We measured parameters related to canopy structure e. Evergreen species, though capable of fixing carbon throughout the year, often exhibit slow growth rates and low physiological activity.

In recent years, expansion of native and exotic evergreen shrubs into forest understories has been documented worldwide.

Potential mechanisms for expansion. Schmidt, Roberta de P. Additionally, leaf temperature enhanced photosynthetic capacity of expansive species. Grown at Different Irradiances. Seasonal patterns of light availability and light use of broadleaf evergreens in a deciduous forest understory: American Journal of Plant SciencesVol.

Yet, we observed that the range of evergreen physiological activity may be broader than previously recognized.

Genotype difference was also found on all measured carbohydrate and starch metabolites, except maltose and raffinose. Open Journal of EcologyVol. The present results improved our understanding about K and plants interaction in cacao seedlings, which is useful for crop management and germplasm utilization.

Pepper plants growth, yield, photosynthetic pigments, and total phenols as affected by foliar application of potassium under different salinity irrigation water. Cacao has a high demand for K to maintain healthy growth and production.

Scientific Research An Academic Publisher. Grown at Different Irradiances. ZinnertDonald R. ETR varied both seasonally and among species. Expansion may occur because evergreen shrubs exploit seasonal variations in irradiance and temperature that are characteristic of temperate understory environments.

Dense shrub thickets may interfere with tree establishment, suppress herbaceous cover, and contribute substantially to total standing crop of leaf biomass.

Cacao Theobroma cacao L. Scientific Research An Academic Publisher. We quantified leaf-level light environment and photosynthetic activity of three sympatric broadleaf evergreens Ilex opaca, Kalmia latifolia, and Myrica cerifera in a deciduous forest understory in Charles City County,Virginia,USAin order to understand seasonal intra- and interspecific ranges of broadleaf evergreen physiology.

Schmidt, Roberta de P. Results of this study indicate that although K plays a critical role in cacao tree growth and productivity, cacao may be less sensitive to K deficiency during the seedling stage.

Pigments of photosynthetic biomembranes. Knowledge of K use in cacao will help the development of suitable crop management practices and will aid breeding varieties adapted to environments with a limited soil K supply.

Furthermore, our results indicate potential for changes in composition and expansion of the evergreen shrub layer by species that exhibit structural and physiological mechanisms advantageous for future rises in temperature.

Significant K effect was also found on carbohydrate metabolites, such as fructose, glucose, myo-inositol, raffinose photosybthetic starch. Methods in Enzymology, ,
