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

Which of the following definitions best describes 'Flag leaf angle estimation cult late'?

A. Count the number of filled spikelets per panicle. Repeat the measurement on other representative panicles. Take the average number of filled spikelets per panicle.
B. Collect 5-10 blooming florets of a male sterile line from different plants and measure the average angle of the opening between glumes (viz., lemma and palea)
C. Cultivated species: at anthesis, estimate the angle of attachment between the flag leaf blade and the main panicle axis, near to the collar of the leaf. Record the average of five flag leaves
D. Measure the length of main axis of the mature panicle on the main culm of five representative plants and calculate their average

Answer: Cultivated species: at anthesis, estimate the angle of attachment between the flag leaf blade and the main panicle axis, near to the collar of the leaf. Record the average of five flag leaves
