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. Cacao Theobroma cacao L. Cacao has a high demand for K to maintain biomembrames growth and production. Grown at Different Irradiances. 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.


Potential mechanisms for expansion. Evergreen species, though capable of fixing carbon throughout the year, often exhibit slow growth rates and low physiological activity.

Seasonal patterns of light availability and light use of broadleaf evergreens in a deciduous forest understory: 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 photosynthhetic soil K supply. However, no K effect was observed in other growth and physiological indicators, including biomass of seedling and net photosynthetic rate.

Dense shrub thickets may interfere with tree establishment, suppress herbaceous cover, and contribute substantially to total standing crop of leaf biomass. Schmidt, Roberta de P. Additionally, leaf temperature enhanced photosynthetic capacity of expansive species. Scientific Research An Academic Publisher.

Genotype difference was also found on all measured carbohydrate pgments starch metabolites, except maltose and raffinose. Grown at Different Irradiances. American Journal of Plant SciencesVol. Significant K effect was also found on carbohydrate metabolites, such as fructose, glucose, myo-inositol, raffinose and starch. Methods in Enzymology,In recent years, expansion of native and exotic evergreen shrubs into forest understories has been documented worldwide.


Scientific Research An Academic Publisher. 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.

Expansion may occur because evergreen shrubs exploit seasonal variations in irradiance and temperature that are characteristic of temperate understory environments. Yet, we observed that the range of evergreen physiological activity may be broader than previously recognized. ETR varied both seasonally and among species.

We measured parameters related to canopy structure e. Pepper plants growth, yield, photosynthetic pigments, and total phenols as affected by foliar application of potassium under different salinity irrigation water.
