Research progress on breeding techniques of national grade Ⅱ protected plant,Dalbergia odorifera T.Chen
摘要
Abstract
Dalbergia odorifera T.Chen,commonly known as fragrant rosewood,is an evergreen semi-deciduous tree belong-ing to the genus Dalbergia in family Fabaceae,and is naturally distributed only on Hainan Island.It is listed as a national grade Ⅱ protected plant in China.It is not only an important strategic resource but also a precious medicinal and aromatic spices.Due to irrational logging practices and extensive illegal logging,the wild resources of D.odorifera are nearly depleted.Additionally,there has been a persistent imbalance between supply and demand for D.odorifera globally,leading to continuously rising mar-ket prices,reaching a point where it is priced per pound and difficult to find.Furthermore,the heartwood formation of D.odor-ifera in the wild takes a long time,typically around 7 years to initiate heartwood formation,and maturity requires more than 30 years.Therefore,research on breeding techniques for D.odorifera can not only meet the growing market demand but also alle-viate the pressure of its remaining natural resources from illegal logging.In recent years,scholars both domestically and interna-tionally have conducted extensive research on the breeding techniques of D.odorifera and have achieved fruitful results.Based on this,the current paper reviewed the research progress of breeding techniques for D.odorifera,including sexual reproduction(seed germination,seedling growth),asexual propagation(cuttings,grafting,tissue culture),and targeted cultivation in artifi-cial forests(growth regulator injection,microorganism inoculation,and planting management measures).Additionally,it ana-lyzed the main problems existing in the development of D.odorifera industry,such as insufficient high-quality germplasm re-sources,lack of efficient cultivation and targeted breeding techniques,insufficient research on the material basis of new variet-ies,and non-systematic exploration of active ingredients.Finally,this paper proposes research prospects such as increasing the breeding of new varieties,innovating cultivation technology systems,and upgrading the industrial chain structure.This re-view can provide references for the research on high-quality seedling breeding techniques for D.odorifera.关键词
