How to Diagnose Potassium Abundance and Deficiency in Tomato Leaves at the Early Cultivation Stage

Horticulturae, 2023
Potassium is one of the indispensable nutrient elements for plant growth, fruit development, and yield. The research and application of potassium nutrition diagnosis technology is the premise of scientific potassium management.

Photosystem II Photosynthetic Unit Sizes from Fluorescence Induction in Leaves [PDF]

Plant Physiology, 1981
The use of fluorescence induction measurements in leaves infiltrated with 3-(3,4-dichlorophenyl)-1,1-dimethylurea has been evaluated as a routine method for estimation of the concentration of the reaction centers of photosystem II relative to total chlorophyll in a wide variety of plant species. The procedure is based on a simple theory that takes into

Higher Stomatal Density Improves Photosynthetic Induction and Biomass Production in Arabidopsis Under Fluctuating Light

Frontiers in Plant Science, 2020
Stomatal density (SD) is closely associated with photosynthetic and growth characteristics in plants. In the field, light intensity can fluctuate drastically within a day.

Concurrent Increases in Leaf Temperature With Light Accelerate Photosynthetic Induction in Tropical Tree Seedlings

Frontiers in Plant Science, 2020
Leaf temperature changes with incident light intensity, but it is unclear how the concurrent changes influence leaf photosynthesis. We examined the time courses of CO2 gas exchanges and chlorophyll fluorescence of seedling leaves in four tropical tree ...

Speed of light-induced stomatal movement is not correlated to initial or final stomatal conductance in rice

Photosynthetica, 2022
In nature, plants are often confronted with wide variations in light intensity, which may cause a massive carbon loss and water waste. Here, we investigated the response of photosynthetic rate and stomatal conductance to fluctuating light among ten rice ...

Effect of Cameraria ohridella feeding on Aesculus hippocastanum photosynthesis

Regulatory Mechanisms in Biosystems, 2021
The complex of invasive species of phytophagous insects that can adapt to novel living conditions is constantly increasing. The ecological effect of their vital activity in the new environment is almost impossible to predict.

Microaerophilic growth and induction of the photosynthetic reaction center in Rhodopseudomonas viridis

Journal of Bacteriology, 1989
Rhodopseudomonas viridis was grown in liquid culture at 30 degrees C anaerobically in light (generation time, 13 h) and under microaerophilic growth conditions in the dark (generation time, 24 h). The bacterium could be cloned at the same temperature anaerobically in light (1 week) and aerobically in the dark (3 to 4 weeks) if oxygen was limited to 0.1%

Regulation of Photosynthetic Induction State by the Magnitude and Duration of Low Light Exposure [PDF]

Plant Physiology, 1994
This study was undertaken to examine the dependence of the regulatory enzymes of photosynthetic induction on photon flux density (PFD) exposure in soybean (Glycine max L.). The induction state varies as a function of both the magnitude and duration of the PFD levels experienced prior to an increase in PFD.

Effects of saturation flash protocols on photosynthetic induction and assessment of mesophyll conductance and maximum carboxylation rate sensitivity to parameter inputs in Ficus carica

Frontiers in Plant Science
Improving photosynthetic efficiency during the induction phase is a key strategy for enhancing plant productivity. A critical prerequisite for achieving this goal is identifying the limitation factors that affect photosynthesis during induction.
