Growth and carbon stock assessment in three year old fast growing trees grown under wasteland condition at Sivagangai district of Southern Tamil Nadu

Abstract

A field experiment was conducted to assess the growth and carbon sequestration potential of five fast growing trees namely Tectona grandis, Gmelina arborea, Dalbergia sissoo, Bambusa vulgaris var. vulgaris and Swietenia macrophylla. The saplings of these five species were planted and assessed for biometric, biomass production and carbon accumulation potential. Among the five tree species, Dalbergia sissoo and Bambusa vulgaris var. vulgaris were found to be superior interms of maximum height, basal diameter, biomass and biomass carbon. Gmelina arborea exhibited low height, basal diameter, biomass and biomass carbon. The per cent contribution of biomass carbon was higher in the stems of all the species followed by root, branches and leaves. The field study inferred that, Dalbergia sissoo and Bambusa vulgaris var. vulgaris performed well with higher biomass and biomass carbon productivity under dry land condition and hence these two species can be promoted for afforestation / reforestation of the wastelands in Tamil Nadu under protected irrigation conditions.

Potential of Plantation Trees for Biomass and Carbon Sequestration in Foothills of Jakanari Forest, Coimbatore, Western Tamil Nadu, India

“…Tectona grandis produced the most biomass carbon, 9.383 0.57 tonne ha -1 . Since the stem helped the tree develop through photosynthesis and ultimately stored the most food produced during photosynthesis by loading glucose molecule in wood components and hardening tissue as plants mature, the stem made up most of the biomass carbon in the tree (Hari Prasath et al 2016). The next best was observed in Dalbergia sissoo (8.859 ± 0.24 tonne ha -1 ) followed by Terminalia bellirica (5.623 ± 0.30 tonne ha -1 ), Albizia lebbeck (5.258 ± 0.28 tonne ha -1 ) and Gmelina arborea (5.057 ± 0.21 tonne ha -1 ).…”

Comparative Growth Performance and Eco-Physiological Response of Tree Species Grown Under Intensive Silvicultural Management Practices

“…The availability of water to plants and the ability of the plant to regulate water potential under climate change conditions will help to adapt species (Rouhi et al, 2007 andSouza et al, 2004). The plant's physiological character, such as transpiration and its control, is also an important factor in changing environmental conditions (Campose et al, 2011 andHari Prasath et al, 2016b).…”
