Performance evaluation of different tree species for carbon sequestration under wasteland condition

Abstract

A study was conducted to identify suitable fast growing trees under wasteland condition for carbon sequestration.\rAccordingly, five fast growing trees namely Tectona grandis Linn. , Gmelina arborea Roxb., Dalbergia sissoo Roxb., Bambusa\rvulgaris var. vulgaris and Swietenia macrophylla king were selected for field study under wasteland condition. The performance\rof these trees was assessed with biometrical traits (height, basal diameter) and eco-physiological traits (transpiration,\rphotosynthesis, intercellular CO2 concentration and stomatal conductance). Among the five species, Dalbergia sissoo exhibited\rhighest growth, productivity and also superior in ecophysiological traits suits for carbon sequestration. The tree species,\rBambusa vulgaris var. vulgaris performed well next to Dalbergia sissoo interms of biometric, productivity and eco-physiological\rparameters. The lowest biometric and productivity was observed in Gmelina arborea. The tree species, Dalbergia sissoo and\rBambusa vulgaris var. vulgaris are highly suitable for afforestation in wastelands to attain carbon sequestration benefits.
