Humidity does not appear to trigger leaf out in woody plants
International Journal of Biometeorology, 2017In order to anticipate the ecological impacts of climate change and model changes to forests, it is important to understand the factors controlling spring leaf out. Leaf out phenology in woody trees and shrubs is generally considered to be strongly controlled by a combination of spring warming, winter chilling requirement, and photoperiod.

A leaf-mimicking moth uses nanostructures to create 3D leaf shape appearance
Current BiologyNature provides many astonishing examples of visual deception, from fish that resemble leaves to spiders and butterfly pupae that look like bird droppings or moth larvae that bear a striking resemblance to the head and neck of a tree snake.1,2 Most types of camouflage rely on preventing object detection, but this strategy of resemblance, known as ...

Effects of photoperiod on leaf appearance rate and leaf dimensions in winter and spring wheats
Canadian Journal of Plant Science, 1996Research on genotypic variation in the response of leaf-area production and expansion to photoperiod in wheat is limited. Growth-cabinet experiments using four spring and four winter wheat (Triticum aestivum L.) cultivars and four photoperiod (8, 12, 16 and 20 h) treatments were thus conducted with the objective of investigating the effect of ...

Response of white clover (Trifolium repens L.) leaf area to water deficit depends on three processes: individual leaf expansion, phytomer production, and stolon branching. We have evaluated these processes in five clones under a wide range of conditions.

Winter Wheat Mainstem Leaf Appearance and Tiller Formation vs. Moisture Treatment
Agronomy Journal, 1991AbstractMainstem leaf (MSL) appearance and percent tiller formation (%TF) have been used to evaluate wheat (Triticum aestivum L.) development. The assumption is that MSL appearance is a linear relationship to accumulated heat or growing degree days (GDD) and is unaffected by other environmental factors.

Temperature response function for leaf appearance rate in wheat and corn
Canadian Journal of Plant Science, 1999The ability to predict leaf appearance would enhance our capability of modeling plant development and the rate of leaf area expansion. Many crop models use the constant thermal time for successive leaf tip appearance (which is often termed a phyllochron) as one model parameter to predict total number of leaves and date of anthesis.

The Impact of Temperature on Leaf Appearance in Bambara Groundnut Landraces
Crop Science, 2003Ten bambara groundnut [Vigna subterranea (L.) Verdc] landraces of diverse origin were used to examine the effect of temperature on the rate of leaf appearance (RLA) and to determine the base temperature (Tb) among landraces. Knowledge of leaf development is required in breeding programs where crop morphological development is considered an important ...
