| Abstract: | The sex ratio and seed traits of Acer negundo populations growing on different streets were investigated in Changchun city.The results showed that the sex ratio was significantly different among different populations,though male individuals were more than females.There were different or significantly different morphological traits,such as seed size and opening angle of samaras.The seed plumpness varied between 33.8%~84.1%.The thousand seed weight varied between 30.3~5.6 g,with average weight at 36.0 g,the d... |
