摘要
Flower color as the important economic indicator for ornamental plants has become the primary target for ornamental improving and breeding.Heavy ion mutation technology as a unique and efficient mutagen has been widely used in germplasm innovation and plant breeding.In our study,150 young shoots of Pelargonium were exposed to 80 MeV/u carbon ions and finally one stable genetic flower color mutant was obtained at dosage of 30 Gy.Comparing with wild type,the physiological indexes of mutant displayed significant differences.The color of petal in mutant was changed from red to light pink,and the color of peduncle and torus was changed from green to red,as well as the pistils and stamens’color were changed from yellow green to purplish red.
