Effect of gamma radiation on various growth parameters and biomass of Canscora decurrens Dalz
Author(s): V Yadav
Abstract: In the present study, seeds of C. decurrens were exposed to gamma radiation at doses (5, 10, 15, 20, 25, 30, 35, 40, 45 and 50kR) to examine its effects on growth traits and morphological variation. The various physiological effects were observed on germination, no. of plant survived, shoot induction, ht. of plant, ht. of root, no. of nodes and leaves, fresh weight and dry weight. Gradual reduction was observed in no. of plant survived with increased the doses similarly earlier germination and shoot induction were recorded at lower doses. Lower doses 10, 15, 20 and 25kR showed stimulation in seedling shoot and root length, no. of nodes and leaves as well as fresh weight and dry weight where as reduction was observed in 30, 35, 40, 45 and 50kR. Various morphological variants like stem thickening, more no. of nodes with shorter internodes, increase in leaf size and area were also observed etc. This paper summarizes and discusses the effects on different growth parameters and biomass attainment through the use of ionizing radiation in C. decurrens.
