Kiwi fruit displays chlorophyll fluorescence. A physical model was developed to reproduce the observed original fluorescence for the whole fruit, from the emission of the different parts of the kiwi fruit. The spectral distribution of fluorescence in each part of the fruit, was corrected to eliminate distortions due to light re-absorption and it was analyzed in relation to photosystem II-photosystem I ratio. Kiwi fruit also displays variable chlorophyll-fluorescence, similar to that observed from leaves. The maximum quantum efficiency of photosystem II photochemistry (F(v)/F(m)), the quantum efficiency of photosystem II (Φ(PSII)), and the photochemical and non-photochemical quenching coefficients (q(P) and q(NP) respectively) were determined and discussed in terms of the model developed. The study was extended by determining the photosynthetic parameters as a function of the storage time, at both 4 °C and room temperature for 25 days.

The main goal of the present work was to clarify physiological strategies in plants whose chloroplasts were developed under different light environments. The specific objective was to elucidate the in...
Cyanobacteria are photosynthetic prokaryotes and widely used for photosynthetic research as model organisms. Partly due to their prokaryotic nature, however, estimation of photosynthesis by chlorophyl...
Increased eutrophication in the recent years has resulted in considerable research focus on identification of methods for preventing cyanobacterial blooms that are rapid and efficient. The objectives ...
In order to increase the monitoring capabilities of inland and coastal waters, there is a need for new, affordable, sensitive and mobile instruments that could be operated semi-automatically in the fi...
Seven kinds of indigenous fruits and five imported fruits were compared for their "health quality." Methods including the calorific, antioxidant, and ion ratios were carried out. Results indicated the...
The purpose of this study is to determine whether the intake of kiwi fruits will reduce systolic and diastolic blood pressure compared to intake of apples. The investigators hypothesize th...
The aim of this study was to evaluate the efficacy of PG102 at lowering levels of total IgE in asymptomatic subjects with atopy.
Current evidence indicates that fruit and vegetable intake and dietary patterns rich in fruit and vegetables may be associated with reduced insulin resistance and may reduce the risk of th...
The purpose of this study is to determine whether consumption of the active product affects postprandial changes in metabolic indices, in comparison to the control product.
This is a randomized controlled trial to assess the impact of a novel fruit and vegetable mobile phone application on fruit and vegetable intakes, knowledge and attitudes.
A plant family of the order Theales, subclass Dilleniidae, class Magnoliopsida. It is best known for Kiwi fruit (ACTINIDIA).
Measurement of the intensity and quality of fluorescence.
Widely distributed unicellular or multicellular bacteria. The CYANOBACTERIA use chlorophyll a and phycobilins for oxygenic photosynthesis while genera in the Prochlorales use both chlorophyll a and b but not phycobilins.
An analytical method for detecting and measuring FLUORESCENCE in compounds or targets such as cells, proteins, or nucleotides, or targets previously labeled with FLUORESCENCE AGENTS.
A type of FLUORESCENCE SPECTROSCOPY using two FLUORESCENT DYES with overlapping emission and absorption spectra, which is used to indicate proximity of labeled molecules. This technique is useful for studying interactions of molecules and PROTEIN FOLDING.
