Co-ordination between leaf initiation and leaf appearance in field-grown maize (Zea mays): genotypic differences in response of rates to temperature.
BACKGROUND AND AIMS In maize (Zea mays), early flowering date, which is a valuable trait for several cropping systems, is associated with the number of leaves per plant and the leaf appearance rate. Final leaf number depends upon the rate and duration of leaf initiation. The aims of this study were to analyse the genotypic variation in the response to temperature of leaf appearance rate and lea...
متن کاملIncorporating a chronology response into the prediction of leaf appearance rate in winter wheat.
The prediction of leaf appearance rate (LAR) is an important part of many crop simulation models. Most wheat simulations models assume that LAR is affected by temperature and photoperiod. This assumption ignores the fact that seed reserves contribute to a greater LAR of the first two leaves and that the LAR of subsequent leaves decreases as a result of an increase in the distance that each leaf...

Inhibitory effects of water deficit on maize leaf elongation.
The growth rate of maize leaves has been investigated for plants grown in pots in controlled conditions and subjected to slow drying over a period of days. The elongation of leaves experiencing water deficit was inhibited primaily during the afternoon. No decrease in the turgor of the growing cells could be detected at that time. Solute concentration in the growing cells increased in tissue exp...
متن کاملSpring wheat leaf appearance and temperature: extending the paradigm?
Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates. To test this hypothesis, leaf appearance in spring wheat ('Nordic') ...
