Abstract

The authors investigate the effects 01 three different substrates on physiological characteristics of Fagus longipetiolata seedlings with pot experiments in this study.The results show that emergence rate of F.longipetiolata seedlings planted in substrate of general garden soil mixed with common sand reaches to 93.33%,followed by those planted in general garden soil substrate,with emergence rate of 90%,and the rate of those planted in common sand substrate is the lowest,which is at 76.67%.F.longipetiolata seedlings planted in substrate of general garden soil mixed with common sand have the earliest first euphylla time of 26 days,maximum averaged euphylla number of 6 pieces,and the highest averaged plant height of 16.87 cm.They are remarkably superior to those planted in substrate of general garden soil,while common sand substrate is not suitable for the growth of F.longipetiolata seedlings.The experiments reveal that F.longipetiolata seedlings are fairly sensitive to substrates,and that F.longipetiolata seedlings planted in substrate of general garden soil mixed with common sand have the advantages of high germination rate and growth rate.
