fluorescence occurs in nanoseconds (ns, 10–9 s); however, photochemistry in photosynthetic organisms occurs more rapidly, in picoseconds (ps, 10–12 s). Thus, when the 1,000‐fold more rapid pathway of photochemistry is available, little fluorescence is observed and photosynthesis proceeds with high efficiency.

IAA synthesis

IAA biosynthesis is associated with rapidly dividing and growing tissues

Primary site of auxin synthesis are shoot apical meristem and young leaves

Root apical meristem also synthesize auxin

Young fruits an seeds also have high level of auxin
