Photosynthesis in higher plants

238035 The form of pigment which inhibits germination is

1

P_{760}

2

P_{730}

3

P_{650}

4 All of these

Explanation:

B The pigment phytochrome behaves the following way:
red wavelengths $(650 nm)$ and far- red wavelengths $(730 nm)$ stimulate and prevent seed germination, respectively.
Germination $\leftarrow P_{730} \overset{far red λ (730 nm)}{⇌} \to$ Nogermination
