Mutation of OsDET1 increases chlorophyll content in rice
Plant Science, 2013As an important agronomic trait, the chlorophyll (Chl) content is closely related to photosynthesis in plants. A rice mutant Gc (Oryza sativa indica) was characterized previously by its enhanced Chl content (Chl b and total Chl) and exaggerated photosynthetic rate.

Olive fruits of the Arbequina variety are differentiated from those of Hojiblanca and Picual by the differing presence of 132‐OH‐chlorophyllaand of dephytylated chlorophyll derivatives during the life cycle of the fruit. During the fruit growth stage, which coincides with chlorophyll synthesis, chlorophyllase (EC: 3.1.1.14) is present in the three ...

Nondestructive Method for Estimating Chlorophyll Content of Leaves
Science, 1961A quantitative relationship is shown to exist between the chlorophyll content of soybean and Valencia orange leaves and their percentage reflectance of light of wavelength 625 mμ as measured by a colorimeter with reflectance attachment.

Estimation of the chlorophyll content and yield of grain crops via their chlorophyll potential
Biophysics, 2017The results of the assessment of the relationship between the chlorophyll content, crop yield and chlorophyll potential of crops of wheat, barley, and oat are presented. The results of a ground-based remotesensing technique and laboratory data were used to accomplish this assessment.

QTL Mapping of Chlorophyll Contents in Rice
Agricultural Sciences in China, 2007Abstract The objectives of this study were to investigate the genetic factors controlling the chlorophyll content of rice leaf using QTL analysis. A linkage map consisting of 207 DNA markers was constructed by using 247 recombinant inbred lines (RILs) derived from an indica-indica rice cross of Zhenshan97B×Milyang 46.

Remote Sensing of Environment, 1998
Abstract Algorithms based on reflectance band ratios have been developed for the remote estimation of chlorophyll a , chlorophyll b , chlorophyll a+b , and total carotenoid content of Eucalyptus leaves. Reflectance spectra over the 400–2500 nm range with a spectral resolution of 2 nm and the content of chlorophylls a , b , a+b , and total ...

Content of chlorophylls and carotenes in rapeseed oil
Journal of the American Oil Chemists' Society, 1965AbstractThe content of the green components in crude rapeseed oil, namely chlorophylls A and B, as well as the products of their decomposition pheophytins A and B, were determined by means of the spectrophotometric method of analysis.No chlorophyll A was found in any of the analyzed samples but the content of pheophytin A was quite high and amounted to

The Chlorophyll Content of Arctic Sea-Ice
ARCTIC, 1961A number of observers, working in arctic and antarctic waters, have commented on the discoloration of sea-ice caused by unicellular algae, mainly diatoms, that are frozen into the ice. The discoloration is usually seen when the ice is broken and over turned, because it occurs principally on the lower surface of the ice and occasionally on its sides ...

Light Acclimation of Leaf Chlorophyll Content
2008We Studied Light Acclimation Of Leaf Chlorophyll (Chl A) And Nitrogen (Na) Contents Per Unit Area, And Leaf Dry Mass Per Unit Area (Lma) Along A Vertical Light Gradient In Natural Herbaceous And Tree Canopies. We Found That Lma Increased Strongly With Increasing Irradiance In The Tree Canopy But Not In The Herbaceous Canopy, And That Chl A Was Much ...

Chlorophyll a fluorescence, photosynthesis activity and chlorophyll content in senescing leaves
2015Leaf senescence is the last step of leaf development and can be induced by many genetic and environmental factors. The chloroplast and many leaf pigments undergo a progressive degeneration. The leaf functionality is slowed down and several physiological processes are altered.
