Studies on seeds germination and seedlings growth of Notopterygium incisum

Objective:To investigate the appropriate culture medium,process of seeds germination and seedlings growth,and optical measures for seedling management of Notopterygium incisum.Method:Germination time and duration,germination potential and germination ratio were determined through controlled temperature,photoperiod,culture medium and seedling depth in illumination incubators.Result:The appropriate temperature was 15℃,and the most suitable culture medium was A_6(mixture of sawdust,ver- miculite,charcoal,and perliet),and the most suitable semination depth is 1-1.5cm.Conclusion:High-qualified seedlings can be germinated through the dormancy-broken seeds,and soil and other culture mediums with high organic matter content and loosing texture axe suitable for germination and seedlings raising of N.incisum.
