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

Which of the following definitions best describes 'Grain number per panicle - Computation'?

A. Calculate using the formula.
B. Cellulose concentration obtained from the Van Soest reference analyses, predicted using a Near Infra Red Spectroscopy (NIRS) calibration and calculated in reference to the Cell Wall Residue (CWR) content (estimated through the Neutral Detergent Fiber, NDF). The NIRS calibration information has to be provided. Method abbreviation: VSCellNDFNIRS.
C. Calculate the dry weight of the organs of a pool of n plants, based on the fresh weight of the organs of n plants and the dry matter content of the organ. Here the dry matter content of the tillers is calculated as the average dry matter of the different organs of the main shoot (the hypothesis is that the tillers have the same proportions of the different organs than the main shoot, what is wrong). The number of plants (n) must be provided. Recommended range for n is 3 to 6.
D. The P2R respresents the photoperiod sensitivity computed according to the CERES model. CERES model considers that, above criticial photoperiod (P2O), a linear growth of the duration of the vegetative phase (in degree days) as a function of photoperiod. The slope of this line (P2R) defines photoperiod-sensitivity.

Answer: Calculate using the formula.
