Analysis on the Carbon Content of Different Organs of Rubber tree (Hevea brasiliensis) in Regeneration Priod
摘要
Abstract
By means of the harvesting method, we studied the carbon content in different organs of rubber trees (Hevea brasiliensis) in regeneration period. The results showed that the carbon content of aboveground organs of rubber trees decreased in the order: leaves (52.90% )>trunks (48.84%) Collaterals (47.46% )>barks (46.20% )>twigs (45.20%). The carbon content of leaves was significantly higher than those of other organs. The carbon content of different components of litter in rubber plantation decreased as the following order fruits (55.30% ) >deciduous (53.22%>flowers(51.25%)>deadwoods(47.81%), and with significant differences between any two components. The content of the withering sample of same kind of component was greater than that of fresh litter. The carbon content of roots with different diameters of rubber trees decreased as the order: large roots(49.40%)>fine roots (49.16%)>coarse roots(49.08%)>stump-roots(48.65%)>small roots(47.37%)>medium roots(46.94%). The total carbon rates of main organs accounting for whole rubber trees were leaves 21.79%, trunks 20.12%, roots 9.96%, branches 19.09% and barks 19.13%, respectively. The average carbon content of the rubber tree in regeneration was 48.55%.关键词
