A) \[{{P}_{760}}\]
B) \[{{P}_{730}}\]
C) \[{{P}_{650}}\]
D) all of these
Correct Answer: C
Solution :
The seed germination is promoted by red wavelength (650 nm) and inhibited by far red (730 nm), this is due to the pigment phytochrome behaving in the following manner. Germination \[\xleftarrow{\,}\,{{P}_{730}}\,\underset{\begin{smallmatrix} [650\,nm] \\ \operatorname{Red}\,\lambda \end{smallmatrix}}{\mathop{\overset{\begin{smallmatrix} Far\,red\,\lambda \\ [730\,\,nm] \end{smallmatrix}}{\mathop{}}\,}}\,\,{{P}_{650\,\,}}\] \[\xrightarrow{\,}\] No germination
