The chlorophyll content of green callus cultures of Kalanchoë crenata was low in comparison with Kalanchoë leaves. A small quantity of β-carotene was detected in colourless callus together with auroxanthin and neoxanthin. The auroxanthin content decreased when colourless callus was greened on ...
A field experiment was conducted with two cassava cultivars and eight levels of nitrogen to examine the relationship between extractable chlorophyll (Chl) content of cassava leaves and both the Chl meter value (SPAD) and leaf colour chart (LCC) score. The SPAD, LCC, and Chl a+b content were...
The study's authors found over half the world's oceans,56%, experienced a change in colour.This is because of changes in the thickness and spread of plankton(浮游生物). These small living things contain chlorophyll(叶绿素),which helps plants get food from sunlight.The recent study supports a...
