Abstract
The relationship between moisture content biomass of Cunninghamia lanceolata,Pinus massoniana,Schima superba and Castanopsis carlesii was studied.The results showed thattree species and organs both had significant effect on moisture content(p<0.001).The moisture content of four kind of tree species follows the order Cunninghamia lanceolata>Pinus massoniana>Castanopsis carlesii>Schima superba.For Cunninghamia lanceolata,moisture content of leaves had a significant difference with that of stems、root、whole-plant(p<0.001),but there were no significant differences among organs of the rest of tree species(p>0.05).The organs’moisture content of Cunninghamia lanceolata and Pinus massoniana of coniferous seedlings showed roots moisture content was largest,leaves moisture content was minimum. The organs’ moisture content of Schima superba and Castanopsis carlesii of broad-leaved seedlings had different sequence,roots moisture content was also largest and stems moisture content was minimum.The moisture content of coniferous seedlings had a close relationship with biomass,however,the relationship between moisture content of broad-leaved seedlings and biomass depends on different plant species.关键词
