Type: article
Abstract: Two experiment were carried out on Helichrysum bracteatum L. plant at the Experimental nursery of the Ornamental Hort.Dept., Fac.Agric., Cairo Univ., Giza, Egypt, during the two successive seasons (2014/15and 2015/16).The aim of this study was to investigate the effect of gamma irradiation flowering parameters and anatomical structure of leaves and flowers in two generations (M1and M2).The obtained results showed the following: Seeds of H. bracteatum L. were exposed to eight doses of gamma radiation (5-40 Gy).The low doses of gamma radiation increased No. of flowers and flowers diameter per plant in M1 and M2.Were obtained on many morphological variations in flowers color and leaves shape through two generations with doses 15, 20, 25, 30 and 35 Gy.Some flowering parameters and anatomical structure of leaves and flowers and to confirm the stability of some of the mutations were obtained during the second season.The variants of these selections were selection from plants treated with (15, 20, 25, 30 and 35 Gy) of gamma rays.
