Culm characteristics and volume-weight relationship of a forest bamboo (Melocanna baccifera (Roxb.) Kurz) from northeast India

Abstract

Culm characteristics of Melocanna baccifera, locally 'muli', culms at five different culm ages of 11 girth classes (5-6 to 15-16 cm) were studied from Cachar District of southern Assam, northeast India. We recorded internode length, internode diameter, number of internodes per culm, total culm height, total culm green weight and total culm volume of all five culm age classes. Data were gathered on 165 culms, each culm age class containing 33 culms with 3 culms per girth class. Culm height ranged from 3.2 to 15.3 m with highest mean of 9.15 m (in threeyear old culms) and maximum culm height was recorded in four-year old culms. Highest mean and maximum internode length (27.45 and 54.2 cm, respectively), internode diameter (3.12 and 4.75 cm, respectively) and total culm green weight (5.42 and 12.87 kg/culm, respectively) were recorded in three-year old culms and lowest in current-year culms. Best fitted regression models for all parameters were developed. Significant linear relationships between culm green weight and culm solid volume were documented for all five culm age classes. Their corresponding best-fit regression models were also developed.

Biomass, carbon stock and sequestration potential of Oxytenanthera abyssinica forests in Lower Beles River Basin, Northwestern Ethiopia

“…However , plants like bamboo have an extraordinary capacity to absorb CO 2 from the atmosphere [ 12 – 14 ]. Bamboo is one of the fastest-growing plants [ 15 ], with growth rates ranging from 30 to 100 cm per day and a harvesting cycle of 3 to 5 years, compared to 10 to 50 years for most timber species [ 16 – 19 ]. On account of their fast growth and short harvesting cycle, bamboo forests have been known to have higher C storage per hectare than fast-growing tropical and sub-tropical trees under comparable conditions [ 7 , 12 , 18 ].…”

Internode morphometrics and allometry of Tonkin Cane Pseudosasa amabilis

“…Moisture content constitutes a significant part of culm weight and declines along the culm of Gigantochloa scortechinii and Bambusa vulgaris , which can affect the dimensional stability and the strength of bamboo culm (Anokye et al., ). The relationship between the solid volume and green weight of the culm for Melocanna baccifera is linear (Singnar, Nath, & Das, ). Moreover, many studies have focused on the morphological characteristics of shooting and growth rhythm for specific species, such as Bambusa wenchouensis (Su et al., ), Dendrocalamus latiflorus (Zhou, ), Bambusa distegia (Zhang, Dong, Zhu, Zhu, & Sheng, ), Dendrocalamus hamiltonii (Li et al., ), and Bashania fargesii (Tian, ).…”

Influence of Age and Harvesting Season on The Tensile Strength of Bamboo-Fibre-Reinforced Epoxy Composites

“…The mechanical behaviour of bamboo fibres is required to improve developments in bamboo fibre polymer composites, which will require data on elementary fibre properties. While many other investigations were conducted in this area, the majority of them concentrated on mechanical differences at the single-fibre scale concerning age or location in bamboo culms [20]. The bamboo plant is the fastest-growing and most renewable plant that reaches its full growth in just a few years because the maturity cycle of bamboo is 3 to 4 years long.…”
