to high temperature
While extremely high temperature (e.g. heat-shock above 40°C) can be
detrimental (Camejo et al., 2006; Vara Prasad, Boote, Hartwell Allen Jr,
& Thomas, 2003; Yang, Sears, Gill, & Paulsen, 2002), a milder increase
in temperature can impact growth in two ways. First, warm temperature
can increase the rate of growth of a given organ and proportionally
decrease its growth duration without impacting the final plant body
(Heschel et al., 2007; Parent & Tardieu, 2012). Second, warm
temperature can accelerate growth impacting the plant body to improve
evaporative cooling, increasing convection and directly avoiding heat
flux from the sun (Havko et al., 2020; Rosado et al., 2019).
