The setting of rates of development of wheat plants at crop emergence: Influence of the environment on rates of leaf appearance

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.

DIFFERENCES IN RATES OF LEAF APPEARANCE AMONG MAIZE HYBRIDS AND PHASES OF DEVELOPMENT

Canadian Journal of Plant Science, 1984
Rates of leaf appearance were evaluated for three maize (Zea mays L.) hybrids grown at two day/night temperatures (20/17 °C and 30/27 °C) in environmentally controlled growth facilities, and for 10 maize hybrids grown in the field. Differences in rate of leaf appearance occurred among genotypes and among phases of development for maize hybrids grown ...

Rice crop duration and leaf appearance rate in a variable thermal environment. II. Comparison of genotypes [PDF]

Field Crops Research, 1998
Abstract Rice crop duration in tropical-arid, irrigated environments, such as the Sahel, varies strongly among seasons and years. For rice double-cropping systems, cultivars are needed that have a stable duration under variable daylengths and temperatures.

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 ...

Does Increased Leaf Appearance Rate Enhance Adaptation to Postanthesis Drought Stress in Sorghum?

Crop Science, 2011
ABSTRACTIncreased 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.

Contribution of Leaf Expansion, Rate of Leaf Appearance, and Stolon Branching to Growth of Plant Leaf Area under Water Deficit in White Clover

Crop Science, 1996
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.

Rice crop duration and leaf appearance rate in a variable thermal environment. III. Heritability of photothermal traits [PDF]

Field Crops Research, 1998
Abstract In arid, irrigated, rice environments, crop duration is highly variable, resulting in uncertain crop calendars for double cropping. The main causes of this variability are varying temperature and daylength. Breeding for stable crop duration in such environments might make a major contribution to rice production.

Rate of leaf appearance in sugarcane, including a comparison of a range of varieties

Australian Journal of Plant Physiology, 1998
Leaf 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.

Corn Growth Response to Temperature and Photoperiod II. Leaf‐Initiation and Leaf‐Appearance Rates¹

Agronomy Journal, 1983
AbstractThe prediction of evapotranspiration and canopy photosynthesis, for example in crop simulation modeling and in remote sensing applications, requires a quantitative description of the influence of environmental factors such as temperature and photoperiod on leaf area development.

Leaf appearance rate and associated characters in some Mexican and Australian wheats

Australian Journal of Agricultural Research, 1974
Three Mexican cultivars of high yield potential were compared in four field sowings with three Australian varieties of similar flowering time. The cultivars had different numbers of leaves on the main stem, associated mainly with differences in rate of leaf appearance rather than duration of leaf production.
