A kinetic model for estimating net photosynthetic rates of cos lettuce leaves under pulsed light
Photosynthesis Research, 2015Time-averaged net photosynthetic rate (P n) under pulsed light (PL) is known to be affected by the PL frequency and duty ratio, even though the time-averaged photosynthetic photon flux density (PPFD) is unchanged. This phenomenon can be explained by considering that photosynthetic intermediates (PIs) are pooled during light periods and then consumed by

Functional Ecology, 2005
Summary We had two objectives: (i) to determine the generality of, and extend the applicability of, a previously reported empirical relationship between leaf‐level net photosynthetic rate (AM, nmol g−1 s−1), specific leaf area (SLA, m2 kg−1) and leaf nitrogen mass fraction (NM, mmol g−1); and (ii) to compare these empirical results with a mechanistic ...

Phytoecdysteroids are steroid compounds present in many plant species (sometimes in rather large amounts), but their biological role is still far from being clear. We have found that the exogenous application of 20-hydroxyecdysone (20E) to leaves of Tetragonia tetragonioides L. causes stimulation of its net photosynthetic rate (P N) but

A Severe Drought: Impact on Tree Growth, Phenology, Net Photosynthetic Rate and Water Relations
American Midland Naturalist, 1979An unusually severe drought occurred in central Missouri during the summer of 1976. The drought resulted in an average soil water potential of ?26.1 bars in the upper 45 cm of soil profile in spite of the addition of 4.9 cm of irrigation water. It enabled us to examine its effects on phenology, growth and physiological processes, as well as the water ...

Abstract Node cuttings of in vitro chrysanthemum (1.0 cm) were transplanted on MS basal media supplemented with 30 g l−1 sucrose and cultured for 35 days under six different light qualities: fluorescent (FL), blue LEDs (B), red LEDs (R), red and blue LEDs (RB), red and far-red LEDs (RFr), and blue and far-red LEDs (BFr).

A Search for High Net Photosynthetic Rate among Soybean Genotypes1
Crop Science, 1969Two thousand four hundred and fifty‐eight genotypes of soybean (Glycine max (L.) Merr.) were screened for survival at a low carbon dioxide concentration near the CO2 compensation point of Zea mays L. Survival in such an atmosphere requires a low CO2 compensation point and indicates a high maximum net photosynthetic rate. None survived.

Table ADC-225-MK3 CO2 gas analyzer and PAM-2000 portable fluorescence measurement system were used to measure the net photosynthetic rate (Pn), initial fluorescence (Fo), maximal photochemical efficiency of PS II (Fv/Fm) and electron transport rate (ETR) of satsuma mandarin (Citrus unshiu Marc.) and navel orange (C. sinensis Osbeck) leaves. The results
