Comparative study of various pretreatment on seed germination of Dalbergia cochinchinensis
Dalbergia cochinchinensis belongs to family Fabaceae, is a hardwood tree species listed as vulnerable on the IUCN Red List of Threatened Species. This species is a slow-growing and it is threatened by overexploitation for its timber and illegal logging. Because of the increased demand for the timber...
