Leaf appearance and senescence patterns of some pasture species
Grass and Forage Science, 1995AbstractFive pasture species, very different in their morphological organization (four dicotyledons: Plantago lanceolata, Sanguisorba minor, Ranunculus repens, Taraxacum officinalis and one grass: Dactylis glomerata), were grown as spaced plants in pots, thus excluding competition for light, to study the proportion of senescent leaves.

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 ...

Prediction of leaf appearance in wheat: a question of temperature
Field Crops Research, 1995Abstract The rate of leaf appearance in wheat depends on temperature. When the rate is expressed in thermal time based on air temperature, a marked contrast is apparent between autumn and spring sowings. This variation has often been attributed to a preconditioning response that determines the thermal phyllochron at about the time of emergence ...

Leaf area growth and nitrogen concentration per unit leaf area, N-a (g m(-2) N) are two options plants can use to adapt to nitrogen limitation. Previous work indicated that potato (Solanum tuberosum L.) adapts the size of leaves to maintain Na and photosynthetic capacity per unit leaf area.

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.

Relationships between internode elongation, plant height and leaf appearance in maize
Field Crops Research, 1994Abstract Two field studies were undertaken to formulate relationships between leaf appearance, leaf height and plant height in maize which could be used in models of light competition in intercropping systems. In the first study a single hybrid was subjected to three water-stress treatments: mild stress, severe stress and well-watered conditions ...
