Study on relationship between basic density and various group age of Gigantochloa Scortechinii

This research is to study on between physical properties which is basic density of bamboo species Gigantochloa scortechinii with various group ages. The bamboo sample has been harvested at FRIM Kelantan (Jeli). The group of ages that has been choose in this research are from age 1, 2, 3, 4 and 5. The basic density test was carried out by selecting sample in even number of internode starting from culm 2 until culm 26 with 3 replications of sample in each internode. This research was conducted by using the denisty meter to get the basic density. The average for the overall basic density has been recorded that bamboo was 5 years old have a higher basic density than the other bamboo from 1, 2, 3 and 4 years old. From this study, the basic density of bamboo at the bottom shows an increase, while in the central part of bamboo internode the basic density flactuate and decrease in basic density readings at the top of the bamboo through various stages of life. Through the reading of correlation that were calculated, there are only two different bamboos which value is significant, 2 and 5 year-old with the r-value 0.620 (p=0.024) and r-value is 0.809 (p=0.001) respectively. In conclusion, bamboo was 5 years old have a higher level of basic density and the coefficient of correlation is very significant and it was suitable to be harvested for use as a raw material in any product
