TAILIEUCHUNG - Research on reproductive characteristics and multiplication measures of vetiver grass in Thua Thien Hue

This article introduces some results on reproductive characteristics and methods of asexual propagation by cuttings in Hue Vetiver cuttings under the action of some growth regulating substances. | JOURNAL OF SCIENCE, Hue University, Vol. 67, No. 4A, 2011 RESEARCH ON REPRODUCTIVE CHARACTERISTICS AND MULTIPLICATION MEASURES OF VETIVER GRASS IN THUA THIEN HUE Nguyen Minh Tri1, Nguyen Dac Tao1 1 College of Sciences, Hue University Nguyen Ba Loc2 2 College of Education, Hue University Abstract. Vetiver grass - Vetiveria zizanioides (L.) Nash has been planted on the banks of some main rivers in Thua Thien Hue province (Huong river, Xuoc Du river, Bo river.) to prevent landslide. However, its current range of use seems to be restricted. It may be due to the shortage of materials and the fear that it might possibly develop into a kind of environmental weed. In this circumstance, the study attempted to prove the non-invasive nature of vetiver and develop a suitable protocol for its propagation. The results revealed that its flower is bisexual, unisexual or asexual. It appears from June to November. Vetiver seeds after physiological maturation could not germinate on both artificial conditions suggested by Murashige Skoog (1962) and natural soil. Meanwhile, the seedlings could sprout from the original form of the mother plant. The breeding of vetiver by separating the single bud cuttings and put into PE bags offered a higher ratio of living plant and better ability to form roots compared to traditionally propagating the bare root buds. This makes breeding simpler and easier to be put into practice, but some disadvantages remain such as the requirement of a large shoot source and areas, the high cost of labor and the low uniformity of created seedlings. Faced with this situation, NAA, one of the plant growth regulators, was used to stimulate the roots of the cuttings. At the concentration of 500 ppm, the ratio of forming roots and the average number and length of roots were the highest in the cases of tender and mature cuttings. Therefore, it is possible to use the mature or flower stem as a source of breeding materials for producing a large number of seedlings .
