Leaf economics spectrum–productivity relationships in intensively grazed pastures depend on dominant species identity

Plant functional traits are thought to drive variation in primary productivity. However, there is a lack of work examining how dominant species identity affects trait-productivity relationships. The productivity of 12 pasture mixtures was determined in a 3-year field experiment. The mixtures were based on either the winter-active ryegrass (Lolium perenne) or winter-dormant tall fescue (Festuca ...

Barley Leaf Area and Leaf Growth Rates Are Maximized during the Pre-Anthesis Phase

Leaf developmental traits are an important component of crop breeding in small-grain cereals. Surprisingly, little is known about the genetic basis for the differences in barley (Hordeum vulgare L.) leaf development. The two barley row-type classes, i.e., twoand six-rowed, show clear-cut differences in leaf development. To quantify these differences and to measure the genetic component of the p...

Simultaneous monitoring of leaf growth and leaf movement.

Leaves experience predictable 24-h (diel) fluctuations in environmental factors such as light and temperature, as well as in energy availability. Accordingly, leaf growth is among the many processes regulated by the circadian clock. Despite the importance of leaf growth to the plant, it is relatively poorly understood, in large part due to the difficulty of tracking growth in leaves compared wi...
