Rapit identification of wood of garden species in Vietnam by macroscopic features

Abstract

Some species of garden trees such as Mango (Mangifera indica), Sau (Dracontomelon duperreanum), Dau gia xoan (Allospondias lakonensis), Jackfruit (Artocarpus heterophyllus), Litchi (Litchi chinensis), Longan (Dimocarpus longan), in addition to fruiting, are also a source of wood that is currently used in construction, common woodworking and even fine art furniture and that is why there is a need for quick identification of the above species by macroscopic features of wood. Refer to a number of published wood structure description documents, observe the archived wood samples for re-examination or new description (for undescribed wood species), and take photos of the wood structure, we introduce documents to quickly identify 6 wood species of garden plants mentioned above. The most characteristic structural features of each wood species are as follows: Wood of Mango: vessels solitary and in multiples, axial parenchyma aliform, confluent, tyloses sclerotic, axial parenchyma banded and in narrow bands. Wood of Sau: Vessels solitary and multiples (to 3 vessels, rare to 4 vessels); tyloses sclerotic. Wood of Dau gia xoan: vessels solitary and multiples or semi-ring-porous, sometimes small vessels group at the end of the late wood. Wood of Jackfruit: basically light yellowish, vessels solitary and multiples, white deposits in vessels, axial parenchyma aliform, confluent. Wood of Longan: vessels solitary and multiples or semi-ringporous, wood surface smooth. Wood of Litchi: pink brown, vessels solitary and multiples; white deposits in vessels; wood surface smooth
