Leaf variation due to 2, 4-D influence inTrigonella foenum-graecum L

  • K. Unnikrishnan

Pretreatment of seeds ofTrigonella foenum-graecum L. with 2 ppm 2, 4-D induced seven patterns of abnormalities resulting from fusion and proliferation of leaflets. Vascular nature of abnormal leaf primordia and petioles are correlated to the morphological abnormalities. The size of leaf buttress or primordium at the time of pretreatment is critical in bringing about the abnormalities. Whenever the external stimulus (applied 2, 4-D) prevails upon the internal stimulus, leaf abnormalities result.
