Abstract:Cyclobalanopsis glauca widely distributes in the subtropical area of China.Based on the measurement of the fruit length,width,volume and width/length,the variation of fruit size and its shape among 10 natural populations of C.glauca from the eastern subtropical zone was studied and the results are as follows:①There are significant differences in fruit length,width,volume and width/length among and within 10 populations of C.glauca The variation coefficients( CVs )of the fruit volume,the fruit w...
