Task: Class Definition Understanding (ontology: Food_Agriculture/Crop_Ontology)

Which of the following definitions best describes 'FLeafSen Estimation'?

A. Rate using a scale from 0 (0% senescence) to 10 (100% senescence) using the guide, in increments of 10%.
B. Main shoots are assessed for sharp eyespot disease.
C. Standard method for karnal bunt incidence.
D. Record date of double ridge stage (DS14-15 approx.). Double ridge signifies that the plant?s main growing point will produce no more primordial leaves, and instead will produce primordial spikelets of the young spike. The dissection and observation of the main tiller apex on an optic magnifier is required.

Answer: Rate using a scale from 0 (0% senescence) to 10 (100% senescence) using the guide, in increments of 10%.
