Abstract
Botryodiplodia theobromae is the dominant fungus causing sapstain of rubber wood in Kerala. The source of nutrition during the development and growth of sapstainfungus in wood is normally recognised as soluble carbohydrates wood extractives and proteins. Even though considerable progress has been made in the past few decades towards understanding the chemistry of decayed wood no details are available on the chemistry of sapstained wood. Hence an attempt was made to study the chemical changes occurring in rubber wood stained by B. theobromae in comparison with fresh rubber wood. Chemical properties such as alcohol-benzene extractives lignin and holocellulose percentage and amount of carbohydrate present in the cells were estimated and compared with that of unstained wood. No significant changes in the percentage of alcohol-benzene extractives lignin and holocellulose were observed in stained wood samples when compared to unstained wood samples. However there was a significant reduction in the carbohydrate percentage of stained wood samples.
