Leaf appearance rate and final main stem leaf number as affected by temperature and photoperiod in cereals grown in Mediterranean environment

Ruminal Methane Emission, Microbial Population and Fermentation Characteristics in Sheep as Affected by Malva sylvestris Leaf Extract: in vitro Study

The objective of this study was to investigate in vitro effect of Malva sylvestris leaf extract (at 0, 25, 50 and 100 µL/30 mL of medium) on sheep ruminal cellulolytic and total viable bacteria growth, protozoa populations, methane production, neutral detergent fiber degradability (NDFD) and fermentation efficiency of oat hay. The addition of Malva sylvestris leaf extract at 25, 50 and 100 µL l...

Plasticity of leaf anatomy, chemistry and water economy of irrigated sugar beets grown under Mediterranean conditions

  In a three-year (2004-2006), field experiment, we aimed to study changes in leaf physiological traits (leaf water potential-Ψleaf, leaf water content-LWC, carbon isotope discrimination-Δ, specific leaf area-SLA, chlorophyll content as assessed by SPAD and modified SPAD-MSPAD) and elemental composition (K, Na, Ca, Mg, K/Na, Ca/Mg, total leaf salinity-TLS) of sugar beets (cv. Rizor) grown unde...

Apparent photosynthesis of soybean plants as affected by changes in leaf water potential under field conditions

Spring 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') ...

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...
