Staying green postharvest: how three mutations in the Arabidopsis chlorophyll b reductase gene NYC1 delay degreening by distinct mechanisms.

Journal of Experimental Botany, 2015
Stresses such as energy deprivation, wounding and water-supply disruption often contribute to rapid deterioration of harvested tissues. To uncover the genetic regulation behind such stresses, a simple assessment system was used to detect senescence ...

Elektrochromie von Chlorophyll-a und Chlorophyll-b in monomolekularen Filmen / Electrochromie Effects of a Chlorophyll a and a Chlorophyll b Monolayer

Zeitschrift für Naturforschung B, 1969
A electric field induced linear and quadratic change in the optical absorption of a chlorophyll a and chlorophyll b monolayer is reported. The chlorophylls are incorporated in a fatty acid monolayer condenser which allows the application of external field strength up to 4 · 106 V/cm. The spectrum of the quadratic electrochromic effect shows evidence of

Chlorophyll a + b Content and Chlorophyll Fluorescence in Avocado

Journal of Agricultural Science, 2012
Tonnage (T), Simmonds (S) avocado trees, and TxS crosses were evaluated for differences in chlorophyll content and maximal quantum yield of photosystem II in sun and shade-type leaves. Total chlorophyll content by area (Chl a+bar) ranged from 984 mg m -2 in TxS240 to 4320 mg m -2 in Simmonds.
