Studies on the preservative treatment of round bamboos by a new technique
1989 - IRG/WP 3536
Nature has offered a versatile and cheap material bamboo, which is generally found to grow principally in forest areas from sea level to about 400 m wherever suitable combination of ecological factors prevail. This potential renewable natural resource has been since times immemorial, exploited by mankind for a variety of purposes specially in developing countries like Asia, Africa and South Americ...

Effect of microfibril orientation of bamboo cell wall on soft rot penetration hyphae
1994 - IRG/WP 94-10087
The effect of microfibrillar orientation of bamboo (Phyllostachys virideglaucescence) cell wall on the development of soft rot (Chaetomium globosum) penetration hyphae was investigated. It was found that the soft rot penetration hyphae normally followed the microfibril angle of the cell wall. Bamboo cell walls have alternating broad and narrow lamellae with different microfibrillar angles. The mic...

Natural resistance of Bamboo (Bambusa sp.) to marine wood-borers in Goa waters (India)
1993 - IRG/WP 93-10032
The paper deals with the natural durability of Bambusa sp. against the attack of marine wood-borers in Goa waters. Test specimens of this species were completely destroyed within a short period of nine months due to severe attack of borers indicating its very low natural resistance. Wood-borers involved were Martesia striata (Linnaeus), Nausitora hedleyi Schepman and Lyrodus pedicellatus (Quatrefa...

Invasion and colonisation of bamboo culm material by stain and decay fungi
2002 - IRG/WP 02-10453
Two distinct stages of the fungal infection of bamboo culms can be identified: entry into the culm itself (invasion) and further colonisation by spread within the culm wall tissue. This laboratory study aimed to characterise different invasion strategies of a variety of fungi. Well-known isolates of white- (Coriolus versicolor, Schizophyllum commune), brown- (Coniophora puteana, Gloeophyllum tra...

Preservative treatment of two bamboo species Borak (Bambusa balcooa Roxb) and Talla (Bambusa tulda Roxb) by Boucherie method
2003 - IRG/WP 03-40262
Bamboo is widely used as a construction material in rural and urban areas of Bangladesh. It is perishable in nature and highly susceptible to the attack of borer, termites and fungi. As a result, bamboo products do not last long. This short life of bamboo is increasing demand thereby increasing pressure on our homestead and natural reserve of bamboo. For this reason, it is needed to make the bambo...

The development of soft rot decay in bamboo fibres
1992 - IRG/WP 92-1572
The development of decay by soft rot fungus Chaetomium globosum was investigated in young and mature culms of bamboo Phyllostachys virideglaucescens. Soft rot decay was influenced both quantitatively and qualitatively by the differing levels of lignification in the material. Weight loss was significantly greater in the younger culm compared with the older, more heavily lignified culm. The distribu...

Shockwaves in wood preservation
2005 - IRG/WP 05-40308
Shockwaves are strong perturbations in aerodynamics that propagate at supersonic speeds independent of the wave amplitude. Physically the occurrence of shockwave is always characterized in a fluid flow by instantaneous changes in pressure, velocity and temperature. In this paper we describe a new wood preservative injection system that has been developed utilizing the non-linear pressure spike beh...

Bamboo: A Material Rediscovered
2006 - IRG/WP 06-10577
Bamboo has resurfaced as a valuable raw material as an inexpensive substitute for wood and a variety of value added products for engineered composites. Being a fast growing material available in the tropics, its real value was not realized until recently. Property evaluation studies and efforts to develop processing methods were initiated in the bamboo growing countries in the nineteenth century....

Micromorphological Characteristics of Degradation in Bamboo Attacked by White Rot Fungus Lentinus edodes
2006 - IRG/WP 06-10575
In comparison with micromorphological works for wood decay, little known is about the decay pattern of bamboos by wood decay fungi. The present work was undertaken to understand the general degradation pattern of bamboo and the influence of polylaminate layers in bamboo fiber walls on the restriction of fungal decay. The weight loss of bamboo species Phyllostachys puberscens against the white rot ...
