As an important antioxidant for plants and humans, L-ascorbic acid (AsA, vitamin C) can scavenge reactive oxygen species (ROS) and can be regenerated from its oxidized form in a reaction catalyzed by ...
Stem reserve accumulation and mobilization in wheat (Triticum aestivum L.) as affected by sowing date and N – P – K levels under Mediterranean conditions
Dry matter mobilization efficiency N - P - K levels
2011/6/29
Some parts of the dry matter accumulated in the wheat stem during the vegetative period are translocated to grain during the grain-filling period. This study assesses the changes in dry matter accumul...
