Effects of graphene on morphology, microstructure and transcriptomic profiling of Pinus tabuliformis Carr. roots.

Graphene has shown great potential for improving growth of many plants, but its effect on woody plants remains essentially unstudied. In this work, Pinus tabuliformis Carr. bare-rooted seedlings grown outdoors in pots were irrigated with a graphene solution over a concentration range of 0-50 mg/L fo...
