Comparative phosphorus uptake profile of Bt transgenic and non-transgenic cabbage (Brassica oleraceae L.var.capitata)

Plant species may differ in phosphorus uptake pattern due to genetic modification. The objective of this research was to study the comparative phosphorus uptake pattern of Bt. Transgenic cabbage and Non-transgenic cabbage (Brassica oleraceae L.) through radioactive phosphorus. Phosphorus content in two types of cabbage plant was more or less equal i.e. the variation was statistically insignificant. The variation in % phosphorus derived from fertilizer and percent of phosphorus utilization by transgenic cabbage was statistically higher as compared to normal cabbage and it was statistically significant. In 50 and 75 days samplings, the phosphorus content in transgenic and normal cabbage was same i.e. this variation was not statistically significant. The dry matter yield, total phosphorus uptake, percent phosphorus derived from fertilizer and percent phosphorus utilization was higher in transgenic cabbage and all these were statistically significant.
