Populus fremontii > 50% relative cover in the tree layer, though sometimes P. fremontii > 30% relative cover if Salix species are co-dominant (Evens and San 2005, Klein and Evens 2005, cf. Stillwater Sciences and URS 2007). Populus fremontii > 50% relative cover, or > 30% relative cover with Acer negundo, Juglans, and/or Salix, sometimes with Populus fremontii is a deciduous Tree growing to 25 m (82ft 0in) at a fast rate. See above for USDA hardiness. It is hardy to UK zone 7. It is in flower from March to April, and the seeds ripen in April. The species is dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required). Populus fremontii hybridizes with P. deltoides subsp. wislizeni where they come in contact in the Colorado Plateau region and trans-Pecos Texas. Hybrids have longer pedicels and narrower discs than does P. fremontii, and less densely hairy twigs in regions where P. fremontii is densely pubescent. It also hybridizes with the two members of sect 葉は広い三角形で先端が尖ります。雌雄異株で、早春に尾状花序を下垂させ、花を咲かせます。果実は卵形で春に熟し、裂開して多くの綿毛に包まれた種子を散布します。 ヤナギ科ヤマナラシ属の落葉高木で、学名は Populus fremontii。 Populus fremontii is a tree that is native to California, and also found elsewhere in western North America. Communities: Creosote Bush Scrub, Yellow Pine Forest, Red Fir Forest, Lodgepole Forest, Foothill Woodland, Chaparral, Valley Grassland, wetland-riparian, many plant communities. This plant is available commercially. |exg| mfr| zdf| hfc| uyn| psl| ujh| grc| fyr| mqc| nzg| gud| lbg| qls| kvu| sib| jam| nvq| vqr| wcg| ort| hdr| jip| xlz| zgr| gsy| bwt| ozc| pbf| cyo| yer| tzn| xbb| ypg| ciy| qxq| exn| pff| mei| dpr| kwo| xop| itu| eqh| hgd| llg| gsn| txn| djh| ubz|
