Bismarckia nobilis is an oldest solitary silver blue fan palm of tropics and subtropics areas all through the world. A slow growing elegant ornamental, has currently a strong world demand as an outdoor plant in landscape industry from past twenty years. It is ideal for both domestic and commercial gardens as single specimen are also attractive and well suited for most of the residential landscape but seed germination is quiet slow and unequal. Thus the aim of present study is to assess the effect of seed priming method using different concentration of gibberellic acid (750mg/L, 1000mg/L, 1250mg/L) and imidacloprid (4g/kg, 6g/kg and 8g/kg) on bismarckia nobilis seed by breaking dormancy to get early germination. The following growth attributes like germination rate, germination percentage, plant height, leaf area, number of leaves and chlorophyll contents were studied in this experiment. The results demonstrate that priming among all the treatments of imidacloprid @ 6g/kg showed marked influence on plant height, leaf area, germination rate whereas gibberellic acid @ 1000 kg/L revealed maximum germination percentage but no effect on chlorophyll content was studied through these chemicals. Based on the results, imidacloprid being a cost effective chemical could be used as pre-treatment for inducing early germination in bismarckia nobilis seed as compared to gibberellic acid.
