Abstract: The investigation framed to study the effect of plant growth enhancing substances on plant canopy, vegetative growth and flowering as well as on overall appearance of Euphorbia milii plants grown in pot during 2015 – 2017. Application of silicon, spermine and salicylic acid at different concentrations found highly significant in influencing the growth, flowering, pigments as well as overall appearance of Euphorbia milii plants during both the seasons as compared to untreated plants (control). Plants treated with 3.0 mg/l salicylic acid showed maximum plant height, plant spread, number of branches with thicker stems and maximum number of leaves experiment. Early flower bud initiation (20.23 & 20.39 days) and flower opening (7.73 & 8.16 days) was observed with application of spermine at 30 mg/l. Maximum number of inflorescence per plant and flowers per inflorescence with improved flower size were obtained from plants treated with 3.0 mg/l salicylic acid at 30, 60 and 90 DAS. Improved flowering period (165.68 and 174.22 days), delayed flower senescence (15.60 and 17.68 days) and maximum in situ flower longevity was observed in Euphorbia plants sprayed with spermine at 30 mg/l as compared to untreated plants. Maximum chlorophyll content (18.56 and 18.51 mg/l) in leaves was observed with application of silicon at 300 mg/l concentration during both the seasons. The highest overall appearance as pot plant (5) on visual basis was noted in Euphorbia plants sprayed with salicylic acid at 3.0 mg/l which was followed by salicylic acid at 2.0 mg/l and silicon at 400 and 300 mg/l as compared to untreated plants.
