Vegetative propagation of Azadirachta ninh thuanand Sterculiato serve plantation on sandy soil in dry regions

Abstract

The vegetative propagation of Azadirachta ninh thuanand Sterculiawill supply materials for re - planting on sandy soil in dry regions, reduce the cost of afforestation and surmount difficulty from seed store of these species because of high oil and resin content in the seeds. This paper introduced some of research results about cutting techniques of both species
including: selection of nursery bed,cutting’s quality and treating with stimulant. The results show that sandybed using is better than sandy : ash(rate 1 : 1) bed for cutting, because it’s rooted rate is 29% to compare 22% and meristem rate is 33.3% to compare 25%, even the long of roots is
better. The top of branches for cutting and IBA (500ppm) stimulant are suitable for Azadirachta ninh thuanpropagation, because rooted rate is 28% (T2G1) to compare 16.7% (T1G1) while NZM is good stimulant for cutting of Sterculiaand easy to buy in market
