RESPONSE OF CAMBIUM GROWTH TO MECHANICAL INJURIES IN TREE SPECIES

Abstract

The major objective of the study was to understand regrowth after an injury in 11 tropical tree species such as Albizia lebbeck, Azadirachta indica, Delonix regia, Lannea coromandelica, Madhuca longifolia, Pongamia glabra, Peltophorum pterocarpum, Terminalia catappa, Senna siamea, Syzygium cumini and Terminalia arjuna. The study was conducted from January 2019 to January 2020 at the Agricultural College and Research Institute, Tamil Nadu Agricultural University, Madurai, India. In the experiment, wood incision with a dimension of 15 cm × 15 cm was made on the outside of the tree trunks and its growth was calculated by graph paper drawing method. The results indicated that Lannea coromandelica which has no timber value, exhibited the fastest cambial growth compared to the other tree species.
