Would a defoliated plant respond to a photoperiodic cycle? Why?

(NO) defoliated plant will not respond to the photoperiodic cycle.
It is hypothesized that the hormonal substance responsible for flowering is synthesized in the leaves. This substance subsequently migrates to the shoot apices and modifies them into flowering apices.
Therefore,in the absence of leaves,the perception of light does not occur,and the plant fails to respond to the photoperiodic stimulus.
