- Abstract
[Objectives] The paper was to study the cutting propagation technique of Pennisetum purpureum Schum and to provide a technical reference for establishing an efficient cutting propagation method. [Methods] Six treatments were set up using P. purpureum cv. Guiminyin and P. purpureum cv. Guimu-1 as test materials, including 1-node oblique insertion, 1-node oblique insertion c rooting powder, 1-node transverse burial, 2-node oblique insertion, 2-node oblique insertion c rooting powder and 2-node transverse burial. The following indices were observed and determined for P. purpureum cuttings: emergence rate, rooting rate, root number, longest root length, fresh root weight, plant height, number of tillers, number of leaves, and fresh stem and leaf weight. [Results] In the 2-node cutting c rooting powder treatment, Guiminyin and Guimu-1 exhibited the highest survival rate, root growth indices, and stem and leaf growth indices, with the emergence rates of 94.29% and 90.26%, respectively. The 2-node cutting treatment followed closely behind, while the 1-node cutting treatment had the lowest indices. Under the same treatment, Guimuyin exhibited higher mean values for plant height, number of leaves, fresh stem and leaf weight, longest root length, and fresh root weight compared to Guimu-1. However, it had lower mean number of tillers, and emergence rate and rooting rate of the 1-node cutting treatment compared to Guimu-1. [Conclusions] The P. purpureum cuttings thrived in the 2-node cutting c rooting powder treatment, and the overall cutting effect of Guiminyin was superior to that of Guimu-1.
