Does Increased Leaf Appearance Rate Enhance Adaptation to Postanthesis Drought Stress in Sorghum?
Crop Science, 2011ABSTRACTIncreased leaf appearance rate (LAR) could reduce preanthesis water use of sorghum [Sorghum bicolor (L.) Moench] by restricting plant size via reduced tillering. The aim of this paper was to assess LAR as a potential pathway for adaptation to postanthesis drought stress.

SWITCHGRASS LEAF APPEARANCE AND LAMINA EXTENSION RATES IN RESPONSE TO FERTILIZER NITROGEN
Journal of Plant Nutrition, 2002 ABSTRACT Quantification of effects from factors known to modify vegetative development and growth in grasses is important in modeling biomass yield. The objective of this study was to measure the effects of increasing levels of N on leaf appearance (LAR) and lamina extension rates (LER) in switchgrass (Panicum virgatum L.) under field and controlled ...

Interaction of temperature and daylength on leaf appearance rate in wheat and barley
Agricultural and Forest Meteorology, 1998A common way of describing wheat phenology during the leaf development stage is by reporting the number of leaves on the main stem. The ability to predict the timing of successive leaf appearance is important because it impacts on the timing of certain developmental stages of the plant and on the rate of leaf area expansion. Therefore, most crop models

Euphytica, 1990 Evidence of genetic variation for early vigour is presented using maize line × tester crosses. The leaf appearance rate and associated variance components are affected by a physiological stress attributable to the transition to autotrophic nutrition by the plant.

Annals of Applied Biology, 1989 SummaryExamination of the time courses, expressed in terms of accumulated temperature over 0°C, of leaf appearance of fifteen sowings of winter wheat, including five cultivars, over three seasons at Auchincruive, revealed several examples of bi‐linear rather than linear responses.

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.

Rate of leaf appearance in sugarcane, including a comparison of a range of varieties
Australian Journal of Plant Physiology, 1998Leaf appearance rate is a major determinant of canopy establishment, radiation interception and therefore yield. The effect of genotype on leaf appearance rate in sugarcane is largely unknown. Leaf appearance rate was recorded for the mainstems of pot grown sugarcane plants of nine commercial varieties, over 10 months in Townsville, Australia.

Crop Science, 1984 Tiller density and yield/tiller are yield components associated with dry matter productivity of grasses. Breeding programs may benefit by exploiting the mechanisms that control growth and development of these components. Our objective was to evaluate the relationship between leaf appearance and tillering in seedlings of tall fescue (Festuca arundinacea
