Senescence in detached betel leaves: role of the petiole.
Removal of the petiole from detached betel leaves delays onset of leaf senescence; the delay is nearly proportional to the extent of depetiolation. An agar diffusate from intact midrib or excised petioles induces normal senescence in depetiOlated leave.
