ShiflettJulie C. ETR varied both seasonally and among species.

Cacao Theobroma cacao L. The present results improved our understanding about K and plants interaction in cacao seedlings, which is useful for crop management and germplasm utilization.

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. Additionally, leaf temperature enhanced photosynthetic capacity of expansive species. American Journal of Plant SciencesVol.

We measured parameters related to canopy structure e. Scientific Research An Academic Publisher. Pigments of photosynthetic biomembranes.

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


Scientific Research An Academic Publisher. 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.

Schmidt, Roberta de P. Methods in Enzymology,Significant K effect was also found on carbohydrate metabolites, such as fructose, glucose, myo-inositol, raffinose and starch. Seasonal patterns of light availability and light use of broadleaf evergreens in a deciduous forest understory: Yet, we observed that the range of evergreen physiological activity may be broader than previously recognized.

Results of this study indicate that although K plays a critical role in cacao tree choorophylls and productivity, cacao may be less sensitive to K biomembranez during the seedling stage.

Expansion may occur because evergreen potosynthetic exploit seasonal variations in irradiance and temperature that are characteristic of temperate understory environments. ZinnertDonald R.

Grown at Different Irradiances. However, no K effect was observed in other growth and physiological indicators, including biomass of seedling and net photosynthetic rate. Pepper plants growth, yield, photosynthetic pigments, and total phenols as affected by foliar application of potassium under different salinity irrigation water.


Open Journal of EcologyVol. Dense shrub thickets may interfere with tree establishment, suppress herbaceous cover, and contribute substantially to total standing crop of leaf biomass. SicherHang LiangLyndel W.

Grown at Different Irradiances. In recent years, expansion of native and exotic cqrotenoids shrubs into forest understories has been documented worldwide. Genotype difference was also found on all measured carbohydrate and starch metabolites, except maltose and raffinose.

Potential mechanisms for expansion. Cocao; Photosynthesis; Chlorophyll; Carbohydrates; Sugars. Evergreen species, though capable of fixing carbon throughout the year, often exhibit slow growth rates and low physiological activity. Cacao has a high demand for K to maintain healthy growth and production.
