Research on propagation of Celastrus hindsii Benth.et Hook by cuttings in Binh Thanh commune, Cao Phong district, Hoa Binh province

Abstract

Celastrus hindsii Benth. is a medicinal plant with many medicinal values (effective in treating hepatitis, stomach disease, boils, cancer, anti -HIV virus). The species is also considered as a plant with high economic value in some localities of Hoa Binh province. Currently, the demand for the use of Celastrus hindsii is increased, particularly for the germplams that originating in Hoa Binh province. Ho wever, due to containing oil in seeds, the ability of regeneration from seeds is poor, leading to the risk of its depletion in the natural habitat. In this study, the research on propagating of Celastrus hindsii by cuttings was carried out in Binh Thanh commune, Cao Phong district, Hoa Binh province in order to provide scientific foundations for the supply of good quality seedlings of Celastrus hindsii and contributing to sustainable livelihoods for the local people. The results showed that treatment of cuttings with NAA at a concentration of 2,000 ppm had the best achievements (after 60 days, the survival rate reached 83.33%, the rooting rate was 74.41%, the average number of roots obtained 7.23 roots/cutting, the average length of the longest roots was 5.82 cm, and the rooting index got 42.08). In addition, the appropriate season of cuttings is in spring (after 60 days, the survival rate was 80.71%, the rooting rate was 72.43%, the average number of root reached 6.21 roots/cutting, the average length of the longest roots was 5.14 cm, and the rooting index obtained 31.62). Regarding the type of cuttings, the middle position cutting gave the best results (after 60 days, the survival rate and rooting rate reached 75.02% and 72.23% respectively; the average numb er of roots was 5.89 roots/cutting, the average length of the longest roots reached 4.76 cm and the rooting index was 28.03).
