The Influence of some Growth Regulators on the Seed Germination of Dendrocalamus strictus Nees

The influence of growth regulators IAA, IBA and NAA on the seed germination of Dendrocalamus strictus Nees at three different concentrations i.e., 100, 200 and 500 mg/l has been studied. The germination percentage, stem height, ischolar_main length, number of ischolar_mains and leaves per plant were recorded after one month of germination and after one year. The maximum germination (about 69%) was recorded in IBA while in control, it was 52%. On the basis of statistically analysed parameters, it was found that all the growth regulators IAA, IBA and NAA were statistically significant in terms of germination percentage; stem height, ischolar_main length, number of ischolar_mains and leaves per plant. As the parameters were recorded after one year, the plant height and number of tillers per plant were also found to be statistically significant. In terms of concentrations, all the concentrations were also statistically significant along with stem height and ischolar_main length. While these parameters i.e., plant height and number of tillers per plant were statistically non-significant after one year. The experiments were conducted in polysleeves with single seed in each sleeve.
