In racemose inflorescence,___________.

Racemose inflorescences are indeterminate, meaning the main axis keeps growing and does not end in a flower. Because growth continues, new flowers are added at the tip while older flowers remain lower on the axis.

This pattern of flower production is called acropetal succession: the oldest flowers are situated at the base of the inflorescence and the youngest buds are positioned toward the apex.

Therefore, among the given statements, the one that correctly describes a racemose inflorescence is that flowers are borne in an acropetal succession. The other options are incorrect because:

• “the main axis terminates in a flower” describes a determinate (cymose) inflorescence, not racemose.
• “the growth is limited” contradicts the indeterminate nature of racemose growth.
• “flowers are solitary” ignores the clustered arrangement characteristic of racemes.

Hence, the correct completion of the sentence “In racemose inflorescence, _________” is: flowers are borne in an acropetal succession.
