Improvement of Propagation by Hardwood Cuttings With or Without Using Plastic Tunnel in (Quisqualis indica)

Quisqualis (Quisqualis indica) is an important ornamental plant, which is known to be difficult to propagate under dry arid condition of Khartoum State, in Sudan. Stem cuttings of the plant were subjected to different treatments, comprising season of cutting (winter, summer or karif,'' the rainy season'') and level of humidity (using plastic tunnels).The experiment was carried out under the normal nursery conditions to determine the best conditions for growth and development of stem cuttings of plant. The results revealed that the winter season gave the best performance in number and length of both roots and leaves of the cuttings. Plastic tunnels with water mist gave the best rooting and vegetative growth followed by the cutting under plastic tunnels without mist, irrespective of season.The control treatment(not under plastic cover) gave the poorest results.
